With the ‘Off’ setting there’s a fair amount of ‘powdery’ trailing. Compared to frame rates up at the top end supported by the monitor, there was both a decrease in ‘connected feel’ and an increase in overall perceived blur as the frame rate dipped. The ‘Weak’ setting slightly reduces this, whilst the ‘Medium’ setting offers a further reduction. We did not observe any static interlace patterns, although we did observe some dynamic ‘interlace pattern artifacts’. The ‘IPS glow’ was still a feature, though, and contrast in general is certainly an area in general where VA models are worthy of more praise than IPS-type panels. There was also ‘IPS glow’ which ate away at detail peripherally. Because the gamut is expanded, shades maintain good spacing so things don’t appear artificially ‘bumped up’ in saturation at the expense of shade variety. With ‘VSync off’ the frame rate is free to climb as high as the GPU will output (potentially >144fps). You’ll also notice ‘G-SYNC Compatible’ listed under ‘Monitor Technology’ in this section, as shown below. Both our responsiveness article and the G-SYNC article linked to explore the importance of these two elements being synchronised. Further up you can see it in front of the object as well as behind. They may appear as an interference pattern, mesh or interlaced lines which break up a given shade into a darker and lighter version of what is intended. Some temporal dithering was evident on some of the lighter blocks, but this was finely controlled and well-masked.Performance on the white saturation test was very good. So it isn’t ideal, but can be used to give a reliable emulation of the sRGB colour space for non-colour managed workflows. A ce prix là, c'est tout simplement une référence ! The C24G1 reference shot shows this to a fair extent behind the UFO body, but much less so behind the main UFO body. The AOC provided a decent cinematic look to the film overall, with bright elements contrasting well against darker surroundings. Ecran PC. The resolution doesn’t provide the same sort of clarity and detail levels as higher resolutions nor the same ‘desktop real estate’. The monitor itself must support ‘VESA Adaptive-Sync’ for at least one of its display connectors, as this is the protocol that FreeSync uses. This requires that the frame rate comfortably exceeds the refresh rate, not just peaks slightly above it. There is really only a faint whiff of this sort of trailing remaining using this setting. 25g2u is a newer one, has usb hub, and comes with a display port cable and thats all the difference i know. We preferred a setting of ‘15’ as this provided what we consider an optimal mixture of brightness and clarity. This is a title with plenty of high-contrast scenes – or, at least, scenes that show contrasting content and look their cinematic best on models with strong contrast. However; an LFC-like technology was supported, with the monitor keeping at a multiple of the frame rate with its refresh rate. This indicates a relatively low viewing angle dependency to the gamma curve of the monitor, characteristic of an IPS-type panel. An additional point to consider is that the backlight flickers at a frequency matching the refresh rate of the display, which could bother sensitive users. It put in a very competent 144Hz performance, with low input lag and good overall pixel responsiveness. It was quite well set up out of the box, delivering a punchy and vibrant image with excellent shade variety and fairly strong colour consistency. Home › AOC › 24G2U. We may earn a commission when you buy through links on our site. Where possible, the monitor dynamically adjusts its refresh rate so that it matches the frame rate being outputted by the GPU. The monitor runs at ~100Hz (matching the frame rate) with Adaptive-Sync active, removing the tearing and stuttering from the mismatches that otherwise occur. Simply because they are used to help the website function, to improve your browser experience, to integrate with social media and to show relevant advertisements tailored to your interests. The ‘IPS glow’ was still a feature, though, and contrast in general is certainly an area in general where VA models are worthy of more praise than IPS-type panels. But the ‘IPS glow’ is certainly still present and affects the dark regions of this title, if viewing in dimmer lighting conditions. There is also a fair amount of trailing behind the object and in some cases in front of it, however. We made similar observations on Shadow of the Tomb Raider. The overall design of the monitor has enough subtle hints of dark red to be ‘interesting’, without anything that really screams “gaming screen” too loudly and proudly. Passer à la navigation principale We found it accelerated visual fatigue and preferred the normal flicker-free operation of the monitor, but sensitivity to flickering varies. You can again see varying degrees of trailing behind the object. Many gamers are comfortable with a screen size of around 24” and are seeking an affordable solution with a good mixture of image quality and responsiveness. The following AOC manuals are currently available for download. The purple block appeared a bluish purple throughout. Shades were noticeably more consistent than on VA and moreover TN panels, overall, with relatively good saturation levels maintained throughout the screen.Further observations were made using the animated TV series Futurama. There was a brief stuttering when this activated, but this isn’t something users should find bothersome unless things are frequently going above or below the LFC boundary. For the mixed image you can see things a bit of a contrast loss and brightness shift particularly from sharper angles. It was quite well set up out of the box, delivering a punchy and vibrant image with excellent shade variety and fairly strong colour consistency. This gets rid of the overshoot and is well-tuned for such refresh rates. But the well-tuned and flexible pixel overdrive gave a suitable option for a broad range of refresh rates. Minimal bezel distraction for the ultimate battle station. The 24G2U (24G2)’s ‘Strong’ overdrive setting, which we prefer for refresh rates at the top end, still worked well at ~100Hz. The following image was taken a few metres back to eliminate ‘IPS glow’. The AOC 24G2U (24G2) offers this, with a 23.8” screen size. Luminance uniformity mapThe SpyderX Elite was also used to analyse variation in the colour temperature (white point) for the same 9 quadrants. In the central region of the screen the strobe crosstalk becomes somewhat stronger and there’s essentially another repetition of the object as you move further down again. The 24G2U (24G2) uses DC (Direct Current) to dim the backlight and does not use PWM (Pulse Width Modulation) at any brightness setting. This is a title where dimly lit interior locations, such as small passageways and caves are common. The pixel response requirements for optimal performance are stepped up quite a bit now, so the trailing behind the UFOs appears a bit different – extending further back in places an existing where it didn’t before. The 24G2U (24G2) supports FreeSync via DP 1.2a and HDMI 1.4 on compatible GPUs and systems. This value is influenced both by the element of input lag you ‘feel’ (signal delay) and the element you ‘see’ (pixel responsiveness). The deviation between each quadrant and the quadrant closest to the 6500K (D65) daylight white point target was analysed and a DeltaE value assigned. The C24G1 shows some fairly bold trailing for the dark background and overshoot elsewhere, whilst the XG240R shows some more extended ‘powdery’ trailing for the medium background at 60Hz. There was a slight red striping at the bottom of the screen and a slight green tint to the striping further up. Individual targets depend on individual uses, tastes and the lighting environment, however. The video below shows the Lagom text test, a mixed desktop background and dark desktop background from a variety of viewing angles. Some of the woody hues and earthy brown shades had a bit too much of a red hue, due to the colour gamut, whilst some of the vegetation had a bit too strong of a bright yellowish green hue. At 144Hz, above, the UFO appears more sharply focused and slightly narrower, indicating a further decrease in perceived blur due to eye movement. As noted earlier, AMD FreeSync makes use of Adaptive-Sync technology on a compatible monitor. The maximum luminance was recorded at ‘quadrant 5’ in the centre of the screen (165.3 cd/m²). We also made some observations using the film. We explore this and some other aspects to consider using in-game examples at the end of this section. We used this monitor whilst playing a variety of game titles, with FreeSync active. It reduces the blue colour channel compared to factory defaults and slightly lowers the colour temperature. You can see moderate to strong strobe crosstalk throughout the screen. Lagom’s tests for viewing angle tests were used to further explore colour consistency and viewing angle performance. Le test de l'AOC 24G2U (ou 24G2), un écran Gamer de 24 pouces 144 Hz avec une dalle IPS. When you open up Nvidia Control Panel, you should then see ‘Set up G-SYNC’ listed in the ‘Display’ section. We used this setting for our own viewing pleasure in the evenings, although not for specific testing beyond that involving this particular setting. The AOC C24G1 is a good example of a VA model that offered a nice mixture of image quality and responsiveness. If you activate the ‘Frame Counter’ in the ‘Game Setting’ section of the OSD, this will display the refresh rate of the display and therefore indicate the frame rate if ‘FreeSync’ is active and the frame rate is within the variable refresh rate range of the display. This cuts down on the gamut significantly, providing just a little under-coverage (98% sRGB) without over-coverage. Colour gamut 'Test Settings' The monitor also provides an sRGB emulation mode (setting ‘Color Temp.’ to ‘sRGB’ in the ‘Color Setup’ section of the OSD). The monitor also includes some ‘LowBlue Mode’ Low Blue Light (LBL) settings, accessible in the ‘Game Setting’ section of the OSD. The highest deviation was recorded towards the bottom right (DeltaE 4.3). Under our ‘Test Settings’ we recorded a very respectable 1400:1. The first few blocks blended into the background readily, which is appropriate for a monitor tracking the ‘2.2’ gamma curve. The rear of the monitor is mainly matte black plastic, with some dark red satin-finish plastic elements. The total depth of the monitor including stand is ~230mm (9.06 inches), with the screen sitting ~45mm (1.77 inches) back from the front edge of the stand. With the ‘Off’ setting there’s a fair amount of ‘powdery’ trailing. But the colour shifts are less pronounced overall than on VA or TN models. The first is the enhanced ‘connected feel’ you get when interacting with the game world. The brightness in the dark is too high, so a lamp as a backlight is a good idea, and the viewing angles are unworthy of an ips panel - but otherwise just about everything beats this screen. By eye we could see that this side of the screen and in particular the bottom right corner appeared noticeably cooler (higher colour temperature) than the rest of the screen, when viewing some lighter shades such as white. There is really only a faint whiff of this sort of trailing remaining using this setting. This includes a very slender panel border around the image, blending in seamlessly with the rest of the screen, plus a sleek black plastic outer component. As such, it looks its best where contrast performance is strong. We used this monitor whilst playing a variety of game titles, with FreeSync active. When a monitor is used in this way, it is something which Nvidia refers to as ‘G-SYNC Compatible’. This reflects a significant decrease in perceived blur due to eye movement. The environments appeared vivid with moderately high saturation levels, but varied at the same time and not completely unnatural and cartoonish. 92% DCI-P3 colour space coverage was recorded by our colorimeter. White in-game text inside a dimly lit building, for example. Some models are specifically validated as G-SYNC compatible, which means they have been specifically tested by Nvidia and pass specific quality checks. All warranties with respect to this information are disclaimed. It was not as pronounced as some of the TN or VA shifts you’d see from this sort of viewing distance, however. Increasing alertness and making it more difficult for the body to shut off. It was free from the sort of clear saturation shifts that occur at different sections of the screen for VA and moreover TN models. This model employs a medium matte anti-glare screen surface with a fairly smooth surface texture. This worked effectively to reduce tearing and stuttering. The image set below shows results with a slight bump up in refresh rate to 120Hz, MBR again active. Additional testing was performed using an AMD Radeon RX 580 and using HDMI, although observations for this table didn’t vary significantly between GPUs or inputs. The second benefit is a reduction in perceived blur due to eye movement, as demonstrated using Test UFO earlier. This overshoot became more noticeable if frame rate dropped significantly lower, below 80fps it became moderately strong in places. Straight from the box the monitor provided a fairly bright, vibrant and varied image. The monitor also provided a solid Adaptive-Sync performance, working well with both our AMD (FreeSync) and Nvidia (‘G-SYNC Compatible Mode’) GPUs to get rid of tearing and stuttering from frame and refresh rate mismatches. Compared to frame rates up at the top end supported by the monitor, there was both a decrease in ‘connected feel’ and an increase in overall perceived blur as the frame rate dipped. There was also some eye-catchingly colourful painted artifacts and suchlike. AOC Gaming 24G2 is in a class of its own, bringing brilliant colors of an IPS panel and the fast 1ms (MPRT) response time into one sleek battle machine for people who demand both uncompromising speed and image quality. The test is set to run at its default speed of 960 pixels per second, which is a practical speed for such photographs whilst highlighting key weaknesses well. The average deviation between each quadrant and the brightest recorded point was 6.88%, which is decent. The remaining blocks were distinct and showed good steps up in brightness. As an Amazon Associate I earn from qualifying purchases made using the below link. The first few blocks blended into the background readily, which is appropriate for a monitor tracking the ‘2.2’ gamma curve. This overshoot is not as strong or eye-catching as at 60Hz and has a rather blended appearance overall. Not all areas refresh simultaneously, so its appearance can differ depending on how high up or low down on the screen movement is being observed. It’s important to bear in mind that individual units and preferences vary, so these settings are just a suggestion and won’t be optimal in all cases. It indicates a low signal delay which shouldn’t bother even sensitive users. There were some slightly more pronounced weaknesses for some pixel transitions, involving very light shades (such as white) with certain darker shades in the background. There are also various amounts of trailing behind the UFOs, caused by weaknesses in pixel responsiveness. The strong static contrast, for the panel type, and the ‘IPS glow’ being slightly more subdued than normal helped in this respect. So far the high refresh rate options have centred around either TN models, built for speed, or VA models offering strong contrast and some improvements in colour handling at the expense of responsiveness. There are saturation, contrast and brightness shifts that are more noticeable on this model compared to some IPS-type models. Sitting closer to the screen exaggerates the sort of shifts explored here. Response times, color rendition and color range, calibration and uniformity, absent backlight bleeding and clouding: the quality offered is significantly higher than you'd expect for this price. Some of the key ‘talking points’ for this monitor have been highlighted in blue below, for your reading convenience. When the frame rate rises above 144fps, the monitor will stay at 144Hz and the GPU will respect your selection of ‘VSync on’ or ‘VSync off’ in the graphics driver. The final columns show some reference screens for comparison. We also look at ‘pursuit photography’, an image capture technique which uses a moving camera to capture motion on a screen in a way that reflects both elements of perceived blur. I bougth this 24G2U monitor since I recently upgraded graphic card and since all new GPUs have removed dual link dvi support which is required for my old gaming monitor, a Benq XL2411 in order to get 144hz refresh rate and playing on … This indicates excellent low perceived blur due to eye movement. If you hover over this, it will also report the variable refresh rate display supported by the display. These repetitions are due primarily to the pixel responses not keeping up with the rigorous demands of the refresh cycle. This becomes so strong towards the bottom of the screen that it melds into the object itself. An accomplished product with vibrant and varied colour output, pleasing contrast and responsiveness for an IPS-type panel and very attractive pricing. The image below shows the gamma curve under our ‘Test Settings’, making fairly minor adjustments compared to the factory defaults. There’s a faint ‘powdery’ trail behind the object for the dark and medium backgrounds, but this is slight and a clear improvement compared to the C24G1 reference. We also look at ‘pursuit photography’, an image capture technique which uses a moving camera to capture motion on a screen in a way that reflects both elements of perceived blur.The images below are pursuit photographs taken using the UFO Motion Test for ghosting, with the UFO moving across the screen from left to right at a frame rate matching the refresh rate of the display. Our test system runs Windows 10 and an Nvidia GTX 1080 Ti connected via the supplied DP cable. The video below summarises some of the key points raised in this written review and shows the monitor in action. As the frame rate of the content drops (and so does the refresh rate of the monitor), G-SYNC models with the module re-tune the pixel overdrive impulse appropriately – something referred to as Variable Overdrive. The Lagom text appeared a blended grey throughout without strong green or red tints to the striping. FreeSync models lack this and it’s common to see increasingly obvious overshoot if you just stick to using your response time setting that worked best at the much higher refresh rates. The following observations were made from a normal viewing position, eyes around 70cm from the screen. The AOC C24G1 using MBR (Motion Blur Reduction) and set to what we consider its optimal setting for that. With up to 2.4 times as much visual information being pumped out every second as a 60Hz monitor (or this monitor running at 60Hz), there are two key benefits. In fact it compares favourably to the reference shots in some respects. Explosions ripping through space, light sabers lighting up dark interior locations and suchlike. This is also true at ‘MBR = 15’, although the white notches again appear a bit more blended on the photo than in reality due to brightness and how the image was captured by the camera. There was not an obvious mask of graininess from the screen surface, just a light misty ‘dusting’.The greyscale gradient appeared smooth without obvious banding or dithering. As with other aspects of uniformity, it’s important to remember that individual units vary and that you can expect deviation beyond the measured points. The monitor also provided a solid Adaptive-Sync performance, working well with both our AMD (FreeSync) and Nvidia (‘G-SYNC Compatible Mode’) GPUs to get rid of tearing and stuttering from frame and refresh rate mismatches. The brightness was ~160 cd/m² at 144Hz, which is similar to what we target for our ‘Test Settings’ with MBR disabled. Some models are specifically validated as G-SYNC compatible, which means they have been specifically tested by Nvidia and pass specific quality checks. Some shades appeared somewhat deeper at the very edges of the screen, but this was not too pronounced from our preferred viewing position and could’ve been exacerbated by some of the uniformity issues on our unit. Well, i think that’s pretty obvious, yes. This is again a sort of look many would find inviting, but it isn’t universally appreciated. The final section of the video shows a dark desktop background and highlights ‘IPS glow’ mentioned earlier. Brighter shades contrasted well with darker surroundings, whilst the screen surface kept such shades appearing fairly smooth without obvious graininess. Some users prefer to leave VSync enabled but use a frame rate limiter set a few frames below the maximum supported (e.g. However; these weaknesses were nowhere near as pronounced nor as widespread as the sort of weaknesses you’d observe on VA models. The photo below gives a rough idea of how the Lagom text test appeared. We won’t be going into this in detail as it’s a GPU feature than a monitor feature. There is a significant step up in this respect comparing 60Hz to 144Hz. An additional point to consider is that the backlight flickers at a frequency matching the refresh rate of the display, which could bother sensitive users. With ‘VSync off’ the frame rate is free to climb as high as the GPU will output (potentially >144fps). Where possible, these links will automatically direct you to your nearest store. Some shades such as dark reds and medium blues appeared slightly deeper towards the extreme side edges of the screen, from our preferred viewing position (eyes ~70cm from the screen). But the well-tuned and flexible pixel overdrive gave a suitable option for a broad range of refresh rates. Explosions ripping through space, light sabers lighting up dark interior locations and suchlike. The AOC supports a variable refresh rate range of 48 – 144Hz. A sort of haze of light which lightens up darker shades peripherally, particularly towards the bottom corners from a normal viewing position. Sitting closer to the screen exaggerates the sort of shifts explored here. 23.8 inch; 1920x1080 pixels; A cable-tidy loop can be found towards the bottom of the stand neck. There are saturation, contrast and brightness shifts that are more noticeable on this model compared to some IPS-type models. The included stand is attached with a quick-release mechanism and can be easily removed using by pressing the button beneath the port attachment point. A sort of haze of light which lightens up darker shades peripherally, particularly towards the bottom corners from a normal viewing position. A sort of ‘sheen’ or hazing which develops on the screen off-angle more quickly than you might expect for the panel type. The monitor also provided a solid Adaptive-Sync performance, working well with both our AMD (FreeSync) and Nvidia (‘G-SYNC Compatible Mode’) GPUs to get rid of tearing and stuttering from frame and refresh rate mismatches. Note that the relatively high saturation of the UFO colours caused the segments to appear slightly more blended in the photos for the G2 than they do in reality – the segmentation appears a little more distinct (like the reference shots) in person. You’ll also notice ‘G-SYNC Compatible’ listed under ‘Monitor Technology’ in this section, as shown below.
