About this deal

Pleasing contrast for the panel type and a relatively smooth screen surface finish, delivering a decent atmosphere for darker scenes and fairly smooth-looking lighter shades Vibrant and varied colour output straight from the box with a generous colour gamut and fairly strong colour consistency As shown above, the monitor uses the standard RGB (Red, Green and Blue) stripe subpixel layout. This is the default expected by modern operating systems such as Microsoft Windows and Apple MacOS. You needn’t worry about text fringing from non-standard subpixel layouts as a Mac user and don’t need to run ClearType as a Windows user. You may still wish to run through the ClearType wizard and adjust according to preferences, however. The subpixel layout and arrangement is normal and we had no subpixel-related concerns related to sharpness or text clarity on this model. The AOC 24G2 FreeSync range is 48-144Hz, and it works with compatible NVIDIA GPUs without issues as it’s officially certified as ‘G-SYNC Compatible.’ Since this is a 24″ display, 1080p resolution provides a decent pixel density of 92.56 PPI (pixels per inch), which results in plenty of available screen space and sharp non-pixelated details.

The OSD (On Screen Display) is controlled by pressable buttons beneath the right side of the bottom bezel. A small forwards-facing power LED is also included in this region, to the right of the buttons. This glows white when the monitor is on and amber when it enters a low power state (signal to the system is lost). The video below explores this menu system. VSync is configured in the ‘Gaming’ section of ‘Radeon Settings’, where it is referred to as ‘Wait for Vertical Refresh’. You can either configure this globally under ‘Global Settings’ or for each game individually. The default is ‘Off, unless application specifies’ which means that VSync will only be active if you enable it within the game itself, if there is such an option. Such an option does usually exist – it may be called ‘sync every frame’ or something along those lines rather than simply ‘VSync’. Most users will probably wish to enable VSync when using FreeSync to ensure that they don’t get any tearing. You’d therefore select either the third or fourth option in the list, shown in the image below. The final option, ‘Enhanced Sync’, is a relatively new addition to the driver. This is an alternative to VSync which allows the frame rate to rise above the refresh rate (no VSync latency penalty) whilst potentially keeping the experience free from tearing or juddering. This requires that the frame rate comfortably exceeds the refresh rate, not just peaks slightly above it. We won’t be going into this in detail as it’s a GPU feature than a monitor feature.Note that the ‘Overdrive’ setting can be adjusted under MBR. However; ‘Strong’ is the only usable setting. The others are simply too slow and increase trailing and strobe crosstalk significantly without providing any benefits – we just focus on the ‘Strong’ setting here. Also be aware that setting the ‘Overdrive’ to ‘Boost’ is equivalent to using the ‘Strong’ setting and setting ‘MBR’ to ‘20’. We test MBR ‘15’ here as well, as we consider it to give a good mixture of brightness and clarity. The brightness was ~160 cd/m² at 144Hz, which is similar to what we target for our ‘Test Settings’ with MBR disabled. You will also see in the image above that it states: “Selected Display is not validated as G-SYNC Compatible.” This means Nvidia hasn’t specifically tested and validated the display, not that it doesn’t work. This model worked properly using Adaptive-Sync (G-SYNC compatible mode) on our Nvidia GTX 1080 Ti, offering an experience that was very similar to using AMD FreeSync. A slight difference is that the floor of operation appeared to be 60Hz (60fps) rather than 48Hz (48fps). However; an LFC-like technology was supported, with the monitor keeping at a multiple of the frame rate with its refresh rate. There was again a momentary stuttering as the boundary was crossed, as we observed with our AMD GPU as well. We used a small tool called SMTT 2.0 and a sensitive camera to compare the 24G2U (24G2)’s latency with a screen of known latency. To help maximise accuracy, over 30 repeat readings were taken. Using the method, we measured 3.79ms (a bit over 1/2 a frame @144Hz) of input lag. The status of the ‘FreeSync’ (‘Adaptive Sync’) setting in the OSD made no measurable difference to this result and neither did activating the MBR (Motion Blur Reduction) feature. This value is influenced both by the element of input lag you ‘feel’ (signal delay) and the element you ‘see’ (pixel responsiveness). It indicates a low signal delay which shouldn’t bother even sensitive users. We don’t have the means to accurately measure input lag with Adaptive-Sync active in a variable refresh rate environment. Further observations were made using the animated TV series Futurama. This title has large areas of individual shade, making it a very unforgiving test for colour consistency. In this respect the monitor did relatively well, clearly identifying itself as an IPS-type panel. It was free from the sort of clear saturation shifts that occur at different sections of the screen for VA and moreover TN models. Some shades such as dark reds and medium blues appeared slightly deeper or duller towards the extreme side edges of the screen, from our preferred viewing position (eyes ~70cm from the screen). This becomes more pronounced if you’re sitting closer to the screen. It was not as pronounced as some of the TN or VA shifts you’d see from this sort of viewing distance, however. Shades appeared varied with distinct classes (pastel, deep, neon etc.) and excellent variety within each class. Saturation levels were again somewhat stronger than intended, but this was a universal increase in saturation. There were some excellent eye-catching neon pinks, purples and greens showcased and some impressive deep shades as well. This is again a sort of look many would find inviting, but it isn’t universally appreciated.

Other useful features include a low-blue light mode (with four different intensity presets), Frame Counter, Low Input Lag Mode, three gamma presets, three pre-calibrated picture presets (FPS, RTS, and Racing) as well as three fully customizable picture profiles. Design & Connectivity Quite a feature-rich OSD, good ergonomic flexibility, very slender top and side bezels and competitive pricing As above but even more effective. Blue light output is significantly reduced, more so if brightness is also lowered. For gamers on a tight budget, it’s the ideal gaming display that many have been waiting for. Image QualityMicrosoft for Business CouponExclusive: 20% off select Surface Pro 9 for Business + Type Cover Bundle Here’s the deal: when excess light passes through the panel, there is noticeable glowing around the corners of the screen. Contrast was also decent overall on Shadow of the Tomb Raider. This is a title where dimly lit interior locations, such as small passageways and caves are common. Often lit by a few point sources of light. As such, it looks its best where contrast performance is strong. Whilst the atmosphere the monitor created on this title wasn’t the same as on a VA model with stronger contrast, it was still respectable. The strong static contrast, for the panel type, and the ‘IPS glow’ being slightly more subdued than normal helped in this respect. But the ‘IPS glow’ is certainly still present and affects the dark regions of this title, if viewing in dimmer lighting conditions. There were no clear shifts in gamma as you’d get on VA models and to a greater extent TN models, though, so detail levels (‘IPS glow’ aside) were well-maintained. Brighter shades contrasted well with darker surroundings, whilst the screen surface imparted only a light misty graininess rather than anything more ‘smeary’ or obvious. Alternatively, you can use AMD FreeSync,which provides a variable refresh rate for compatible graphics cards to eliminate screen tearing and stuttering completely. And the good news? Gamers on a budget will finally be able to enjoy competitive FPS titles with excellent image quality, but without any prominent motion blur.

The object itself now appears with clear internal detailing, particularly for ‘MBR = 15’ and ‘MBR = 20’. Note that the white notches on the UFO body were actually a bit clearer in reality with ‘MBR = 15’ than they appear on the photos – the brightness levels caused them to appear a bit more blended than they should. This indicates excellent low perceived blur due to eye movement. There is pronounced strobe crosstalk behind the UFO (and also in front in the case of ‘MBR = 1’ and to a less extent ‘MBR = 15’), however. The reference shots don’t show this to the same degree, particularly for the S2417DG reference where overshoot is present but the shot is otherwise very ‘clean’ indeed with a very distinct main object. The image set below was taken with a further increase in refresh rate, to 144Hz with MBR active. Results here were variable, with significant deviations recorded towards the right side of the screen. The highest deviation was recorded towards the bottom right (DeltaE 4.3). 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. 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. Moving on, IPS monitors usually have a faster pixel response speed than VA panels, meaning that you won’t get noticeable smearing of dark pixels in fast-moving games. Another crucial thing to note regarding IPS panel displays is IPS glow,whichis an expected downside of this panel technology.As above with some gamma curve changes. The average gamma is now ‘2.1’, but the top and bottom of the curve (dark and light shades) sits above and mid-section (medium shades) below this. The overall changes to the image are reasonably subtle. There are two additional models with the ‘U’ suffix: the AOC 24G2U and the AOC 27G2U which feature a quad-USB 3.0 hub and integrated 2W speakers. These are not currently available in the US. You can also find the AOC 24G2E with a tilt-only stand.

Gamer Network Limited, Gateway House, 28 The Quadrant, Richmond, Surrey, TW9 1DN, United Kingdom, registered under company number 03882481. Although AOC doesn’t specify the gray-to-gray (GtG) response time speed of the 24G2 display, PANDA states a 7.5ms speed, which AOC managed to get down to ~5ms with the use of overdrive. Best of all, the AOC 24G2 is factory-calibrated at Delta E < 2, which is fit for entry-level color-critical tasks. For professional use, there are better color-critical displays, of course, but for basic content creation, the AOC 24G2 will do just fine. The AOC 24G2U's 144 Hz refresh rate, 1 ms MPRT and FreeSync support eliminate stuttering and tearing. Its 23.8" IPS panel with Full HD resolution delivers colour-accurate images. The full capability of the monitor including the 1920 x 1080 resolution, 144Hz refresh rate and Adaptive-Sync can be leveraged via either HDMI or DP. Note that Nvidia users with compatible systems can only use Adaptive-Sync (‘G-SYNC Compatible Mode’) via DisplayPort. Standard accessories include a power cable, DP cable and HDMI cable. This may vary regionally.The AOC 24G2U’s image quality is at a high level overall. The IPS panel has high color fidelity, good brightness, and a strong contrast ratio. In addition, the viewing angle dependency is quite low. This quality had a positive result when we tested it for gaming, as the neutral color and high contrast make the display appear realistic and three-dimensional. The 24G2U also goes one step further than the C24G1 when it comes to ports and inputs, too. You still get the same number of HDMI and DisplayPort connections as the C24G1, but the 24G2U has the all important addition of a 4-port USB3 hub, allowing you to hook up all your other peripherals such as your mouse, keyboard and USB headset as well as charge your phone. For me, that alone makes it worth the teensy bit of extra expense over the C24G1, which doesn't come with any USB ports whatsoever.
