The AOC AG273QCX HDR gaming monitor has an ergonomic stand with up to 110mm of height adjustment, +/- 30° swivel, -4°/22° tilt, and 75x75mm VESA mount compatibility, but no pivot/rotate function. The monitor had a range of ‘LowBlue Mode’ settings. These were fairly easy to access and vary in their effectiveness. The most effective mode, ‘Reading’, was not quite as strong in its blue light reduction as we’d like but was still fairly effective. It’s a setting which we used for our own viewing comfort in the evening but not for specific testing beyond the setting itself. More specifically, we used our ‘Test Settings’ with this applied over the top – you can make further manual adjustments to colour channels with a ‘LowBlue Mode’ active if you like, potentially making it more effective. Lowering brightness as well is very helpful in cutting blue light exposure. Cutting out blue light as much as possible in the hours leading up to sleep is useful as it’s an alertness signal used by the body to keep you awake and it disrupts sleep hormones.
The panel driving that gaming experience is VA with a native resolution of 2560x1440 and a maximum refresh rate of 144Hz. This is the “sweet spot” for modern high refresh rate gaming, offering a fluid, crisp gaming experience while not demanding most cutting edge hardware on the market. The display is also DisplayHDR 400 certified, though that comes with a big caveat. If your FPS drops below 48 FPS, the monitor uses Low Framerate Compensation (LFC) to maintain smoother performance by doubling or tripling the frame rate. Although the AOC AG273QCX is not officially certified as G-SYNC compatible by NVIDIA, you can still use FreeSync with GTX 10-series or newer GPUs. HDR content gets a boost in peak luminance (up to ~450-nits), which in addition to the wide color gamut (10-bit color depth is supported for HDR) and high contrast ratio, provides a noticeable upgrade in image quality.The images below are macro photographs taken on Notepad with ClearType disabled. The letters ‘PCM’ are typed out to help highlight any potential text rendering issues related to unusual subpixel structure, whilst the white space more clearly shows the actual subpixel layout alongside a rough indication of screen surface. This model uses a light matte anti-glare screen surface with a slightly rough surface texture. This offers good glare handling and preserves vibrancy better than some matte screen surfaces, whilst avoiding a heavy or ‘smeary’ graininess to the image or a layered effect of graininess. There is instead a light ‘misty’ graininess apparent when observing lighting content, so this doesn’t appear as smooth as on some screen surfaces (including the 31.5” variant of this panel as seen on the likes of the AOC AG322QCX). Most VA models, aside from those using this panel, are known to use smooth surface textures that are free from any readily observable graininess. So we would’ve preferred to have seen panel manufacturer Samsung employ a similar screen surface here. Gaming features include the Game Mode picture presets (FPS, RTS, Racing, and three ‘Gamer’ customizable profiles), Shadow Control and Game Control (color saturation and gamma curvature adjustments), Overdrive (Off, Weak, Medium, Strong), Dial Point (custom crosshair), Low Input Lag Mode, and Frame Counter. Fairly low input lag and a 144Hz refresh rate to give a good ‘connected feel’, and Adaptive-Sync working for both AMD and Nvidia users to get rid of tearing and stuttering from frame and refresh rate mismatches
The lighting brings nothing to the experience, and you'd be better off setting a specific color or just turning it off altogether. It's a shame since more manufacturers are now looking at ambient lighting, using in-game and on-screen content for showcasing color around the display. It's not a deal breaker, however. It’s a 27-inch flat gaming monitor with QHD resolution and to please the most avid gamers, has a 0.5ms response time, paired with a 240Hz refresh rate, made possible at this price because of the TN panel.Hư hỏng do thiên tai hoả hoạn, sử dụng nguồn điện không ổn định hoặc do vận chuyển không đúng quy cách.
As usual, if you’re running the monitor at 2560 x 1440 and viewing 1920 x 1080 content (for example a video over the internet or a Blu-ray, using movie software) then it is the GPU and software that handles the upscaling. That’s got nothing to do with the monitor itself – there is a little bit of softening to the image compared to viewing such content on a native Full HD monitor, but it’s not extreme and shouldn’t bother most users. As factory defaults with significantly higher gamma. Things now appear deeper and fuller with a vibrant and saturated look. The overall colour balance is good, with the white point just slightly higher than the target and no green tint. It’s also worth noting that the AG237QCX features one of the heaviest, most rugged stands I’ve ever encountered. Once it’s in place, it’s downright hard to move unless you use the handle built into the top behind the monitor. It’s height adjustable with a 110mm of range and features a +/- 30-degrees of swivel for sharing your screen with a neighbor. AOC AGON 3 AG273QCX Gaming Monitor – Testing and Gaming The monitor also includes a Dynamic Contrast setting called ‘DCR,’ but since there’s no local dimming, it’s not as effective as possible. It reacts well to changes in scene brightness but tends to be a bit too bright for mixed content. We prefer manual brightness control where local dimming is absent. Free-Sync and G-Sync Compatibility As ‘Gamma3’, but brightness set to a much more comfortable level and slight colour channel adjustments made. Image appears vibrant and strongly saturated, but varied and well-balanced in many respects.In case your FPS drops below 48FPS, LFC (Low Framerate Compensation) takes over and forces the monitor’s refresh rate to run at double or triple the frame rate for less tearing/stuttering.
for a monitor that sells itself on HDR, it turns out to be a much better gaming monitor with HDR disabled. The AOC AG273QCX also supports HDR (High Dynamic Range), and it’s certified by VESA as DisplayHDR 400. The gamma tests were a bit off, falling in the 2.3 range. Standard gamma calibration is 2.2, to these results are close but still slightly off. The gradient test was pristine, however, showing no banding whatsoever. The ghosting test also came out exceptionally well, which was borne out in my game tests where we observed no ghosting whatsoever.

Using the MBR option in the OSD (On-Screen Display) menu of the monitor, you can manually alter the strobing frequency (motion clarity vs picture brightness ratio). Features Since most games support only 8-bit color and the difference between 8-bit and 10-bit color in games is negligible, this is not a significant downside. The Lagom text appeared with red striping for the most part. This was somewhat more blended towards the top of the screen, with areas of a slightly darker red elsewhere. Around the edges there was a more distinct orange-red striping. There were shifts between various red tones and a more blended appearance alongside head movement changes. This indicates a moderate degree of viewing angle dependency to the gamma curve of the monitor, more so than IPS-type models but to a lesser extent than TN (and indeed some VA) models. The photo below gives a rough idea of how the Lagom text test appeared.
