About The Monitor

The Acer Nitro XV272UX is one of the most affordable 1440p 240Hz gaming monitors, yet it comes with a plethora of useful features that aren’t available in some of the more expensive models.

Image Quality

To start with, the Acer XV272UX monitor has a wide 99% Adobe RGB color gamut – that’s equivalent to ~160% sRGB!

You get even richer and more vibrant colors than what you’d get with a regular ‘wide gamut’ monitor. It excels at green and blue shades, so scenes with a lot of water, trees, and sky will look exceptionally beautiful.

Another very important thing is that the monitor has an sRGB emulation mode.

This gives you the ability to clamp the native ~160% sRGB gamut down to ~100% for a more accurate representation of sRGB content, which includes most games and general web content. Without it, you’d be stuck with over-saturated colors.

You can effortlessly switch between accurate sRGB color output and extra color vibrancy depending on your preference by simply toggling a setting in the OSD (On-Screen Display) menu.

The Acer XV272UX is also factory-calibrated at Delta E < 2, which in addition to its IPS panel’s wide viewing angles and excellent color consistency and accuracy – allows you to use the monitor for color-critical work.

Next, on 27″ sized screens, 1440p resolution hits the pixel density sweet spot as it provides you with plenty of screen space as well as sharp text and details, without any scaling necessary.

Further, the monitor has a peak brightness of 400-nits, which is plenty, while the contrast ratio is mediocre at 1,000:1, but this is expected from IPS monitors.

It also supports HDR (High Dynamic Range) with VESA’s DisplayHDR 400 certification, but due to its low contrast ratio and lack of local dimming, HDR content won’t look that much better. Some scenes might look a bit punchier due to the wide color gamut, but you shouldn’t be buying this monitor for HDR anyway; think of it as a bonus feature.

Features

Moving on, the Acer XV272UX has a rapid pixel response time speed, which efficiently prevents ghosting in fast-paced games.

However, due to the lack of variable overdrive, you’ll need to change the response time overdrive setting depending on your frame rate if you’re using a variable refresh rate (VRR), be it FreeSync with an AMD card or G-SYNC Compatible with a GeForce GPU.

If you’re running at 100FPS+, you can simply use the Normal overdrive mode up to 270FPS and over.

However, at lower frame rates (~60FPS), the Normal overdrive mode pushes the pixels too much, causing overshoot (or inverse ghosting). So, in those games, you’ll have to either dial down the overdrive to the ‘Off’ setting or disable VRR.

Both AMD’s FreeSync and NVIDIA’s G-SYNC Compatible technologies are supported and work without issues within the supported 48-240Hz range.

The monitor also supports Motion Blur Reduction (MBR) via the Visual Response Boost technology, which uses backlight strobing for CRT-like motion clarity.

It can’t be active at the same time as VRR and it decreases the maximum brightness while enabled, but it reduces perceived motion blur – something that will interest many FPS players. MBR also introduces flickering that’s invisible to the human eye, but might bother those sensitive to screen flicker after prolonged use.

Other useful features including Black Boost (improves visibility in darker scenes), a refresh rate tracker, custom crosshairs, and various pre-calibrated picture modes.

Design & Connectivity

Acer Nitro XV272UX Monitor

The Acer XV272UX has a fully-ergonomic stand with up to 120mm height adjustment, +/- 180° swivel, -5°/25° tilt, 90° pivot, and 100x100mm VESA mount compatibility.

Connectivity options include DisplayPort 1.4, two HDMI 2.0 ports (limited to 144Hz at 2560×1440), a headphone jack, two 2W built-in speakers, a quad-USB 3.0 hub, and a USB-C port with DP 1.4 Alt Mode and 65W Power Delivery.

The DisplayPort 1.4 input supports DSC 1.2 (Display Stream Compression), which allows for 1440p 270Hz with 10-bit color depth without any noticeable artifacts if you have a compatible GPU (AMD Navi, NVIDIA Turing, or newer).

Alternatives

  • Acer Predator XB273UGX – The same monitor but with a different design. It’s certified as ‘G-SYNC Compatible’, while the XV272UX is certified as ‘FreeSync Premium’ – but both models work with both AMD and NVIDIA cards.

The Pros:

  • Wide Adobe RGB color gamut
  • Plenty of features including a native G-SYNC module for flawless VRR performance
  • Fully ergonomic stand and a USB hub

The Cons:

  • No DSC and MBR technology
  • IPS glow and inferior contrast ratio to VA panels, as expected from this panel technology

About The Monitor

If you want a 1440p 240Hz gaming monitor with a dedicated G-SYNC module, we recommend the ASUS ROG Swift PG279QM.

Image Quality

In terms of image quality, the PG279QM is very similar to the XV272UX. You get the same wide 99% Adobe RGB color gamut, a 1,000:1 contrast ratio, and DisplayHDR 400.

However, the PG279QM offers a slightly higher peak brightness of ~550-nits and 16 local dimming zones.

These zones can dim parts of the screen that should be dark, but since there are only 16 zones, you will only see benefits of this when dark and bright objects are far apart.

Due to this, the HDR image quality is a bit better in comparison to the XV272UX, though not good enough to buy this monitor solely for HDR content.

Since the DisplayPort 1.4 input on the PG279QM doesn’t support DSC 1.2, you will be limited to 144Hz with 10-bit color depth and full RGB color range.

For over 144Hz, you will need to drop the color depth to 8-bit or use chroma subsampling. Since most games and content in general are 8-bit color, this won’t be a big issue for most users.

You will most likely notice the difference between 8-bit and 10-bit color when looking at gradients, for instance, in Photoshop or HDR content.

However, HDR is not one of the reasons you should be considering the monitor anyway, and if you really need slightly smoother gradients while working on a photo/video, you can drop the refresh rate to 144Hz.

Also, note that the PG279QM uses the sRGB color gamut for accurate (DeltaE < 2) color output out of the box. To get more saturated colors, just enable the Wide Color Gamut option in the OSD menu.

Features

g sync compatible vs native g sync

The G-SYNC module of the ASUS PG279QM offers a wider VRR range of 30-240Hz in comparison to the XV272UX, as well as variable overdrive support, which ensures that there’s no ghosting at high frame rates and no overshoot at low frame rates!

So, you won’t have to change the overdrive mode depending on your frame rate when using a variable refresh rate. However, you won’t be able to overclock the monitor to 270Hz (unless you try it manually) or use backlight strobing as the PG279QM doesn’t support it.

The ASUS PG279QM also supports NVIDIA Reflex Latency Analyzer, which allows you to measure the latency between the monitor and your commands if you have a compatible gaming mouse.

Other features include Dark Boost, on-screen timers and crosshairs, a refresh rate tracker, various picture presets, and AuraSync RGB lighting at the rear of the monitor.

Design & Connectivity

The monitor features an ergonomic stand with up to 100mm height adjustment, 90° pivot, -5°/20° tilt, +/- 25° swivel, and 100x100mm VESA mount compatibility.

Connectivity options include DisplayPort 1.4, three HDMI 2.0 ports (limited to 144Hz), a headphone jack, dual 2W integrated speakers, and a dual-USB 3.0 hub.

Alternatives

Another 1440p 240Hz IPS gaming monitor with a dedicated G-SYNC module worth mentioned is the Dell Alienware AW2721D.

However, it doesn’t have an sRGB mode, so all sRGB content will be over-saturated. It also doesn’t have as wide Adobe RGB color gamut.

While it has DisplayHDR 600, it’s only slightly brighter and has only several additional dimming zones, so its HDR image quality is still not that good.

The Pros:

  • High native contrast ratio for deep blacks, wide color gamut
  • Plenty of features including FreeSync and MBR up to 240Hz
  • Fully ergonomic stand and rich connectivity options, including DP with DSC and a USB hub

The Cons:

  • The 1000R screen curvature might be too aggressive for some users
  • Some users report micro-stuttering issue with VRR enabled

About The Monitor

Want a 1440p 240Hz gaming monitor with a VA panel for deep blacks? Check out the Samsung Odyssey G7 with a 1000R curved screen.

Image Quality

The Samsung G7 is available in both 27″ and 32″ screen sizes, but they share all the other specifications: the Samsung C27G75T and the Samsung C32G75T.

Since both models have 1440p resolution, the image will be sharper on the 27″ sized model due to the higher pixel density, whereas the 32″ variant has the same pixel per inch ratio as a 24″ 1080p monitor, but has a more immersive viewing experience due to its larger screen.

The VA panels of these 1440p 240Hz gaming monitors have a high contrast ratio of 2,500:1, which results in inky blacks and more vivid details in shadows.

Further, VA monitors don’t suffer from IPS glow, so dark scenes generally appear more engaging, especially in dark or dim-lit rooms.

With a 95% DCI-P3 color gamut (~125% sRGB), the colors aren’t as saturated as that of the previous two IPS monitors with Adobe RGB gamut, but they are still rich and vibrant – plus, the higher contrast ratio makes up for it.

The Odyssey G7 monitors also support DisplayHDR 600, though there are only 8 dimming zones.

While the image quality is generally more immersive on VA panels, the viewing angles aren’t as wide and there are some contrast/gamma shifts at certain angles.

For everyday use and gaming, it’s not bothersome. In fact, you can do some basic content creation too, but if you’re serious about color-critical work, you’ll need to go the IPS route for better consistency.

Another thing that might repel some users is the aggressive 1000R screen curvature. Some people despise it, some love it, and some don’t really care for it. It does take some time getting used to, but people mostly prefer flat-screen panels at this screen size/aspect ratio.

Features

The Samsung Odyssey G7 1440p 240Hz gaming monitors were the first VA panel displays with a fast 1ms GtG pixel response time speed.

There’s no visible ghosting or pixel overshoot regardless of your refresh rate and you also get the MBR backlight strobing technology for less motion blur.

Both AMD’s FreeSync and NVIDIA’s G-SYNC Compatible technologies are supported for tear-free gameplay.

If you experience brightness flickering with a variable refresh rate, you’ll need to make sure you have to latest monitor firmware installed and enable the ‘VRR Control’ option in the OSD menu to prevent this issue.

However, some users experience micro-stuttering with this option enabled, so if you want a guaranteed flawless VRR performance, IPS monitors are your best bet.

The intensity of micro-stuttering seems to vary across different units and not all gamers are equally sensitive to it, but since screen tearing is hardly noticeable at 240Hz, some users will just play with VRR disabled.

Other features include Black Equalizer, custom crosshairs, various picture presets, Picture in Picture/Picture by Picture, and RGB lighting at the back and front of the monitor.

Design & Connectivity

The Samsung G7 offers an ergonomic stand with up to 120mm height adjustment, -9°/13° tilt, 90° pivot, +/- 15° swivel, and 100x100mm VESA mount compatibility.

Connectivity options include two DisplayPort 1.4 inputs with DSC 1.2, an HDMI 2.0 port (limited to 144Hz), a headphone jack, and a dual-USB 3.0 hub.

Alternatives

  • AOC AGON PD27 (Porsche Design) – a 27″ 1440p 240Hz 1000R curved gaming monitor based on the same (or similar) panel as the C27G75T. However, it has DisplayHDR 400 only and its overdrive is not as good as there’s more overshoot; you have to swap between the Medium and Strong overdrive modes depending on your frame rate.

The Pros:

  • Wide Adobe RGB color gamut
  • Plenty of features including 270Hz OC
  • Ergonomic stand and rich connectivity options including DP with DSC and a USB hub

The Cons:

  • Minor overshoot at low frame rates when using VRR
  • IPS glow and inferior contrast ratio to VA panels, as expected from this panel technology

About The Monitor

The Acer Predator XB323UGX is essentially the 32″ version of the XB273UGX/XV272UX models we’ve mentioned earlier.

Image Quality

You get that same wide 99% Adobe RGB color gamut (with an sRGB mode), 1,000:1 contrast ratio, Delta E < 2 factory calibration, fast 1ms GtG response time, wide viewing angles, and 270Hz factory-overclock.

Additionally, the XB323UGX offers a better HDR viewing experience with VESA’s DisplayHDR 600 certification, which implies a higher 600-nit peak brightness and local dimming, though with only 16 zones.

So, as with all 1440p 240Hz monitors, some HDR content will look a bit better, some will look the same, and some might even look worse, depending on how demanding the scene is. HDR shouldn’t be a priority when buying these displays, so think of it as an extra feature.

Features

Features and performance are pretty much the same as that of the 27″ variants. You get a fast response time speed, though you might need to dial back the overdrive at lower frame rates if you’re using variable refresh rate to prevent overshoot.

Both AMD’s FreeSync and NVIDIA’s G-SYNC Compatible technologies are supported with a 48-240Hz VRR range. So, if you choose to overclock the monitor to 270Hz, you won’t be able to use VRR.

Alas, the XB323UGX does not support backlight strobing/Visual Response Boost.

Other gaming features are available, such as Black Boost, refresh rate tracker, custom crosshairs, and various picture presets.

Design & Connectivity

Acer Predator XB323UGX Monitor Back

The stand of the monitor offers height adjustment up to 130mm, tilt by -5°/23°, +/- 20° swivel, and 100x100mm VESA mount compatibility.

Connectivity options include DisplayPort 1.4 (with DSC 1.2), two HDMI 2.0 ports (limited to 144Hz), a headphone jack, and a dual-USB 3.0 hub.
