What the 240Hz refresh rate gives you
A 240Hz screen can refresh up to 240 times each second, but the benefit depends on the game, your PC’s frame rate, and your sensitivity to motion. At 240Hz, one refresh interval is about 4.17ms, compared with 6.94ms at 144Hz and 16.67ms at 60Hz. The jump from 60Hz to 144Hz is usually more striking than the step from 144Hz to 240Hz.

For fast competitive games, a high and consistent frame rate can make movement look smoother and provide more frequent visual updates. To make full use of 240Hz, a PC needs to produce very high frame rates—ideally approaching the display’s ceiling in the games you play. A CPU-limited title, demanding graphics settings, or a system that regularly runs well below 144 frames per second will leave much of the monitor’s speed unused. The 1080p resolution helps reduce GPU load compared with 1440p, which is part of the XB272’s esports-focused trade-off.
How the 27-inch 1080p picture holds up
At 27 inches, Full HD works out to roughly 81.6 pixels per inch. That is visibly less dense than 1080p at 24–24.5 inches, which is around 90–90.5 PPI, or 1440p at 27 inches, around 108.8 PPI. Text, fine interface details, and thin lines can look softer on the XB272; pixels may be more noticeable at ordinary desktop distance. It is not unusable, but the compromise is easier to accept when competitive frame rate matters more than desktop sharpness.
TN strengths and compromises
The TN panel supports the monitor’s speed-oriented purpose, but its image is less stable off-axis than a typical IPS screen. Acer specifies a 1,000:1 contrast ratio and 170° horizontal/160° vertical viewing angles; those angle figures do not mean that color and brightness remain uniform from every position. On a 27-inch screen, the top and bottom are viewed at different angles, so shifts in brightness or color can be noticeable. It is also a less appealing choice for movies, photo work, or other tasks where consistent color and viewing angles matter.

- Resolution Matters: This 24.5” FHD (1820 x 1080) display packs a fierce punch. Immerse yourself in the hyper-realistic colors of the game world. Smooth transitions, finer shades and uniform appearance are achieved with 99% sRGB.
- AMD FreeSync Premium Technology: Say “goodbye” to stuttering and tearing. With AMD FreeSync Premium, the monitor’s frames are synced with the graphics card’s frames, which eliminates screen tearing and provide the smoothest gaming experience.
- Up to 300Hz Refresh Rate: The 300Hz refresh rate speeds up the frames per second to deliver an ultra-smooth 2D motion scene. With a rapid refresh rate of 300Hz, Predator Monitors shorten the time it takes for frame rendering, lower input lag and provide gamers an excellent in-game experience.
- Goodbye Ghosting: Fast response time of 1ms enhanced gamers’ in-game experience. No matter the fast-moving action or any dramatic transitions will be all rendered smoothly without the annoying effects of smearing or ghosting.
- Be Flexible: The ErgoStand design provides freedom to swivel, pivot and adjust height for maximum adaptability and comfort, while Acer VisionCare helps protect eyes during long gaming sessions.
Color, brightness, and HDR
Acer lists 400-nit brightness and 16.7 million colors, but those figures do not establish strong HDR performance. The product is not presented as a modern DisplayHDR-certified monitor, and its TN panel and listed 1,000:1 contrast do not provide the deep blacks or highlight control that make HDR compelling. Treat the XB272 as an SDR gaming display; HDR should not be a reason to buy it. Its color may be serviceable for everyday use, but this is not a color-critical display.

G-SYNC, response time, and ULMB
The XB272 belongs to the original hardware G-SYNC generation. Variable refresh can synchronize the display with the GPU’s output within the supported operating range, helping reduce tearing and stutter when frame rate fluctuates. It does not generate frames or make a slow system perform like a 240-fps system. This original G-SYNC implementation is distinct from the later “G-SYNC Compatible” category associated with Adaptive-Sync displays.
Acer’s “1ms” response-time figure is a specification, not a guarantee that every pixel transition completes in 1ms. Motion clarity also depends on refresh rate, frame rate, pixel transitions, overdrive tuning, and sample-and-hold blur. Tom’s Hardware tested the related 24.5-inch XB252Q—not the 27-inch XB272—and found that its most aggressive overdrive setting could create black-line artifacts around moving objects, while Normal avoided that problem. Treat that as family context, not a direct XB272 measurement: Tom’s Hardware XB252Q testing.

- OLED Makes All The Difference: With a display of these mammoth-like proportions, everything must look good. The WQHD quantum dot OLED display with true 10Bit is obligated to offer stunning contrast, cinematic color. Image retention-refresh keeps the images from sticking.
- Tear-Free Frames: Get in the game with the AMD FreeSync Premium Pro/Nvidia G-Sync Compatible display. Each display is validated by AMD to bring you a smooth, variable refresh rate (VRR) gaming experience that eliminates tearing, stuttering, artifacts, and flicker.
- Fast and Furious: If you want seamless gameplay at ridiculous levels of speed, you’ve come to the right place. With a 500Hz refresh rate and 0.03ms (G to G) response time, your sessions will be fluid, unbroken and unmatched – with little to no ghosting
- Brilliant Colors: Boasting a DCI-P3 99% color gamut, Delta E<2 and VESA DisplayHDR True Black 500, vibrant colors leap from the screen. Revel in the finest visuals your games can deliver!
- Center of Vision: At 26.5-inches, the X27U is directly in your field of view. Considered a hallmark of eSports tournaments, this is the perfect size to gain an edge over your opponents. The addition of a ZeroFrame design also removes the bezels – giving you have even more visibly over every match and every movement your rivals make.
The XB272 generation also supports NVIDIA ULMB, a backlight-strobing mode intended to improve perceived motion clarity. ULMB can reduce brightness and generally conflicts with variable-refresh operation, so it is a choice rather than an upgrade to use alongside G-SYNC. It is most relevant for stable, high-refresh gameplay; for variable frame rates, G-SYNC is usually the more useful mode. Acer’s original feature information is covered in Tom’s Hardware’s XB272 announcement.
Design, stand, and connectivity
The adjustable stand is a practical plus for an older gaming monitor: Acer lists height adjustment of about 4.53 inches, tilt from approximately -5° to 20°, swivel, and VESA mounting support. It also lists DisplayPort, HDMI, USB connectivity, and two stereo speakers. The built-in speakers are convenient for basic sound, not a substitute for dedicated gaming audio. Check Acer’s product listing and the particular unit before relying on exact port count or included accessories.
For a used purchase, confirm whether the original stand, power supply, and any cables you need are included. A monitor with an intact panel but missing stand hardware or power accessories may be less of a bargain than its listing price suggests.

How to set up 240Hz and G-SYNC
- Connect the PC to the monitor directly. Use DisplayPort where possible and connect to the discrete graphics card rather than a motherboard output. Avoid assuming a dock, KVM, receiver, adapter, or arbitrary cable will pass the full operating mode.
- Install a compatible NVIDIA driver. Make sure the graphics driver is installed and current for your GPU and operating system.
- Select the display and refresh rate in Windows. Open Settings > System > Display, select the XB272, then open Advanced display and choose 240Hz if available. Menu wording can vary by Windows version.
- Enable G-SYNC in NVIDIA Control Panel. If the monitor is detected, open NVIDIA Control Panel and check the G-SYNC setup options. Enable the applicable setting for the display and confirm the configuration.
- Verify before playing. Check the refresh rate shown in Windows or NVIDIA Control Panel, then confirm operation in a game or refresh-rate utility. Acer provides model support and downloads at its XB272 support page.
If 240Hz or G-SYNC is missing
- Only 60Hz or 144Hz is offered: Check that Windows is set to the intended refresh rate, the correct monitor input is selected, the driver is installed, and the connection is direct. Try a suitable DisplayPort cable and remove intermediary devices while troubleshooting.
- G-SYNC does not appear: Check the DisplayPort connection, NVIDIA driver, selected display in Control Panel, and the monitor’s relevant adaptive-sync/G-SYNC setting. An intermediary device can also interfere with detection; GPU support and configuration matter.
- Motion looks worse at 240Hz: Try a less aggressive overdrive setting, verify the actual refresh rate and in-game frame rate, and do not combine ULMB and G-SYNC as though they were a single mode. Ordinary sample-and-hold blur can remain even at 240Hz.
- The image looks washed out or uneven: Check brightness, RGB range, and color settings, but remember that TN viewing-angle shifts are a panel characteristic rather than necessarily a defect.
XB272 versus a newer monitor
The XB272’s case is strongest when the buyer specifically wants high-frame-rate 1080p esports and finds a working unit cheaply. For a current new monitor, Acer’s catalog includes 27-inch WQHD options, including the Nitro VG272U W3BMIIPX, listed at 2,560 × 1,440 and 240Hz with IPS-oriented positioning. Its higher resolution should suit both gaming and desktop work better, though the XB272’s lower pixel count can be easier to drive at very high frame rates. Acer’s Nitro VG2 series page describes a broader range, so specifications vary by model.
A 24–25-inch 1080p high-refresh display is another sensible direction for a player who prioritizes esports but wants denser pixels than the XB272 offers. A 27-inch 1440p high-refresh IPS screen is the stronger all-round choice for mixed gaming and desktop use. OLED is a separate image-quality option for buyers prioritizing contrast and response characteristics, but the XB272’s relevant comparison is not a blanket win for any panel type: price, intended use, and specific model matter.
Do not confuse the XB272 with the 24.5-inch XB252Q, the XB272Q variants, the 27-inch 1440p IPS XB271HU, or newer XB273U models. Tom’s Hardware described the XB252Q and XB272 as similar in their 1080p/240Hz/TN/G-SYNC positioning, but testing of the XB252Q is not direct testing of the XB272: Tom’s Hardware’s model announcement.

Acer’s U.S. listing showed $599.99 and out-of-stock status when checked in August 2026; that is a listed price and availability signal, not a current used-market price. No verified used price is established here, so compare the asking price yourself with current 1440p high-refresh alternatives rather than treating the old list price as a fair-value benchmark. The recommendation to buy only at a substantial discount is a judgment based on the monitor’s age, resolution, panel type, and current alternatives.
Quick Recap
- Confirm the model label says XB272 or XB272 BMIPRZ, not XB252Q, XB272Q, or another Predator model.
- Inspect for dead or stuck pixels, scratches, coating damage, uneven backlight, and severe bleed.
- Test 240Hz over DisplayPort and check whether G-SYNC is detected by the intended PC.
- Check for flicker at 240Hz, and verify the OSD and power controls work.
- Test USB ports and speakers if you expect to use them.
- Check that the stand is complete and undamaged, and confirm VESA hardware and accessories needed for your setup.
- Agree on a return option or test period where possible; a seller’s claim that the display “works” may not confirm its high-refresh mode.
Who should buy the Acer Predator XB272?
Consider it if
- You mainly play competitive shooters or other fast esports titles.
- Your PC can sustain roughly 200–240 fps in your games at 1080p.
- You value refresh rate and low-latency play more than sharpness, HDR, or color consistency.
- You find a tested unit at a substantial discount and accept the compromises of 27-inch 1080p TN.
Look elsewhere if
- You want crisp text, detailed single-player visuals, or a versatile work-and-play screen.
- You need HDR, wide-gamut color, or a display for editing and color-critical work.
- Your system rarely exceeds 144 fps, so the 240Hz ceiling is unlikely to matter much.
- You need modern laptop features such as USB-C video and power delivery, or prefer a new product with straightforward warranty and replacement availability.
- The asking price approaches Acer’s historical $599.99 U.S. listing.
