The OLED worth wars are right here.
Acer’s Predator X27U X1 is a brand new monitor with a 27-inch 1440p QD-OLED show. Yet it carries an MSRP of $600, which is a whole bunch of {dollars} lower than the MSRP comparable screens had in 2023 and 2024. Acer is compelled to make just a few compromises to hit a low worth however, in relation to picture high quality, the X27U X1 is a match for its friends.
Read on to be taught extra, then see our roundup of the best gaming monitors for comparability.
Acer Predator X27U X1 (X1bmiiphx) specs and options
The Acer Predator X27U X1’s specs are typical for a 27-inch QD-OLED monitor. It has a 26.5-inch QD-OLED panel with 2560×1440 decision and a refresh fee as much as 240Hz. Adaptive sync is supported, although solely AMD FreeSync Premium Pro is formally listed.
- Display dimension: 26.5-inch 16:9 widescreen
- Native decision: 2560×1440
- Panel sort: 10-bit OLED
- Refresh fee: 240Hz

- Audio: 2x 5-watt audio system
- Warranty: 3 years
- Price: $599.99 MSRP, as little as $449.99 retail (U.S.)
Pricing is the place the Predator X27U X1 stands out, because it lists an MSRP only one cent shy of $600. Most comparable screens record an MSRP of $799.99 or extra. Newegg already lists this monitor at $450.
Shoppers needs to be cautious to write down down the X27U X1’s full mannequin identify, which is X1bmiiphx (sure, actually). Acer sells a number of screens which might be comparable in identify, design, and specs. It’s complicated sufficient that, as of March 2025, Newegg has the incorrect images on its itemizing for this monitor.
Acer Predator X27U X1 design
The Acer Predator X27U X1 is clearly designed, constructed, and priced with affordability in thoughts. That results in fewer compromises than I anticipated, however its design displays the value. Though it does have a tiny Predator badge on the underside bezel, the monitor is in any other case extremely generic. It’s constructed from sturdy however unremarkable black plastics and lacks thrives like customizable RGB-LED accent lighting.
I’m not a fan of the stand, both. While the monitor itself is generic, the stand feels a bit low cost. This is usually as a result of coarse texture of the supplies used. The tiny plastic clip used for cable administration, which feels prefer it’s positive to interrupt after a few years, doesn’t assist issues. I don’t just like the design of the stand base, both. It’s wider than most but doesn’t maintain the monitor any extra steady than its competitors.

With that mentioned, although, Acer’s funds stand retains a lot of the performance you’d anticipate from a dearer OLED monitor. It adjusts for peak, tilt, and swivel, although it doesn’t pivot into portrait orientation. A 75x75mm VESA mount is accessible to be used with third-party monitor stands and arms.
Acer Predator X27U X1 connectivity
Acer retains the Predator X27U X1’s connectivity so simple as its design. The monitor has two HDMI 2.1 ports and one DisplayPort 1.4. All video ports can deal with the monitor’s full decision and refresh fee. The monitor additionally has a 3.5mm audio-out.
But that’s it for connectivity. It has no USB-A or USB-C ports, which additionally means it lacks a KVM change operate (an more and more widespread function on OLED screens).
The lack of USB is definitely a draw back and makes the Predator X27U X1 much less versatile than dearer alternate options. Alternatives just like the MSI MPG 272URX provide a number of USB ports and USB-C with Power Delivery. That monitor has an MSRP of $1099.99, nonetheless.
Acer Predator X27U X1 menu and options
The inexpensive Acer Predator X27U X1 makes cuts to design and connectivity, however that’s the place the sacrifices finish.
Contrary to what the value suggests, the X27U X1 has an efficient on-screen menu with many choices. While I do take situation with the font dimension, which is a bit small and low distinction for my tastes, I used to be shocked by the plethora of choices. In specific, the monitor has easy-to-find settings for colour temperature, gamma, and six-axis colour calibration.

The monitor additionally consists of gaming options, like a darkish equalizer (which may elevate shadowy areas of a scene to make foes seen) and a body fee counter. The monitor consists of a number of display screen house modes, too. For instance, you possibly can prohibit the seen space to 24 or 22 inches if desired.
Acer packs the show with a pair of 5-watt audio system (most OLED screens haven’t any audio system or follow dinky 2-watt audio system). The audio system aren’t going to knock your socks off, however they’re loud and clear. I didn’t thoughts counting on them for watching YouTube or enjoying video games that don’t deal with bombastic audio design (like Civilization), they usually’re indisputably an improve over best screens.
It’s unimaginable to see this degree of colour efficiency from a monitor bought on-line for as little as $449.99.
Acer Predator X27U X1 SDR picture high quality
The Acer Predator X27U X1’s affordability isn’t apparent from its picture high quality. It has a 26.5-inch QD-OLED panel with a local decision of 2560×1440. It has all the advantages widespread to OLED panels and doesn’t undergo any important flaw.
Matthew Smith / Foundry
Let’s get the dangerous information out of the best way. The Acer Predator X27U X1, like different OLED screens, has a comparatively tame most SDR brightness of 263 nits. That’s typical for an OLED monitor however a great distance from the brightest LCD-IPS screens, which may exceed 400 nits.
This received’t matter in most conditions, as a brightness of 200 nits or extra is sufficient for a typical house workplace or gaming den. If you propose to make use of the monitor in a brightly lit room the place you possibly can’t flip off or block close by mild sources, nonetheless, you may discover the brightness unimpressive.
Matthew Smith / Foundry
Contrast, as typical for OLED, is great. The QD-OLED panel can obtain a minimal brightness of zero nits, which lets the monitor ship a convincing sense of depth and dimensionality. Brighter scenes will appear to have depth inside the scene, whereas darker scenes will present shadow particulars and a real, deep black degree that backlit LCD shows can’t present.
Matthew Smith / Foundry
Color gamut is a energy of all OLED screens, however the Acer Predator X27U X1 knocks it out of the park. It confirmed as much as 100 % of sRGB, 98 % of DCI-P3, and 95 % of AdobeRGB. That’s the widest colour gamut of all of the OLED screens I’ve examined to date in 2025, although solely by a hair.
A large colour gamut interprets to a vivid, saturated picture that appears punchy straight out of the field. It’s additionally excellent news for creatives who need to work with images, movies, or digital artwork that targets a selected colour gamut. Despite its worth, the X27U X1’s colour gamut is on par with many shows pitched at inventive professionals.
Matthew Smith / Foundry
The Acer Predator X27U X1 scores properly in colour accuracy, too. It’s not the perfect, however not the worst, and the extent of colour accuracy offered right here is sufficient that even essentially the most crucial viewers needs to be proud of the outcomes. Content appears reasonable and true to its authentic inventive intent.
The monitor scored barely off-target in gamma and colour temperature. It hit a gamma curve of two.3 (off a goal of two.2) and a colour temperature of 6400Okay (off a goal of 6500). I discovered the distinction in gamma noticeable, as content material typically seemed a bit of darker than ultimate, however I struggled to note the distinction in colour temperature. Also, most QD-OLED screens have an identical gamma curve. In each circumstances the variations are minor.
Sharpness is the Predator X27U X1’s solely actual image-quality flaw. A decision of 2560×1440 just isn’t that sharp in 2025, and it’s made worse by the sub-pixel points QD-OLED shows can undergo. You could discover robust pixelation or colour artifacts round small fonts and high-contrast edges. This isn’t typically noticeable in video games, but it surely’s straightforward to identify in Excel spreadsheets or an IDE like VSCode. Put merely, I wouldn’t advocate the X27U X1 if you happen to typically view small textual content in your monitor—a 4K OLED, or an IPS-LCD show, will likely be higher for that process.
The Acer Predator X27U X1’s SDR picture high quality is great and precisely in keeping with most OLED screens, together with many which might be dearer. It scores particularly properly in distinction, colour gamut, and colour accuracy, the place the X27U X1 delivers outcomes on par with the most costly OLED shows obtainable immediately. It’s unimaginable to see this degree of colour efficiency from a monitor bought on-line for as little as $449.99.
Acer Predator X27U X1 HDR picture high quality
Okay, so the inexpensive Acer Predator X27U X1 delivers SDR picture high quality on par with different 1440p QD-OLED screens, regardless of their worth. So, absolutely, it should quit some HDR efficiency—proper?
Matthew Smith / Foundry
Nope. It’s a strong HDR monitor.
Yes, the Predator X27U X1 turned in outcomes which might be technically a bit dimmer than another OLED screens I’ve lately examined.
But these are slightly slim variations and, as I check increasingly more OLED screens, I’ve grow to be satisfied that the type of variations proven within the graph don’t translate to a significant real-world benefit. That’s to not say HDR brightness doesn’t matter, however I don’t suppose the good thing about a barely brighter HDR monitor, just like the Alienware AW2725Q, is simple to see.
The check clips that I usually view, which embody the “Into the Storm” scene from Mad Max Fury Road and the “Gargantua” scene from Interstellar, confirmed good luminance element and impactful HDR highlights. HDR video games like Forza Horizon 5 seemed nice, too, offering a vivid and punchy presentation.
Acer Predator X27U X1 movement efficiency
You received’t see any compromise within the monitor’s movement readability, both.
The Acer Predator X27U X1, like most 1440p OLED screens, has a most refresh fee of 240Hz and quotes gray-to-gray pixel response instances as little as 0.03 milliseconds. This makes for wonderful movement readability with minimal ghosting.
Test pictures from League of Legends, for instance, confirmed that character names and hitpoint bars had been often straightforward to learn whereas scrolling throughout the map, although low-contrast font can nonetheless be onerous to make out. A fast digital camera pan in a 3D sport, like Valorant, will present good element even in small objects. The movement readability is useful in Word and in internet browsers, too, as fonts are simpler to learn when scrolling down a web page or doc.
Of course, the identical is true of different OLED screens with a 240Hz refresh fee. But it’s good to see the X27U X1’s cheaper price doesn’t compromise movement readability.
Adaptive sync is supported, however Acer solely lists official help for AMD FreeSync Premium Pro. The monitor will usually work with G-Sync and different video sources that help adaptive sync, but it surely’s not assured. This is one small compromise within the identify of affordability, as dearer screens typically record themselves as appropriate with each FreeSync and G-Sync.
Should you purchase the Acer Predator X27U X1?
The Acer Predator X27U X1 is proof that 2025 is the 12 months OLED turns into inexpensive. At $600 MSRP, which is already discounted to as little as $450 on-line, the X27U X1’s pricing severely undercuts what was typical for OLED screens in 2024. It additionally begins to compete with high-end IPS-LCD screens which, although they nonetheless have just a few perks (like sharpness), usually can’t compete with OLED on picture high quality.
I anticipate that Acer’s opponents received’t hesitate to match the X27U X1 with their very own worth cuts. But, for now, the X27U X1 is an effective alternative if you wish to get pleasure from OLED for much less.
