There was a problem filtering reviews right now. Please try again later.
The only issue really, being the price tag. It is rather high, being only a 1920x1080 monitor, however that Alienware for you! Still would recommend, maybe try and wait for a sale or discount!

All 3 monitors were tried and tested on 2 different PCs, on Win7 with a GTX1080 and the other PC was Win10 with a GTX1660ti. Both Display Port and HDMI were used and the issue occurred using both, RGB Full Range and YCbCr Limited were tested. I don't think the issue might be able to happen with RGB Limited but then you get washed out colours.
The first major issue with the monitor is image retention, the first image is the image retention and 3rd is a video of the issue. This issue happened across all 3 monitors, some combination of colours can cause the issue to happen, I normally had it while web browsing but also had it once when opening a game. The issue seems to mainly occur when theres lots of shades of grey and might be fixable with a firmware issue. The retained image does fade away slowly over time however a image up for 30 seconds which cause it will persist for 10 minutes up to an hour.
Note: The Acer XB253QGX had the issue with a different image but it had a lot of darks/lights greys.
2nd is a nitpick and slightly harder to see, there is no image retention from the issue but on the purple square where there is the "\/\/\/\/\/\/\/\/" pattern, that pattern will expand on that entire row (note the monitor is running in RGB mode not YCbcr for this image) and would even draw on top of the OSD. Its only visible on greys, whites/black/varies solid colours while its there its a lot less noticable more hidden away but its again a defect that shouldn't happen. This issue even happens when in RGB Limited Range however for some reason when the monitor is ran in 60hz the problem is not always there.
The huge faults aside which seem to impact all 1st Generation 240hz IPS 25" Monitors, it is a good monitor, it is G-Sync compatible and works well along side overdrive. On overdrive I would recommend the faster option, it does have some overshoot but its so minor you'd probably not notice and reduces blur a lot more than the default "fast", I wouldn't touch the extreme overdrive option at all. The Alienware doesn't have the best colour accuracy and contrast ratio out of the box (The Acer Predator was amazing but it has its own weird faults and quirks) however when calibrated its amazing, I recommend having the contrast set to 80 in the monitor to get the best ratio from it.
If you don't mind randomly getting image retention which in all honestly it is rare to happen but it does happen then its a good monitor but for similar priced 240hz IPS you get more features from Acer/Asus which have black frame insertion for example.
Me personally, I can't look past the huge flaws/defects, they might be able to firmware update to fix them but for now I am returning all 3 for refunds.
What can I say?? Absolutely superb. Nice metal finish with a few plastic bits like the wiring tunnel and cover.
At 240hz where can you complain? Games are silky smooth. No jittering no nothing. Presets are okay? The “gaming” Preset is as useful as a canopener on a car tyre. Washed out the display to the point I was scratching my eyes out. Apartment from the presets everything is tip-top.
For FHD it’s really good picture quality. Everything is crystal clear. Obviously not as sharp as an oled but the brightness makes up for it. Ever woken up and some random light burns your eyes out? Yeah it’s that bright. Another nice tough is the Bezzless design. I hate the fat chunky design of some monitors but this tops the cake for design. Sleek and easy. wouldn’t have hurt them to make this a 1440p monitor for the price point but meh that’s just me being picky.
THE BOX IS HUGE! make sure you evacuate your house hold before bringing this monster into your living area.
This has RGB lighting which is amazing. Dim your lights and watch the spectrum happen. Also it’s has tilt and adjusting features if your into the malarkey
I’d recommend this for people who want response over picture quality. Picture quality is good but wish it was a 1440p version because of the price. 25’ is small to me but make sure you have enough room. 2 HDMI Ports 3 USB 3.0 ports and / DP ports.
Any questions be sure to ask
The first screen was decent - quality was pretty good, packaging was okay but not G-SYNC compatible. The ASUS screen was pretty much identical but it did have a better resolution and was G-SYNC compatible, but the overall build quality just wasn't great. There were gaps between the screen and the case, and backlight bleed at the bottom of the screen. Also, I had a dead pixel in the middle of the screen which was the main reason for getting rid of this monitor. ASUS allow up to 4 brigh dead pixels before saying a monitor is faulty, alienware/dell allow zero, so that gives you an idea of the QA which you get with this monitor.
Then this screen arrives...
First of all the packaging is amazing. Very well thought through, easy to unpack with good instructions. It just feels and looks like a quality product out of the box.
The screen itself is much brighter and clearer than I thought it would be, and even at 1080p looks really crisp at 25". The stand is as good as expected, and the cable management system provided works really well. Having the USB 3 ports is an added bonus.
For gaming, this monitor is the best I've used. Silky smooth and the response time (when set to extreme in monitor OSD) is ideal for any FPS.
Overall just a really great, well made monitor. If you're looking for a 25" G-SYNC compatible monitor look no further in my opinion.
For me, 25 inch screens are perfect for me as i play a lot of online shooters such as valorant/apex legends. The image is sharper than stretching 1080p across a 27 inch screen so i'm happy with that compromise.
240hz is not a huge feeling difference from 144hz, but it is incredibly smooth if you have the PC to run it.
The thing i love about this monitor is the lack of motion blur and smearing. I have it set to super fast and i see literally no fringing or overdrive problems that i have had on other monitors so its perfect for fast paced games.
The bezels are super thin, the monitor looks lovely, the picture is bright and colourful and fast, I haven't had any issues with it so far at all.
The only one issue i have which isn't the monitors fault, is that i have a desk that is 50cm deep, and the monitor takes up quite a lot of space so even right up against the wall its too far forward for me, so i've put the monitor on a stand i can push back further, so if you're lacking space keep that in mind.
While it boasts "true 1ms" this is a lie. Out of the box it comes at 4ms with options for 2 and 1.
1ms causes awful distortions which make games blurry and causes artifacts such as translucent images of previous applications over darker ones and vertical lines which come in and out. I thought this was my panel being broken but dell support have told me this is normal.
I do not recommend the 1 millisecond "extreme" preset in the monitor's settings.
