    • Had to hand it down and simply the best I’ve had thus far
This monitor is a banger even till today

    • A great solid monitor
My last monitor I purchased was in 2007, and when I rebuilt my system I bought all new to include this monitor. At first I bout a 27 inch monitor from a walk in store, because it was the only one the store had. I never thought there would be a shortage of monitors. Then after I bought it, realized it was notGysnc since I have an NVidia card. The 27 inch was way to big anyway. Way to big to use for desktop gaming. It was 4k and actually really nice though. I returned it and spent a few days scouring reviews, what kind, what size, and it was an endless task. I play pc games, and as one site mentioned anything bigger than 25 inches was too much to play desk top gaming. I don't do xbox. They were right, and although this measures actually 24.5 roughly, call it a 25 inch monitor. I am so glad I didn't buy anything bigger. Your field of view can't cover it all. Color is great, solid, and no need for me to adjust it. A very solid base, nothing flimsy about and I love that I can turn off the back lights, that everything seems to have, mice, modems, keyboards, and now monitors. Enough with all that. The box and packing was unlike anything I had every seen, a quality job, and very nicely done. The only thing I jibber about is the cost. A bit high, but if it lasts me as long as my 20x20 square NEC monitor did, it is money well spent. I am not into labels or names, but I appreciate that Alienware didn't go all kid like on displaying it. It's a good display without marketing for young kids, but shows it in a classy way. Cables hide well with a built in organizer and the adjustment of raising and lowering is nice too. I think it is very solid, the exact size for desktop gaming and colors have been very nice and clear. I am glad I bought this. I am surprised how hard 24-25 monitors are to find. This came with appropriate cables too, unlike some vendors, you have to go buy the optional cables. Packing is some of the best I have ever seen. I wanted to give this 4 stars, taking one off for price, but considering I really like this, cost wasn't so much a factor to take a star off, unless someone can tell me there is a generic version of this for much less money. ... show more

    • Excellent for gaming at 1080p
The monitor was delivered very quickly which is nice. The solid packaging prevented any damages to the screen or parts (stand/base). Alienware/Dell make quality products and I hope this AW2521HF lasts for some considerable time (might be cheap for some folk but with international shipping to beautiful Fiji, I paid a total of about FJ$1,300.00) but to complete my machine (have an R11 - was using an AOC 27" 144Hz GSync, also very crisp) price was, on balance, negligible (we live once...at least with current sci/tech). So far I am pleased to say no dead pixels or backlight bleed issues (not paranoid but I first read negative comments/reviews before buying any tech online for obvious reasons - I live in Fiji - shipping costs, even for "free returns/replacements" are not negligible). Played a bit of Deus Ex (alas not the new ones with Jensen, the old classic with JC, the revision version) and also Doom Eternal and while I honestly cannot tell the difference between 144Hz and 240Hz (doubt i'll appreciate a 360Hz) the gaming experience (maybe a placebo) seemed snappier/fresher and overall smooth. Not that I have any complaints with AOC, but Alienware is Alienware. Thank you Amazon for being a facilitator and thank you DHL for the speedy and safe delivery. Also, thank you Alienware/Dell for your quality products. Hope this lasts (we're all very climate/environment conscious now) so I'd rather use quality tech like Alienware for some time to come (until the next tech leaps). Vinaka Vakalevu (thank you) from Fiji. ... show more

Ive had this for sometime now & it still holds up great. No complaints

    • More than expected
I would say other brands are better because of the price but with this your paying for extra features. The box is incredibly well made too keep everything safe, building it was a breeze and it keeps cables very clean. I did have a hard time with drivers installing, it tried to install it immediately connecting the monitor to the computer but it failed so you have to go in stop the download delete it then download the drivers and restart it; this was the only problem I had. It comes with all the cables so no need to buy your own, has controllable lighting on the back and a lot of adjustability with the included stand. Screen Looks great not the best but man it's fast. Overall great buy would recommend. Edit/Update: for anyone who will buy this do not install Alienware command center block it from installing or running if you're using windows 11 it will throw your windows all over the place because it for one is made terribly, I can't find the software to open it everything online says that you can't open the software, and it competes with Windows 11 for where you put application Windows. ... show more
