    • 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

    • Great monitor
I've had this monitor for a few years now and it has been a great investment! Graphics look great and adjustable height/rotation. Still perfect for the things I use today.

    • Say what you want about Alienware but...
I bought this monitor to use alongside my Xbox Series X. Now now, I don't want to hear anything about "console gaming on a monitor" blah blah blah. My Xbox is a Call of Duty machine and I play most my game on my PS5 on a 4K tv anyway... NOW! With that said, this monitor supports FreeSync, 1080/120 (higher refresh rate than that but all I care about is the 120hz), and it is perfect for me to get competitive in a good COD or BF match. It has tons of settings and the image is crisp and clear. My only issue is I sit near a big sliding glass door in my master bedroom and the glare during the day is awful. Messing with brightness/contrast settings doesn't help. I won't knock it to the monitor. Just don't get it if you'll have light glaring right onto it is all. Oh! It also has the cool Alien FX lighting witch has a ton of LED color options for the back which light up pretty well against the wall at night in the dark. Overall, this is a very good, cheap monitor to do some gaming on. Included is HDMI, Display Port, and USB cables and it has good I/O support. ... 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

    • Best 240 hertz monitor at this price point!!
This monitor is basically always on sale at around 300 dollars, which is a total steal for such a premium monitor. Pros: -There are no dead pixels. -No ghosting at all. -RGB on monitor stand. -no backlight bleeding -The IPS display makes the monitor feel extremely premium. -Stand offers tilt both left to right and up and down. -Minimal bezels. -Easy assembly -The menu on the monitor is easy to access and change with the use of a joystick on the back of the monitor. -Though obvious, this monitor does come with all the necessary cables. Cons: -The stand is very big, so though it has RGB, it would actually be better to get this monitor mounted as it takes up a lot of desk space. _______________________________________________________________________________________________ If your budget is around this price point, this monitor is a total steal. Most monitors at this price point are all 144 hertz, and I would really recommend getting this monitor as it both future proofs your set up while giving you the best experience for your budget. ... show more
