I just plugged it in and changed the settings

The monitor arrived very well packaged and I simply connected it and put it into operation. I don't remember 1080p being that useful. Color and brightness are excellent, text clarity is good. Make sure to check your resolution after connecting. I'm stuck on a 2560 x 1440 display which caused the text to jagged and the refresh rate got stuck at 144Hz. I'll play it a bit tonight and give you the details.

Excellent monitor in my review

This monitor is really well made and the stand is very stable. The picture quality is excellent and for me it was worth the money. Love it!

Light touches 1 are good for me

If you can handle 360Hz performance and like games per second, you can scream and be an Edshot machine 😩😈 Limited energy efficiency.

DOA is here - my new review

The product looked good but didn't turn on at all. I've tried everything. I do not recommend spending $430 on a dead monitor!

Dell will not honor the warranty

Died after a month of use. It does not begin. Despite 4 months of trials, Dell cannot provide a replacement/refund or anything like that.

Great monitor, but TN still wins

Everything about this monitor is amazing when you have the GPU power (with the 3090). Knocks out my TN in everything but one thing, how quickly my inputs appear on screen. Please make someone TN at 360Hz.

Nice, heavy, reliable design.

Coincidentally, this monitor stops working when turned on. Will it be covered in random colors/pixels? Won't go away until I unplug it from the wall and plug it back in. is mine broken? It was very expensive and I love it, but it worries me when it flashes a weird screen that doesn't go away until it's turned off. I don't know if I want to keep it. I have 3 Smasung monitors, 1 Dell monitor and this Alinovar. This is my favorite aside from the occasional cluttered screen that sometimes pops up…

360Hz vs 240Hz is the best in my rating

- Very bright - 360Hz instead of 240Hz seems like a faster and more responsive 240. I've been using the 240 for almost 2 years and have used many different 240 and Asus 280hz panels. You can tell the difference. Gsync works very well. Some will say that you should use unbounded frames without gsync, but this monitor has zero latency. with gsync enabled and capped at 355. your eyes will experience pure bliss from smooth gaming. My final conclusion: 360Hz After a few days of use I noticed an…

The best of the best. the best in my rating

Went from 240Hz to this one and you can see a noticeable difference. Remember that you need a strong card to push the right frames. I'm only getting low 300's and it's still noticeably better.

Monitor turns off randomly

I love all the features of the monitor but there is one major problem with this monitor. When I'm using it, it randomly turns off and I have to press a button to turn it on - it's not a big deal if you use it for everyday tasks, but I think most people buy this monitor and use it for gaming horrible experience when you are in a game and your monitor goes off in the middle of the game and you have to manually turn it back on and it takes a few seconds to turn it back on. Those precious seconds…

Disappointed at first, but grew with me.

The first monitor came and the display cracked (half the screen was dark and only part of it was lit) so I had to return it which was a painful process but the new monitor came and was definitely a 144hz upgrade. I immediately felt the difference between the two and the picture quality is amazing compared to my Asus. The purchase was worth it.

  • Never

Improved my recording speed in FPS by 3.4x. A very sharp image where you can see much further than my previous Acer VA panel which is also very clear but slow to respond. But it's in the bottom left corner, a big dead pixel. Too bad the tech team didn't spot that in production. Leaves a lot to be desired. I have to send it back for my own money.
