A great value for a state of the art monitor.
I use two of these at my home work station. I am not a gamer, I use these mainly for working on multiple spread sheets and financial programs. The high pixel count of these 8k video displays makes it easy to read the screens. I have Windows 11 on my computer, so installation of the 3 monitors was easy. I have my computer monitor set at 150% and these two monitors set at 125% magnification. All three are at eye level. They came with display port cables which my computer and hubs do not have, so I in a 8K HDMI cable for each. I do play a few videos, and those look great. The curved screen helps in keeping all the monitor sort of equidistant from my eyes which helps everything on the 3 screens stay in focus for my 80 year old eyes. I have reflections on my computer screen, but both of these Koorui monitors are reflection free. I first went to Costco to pick up a monitor and this allowed me to zero in that I wanted the 8k and curved screen in a 24 or 27 inch monitor. They did not have that combination. I tried just one of the Koorui monitors along with my older monitor. The Koorui was so far superior that I quickly purchased the second one and tossed out my outdated one. I use these for hours each day, and at this low price I feel I can easily justify this investment. I feel secure these monitors will be with me for a long time.

This sucks.
Well i picked this up on sale for black friday and finally got around to installing my new video card, psu, extra ssd, and finally hooking up this new monitor. The new video card doesn't have a spot for the cable from my old 1080p monitor, so this is the only monitor i can use. It's christmas eve btw. Anyways the monitor fires up fine and looks great for about 6 hours of use. Then as i'm getting ready to boot up elden ring a big vertical magenta line of pixels appears on the right half of the screen, as well as a grey horizontal line of pixels. I didn't do anything before this happened, the monitor was sitting completely still on my desk. One second it worked the next i've got this line. I tested another cable, and while unplugging the displayport cable from the monitor the pink line stayed there as it was registering "no input." So it's definitely the monitor that's broken and not something wrong with my video card or software. I tried contacting technical support early in the morning and still haven't received anything at 5 pm. I realize it's christmas eve but I'm now stuck without a functioning monitor for probably my entire time off for christmas, and will have to pay return shipping, which soaks up all the money i saved getting it on sale. Over all i'm very unhappy with this purchase. edit: Koorui, the manufacturer, never got back to me about the broken monitor they sent me, so i contacted amazon and told them my situation. they told me they couldn't send a replacement because it wasn't available, even though you can order the exact monitor off amazon through prime right now. this order was a critical failure in service with both koorui and amazon. they can't seem to lift a finger for someone who paid them money for a product they sell. they want me to ship the monitor back, receive my money back, then purchase the same monitor for a higher price from them. I'm changing my review to 1 star and i would give 0 stars if i could. unbelievable. edit: ok i shipped the monitor back. they sent me a replacement monitor and this monitor also does not work. it doesn't turn on. i plugged it into both a surge protector and a power strip, then switched the cable and it doesn't turn on. i would be extremely wary of this company and their products. edit 2: by far my worst purchasing experience on amazon. with the second broken monitor they shipped me the support guy actually asked if i would take it to a tv repair shop. i told him we don't have that in the united states and returned the item for a full refund. they got to keep my $150 for about 3 months though. these people should not be allowed to sell on amazon.
