KOORUI 27 Inch 4K Monitor Computer UHD(3840 * 2160) IPS Display, 99% sRGB, 90% DCI-P3, 1.07 Billion Colors, Displayport & 2X HDMI, VESA 100 * 100mm, Tilt (N07)

So far so good, nice 2k display, 27" monitor, refresh of 100, colors are bright, everything checks out and it's been running well. No dead pixels or anything damaged. Overall a nice monitor~

IMO the Koorui S01 is an outstanding monitor for the price. I bought two in July 2024 for use as left and right monitors in a three-monitor setup. At the time I kept my original monitor in the center. In Feb 2025 I decided to replace it, as it was quite old and the image quality on the Kooruis was noticeably sharper.So I hopped on Amazon to order another Koorui S01, only to find it could not be shipped to my location. I ordered a different brand with identical specs which happened to be a few dollars less expensive. It arrived, I set it up... and was promptly disappointed. Image and video quality were similar but text was noticeably grainer than on the Kooruis. Text on the new monitor simply wasn't as clear regardless of monitor settings (and I tried every possible combination). I returned that monitor, found the Koorui S01 was available from another online seller, and ordered one.I'm not a gamer, nor do I do video editing or other graphics-intensive work, so I can't speak to how well this Koorui would work for demanding applications. But for ordinary home or business use this monitor in combination with a decent graphics card gives outstanding results. Highly recommended.

It is a great monitor for the price. The colors are bright and in most respects works well as an external screen with lots of display space. The only negative I have is that it has a slow start-up time and from my experience, if you want to use it as the primary display, you may end up resetting it as the primary over and over. In Windows, it doesn't detect it right away and doesn't think it is connected. Then it finally shows up, but is now your secondary. Other than that, or if you have it in an always-on scenario, it should work fine.

Honestly, I was a little concerned about buying an unknown brand when I bought 2 of these for a work-from-home setup. That was 3 months ago. I have had zero issues with the product. It is exactly as described and works perfectly for the work setup. One is connected via HDMI and the other via USB and both have worked flawlessly. Setup was simple and effortless.Would buy again.

This monitor was a good budget for me and this monitor was perfect!

Screen looks great. Performance meets my standards. Monitor is very light but build quality doesn't seem to be affected. I like the light weight because I will be putting it on a vesa mount arm that can be moved so light is definitely better. Viewing from definitely angles is really good

Excellent product and easy to ensamble

This monitor is bright and shows a lot of detail. It's my first 4K monitor and I'm shocked at how much sharper everything (including text) is. I can't speak to the monitor stand as I use a VESA mount for the screen. Setup was easy and my Windows 11 Pro PC immediately set it at 4K and enabled HDR10. I'm using the HDMI cable that came with the monitor One other thing I like about this monitor - most monitors I’ve had have an annoying power light in the front (usually bright blue). This one has a fairly dim white light underneath the monitor that points down at the desk so it’s almost unnoticeable. I would buy this again in a heartbeat.A couple of things... The VESA mount is a little odd because the top two holes are raised but the bottom two or not. This meant that my screws for the lower holes were too long so I had to find a washer to fill up the extra space. Seems like a weird design choice. Also, the monitor manual isn't all that accurate. It mentions the VESA holes being 75mm but they're actually 100mm.Note: Some people keep mentioning that it's not a 4K monitor because their device isn't showing it as 4K. I can vouch that this is absolutely a 4K native panel. If the device doesn't recognize it as that, my guess is that they're using the wrong cable or their device is set incorrectly (or maybe they have a defective monitor).
