KOORUI 21:9 WQHD 3440 * 1440 4K （HDR 400）34 Inch 1800R Curved Gaming Monitor, 165Hz MPRT 1MS (AMD FreeSync Premium Nvidia G-SYNC) Hdmi DP 90% DCI-P3 OSD Roker Computer Gamer Monitors

This monitor is actually incredible. And for the asking price, it's major worth for the price you pay. A 34" incher with a 4K wide res, along with software simulated HDR is actually amazing for this price. The monitor is almost identical to the Samsung G5, and has almost similar specs, but in some ways I feel are better. It has punchier colours as well. Overall, incredibly worth the price.

Great price for a 34” 4K widescreen monitor. Quality looks good, lots of inputs.

This product is very good in terms of clarity and offers excellent support for the PlayStation 5 Pro. It also provides good support for Ray Tracing and HDR features.However, a drawback is the overly intense red color, which requires adjustment. Unfortunately, when HDR is enabled, you lose the ability to modify the colors, which can be frustrating.Overall, it's a solid display for gaming, especially with its PS5 Pro and HDR capabilities, but be aware of the color calibration limitations.

It works 165hz only on DP port, needed and extra cable do to Usbc but after that works amazing. Very good display, clean and minimal design. 34” productivity monitor is great. Not a gamer or a video editor, just needed multi tasking with excels, if you are too close to screen can see the pixels, with decent distance works like a charm, used it only for few days need to see how long it hold up.

I hesitated buying this because a few reviews said it was not really 165hz but only 100hz but I rationalized that 100 was better than 60 anyway and the price is too good. I can now say it is a phenomenal screen for pc gaming, and yes if you use an HDMI cable chances are you will be limited to 100-120hz but the screen comes with a DP cable, which will give you 4k@165hz, for tv HDMI will be fine but if you game with a console or PC, use the DP cable to get the higher refresh rate and to utilize the screens FreeSync. Also check your pc settings like nvidia control panel to set the refresh rate. Awesome screen for an awesome price.

I bought this monitor, everything works well until I found that my maximum hertz is 100 only, I bought HDMI 2.1 cable and same issue, I plugged my laptop into another monitor that supports 165Hz and it worked the hertz went 165, so the problem from the monitor, the support was so bad they answered me in short silly sentence.

I’ve been using this monitor for about a month now, and it’s exactly what I wanted. The image quality is sharp, the colors are vibrant, and the 165Hz refresh rate makes everything feel super smooth.I noticed some people saying they’re only getting 100Hz — that’s because they’re using HDMI. If you want the full 165Hz, make sure to use a DisplayPort (DP) cable. That’s how you unlock the monitor’s full performance.I highly recommend this monitor for PC gaming, but not really for consoles — they can’t take full advantage of what this monitor offers. For PC users though, it’s a solid choice.

So far it serves its purpose and its still working, great for productivity, good for gaming. Colors are ok, sharpness is ok, my 27-inch is better but you get a lot for the money. Refresh rate is fine 165hz only works using DP. no split screen option, but windows have it anyhow.It's ok.
