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.

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.

picture clarity is not that great... but good value for the size.

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.

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.

I received a malfunctioning product. The box is put inside another box. The screen resolution is not what advertised. Speakers don’t work. Cable and other accessories are used. HDMI cable is missing. The worst product ever. I don’t trust buying from Amazon anymore This is the second damaged product in one week.

I bought this screen for trading, Before I searched a lot for trader review but Couldn't find as Eveyone buys such screens for gaming. I must say I love the Quality, price and shape everything is so good.👍

I am working with a gaming laptop and through HDMI it will run 4K up to 120hz I am pretty sure with a desktop PC it will work even better. Quality is amazing and gaming in this monitor feels so smooth and the view is so good. Suggest to use for Desktop PC with Display Cable , will give better performance.
