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.

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.

Good screen , downside : do not rely on the screens audio jack for speakers. There isn't much power coming from it and speakers end up being low volume. 2ndly no USB ports either. Other than that it's a nice screen

شاشه جميله وعمليه ودقة الوضوح فيها عاليه جداا

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.

Haven't had any issues with it. Doesn't lag, hasn't had any malfunctions, colors are nice and not overpowering, very sturdy, isn't blinding so the brightness is just right.

Es buen monitor para gaming si no eres demasiado quisquilloso con los colores ya que tiene una gamma del 83%, lo cual no es nada bueno para creadores de contenido digital artistico, sea dibujos, renders, ediciones de video etc, sin embargo, el tiempo de respuesta y la tasa de refresco ayudaron mucho con mi K/D ratio, subiendolo de 0.7 a 1.9/2.0, increible, aun asi, por el precio es dificil encontrar esta resolución, y mi unico descontento es el ghosting de los colores negros u obscuros a cualquier otro y que sea VA no ayuda mucho con el problema, considerenlo como un monitor de entrada, aunque les recomendaria ir por un LG UG de 24in

Whilst the picture quality isn't bad, the instructions are extremely poor. There are no markings as to what buttons functions are allocated. I had to guess which button was power on/off, I still don't know what the other buttons do......Thats anyones guess. I like to leave my Mac Mini switched on sleep mode when I'm not using it, it's at the point when the screen goes blank that the monitors LED flashes on and off quite brightly, this is so annoying to me because my Mac and monitor are in my bedroom. God only knows if it's possible to switch the LED off........ Really can't recommend this monitor it's CR*P.

Screen quality is really good. Huge 27 inch screen. Great value for money
