KOORUI Monitor, 27" QHD IPS Gaming Monitor, 170Hz, 1ms, HDR400, Compatibility G-Sync and FreeSync, Tilt Pivot Swivel Vertical Height Adjustable，2 HDMI 2.0 & 1 DisplayPor 1.4, 27E3Q

Love the image quality the resolution and the display over all, it was easy to assemble and the configuration, the menu could be better but for the price is just great.

I personally unable to notice any smear or ghosting. hdr is pretty good. But it can only run on 165hz in 10 bpc mod, or in the other word, if you want hdr, 165 is the officail max refresh rate. But you can use custom resolution in you gpu drive to push it 20 hz more. Halo exists, but require careful observation in high-contrast scenes to be visible. Small view angle, must be used as main moniter.

This has been an amazing monitor. Have zero issues. Had it for a few years now. I do play competitive (overwatch 2, warzone). It handles very well. Very good image. No ghosting. Solid.

Great after sale services. Seller has replaced missing VESA screws in past orders after I reached out, and confirmed the same issue has been resolved in this year. You will be able to install the VESA monitor mount with VESA srews provided.

I bought this back on July 18th 2024 and on March 21st 2025 it has not stopped working… Iv done very trouble shooting you could possibly think of, even switch the hdmi cords and also trying my dc port as well nothing has working… my outlet is fine, the monitor has never been dropped, or been hit… i have a tv all the way back in 2018 that is now in the closet but it still works, explain how my monitor just randomly stops working… this is definitely on your guises end not mine. Thanks for wasting my money!

OverviewGreat monitor for the price. I was looking for a relatively high refresh rate, 1440p, 27" LED monitor, and this one provided everything I wanted while staying within budget.Pros:- Excellent value for money- 1440p resolution- 27" LED display- High refresh rate- Versatile stand with multi-directional adjustment- Competitive (arguably better) with name brand alternativesCons:- Stand height may be insufficient for some setups (ended up purchasing a monitor arm)- HDR function is poorly implemented:- - Comes enabled by default with poor calibration- - Color adjustment is locked while in HDR mode- - Had to switch to SDR mode for manual color calibrationPerformanceI don't use this for gaming, so I can't fully evaluate the refresh rate performance, but I noticed no difference between this monitor and my 14" MacBook Pro display.ConclusionFor anyone on a budget looking for the best bang for their buck, this monitor will not fail you.

The media could not be loaded. I bought this monitor for my PS5, and it does output 120Hz at the resolution indicated on the monitor. I tested it with Devil May Cry V (after all, only a handful of games support 120Hz on PS5...) and I'm very satisfied so far. I have it connected to the console's original HDMI, and of course, to activate 120Hz, you need to follow several steps in the console's settings, in addition to having a game that supports high frame rates.If I have future problems with the monitor, I'll let you know in this comment.

It's been a great monitor so far. No issues, no dead pixels, nothing. I don't think I'll ever buy a 24" monitor again.Also fitted my monitor-arm just fine that connects to the back of my desk.
