Great monitor, Bad HDR.
(Monitor on the left side.) Honestly, this monitor is pretty damn good. Especially for its price, the resolution is crisp and you don't even recognize a pixel. The refresh rate is solid, no rug pulling on that, plays games smoothly and has zero input delay. Super easy to set up, pretty much just plug and play (except for the stand.) I enjoy this monitor a lot, it’s very, very cost effective and does not underdeliver. Comparing it to my curved 27” Sceptre (depicted right.) it is a LOT more crisp and has way more vibrant and illusive colors. The sceptre is overly saturated despite changing settings and is pretty buns. The only thing I hold back about this monitor is the HDR. Do not use HDR. It makes everything have an orangey-yellow tint and does not properly work, plus there is only one setting of calibration for the HDR. It has no real effect on the resolution or enhancement, it just makes the blacks darker, and the screen orange.

Great quality for the price!
I was scouring online looking for a decent 1440p 144Hz monitor but didn't want to spend a small fortune. I came across these and decided why not bite the bullet and try them, to my surprise they're actually really nice quality and very solid. Only gripe I have is that the stands are the best and could be more sturdy. Overall an extremely solid monitor if you want 144hz 1440p monitors for a great price!

bad quality control
I bought two for my computer. Then 4 more for others i work with. At first they seemed ok, but now we are all dealing with issues with them needing to be turned off and on or unplugged to reset the connection to get them on. I can only expect overtime it will get worse until they all finally break completely. The picture isnt great but i wasnt expecting it to be at this price. Ive tried other cables, refress rates, resolutions ect...
