Tremendous value for the price

Darth EarlMay 26, 2025

This is a great monitor and for $89.99 on sale it is a steal! Bought it for my home office so I could extend my laptop display to 3 screens. The stand extends to 12 inches vertical, pivots horizontally and vertically. It is very wide and very sturdy. No tools needed to assemble it. Comes with an HDMI cable. I didn't use that, I needed a USB-C to HDMI which I bought separately. Worked great. Only issue is the power cord is only about 4 feet long. I'd prefer 6. But that isn't a deal breaker by any stretch. Picture is great. Again, using it for work, not gaming or media viewing. But perfect for what I needed. Read more

I got lucky?

Just to start off i'll say I've been using this monitor for about 2 weeks now. This review was done in HDR mode exclusively on the 5 pics ive posted all in HDR mode Doctor Strange for some reason my phone picked up alot of blooming on that shot alone think of that pic with like 80% less blooming John Wick All round the monitor did it fine with HDR even in dark scenes The Callisto Proto. limit the nits to 400 and set the brightness right Genshin Impact use of fake HDR think the game looks fine Valkyrie Elysium game really looks good on this monitor This is the Innocn 40" ultrawide 144hz I tested this monitor with a 3080 RTX and a PS5 i'll give the quick for using with a PS5 this monitor has HDMI 2.0 [supposedly] this should be able to output at HDMI 1440p 120hz no problem however this monitor over HDMI cannot output a proper 1440p signal 16:9 turning on Freesync premium will give u a stretched out 4K signal turning off Freesync and putting ur PS5 to 1080p will give u proper aspect ratio and 120hz mind you I only bothered testing it for the fun of it [MW2] <--[1080p 120hz] now for PC use People have said HDR looks bad on this monitor that is not true at all. Its passable its not OMG good but its passable most reviews ive seen mentioning this must have only turned on HDR through windows and not changed the HDR settings on the monitor. If you turn on HDR only it will give u a washed out image HOWEVER turn on HDR windows and Monitor and the colors display properly. I've watched a couple of HDR movies on this screen [John Wick/Joker/Inception/Intersteller/Dark Knight/Doctor Strange So for gaming it has done pretty well with the single player games no screen tearing the screen is extremely bright and colors are spot on however the same cant be said for Modern Warfare 2 when it comes to screen tearing however that is because I most likely forced G-Sync on the display If you want saturated colors ofcourse than just dont use HDR and ur set on most reviews I've seen on this site I can say The blooming isnt as bad as ive seen on pictures [Mine on doctor strange was weird cause i dont see that blooming unless on camera.] this screen does indeed work on PS5 I did not get a single dead pixel HDR is not as terrible as people say [Its not as good as my LG Oled but cmon this is $400] the refresh rate does do 144hz this is a Native 144hz 3440x1440p screen honestly if you have the pc specs for it take a shot this monitor will not disappoint for $400 with these specs its insane For comparison I own a LG CX and Alienware Oled Read more

Great for price, I'm just picky

James DavisSeptember 8, 2025

TLDR; Would recommend for productivity but not (fast) games, be prepared for quirks. Overall, it didn't meet my specific needs. Pro: Budget friendly, great picture, feels well built. Cons: Not idea for FPS despite the response time, firmware feels flaky. Let me start off by saying this is a decent monitor for budget constrained buyers. I purchased this primarily for my work machine for some extra screen real estate replacing my 8-year-old 38" QHD+ monitor. The picture and response time is much better than what I had, so I will say that even though I don't recommend it for FPS gaming it really did well for other games, and I was impressed given the price. My biggest gripe is the built in USB switching is sub optimal and its ability to sleep/wake properly using the hub was a productivity drain. I tried it for a couple of weeks and found it to be annoying enough to mention in this review. My work machine has a (very) aggressive sleep policy, and I ended up having to tap a button on the monitor to wake it up instead of tapping the keyboard many times a day. Secondly there is no software or programmable quick keys to control the switching. This switching/sleep/wake behavior is why I took away the star. Is that a petty thing? Yes. Could I adapt? Yes. Does that change my mind? No. If you are not using the USB switching capability or are using a dedicated KVM then this is probably not an issue. Equipment used: MacBook Pro M1 with USB-C docking station connected via single USB-C connection Ryzen5 2600; RTX 2700 Super via Display Port and USB Note: I had similar experiences as other reviews concerning G-Sync. This monitor doesn't advertise that compatibility, so I am not taking anything away because of it but want that statement to be in the reviews for those looking. Read more
