### ⭐⭐⭐⭐⭐ Amazing deal. ENABLE HDR!!
*by  on Reviewed in the United Kingdom 16 May 2025*

A like-new condition 40-inch 144hz 1440p monitor with full USB type C docking for £307 was crazy, so even though I was initially in the market for something 2-3x that price I couldn't pass it up.It's a big monitor, intended to be used at a distance, which is perfect for me. The area is almost twice that of a 27 inch monitor. At this size I can read on-screen text without increasing the UI scale so there's tons of space for productivity.The biggest con is that the lack of curve causes the edges to appear slightly darker than the centre, but after a week this didn't bother me any more. The second biggest con is the typical LCD grey-like blacks, but for the price it's not a deal breaker.Enabling HDR is a must, and over USB C this will require the cable supplied in the box for the necessary bandwidth. This fixes the green-tinted and flat colours it otherwise has, and now I'm impressed with its warm, natural and vibrant colour presentation and strong brightness. Video and games really pop and look stunning, as you can see from my photo of Assassin's Creed Odyssey below.Even if its pixel response time figures fall behind other 144hz LCD monitors, motion looks good and plenty clear enough in person.Overall, super good deal and I'll be keeping this monitor for a while.

### ⭐⭐⭐⭐⭐ Amazing for the Price!!!
*by  on Reviewed in the United Kingdom 30 December 2023*

It is excellent well built monitor. It is big but not too big for my desk which is only 65cm deep. It works in 120hz when connected through displayport what is very important to me as it is double speed of the standard 60hz. It can go up to 144hz but I do not use it at all. It only goes up to 100hz over HDMI. Personally I feel that there is not much blur like many people and reviewers complained about. It is big upgrade from my 32" Viewsonic monitor. There is way more space available on the desktop, colours can be set to pop out of the screen, menu is very comfortable to use, contrast level is good enough. I am pretty impressed with the quality of the picture and the feeling of smooth movement in 120hz. It works great so far. Also there is EU and UK power lead included and HDMI and DisplayPort cable as well. I definitey recommend this monitor to anybody who wants bigger screen than standard 32" 16:9 monitor - it is real solid upgrade. At the moment I feel that anything bigger would be just too much but if there was a 42" version I would probably buy it instead and upgrade the desk to 80cm depth.

### ⭐⭐⭐⭐⭐ Perfect for me
*by  on Reviewed in the United Kingdom 20 July 2024*

Incredibly happy with this monitor. It's a large monitor without being ridiculous.It's not too big that you'd rather have a curved screen.I've seen some reviews saying the remote has a narrow ir beam so you have to point it directly at it. Not sure if they fixed that in later builds, as I can point the remote in a totally different direction and it works.I bought this to use for work, and some mild gaming. The single USB C cable (not included, you'll have to buy one, make sure to buy one that supports display as well as charging, searching for USB C 3.2 should find you what you need) makes for a much cleaner desk setup. And worked straight away with my work laptop.I had some trouble connecting my steam deck, as it doesn't seem to support the 144hz refresh, but dropping it to 120Hz resolved the issue.Only had it a few days but so far very happy.
