Tremendous value for the price
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.

Good Monitor
Before this I had the LG 34950F, and in less than 2 years it developed vertical lines (common issue), in my search I was looking for another brand, then I came across the Sceptre E415B-QUN168B, months later this one was in stock and I decided to give it a try, but I like better the base on this one.The price with the promotion was reasonable, the specs was similar to the Sceptre and it is Flat (I donât like curve monitor).To use HDR activate it in Windows and in monitor settings and set the SDR content brightness to 100%, but it didnât convince me, so I donât use it.I just noticed that on my AMD System (3700x, RX 5700 XT), the memory clock stays at itâs maximum even at 60 Hz, only on 50hz went down to 200 Mhz, and creating a custom resolution with reduced blanking didnât work, try to add LCD Standard value to CRU, but it can reach just 119hz not more, this consume more than twice GPU power resulting in more watts, with 50hz the GPU consume 11w – 12w, on 144hz 38 watts, increasing also the temp. My other setup uses HDMI with 100hz on a GTX 1070 TI with no problem, in my experience with other monitors, by using 120hz reduces the memory clock while idle,.Watching movies was a great experience, because it is Flat, I donât get that fish effect, the games where amazing and this is where the monitor shines, it was great, did not notice any mayor ghosting, and the size was perfect, much immersive than the LG 34 inch.Update: I managed to add a 3400×1400, 144hz and 767.76 pixel clock and the display freeze and then no display, it was complicated to troubleshoot it, I end up swapping to an old RX 580 and one ram, boot in safe mode and run reset-all.+ Price with promotion+ Size+ Good color out of the box specially on sRGB+ Refresh Rate+ Flat (personal preference)+ PIP+ No pointless RGB+ Square Metal Base (No V shape, takes more space)+ Auto Input Signal+ Dynamic Onscreen Refresh+ DCR (Dynamic Contrast Ratio)- Packaging could be better, the metal base was loose when I opened it.- No protection to the screen on packaging except for the cover, screen had stains.- The arm does not click automatically on the monitor, had to force it.- Gap for cable management could be set higher to hide cables- The Dynamic Brightness (or whatever would be) its like always on with HDR active in Windows, and itâs not good (watch included video,)- Two displayports would be ideal for people with two systems.- OSD is a pain at first- No good HDR- Generic Windows Drivers- At the time of writing no information on manufacturer website- Update: Found one dead pixel in the right bottom corner, the task bar was hiding it.I just had it for few days, and I hope not to have the same experience as my last monitor. In the end, I donât miss anything of the LG 34GK950F, not even nano-cell technology.I really like this monitor, itâs not perfect but the price was good.Update: After 2 years, keep going strong.

Great for price, I’m just picky
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 connectionRyzen5 2600; RTX 2700 Super via Display Port and USBNote: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.

Excelente monitor calidad precio, pero a los 3 meses de uso me empezaron a aparecer lineas verdes y moradas en diferentes zonas del monitor…La verdad me arrepentà de no agarrar el PROART de Asus, supongo la calidad de ensamble es mucho mayor a esta marca china

This is my first ultrawide monitor. Had a 24″ monitor before for work, now I have my ps4 hooked up to it as well and the colours and very casual gaming are really nice on there. I do wish it had an output function like a usb hub as I’m having to connect my speakers and keyboard via bluetooth to the mac airbook m2 laptop while keeping the aux connection for the pc laptop set up.Aside from that, I’m not a monitor snob and don’t need super duper accurate colours as I don’t edit videos or photos for work so I can’t speak on the quality from a professional front. But if you’re someone who works using online communication platforms, excel sheets, and mostly just do administrative work, this one’s great with all the screen real estate. It’s also not so big that it takes up so much space. It’s also really great that it comes with the USB C cord for video input – I mostly got this monitor for this reason so that I can minimize cable clutter.The monitor stand it comes up with is actually really useful and can be raised up higher than most as it has to be long enough for the screen to rotate to vertical mode. It’s easy to install and so far, everything’s in good working order. Love it. Glad I went with this instead of an LG or Samsung ultrawide for the similar quality and likely at least $100 more.

I was looking so forward to using this monitor with this functionality but can’t get it to work or monitor to stay on. No support. I’ve looked high and low and only purchase FAQ’s. This was a waste of good money for a half completed monitor. I responded to the email and no answer back still 🙁
