Great monitor great graphics

Amazing

My monitor failed after 16 months. It powered up and all the buttons worked, but just a black screen showed.It isn’t well highlighted anywhere, but I emailed the manufacturer directly to explain.I had to pay to return it, however a brand new replacement was sent on receipt of the failed unit.Good customer service, and that is why my review has been updated.

Good

I bought 2 of these exact monitors in November of 2022. Like many other of the 1 star reviews, I too had issues.This product needs taking down from Amazon as it is clear they have no regard for looking after users who run into these issues.Initially, they worked great, the picture quality wasn't bad (I did have to change the colour profile from limited to full in NVIDIA's control panel to make it look better) and looked very smooth at 144hz. I was happy with my purchase at the time.However, it wouldn't be long before the issues, at least with this particular model, to begin emerging. It started with the panel that I used as my secondary monitor: Flickering, I thought something was up and it only did this intermittently at random times for a short period of time, so I wasn't too fussed about it given it was my second monitor, but afterwards it suddenly went black with only a tiny bar at the top visible, around 1 to 2 millimetres I'd say. Switching the refresh rate to 120hz fixed this issue, but only temporarily.After a while on 120hz, the issues began again, leaving me no choice but to go down to the last step in the allowed refresh rates, 60hz. Again, given this was my secondary monitor I wasn't too bothered. It sucked, but wasn't bad enough to initiate a return given I'd have to send both monitors back, including the working one as I bought them as a pair.I thought this was the end of the issues, and that there would be no possible way the first monitor would also begin exhibiting these issues, however I was wrong, as not long after I went away for a few days and came back to a non functioning monitor, showing the exact same behaviours as the second one which failed months earlier. The monitor was in standby mode while I was gone, so it appears to just be an issue that grows over time. The only difference this time is that I could use the monitor on 120hz for quite some time without the issue emerging.At this point, I contacted Amazon who said I should contact the seller directly as a lot of time had since passed. This went nowhere, as I went back and fourth with their customer support team with 24-48 hour response times. This was inconclusive and I left it there, cutting my loss.This is not the end though, as the first monitor on 120hz completely broke down after a game accidentally switched it to 144hz in full screen, which rendered it completely unusable even on 120hz and 60hz, as it keeps blacking out. As the second one still worked on 60hz, I eventually swapped them both so I'd at least have a stable, semi-functional monitor to use as my main monitor.At this point, I once again contacted Amazon stating that the seller was uncooperative in helping me fix the issue or get a replacement. At the same time I also contacted the sellers customer service, who finally offered to replace them if I sent them back, after paying for shipping MYSELF. I went with Amazon's return as it'd appear cheaper, who finally admitted defeat and allowed me to return the monitors, but of course not without any hassle.I was told that I needed to print out a label, and have the monitors boxed up with said label attached so Evri (courier) could collect them. The issue? They never came to collect them, and after talking with Amazon a week later I was told that I'd need to take it to a drop-off point instead. Now, I don't have a car, and my closest drop-off point is a fair distance, and I wasn't carrying two monitors and all of their accessories in a flimsy box all that distance. That, and all the time I spent waiting for the courier to appear to collect them, the deadline for when "I should send" the products back had passed. I could have paid for a Taxi to help me drop them off, but that's just an additional cost I'd incur sending 2 faulty products back that I might not have even got a refund for.Just not worth the hassle. I'm down 200 quid with two broken monitors that no one seemingly wants to take responsibility for.Something needs doing about this, and I'm astonished they're even still being sold! Amazon, DO SOMETHING!

Works perfectlyBeautiful

This monitor is probably the best for its price.The customer service is also pretty outstanding as I told them about an issue I had with my dc adapter, and even though I bought the monitor in 2023, they were willing to send me a new adapter when I told them about the issue in 2025.

Monitor is good quality, does the job for work.Issue with power cable 18 months after purchasing. The company quickly sorted this and sent a replacement, very good customer service.
