I bought the 32inch version in May thinking it would be the best of the best. Turns out Samsung does NO QA on this product at all, and the process for supporting the monitor and fixing the issue does not exist.The common problem for this monitor is that is fails an inversion (pixel-walk) test at its rated setting (240 hertz) and needs to be turned to a lower setting like 144hertz (or lower) to have a normal picture. In the multiple attempts to service this monitor, all of them had this issue. I also ran into one instance of screen flickering.The impact of it failing a pixel inversion test is that it will struggles with certain images, For example if there is a blue gradient it will produce CRT like scan lines. This is not the only scenario that will cause this to happen.Starting with the first Monitor, It had pixel inversion problems at all refresh rates. I called up Samsung and they said to send it in. They did not provide me with a box, only the shipping label, and I had to pay about $100 (in packaging) to have it shipped via UPS. They received it, and it got damaged in shipping. Samsung wanted $150 to repair it. However after a call to their service department, they waved the repair fee.After the first repair it STILL had issues with pixel inversion, at all refresh rates. So I sent it in again. Luckily I kept the box this time. I'm left monitor-less for about 2 weeks, because they didn't have the part to repair it.After the second repair, it is able to run at 240 hertz with no pixel inversion... for about 1 week, then it started happening again. I was so drained from the service process that I set it to 144 hertz, and said screw it, I can live with it. Then I started to notice issues with the screen flickering in dark scenes.About 1 month later Samsung started blowing up(texting me multiple times and calling twice) my phone saying I needed to send in the monitor. I had not asked for another service... I called to make sure it was legit, and they informed me that they have a replacement for me and I need to send it in so they can ship me a brand new one.So I sent it in. Little did I know this would be the worst part. I sent it in July 18th. I receive a message from Samsung on my phone July 19th saying the repair center has received the monitor. But don't hear back from them for a week and a half. I call into their service department, and they tell me they haven't received it yet. I ask them to expedite the issue as I had to move August 1st. They say they will.It was now August 2nd, I haven't heard back, and I have moved. I call again, cause I need to update my address... They still don't have it. I politely ask to speak to one of their supervisors. The supervisor calls back several hours later and I tell him the whole ordeal. He informs me that they will just issue a refund... So in the end, I did not receive a working monitor, wasted about $100 dollars of my own money, and dozens of active hours trying to fix this, along with months of not having a monitor.This monitor should be recalled. If you check the internet, tons of people are having this issue. If this worked as advertised then this would be a great monitor. As it stands I can NOT recommended this, also I would not recommend Samsung at all after the multiple failed attempts to get this fixed. I can understand some monitors having issues and needing to be serviced, that will happen, but if you do not QA your own repairs, whats the point?TLDR: Samsung Failed to provide me with a working monitor after 4 attempts, (between the initial purchase, multiple repairs and replacement) They left me monitor-less for about 2 months total, cost me $100, wasted dozens of hours of my time, and they just gave up on trying to get me a working monitor and issued a refund. DO NOT BUY.Update:After not hearing back from Samsung for over a week, I called their support again, they informed me that it was going to be a week out for a replacement, which was odd as I was told by the last rep, that I was going to be getting a refund, the Rep lets me know that a refund would take 2-3 weeks starting today. I ask to talk to a higher up and they tell me the same thing. I wanted a refund, so the started the process, they proceed to keep me on the phone for 30 minutes to "generate a ticket number".Added screenshots to show issue at 240 Hertz (also a screenshot of it not showing the problem at 144 hertz) that I experienced after all of Samsung's attempts to fix the issue.Total Number so far.Time to resolution for the issue: Still pending currently 3 monthsTotal Time on the phone with Samsung support: 3 Hours 46 minutesAttempts to fix/replace: 4Money spent on shipping: $80
