This post is a question to other PG32UQXR owners, recently I purchased one of these monitors but it had 2 issues that made me return it, but I am not sure if the particular monitor was problematic or is this a common problem for all monitors of this model. Here is some details about how you can reproduce the issue: 1. Setup your browser to use dark theme (I use google chrome dark theme). 2. Open https://www.testufo.com/ghosting but before that make sure the monitor is running in 144hz not 60hz and let it run for about 2-3 minutes on full screen.
3. Then open one empty browser open google.com for example and since the theme is grey you will be able to see 2 lines across the whole screen and there lines will be exactly where the separating white lines in the ufo image were located previously. This will start disappearing slowly about 1-2 minutes but the longer you keep the ufo test on screen the longer it takes the monitor to remove the white lines and get back to normal.
I have attached two photos to give you an idea of what to expect
If any owner of this monitor read this post and is willing to do this test , your feedback will be highly appreciated, because currently I am debating to order a new one to see if this is common problem or it was just my particular model since I liked the monitor a lot it was good in everything else but this issue was just too big to keep it.
