there is SAMSUNG 27" LC27G55TQBIXCI in operation for a year
AMD Radeon RX 5700 XT 8176 MB
ONLY when turning on the PC after 3-5 minutes (4 times a week, and this has been going on for 4 months) sometimes there are horizontal stripes at 144Hz on the video you can see, if you pull the monitor plug from the socket and turn it on again, the stripes disappear, the monitor was handed over for repair under warranty, they tested it and said there are no problems with it, I don’t see any problems with the video card either, because I took another video card AMD 5600 and the stripes were also there, I took separate DP cables with gold-plated plugs and filters, inserted them into different ports of the card and the same thing - there were stripes, if you switch to 120 or 60, the stripes disappear, but they are not on HDMI, I took the PSU to test - everything is fine, I took the video card to friends - there were no stripes, I bought a UPS with stabilizer - it didn't help, what to do, where to dig next?
