LC49HG90DMUXEN problem when screen is not active during 4+ days

[Pouleman]

Hello,

I contact you because it s been 2 years I got this issue, and now I got a brand new 6900XT, I know this is not a graphic card problem, but a monitor problem :

Everytime I shut down properly the screen when I m going in holidays, when I come back at home and want to turn on the screen, I got very very weird pixels showing up, it fixes itself after a few minutes, or if I log in with another monitor, and move items to "force refresh" on the 49".

I bought the screen in 2018, and would like to replace my setup with another 49" from samsung (odyssey g9), replacing my 2 27" on top of this one, but am afraid to have the same exact problem, and in case this means the monitor is dying, I can t afford to buy 2 49" every 3 years.

Is that normal ? Do someone else experience the same issue?

Cordially.

I have exactly the same issue for some years now. Learned to live with it, turn off and on until it works but it's a nuisance. Happens less when I connect using HDMI.

The real problem is that Samsung never officially acknowledged the issue, even if there are a lot of threads about it on reddit and social media.
Changed / replaced more than 50 screens for my company / family / friends / customers (digital art schools, professional designers) since the issue appeared, and because of this lack of consideration for what can be considered as a high end devices, had to choose alternative manufacturers that are working flawlessly.

Samsung no more.
