I purchased the 4K 144hz model of the Odyssey G7 (LS28AG700N), and am having some extremely irritating issues with the input cutting out:
Anytime I have the Odyssey focused on an app or game in fullscreen or borderless mode, and I click over to another monitor to use another app for a moment (replying to a friend, googling something, changing music, etc), it makes the input for the Odyssey completely cut out for about 2-3 seconds, then it comes back on, displaying "HDMI" in the top left corner as if I just turned it on, then, it does it again when I click back over to the Odyssey, totaling several seconds where I can't see the screen. It's not just visually unappealing, but very disruptive in intense games.
I'm using a HDMI 2.1 cable, but I did also test it with the DisplayPort cable that came bundled with the monitor, same result.
The only way I've found to "fix" this issue is to lower the monitor's refresh rate to 120hz, but that's certainly not what I paid for. Even with the color depth set to 8bpc on 144hz, this issue persists.
Why does this happen? It works fine and looks wonderful while tabbed in on the app/game, but the input flickers every single time I click over to another monitor, no matter if the color depth is 12bpc, 10bpc, or 8bpc!
Any other Odyssey users experiencing this or know of a fix? Thank you!
No, but my previous monitor didn't match it either.
I should've clarified that it's not specifically clicking on another monitor that triggers it, but clicking to another program while in fullscreen. For example, it happens when I alt+tab or hit the windows key - even if the 2nd monitor isn't plugged in.
I've found that switching to Windowed Fullscreen in each of my games/apps fixes this, and while the difference in FPS is present, it's negligible. So I suppose that's the solution.
If I were to theorize on why it's an issue to begin with, I'd assume it's because 4K @ 144hz is technically overclocking the monitor, which affects the resolution of the desktop in the background - Samsung only commercially advertises it as good for running 4K at 120 fps, or 2K at 144 fps after all.
I also have this problem with my g7, the problem seems to be gsync. If its enabled it happens , even lowering max refresh rate in windows doesn't help me. Seems like we have to contact supports coz i found no solution in the internet, like many ppl have this but can't fix it. Although some fixed it with new windows or windows/gpu drivers update
