Acer Predator G-Sync : Bug

7Z7

Hello everyone

 I have a little problem that bothers me, I'm afraid my Acer Predator (XB271Hbmiprz) screen is defective (not knowing more than that), I cross my fingers that it's the pilot who's causing it. I've had this for some time now, I'll explain.

 I am on my desktop, in Normal mode (G-Sync is disabled). When I decide to activate G-Sync, the screen flashes, I think it is activated but when I look in the menu of my screen, I realize that I am still in Normal mode as if it was not activated. So, if I start a game, I switch from Normal to G-Sync and every time I switch between the Desktop and the game (or switch to or leave the Full Screen mode of a YouTube video), I have my screen blinking for a second indicating that it alternates between Normal and G-Sync mode. Sometimes I get in the game, G-Sync is activated and I decide to increase or decrease the sound, I have the volume bar that appears on the screen and just that, it makes the screen blink. This means that when the volume bar appears, G-Sync mutes to be in Normal mode and once the bar disappears, the screen flashes again to switch from Normal to G-Sync. The only solution to prevent this flashing is to restart the PC.

 I've had my screen for two years and at the very beginning, I didn't have to restart my PC every time I turned on or off G-Sync. And that's when I have another more or less similar problem.

 When I am in G-Sync mode constantly activated (so I have previously restarted my PC so that it is always active on the desktop as well as in game), I start Overwatch or Assassin's Creed Odyssey and between the moment I switch from the desktop to the game, I have a blinking of one second. Out of curiosity, I did the test again by leaving the screen menu on the screen to see what was going on and then I see that the screen goes from G-Sync to Normal (as if G-Sync was cutting itself off) then returns to G-Sync mode. So I'm on the desktop in G-Sync -> For a second, the screen is black and blinking, I'm in Normal mode -> The next second, I'm in my game menu, which has blinked again to go back to G-Sync mode. The same thing happens when I return to my Desktop: I quit the game in G-Sync -> Black screen in Normal mode -> Return to Desktop that flashes and returns to G-Sync mode.

 My question is very simple: Why do I have these two problems?

 Is it a Nvidia driver problem (I am up to date and I do a clean installation every time)? Is it the G-Sync chip on my display that became defective after two years of good service?

 In advance, I thank you for the help you can give me. I really hope to put an end to all this.

It's the screen resolution change that happens when you switch from one to the other. I hope that NVIDIA can eventually fix it, but it's just as likely it'll be the game developers that will come up with a workaround. Just as when you (for instance) change from a 4K desktop to a 1080P game, you get a bit of blank while everything changes to the new settings. Pretty much any monitor will give you that little bit of blip during the change.
