Acer ka271 cycle trough input when alt-tab

[Jonathan_120]

Hi.
Whenever i alt-tab out of a game or even when i start one, my screen will go black and on the top right corner a series of icon will appear and show hdmi, dvi and vga plugs. Takes about 5 second between the alt-tab, then 5 sec between hdmi and dvi, then 10 sec between dvi and vga.

For example, when i start fallout 4, it cycle twice before i can see fallout splashscreen. When i alt-tab out, it does it once and again while alt-tabbing in.

Also, my second screen (a small and old lenovo) will turn black while this process goes on and usually come back faster then the Acer

I read somewhere about refresh rate causing it to cycle, but both screen are at 60hz.


I have an rx480 card.

It does it also when windows pop a dialog box like when i updated Skype, it ask if i allowed it to change something in my computer. It make my screen cycle trough all of it.
