Hello !

i have a strange little problem with my recent computer on windows 10.

I have 3 screens connected (dvi, d-sub and hdmi) :

The hdmi one lose its signal and reset when i launch a video (with chrome, firefox or simply on desktop with VLC) in its zone.
That last approximately two secondes, the screen show "hdmi input" then works perfectly after that reset.
After that, it reset again when i close the tab with the active video.

If the video is on another of the three screens, no problem.

I tried to update my GPU drivers but it's till here.
I also updated absolutely all the drivers on my computer (to solve a BSOD problem, but it's ok now) and then the bios-uefi without any change regarding this very problem.

I have no clue where this problem come from and it's really annoying.
The only thing i know is that it's not the screen by itself. Switching between screens keep the problem on the one connected in hdmi.

Thank you :).

I have seen the same thing on many HDTVs when used on the HDMI port of a PC.  It's the CPU in the TV sensing the input, its mode and looking for the audio then loading the screen.  Not a problem.  Do the other display units flash too?

A little late, but i was in vacancy.

Well, it's good to know it's not a screen problem.
But, the switching is slow so it's really a big inconvenient. 

How to solve that ? I tried all the options i found on the screen itself but that changes nothing.
Using a hdmi to dvi cable maybe ? So the screen use its DVI input ?

Not many TVs have a DVI input.  Adding another stage (adapter) between the HDMI and the TV will only slow the process more.

in my case, it's not a tv, it's a screen with audio interface and speakers.
I can use its DVI input but my GPU last outpout (i have 3 screens) is hdmi so i will need a hdmi to dvi adapter.
I can buy one but without knowing if that will work :/.
