Arc A770 - Losing video output

[boazvdw]

Hi,

My ARC A770 sometimes loses video output when changing to fullscreen. For example while I'm playing a game (rocket league in my instance, but did notice it on other games too) and press alt+tab to switch out of rocket league's fullscreen window and then try to alt+tab back in to rocket league my video output will be lost.

I heard this might be caused by using HDMI to my monitor instead of displayport cables. Unfortunetly I don't have any displayports available since I'm using a TV.

My setup:

Mobo: Asus Hero VIII
GPU: Arc A770
CPU: Ryzen 5600X
RAM: 32GB 3200MHz
Re-Bar: Enabled

PC HDMI OUT -> TV HDMI IN

Hello boazvdw

Thank you for posting on the Intel Communities. I am sorry to hear that you are experiencing issues when changing fullscreen mode with your Intel® Arc™ A770 Graphic. We would like to gather the following information to assist you with this issue:

• What is your TV make and model?
• Is pressing the alt+tab buttons when playing a game the only way to trigger this issue or does it happen to you in different scenarios?
• Have you tried different HDMI cables?
• Are you using any type of video adapters or dongles?
• Create a log file with the Intel® System Support Utility and attach it.

Hi Hugo,

Apologies for my late reply. My TV is a Samsung UE50RU7172U (4k 60hz). The issue is mostly happening when alt+tabbing but might also happen after a reboot (most of the time when it happens after reboot it'll take a minute or something until it starts to display output, unless I take out the HDMI and replug it). I have also tried different cables already but without success unfortunatly. Please reach out to me if more information is needed.

Kind regards,

Boaz
