Hey all,

Thank you for your time.

I have a HP 260 G2 with a Intel HD Graphics 520.
I have a problem when i connect this computer to a 50" TV with HDMI cable. After 20 minutes, the computer just freezes and the screen becomes either black, blue or green.
The computer is 18 months old.
When i connect this computer to a 22" computer monitor, everything is fine and i can run a Graphic stresstest for hours without a problem.

Eventlog does not say anything usefull, only the fault of me shutting it down (unexpected shutdown).

I have tried different drivers (Microsofts, HP's and Intels), different TV's and different power supply cables.

I am at a loss and would love to hear your insight.

Thank you in advance.

Resolution on TV was the same as computer monitor: 1920*1080.
I dont know the CPU temp, the fans are spinning fine and the case (SFF) is not hot, just a bit warm.
