I have a gaming laptop with both a dedicated GPU (Nvidia GeForce GTX 1070) and integrated graphics (Intel HD Graphics 530). After 4 years, my GTX 1070 has finally started to fail. It crashes when running games, opening GPU-intensive apps, and sometimes even when viewing the little spinning 3D logo in the Nvidia Control Panel. The problem is significantly worse when running my laptop in G-Sync mode (with the integrated card disabled) where I can't even log in to Windows before the GPU crashes, but also happens in Optimus mode as soon as I run any software that needs the Nvidia GPU.
Because of this, I had decided to disable my GTX 1070 via the Device Manager and make sure that only the integrated graphics are used to run apps. That has stopped all crashing but makes my laptop useless for all gaming except really old games. There is another problem, however. I can only connect my laptop to my TV if my GTX 1070 is enabled because the HDMI port is connected to the Nvidia card, which also means that in TV mode all my apps run on the Nvidia card by default. Interestingly, my GPU doesn't crash when my TV is connected, but it does as soon as I run any app that isn't extremely lightweight (such as a video player). My question is: Is there any way that I can leave the Nvidia card enabled so that I can use my TV as a monitor, but prevent it from running apps (and Windows) and instead make the integrated graphics run everything?
