[SOLVED] What happens if I disable the dedicated GPU, but the CPU doesn't have an integrated GPU ?

[Eddie Mitza]

This may be a weird question, so let me explain what this is about. Right now, I have an older monitor that sometimes my dedicated GPU does not recognize (usually after restarting or turning the monitor off and on). To fix this problem, I have to switch to my tv screen, go to Device manager and then disable and enable the Display adapter multiple times until the dedicated GPU sees my PC monitor again. The thing is, on my current processor, I have an integrated GPU present, I guess that's why I can still see the tv screen when I disable the Display adapter, but I'm planning on buying an intel KF processor tomorrow which doesn't have an iGPU.

Now, the question is: Would I still be able to use that fix if I won't have an iGPU or my pc won't be able to see any screen after I disable the display adapter, and I would be stuck?

Thanks

Is the TV connected to the GPU or to the motherboard?
Also if it is connected with HDMI try a new HDMI cable since they often develop issues and lose connection.

The monitor is connected via a DVI/DVI cable to the GPU. The tv is connected via HDMI, but I can't remember for the life of me to which one, the GPU or MB, and I'm at work right now, so I can't check. But I remember the HDMI cable being connected in a horizontal position, so it must be connected to the GPU. Which, now, made me realize that both screens are connected to the GPU and none of them to the iGPU. So the fix should work still, I guess? I'm confused.

press win +ctrl + shift+ B, that will restart GPU driver, its basicly same as going into device manager and disabling/enabling display adapter there

That's extremely useful, thanks a lot.

I've checked back home and both the PC monitor and the TV are connected to the dedicated GPU, so I guess there shouldn't be any problems.

Your situation is why one should not pinch pennies and buy a KF processor without integrated graphics.

I've pressed the keys and now it won't see the monitor at all, even after doing the fix the way I used to do it before.....

EDIT: I had to roll back the driver for it to start working again.
