Fix for black screen/no signal

Easy Fix for Black Screen/No Signal after Dedicated GPU Driver Install, OS Windows 10

The problem (at least in my case) was the Windows 10 default settings for my monitor/TV were way too high; above 3000 X 3000 and a scaling setting of 300% this
did work with the Basic Driver

Step 1: You need to reboot into your on board GPU or into safe mode

Step 2: Go to the search panel and type in Display Settings (Bottom left of screen) you will be given a list click on the top item which is Display Setting and it will take you where you can alter the setting

Step 3: Change to what better suits your monitor e.g. 1862 X 1048 or may be even lower at 100% (HD TV) You may need to uninstall the Dedicated GPU driver and reinstall it.

Hope this is of help

PC boots up but monitor shows 'no signal' and keyboard not working.

Thanks for your answer, however i have checked all cables and connections and these are fine (work with other pc). Re step 2 - i cannot boot to safe mode as there is no monitor signal so i cannot see anything except a black screen.

how can i boot my PC to safe mode if i cannot see anything?

I can't change the signal resolution either as no monitor!!
