Display Output: Invalid format

[ALPHAMAXIMA]

So, i just messed up my gpu driver. what i did is changing the display resolution in amd ccc in display properties section to 1080p from 768p because i just curious, after i clicked the apply button my screen goes blank and showing invalid format.

Good thing i'm using APU so i can still post this thread.

I'm using AMD HD 7750 and AMD A4-5300.

And 14.12 Omega as my driver.

What i did is,

Change resolution -> blank (invalid format) -> switch to APU -> install APU driver -> uninstall APU driver (cuz i thought it will fixed it) -> switch back to gpu -> blank (invalid format) -> restart -> boot to safe mode -> try to uninstall gpu driver (but i cant) -> try to re install gpu driver (but i cant) -> switch back to APU -> post this thread

so please help me fix this

sorry for my bad english

When you set a wrong resolution, you are prompted afterward if the resolution was set correctly. If you don't answer Yes within a time limit (usually 30sec), it reverts back.

Anyway, Use your GPU, and go in Safe Mode. From there uninstall your graphics card drivers, and restart the system to go in normal Windows.

Once done, install the latest drivers.
