EDID fix for AMD cards

Using a 37 inch lg hdtv. And my laptops video card is HD 8400 R3 series. I am failing the 4:4:4 picture test and my text is a bit blurred. Would like to know how to fix this. I've done it on NVidia cards before but I read that the options are in the amd drivers instead of having to hack it like on the NVidia side. I am using a HDMI to HDMI connection from the laptop to tv. Can anyone help? I'm on Windows 10 also.

Thanks guys!

I seem to recall some old tricks like labeling your PC input as PC on the TV. Also possibly using a dvi to hdmi cable for the hookup. Or a dvi cable + hdmi adapter.

Yea I remember those tricks. But I though there was an option in ATI's drivers to fix this without any other software hacks.
