Over/Underscale

[yyq]

Hi there,  

I've been posting on a few other places but yet to get a reply that is able to help out with my problem.

 

So there is a very small (1cm) black outline on each of my monitors. (2 dual link DVI, 1 HDMI) .   
it looks like AMD over/under scaling is enable but it is in-fact set to 0% in Catalyst

 

From what i was able to discover it seems that there is only registry editing i can do to set over-scaling to 0% but i have not been able to locate what each post were talking about.

 

So what I'm looking for someone who is able to help out in removing all of these outlines. or able to point me in the correct direction.

 

Thanks,

Can you switch to the option off? There's an option for enabling or disabling GPU scaling in the Catalyst Control Center.

It is the result of an AMD underscan setting. Even if it is set to 0%, look for a way to actually disable the setting.

I have fiddled with GPU scaling.  It does not seem to affect it at all.

Reg edit seems to be the only way i've read to be able to do that. I have tried searching for the common answer of the question. Being "Resolution in 0000/0001 " and set all binary values to 0.   I have not been able to locate that in my reg.

Attempted to set hdtvdefaultunderscan to 0. But no avail.   

 

Cant seem to find any more ways to try and fix
