Connecting tv via hdmi result in a not correct visualization

on the internet you can find a lot of similar problems by digiting "catalyst hdmi fuzzy blurry".

the problem is when i connect the tv as a secondary monitor via hdmi i cant get the correct 1:1 mapping over the screen, the image is larger than the panel and if i use ccc scaling option i cant fill correctly the screen.
the image expecially the text is blurry.
the tv recognize the signal in a different way, on the tv i can adjust some video options like sharpness and fills the screen with the option to fill screen, all these video option help me a bit with blurry text, but there should be no.

on the tv i have 4 port hdmi, only one of them is called 1(DVI) and it's for connecting a pc via dvi2hdmi adaptor. that port works fine but it's already in use by another pc. the remaining 3 "only hdmi" ports do not works as i expect.

can somone help me please?

Unfortunately, televisions make poor monitors. It has to do with the native resolution of the TV itself, which is entirely different than what the computer wants to provide.

If you can get away with it, perhaps you need to find some sort of video switch for the one good input for the TV.

hdtv resolution works great in the 1st hdmi port called 1(DVI), on the others 3 ports i need to adjust video settings.

by the way, no problem it seems no one know what really is the problem.
