First, what kind of cable did you use? HDMI? DVI? VGA/DSUB?
Second, try a setting in the TV. Look for terms like 'overscan' , 'pixel perfect', '1:1', or similar. Usually under the HDMI settings for that input.
If it doesn't help, and there is no "auto adjust" for vga, then:
Third, look for AMD settings in your pc, navigate to Display or TV settings, and check scaling options: either center of full panel.
Once you try both of these, if they don't fix your problem - find Overscan / Underscan settings and use the slider to fix the screen size.
Thank you for your response.
I am using a HDMI cable, I have not altered the TV settings at all from the time that it was the correct resolution, before installing AMD Radeon Settings, besides I cannot get these options on my TV. Tt's something to do with the program itself that's altering my resolution I have tried both of the options you suggested, neither work...
