Mac Mini to 50 inch Plasma and Text Problems: SwitchResX can fix? Help

[legaleye3000]

I really don't know how to use it to fix my problem... I have a Mac Mini hooked up to my 50 inch Plasma. Its hooked up in the following way:

USB cord for sound hooked into this adapter. Then a minidisplay cord hooked into the adapter for display. Then on the other end of the adapter is a hdmi cord that goes into my tv.

Picture looks fine, but the text (such as on websites, and this text that I am writing) is sooooo small looking. If I zoom in (control+scroll), yes it does look bigger, but its such a pain. I heard SwitchResX might be able to help...

Any ideas? Thank you.

I got it (mostly working)

The size of the text is much better, etc. The only thing now is that the computer picture doesn't fully fit the screen. There is about a little more than an inch black border going around the desktop. I just need to "stretch" it somehow.

Any ideas on this? Thanks
