Forcing a res for older plasma?

[Digital Viper-X-]

Is this possible? my brother has an older EDTV panasonic viera, and it only gives me 720x480 which isn't right, or 800x200 720p 1080p(the tv downscales it i guess but the text looks bad then)

is there a way to force the 840x480 or w/e the res is? he has a 780g mobo with an ATI HD3200 on board card going in via HDMI

What model is it and how is he connecting the pc to it?

HDMI, does it matter what model? i'll get it when i get to his place later, but i want to force it from the pc it doesnt show up as a resolution, it should be 480p

Many TVs only support a few resolutions through hdmi and will scale anything else. Depending on what model it is, you may be able to put it into a pc mode and turn the scaling off. Or if it has a pc input then that may have to be used instead.
