Got my laptop hooked up to a 42"plasma screen.Its rather blury.Do I have to adjust it through the computer

Question

to make this more clear?

Answer 1

Possibly, but more likely you would be stuck with the quality that you see since the video card embedded in your laptop would not be optimized for a screen that large.  In order to maximize space on the motherboard, most laptop manufacturers would only use video card specs required for a screen no larger than about 17".

Answer 2

Yes. If you have Windows right click on the desk top and go to properties, settings and try adjusting the screen resolution.

Answer 3

Most likely, you are using an S cable. This will only transfer SD. Your desktop will be virtually unreadable.

To get a good desktop on the TV, you need to use VGA, component, HDMI or DVI cables.
