I noticed yesterday that my T41P connected with the VGA output directly to my Sony 20" LCD gives a blurry picture quality when i compare to my other PC which has a Nividia card connected DVI-DVI to the monitor.

Is the analog video filter really so bad in the Thinkpads?

How do i solve the problem? should i buy a Thinkpad dock unit so i can output DVI-DVI?

What resolution is the LCD ? What resolution is your laptop set to ? Are they the same ? Are you using a good quality VGA cable ?

Resolutions don't match. Your external resolution is probably set to SXGA+ (1400 x 1050). Only a couple of vendors made monitors with that resolution, Sony was not one of them.

Change it to the native resolution of the display.

Of course i have it set native resolution of my external monitor and use a high quality cable.

Anyway it was no the answer to my question.

There's probably an "Auto adjust" button on the Sony monitor. Press it.
