I have a Vizio M220VA tv to which I connect my T20 via the display Port. I never get a screen showing on the TV, but the laptop screen oscillates between a black/blank screen and the normal desktop. I have verified the T520 works when hooked to a different TV and that the TV works when hooked to a different laptop.
My graphics adapter shows as a " Intel HD Graphic Family.

Just a few questions to help us understand the situation better:
1. The other laptop you mentioned, is it also connected to the TV via displayport?
2. Are all your video/display drivers on the T520 the most up to date ones?
This may help others or myself in figuring out a possible solution.

Yes, the second laptop does connect via the display port. And yes I have updated the drivers. And the display port adapter/converter and HDMI cable was the same on both.
