i've recently had the same problem. Did some searching and the solution that worked for me was forcing the desired resolution outside the game. In your steam library right click portal 2 and click properties. Then click Launch Options and write these commands:

-w for width and -h for desired height, so in my case i left the launch options as:

-w 1366 -h 768
hope it helps
that helped thanks

I encountered the same problem. DefunK's solution fixed it for me, in that I could see the initial screen -- but I had to adjust the horizontal hold substantially, the screen was displaying way off to the left.

Quite bizarre...

Note: Change it depending on your screen resolution. If you had an old screen, for example, that was 640x480, you'd put -w 640 -h 480 in your launch options.
