Black screen help
So, I just installed Portal 2 on my desktop computer, I'm using a 32 inches toshiba tv as a monitor (connected via DVI), and every time I try to run the game my tv goes black and tells me there's nothing connected (as if my pc wasn't on, or was disconnected) but I can hear the Portal 2 menu sound, and I can go through the menu with my keyboard, I just don't know why it isn't showing a thing, it's the only game I'm having this issue with, and if I minimize the game the tv stops showing the message and shows me my computer screen properly.. I have had Portal 2 installed on my laptop for almost a year now, and I've never had any issues whatsoever there (Inter Core i5 @ 2.30GHz, 4 GBs ram, Nvidia GeForce 410M - 512 mb, Windows 7 Home Premium 64-bit)

My computer:
Pentium(R) Dual-Core CPU E5200 @ 2.50GHz
4 GBs ram
Nvidia GeForce GT 220 - 1 GB
1.2 TB of available space on my hard-drive
Windows 7 Ultimate 64-bit

What you have to do is go into the options and click on keyboard. Then click on advanced. Then enable the developer console. Press ~ to open it. Then type this command while in -game:
mat_postprocess_enable 0. You will have to do this each time you want to play.
