Many games turn my dual screens black then freeze - help!
« on: March 16, 2013, 05:18:50 PM »
For months I've experienced this issue and never found an answer: so time to ask the DC community!

When many games try to go fullscreen both of my dual screens go black and the system freezes.

I can't hit escape, alt+tab, win+tab, ctrl+alt+del, win+pause/break, win+d

The only way to get out of this situation is to hit the power or reset button and reboot.

A few examples…

Games that run just fine
All games in my Steam library
Batman Arkham Asylum
Civ V
Perspective

Games that black screen
Flight Control HD
Gatling Gears
OIO
Qrth-Phyl
Master of Alchemy
Super Hexagon

I can see no connection between those games that work and those that don't.
.
One way to get around the issue is to run offending games in a window, and if they don't offer that option to run them in a sandbox (such as the Comodo Firewall sandbox or SandIE) which forces them into a window.

Gfx Driver: Catalyst 13.1
Gfx Card: Radeon HD5770
Screen Res: 1280x1024 both screens.
OS: Win7 x64

Does anyone have any thoughts about what is going on? The situation is driving me mad!

Thanks

Ah-ha! I may have found the answer myself... seems to be the Defense+ component of Comodo Firewall causing the problem - it is asking me to create a rule for the new game I am running, but the dialogue box is trapped behind the fullscreen application with no way to retrieve it!

And just discovered that Comodo Firewall does contain a manually enabled Game Mode that solves this issue, though I've not discovered HOW it solves the issue!

  If your playing these games offline, you can RMC on Comodo Firewall and set Sandbox Security Level and Defense + Security levels to Disable, and Firewall Security Level to Block All, and then exit Comodo Firewall.  The front-end of Comodo will exit but will keep a portion of itself running in the background to block all incoming and outgoing transmissions.  You can now disable your anti-virus since the internet is blocked.  Whenever your done gaming, re-enable your anti-virus, run Comodo Firewall again and change the Sandbox, Defense and Firewall Security Level back to it's original settings.  Now your ready to surf again.  If you have a Network not working error of any kind, just RMC and select "Repair" and it will refresh your network.  This is the best way to play graphic/cpu intensive offline games and give yourself more RAM to work with as well.
