Hey,
Hope you guys can help me out... I'm banking on the tech geniuses here to be able to answer my question.
A couple of days ago, I flashed the A13 Bios to my Dell XPS 1645 which has the Radeon Mobile HD4670 graphics subsystem. My set-up uses a 20" external monitor plugged into the VGA output as my main monitor - and the built-in 17" screen on the portable as a secondary monitor.
Since flashing the bios, when I play games, the game will play really well for 3 to 10 minutes, then I get a sudden black screen and the computer powers immediately down. These are mostly MMO games and the issue does happen with all games tried so far.
I've been through a day of various testing and updates etc. with Dell support and their final suggestion is that it's because the portable's screen takes a digital output and I'm playing the game on an extended desktop to a screen on an analogue output.
Their opinion is that extending through VGA over-stresses the graphics sub-system and that the extra demand made by the games pushes it over the edge. They suggest that the old bios used to allow this - but that the new bios has closed out this option... thought it can take 10 minutes before the crash happens.
This all sounds a bit fishy to me, so I thought I'd ask you guys whether there might be some technical sense behind this idea. What do you think?
