i wonder why other games like test drive unlimited or bioshock are running perfect with 1920x1080, while other games like BF2 only reach 1024x768.
i really dont know where to look for a better driver.
the device is a philips 42 PF 7641 D. maybe one of you guys can help me!
As I said previously, could just be some of those games don't natively support that res. I'm pretty sure BF2 doesn't from the threads about fixing it, I don't have it myself.
As for a driver, if it detected that wrong, you could either use powerstrip to generate one based on what the monitor tells powerstrip, or simply change it to the default 'plug and play' driver.
To do that you go to device manager (quick way is to type devmgmt.msc from start->run). Under monitors you should see something, double click the philips 105 you say it detected. Pick upgrade/update driver. All the way trough pick something like 'do not search, I will pick' up till you're at a white box with a couple models listed. Uncheck the 'show compatible devices' if you don't see 'plug and play monitor' then under microsoft from the company lists pick 'plug and play monitor' and finish the dialog with it. It should give it a driver that'll ask the monitor/tv what it can/can't show and should get 1080 functionning properly.
If some games already work at 1080p though, I'd say it's a problem with individual game resolution support, did you try the UT2004 demo?
