I have weird problem with my laptop (Sony Vaio S11X9E/B) - CPU: i3-330M. After clean Windows 7 64bit Ultimate install, there´s a problem with hardware acceleration, which menas that computer is slower and even Solitare is glitchy and pixelated, and resolution of display. Display has 1366x768, but I can set max 1024x768. After some research fo drivers I installed the newest one from the official website of Intel. Then I restarted the laptop and the problems with resolution and hardware acceleration were gone. Great, BUT.... Now, I have very low brightness of my display. Everything is set to max performance and 100% and still, it is max 20% of the brightness. The functional key to set brighntess doesnt work (only works manually set in power options), but volume change works, strange. So I restored default drivers and brightness is ok again, but my resolution is back on 1024x768 and hardware acceleration is not working again. Any solution?
