I've decided to test Windows 7 on my cheap old laptop.
The machine in question is Fujitsu Siemens Esprimo Mobile V5535 based on SiS M672 chipset (with integrated graphics).
Installation went pretty smooth and without any problems.
However when I've started to test the new OS I've found an annoying issue: getting extended desktop on my external screen (mainly used for watching movies).
I've tested different available drivers (uvga5 5.20 and 5.12 from SiS and drivers that came from Microsoft via Windows Update) but I couldn't get it working.
The result I had was that when I was turning extended desktop only secondary screen was working and primary was blank (turned off). Clone was working without any problems, switching between screens also.
And the most annoying thing was that I knew it can work like that because it was working under XP on same machine.
Finally after a lot of Googling I've found one post from "amirimon" that helped me to fix things:
Windows 7 WITH Extended dektop - Esprimo V5515The latest driver from SiS at the moment (uvga5 5.20) will give you driver version 7.14.10.5200 but on
Microsoft Update Catalog website you can find 7.14.10.5210 which will fix this annoyance.
There are still few things to fix in next release of those drivers (I have to use same screen resolution on external screen as main LCD or screen goes blank) but at least it's working and there is hope they will fix it in next releases.
Edit:
New drivers do the trick.
UniVGA 5.22 (7.14.10.5220)
