Hi All,
Can't help tinkering with my NX7000 - 6 years now is it? Blimey!
Anyway, the easiest way to get native resolution in W7 is as follows:
1. Install W7;
2. Download the latest XP drivers from HP (at this time, for me it's sp30204.exe);
3. Run the .exe (which will fail - note the folder it installs in, again for me it's under C:\swsetup\SP30204)*;
4. Go to Device Manager;
5. Right-click and "update driver software" under "Display adapters";
6. "Browse my computer";
7. Point to the relevant folder;
8. Full 1680x1050 goodness and "Mobility Radeon 9200" correctly identified.
I haven't tried external displays - feel free to give it a go and report back.
Quite why this hasn't been spelled out before I don't know - such a simple task and it took me ages to figure out. Deliberately cryptic or incomplete answers should mean an internet ban. For a couple days maybe.
*UPDATE: the latest HP drivers don't seem to like hibernate, sleep or full screen flash (Youtube, 4OD, iPlayer). I suggest downloading this driver pack from Asus
ftp://ftp.asus.com.tw/Pub/asus/nb/A4D/VGA_XP_2K_060102.zip, unzip it to somewhere sensible and go to point 4 above. It's a newer driver (2006) which seems to have more recent Vista (and 7) compatibility - everything (other than Aero) seems to work. Enjoy!
