Help needed to alter Video Driver Refresh Rate
ok.. I have a commell 677 motherboard and Cartft posted some intel drivers which you can use to get true 800 x 480. The only problem is my xenarc tft doesnt like the refresh rate there running (defaults to 600 x 480) So I had a quick look and I am thinking I might be able to change this here... I have also attached the full file just incase

The actual lines that control the timing parameters are these:

Code:
HKR, Config\1\Port\5\Dtd\1    ,    PixelClock, %REG_DWORD%, 38550
HKR, Config\1\Port\5\Dtd\1    ,    HorzActive, %REG_DWORD%, 800       
HKR, Config\1\Port\5\Dtd\1    ,      HorzSync, %REG_DWORD%, 40        
HKR, Config\1\Port\5\Dtd\1    , HorzSyncPulse, %REG_DWORD%, 80         
HKR, Config\1\Port\5\Dtd\1    ,     HorzBlank, %REG_DWORD%, 232        
HKR, Config\1\Port\5\Dtd\1    ,    VertActive, %REG_DWORD%, 480       
HKR, Config\1\Port\5\Dtd\1    ,      VertSync, %REG_DWORD%, 61        
HKR, Config\1\Port\5\Dtd\1    , VertSyncPulse, %REG_DWORD%, 3         
HKR, Config\1\Port\5\Dtd\1    ,     VertBlank, %REG_DWORD%, 142        
HKR, Config\1\Port\5\Dtd\1    ,         Flags, %REG_DWORD%, 0


You can adjust the values in the INF file to the above numbers, which should do the trick.


Or, just download this driver package instead, which I built yesterday for 800x480 on Intel 945GM based onboard graphics:

http://moschini.org/945GM-800x480.zip


I've been able to confirm that the driver package works, and they were using a 7" Xenarc too.

The driver package I posted should work perfectly.

Apologies for bringing a three month old thread back to life, but if I am unable to change refresh rates using Windows, is my last recourse changing registry information such as this? I have a VIA M10000 motherboard with an integrated graphics processor (VIA/S3G UniChrome), and it only seems to allow a refresh rate of 60Hz, whereas I need to change mine to 75Hz to solve a different issue.

I have yet to get the proper drivers. I attempted to install new drivers this morning before work, but it was not compatible with my chipset. I will have to actually find the drivers while I am in the car, so that I can use some online detection utilities. I am also going to try using powerstrip, but must do some research first.
