TV out Resolution

I have a Sony VAIO laptop model F-490. It has a NeoMagic MagicMedia 256XL+ video adaptor with the 4.12 drivers installed.

I am having a problem setting the TV out resolution above 640x480. I used to be able to set the TV-out resolution at 800x600 to watch my DVDs on TV. Now, however, after I installed the new drivers (4.12 instead of 4.11) the slider bar for External Display: TV is stuck on 640x480 and I cannot move it to anything else. The problem is that at 640x480 the DVD image is really bad.

Before this problem occurred, I used to set both the internal resolution and TV out resolution to 800x600 and watch my DVDs on TV. Now, I must set them both to 640x480 because the TV out resolution does not go above 640x480.

I have no problems with my internal display resolution. I am set to 16 bit color on my internal display. I can change my internal display resolution up to 1024x768. It's just that the TV out resolution cannot be set above 640x480, and I used to be able to get it up to 800x600.

I tried to remove my new driver, install standard VGA drivers, then reinstall my old driver, but that did not work. I tried looking for the driver settings in the various INI files but I could not find anything. I tried to find my way in the registry and found the TVSizeX and TVSizeY setting to be set at 640 and 480 respectively. So I changed them to 800, 600, but that too did not work, as once I refreshed the registry or booted the laptop the resolution changed back.

If you know how I can manipulate the TV out resolution, or if you had similar problems in the past and fixed them, please let me know. I know that there must be a way to do this, since I used to be able to set the TV out resolution at 800x600. By the way, my monitor driver is set to Laptop Display Panel (1024x768).

Thanks,

So, it worked under 4.11 & now under 4.12 it is broken. so far your attempts to re-stall 4.11 have been in vain.

I'd call NeoMagic - boardmaker - with the issue; there is a chance that the version that you installed wasn't intended for use with a TV out capibility [doesn't explain why is seems to stick]

Possibly I've seen Windiws::System::Inf::other

devices show that need to be reomved in order for the system to properly re-stall the 'proper' driver. removel of all of the associated keys for the video driver may also be necessary for proper function. :)
