I don't understand how a video driver that was not certified for 8.1 but ran okay (much. FYI I had a look at upgrading (changing) the graphics card for. The one linked below is from the UK support page for the Inspiron 6400.

Upgrading my Dell E1505 Inspiron laptop to Windows 10. Upgrade check said the ATI Catalyst would have to be reinstalled; not a problem.

Upgrade and activation went okay. Win10 x32 with 2MB RAM and SSD. With one exception, the Dell Vista device drivers have worked fine (touchpad, media card reader, modem, network, Bluetooth, audio, etc). The exception is the video driver for an ATI Mobility Radeon X1300.

The default 'Microsoft Basic Display Adapter' was installed. The resolution with this driver is wrong, it is 1024x768. No option to change it (except down to 800x600). The display is actually 1280x800, so as a result everything is stretched wrong.

I finally did find a driver that would install and let me set the correct resolution, 'ATI Mobility Radeon X1300 (Microsoft Corporation - WDDM)' dated 8/25/2006, version 7.14.10.8333.

The problem with this driver is that every time I mouse over text in the Start Menu or text in the tiles, the text disappears. The background/highlighting of the selected item is still visible (a lighter gray on a black background) as I move the mouse pointer up and down, but the text is gone. Oddly, the first time I open the Start Menu after installing the new driver, it works fine. But starting with the second time the text vanishes. And it doesn't come back until I restart, or reinstall the Microsoft Basic Display Adapter. Text in applications and desktop icons seems unaffected.

Thinking it was just an upgrade quirk, I re-did the upgrade, this time a clean install and I had Win10 Setup format the drive first. Same result.

I've tried installing a bunch of other versions but I get the message 'The driver selected for this device does not support this version of Windows.'

I've also installed the DX9 runtimes but that didn't help.

Nor did today's (Aug. 10) Windows 10 major update help.

I should add that right after POST when just the blue window is showing, the circle-of-dots is correctly round even with the Basic Display Adapter. It's not until the start screen (with time and date) that the effect of the wrong resolution appears (horizontally stretched).

Is there a setting somewhere I am missing? Any help would be appreciated.
