Windows 10 Inspiron 1545 (2008) ATI Radeon hd 4300 in 1366x768 resolution

The standard Windows 10 drivers will not support the 1366x768 resolution of the ATI 4300 video on the Inspiron 1545.  The best you'll get is 1024x768.  The same goes for the most recent ATI drivers.  I have found that you need to go back to the January 2015 driver (8.970.100.9001) to get 1366x768 to work.  It does work, however getting hold of the driver isn't easy.

Here is an extract from the AMD driver site:
