I have installed a Radeon HD 5450 graphics card in my Dell Opitplex 745 SFF PC but cannot get the card to retain my chosen settings, 1920x1080.
It is connected to my Samsung TV via the HDMI port.
Whenever I reboot the PC the resolution is back at 800x480 again.
The OS is Windows XP Pro 32 bit which I have re-installed but to no effect. It still reverts back to 800x480.
I have installed Ubuntu and Windows Vista by way of a test on this same PC and the resolution is stored correctly, so it just seems to be a problem with XP.
Anyone got any thoughts what could be causing this 'amnesia'?
