Hi I have an Acer Extensa 5630 laptop with the Intel Mobile 4 Series Express Chipset graphics.
The optimum resolution for this latop is 1280 x 800 and everything was fine until I attached an external monitor to the laptop. Which the Intel chipset is supposed to handle fine ( and did until i removed the external screen again from the laptop)
Now ever since when the laptop is booted (minus the external monitor) the display resolution changes from 1280x800 down to 1024 x768 and I have to go into the driver config and set it back up to 1280 again. When it is booting you can see initially it does show in the 1280 resolution however as windows is finallising its startup the resolution changes down as you watch it.
I have tried all the settings, uninstalled and reinstalled the intel drivers and this effect continues.
If however I attach the external monitor then the resolution stays at 1280 on the laptop display and does not drop down to 1024. But as soon as the external monitor is removed then I am back to the problem again.
It looks as if the intel driver is now defaulting to a lower resolution at startup but I cannot see how I can get the settings to stick at the desired(and correct resolution of 1280)
Any help is resolving this would be much appreciated.
