Evo notebook external display problem

[Elliot Nesterman]

When I attach a projector to the external port of my EVO N610c notebook the display adapter makes both the lcd panel and the projector primary displays. This causes the video chip much confusion; the external display continually jiggles and flickers. I can set the advanced properties to make the projector the clone display, but the setting doesn't stick between boots. This is not a problem for me, but is a big issue for our corporate users during presentations. Does anyone know if there is a way to force the external monitor to be the clone and the nhotebook's screen to be the primary? Thanks.

To be XP compatible a PC has to support two displays. If it is not doing it very well then I would first upgrade the BIOS (Rompaq for Evo N610c System BIOS (68P4F ROM)
) and the video driver (Radeon M7 Video Driver)then get the System Enhancements Disk for Windows XP. These are all on

Then go to http://windowsupdate.microsoft.com and let them scan your system to see what else you need.

I can't tell from the online manuals whether yours has it or not but on my Armada there is a Fn key and if you hold it down and press the F4 function key (the notebook is in the docking station right now so I can't look at it I think it's the one with two interlocking rectangles on it) it will switch between the builtin screen and the external.

Thanks for the files, Ron. Yesterday I finally had the time to work on the notebook. I actually ran the restore CD and then applied all the patches i could find, including the ones in your post. it seems to be fine now.
Oh, Fn+F4 cycles the display on this machine also. The problem seems to have been the ATI drivers.
Thnaks again.
