vga cable - screen resolution
I would appreciation some help or pointing me to where I can get help.
Running 64bit 7 professional on Dell lattitude 6420 and an external magnovox display thorugh the docking station. When I restart the computer or wake from sleep, the monitor flickers for about 5 minutes until it settles down, but evenually settles down and displays at 1440x900, the monitors native resolution. When I go to display settings, windows 7 recognizes the "Magnovox TV" as the display.
I suspected somthing bad with the VGA cable and changed to a different, newer, one. When I do this, I do not get the lcd flicker, but I do not have the option to display in 1440x900 and when I go to display settings it recongizes only a "Generic npnp monitor."
Why, when I switch cables does it no longer recognize the monitor brand and not give me the display resolution I want? I have resarted the compuer a bunch of times, tried unconnecting and reconnecting. Also, I have looked at the nvidia settings to create a custom resolution and 1440x900 resolution fails the test using BOTH cables. When I switch the cable back it agian recongizes the magnovox lcd and gives me the 1440x900 option.
Thanks in advance for any tips.
