No. You cannot change the resolution on any MobilePro Desktops. The VGA out is also fixed and you cannot change the external resolution. Only the MobilePro 770 and MobilePro 800 allow you to change the resolution on the VGA Output.

Are you using a vga cable or hdmi? As for a solution try right clicking e desktop then click screen resolution if using windows vista/7 then select the monitor from the drop down menu and select it as the main monitor or secondary up to you and click apply. If nothing happens change the resolution of the external one to the lowest and hit apply. Hope this helps.

My Windows XP is connected to my Epson Powerlite S3, but the screen is blue with the words Source: Computer (Auto) No Signal on it. When I click "Help" on the projector, it takes me to a screen...

'No signal' and 'unsupported signal' messages mean 1 of 2 things, either the VGA output is off(laptop) or the display resolution is set too high(laptop and desktop). Assuming the VGA cable you are using is good, try this:

Desktop: hook the computer back up too your computer monitor & set the computer to the basic VGA resolution. For windows XP, right click a blank area on the desktop, click 'properties' on the dropdown menu, click settings. Write down the numbers in the 'screen resolution' and 'color quality' boxes!

Drag the 'screen resolution' all the way down to then 'less' side. Then change the 'color quality' to the lowest setting. Click apply, then answer yes (the display will look UGLY - don't worry!!) Now connect your computer back to your projector. If it works, then the resolution you use on your desktop monitor is not supported on your projector. Experiment with different resolutions to see which one looks best on your projector. You will need to change the settings each time you switch monitor to projector.

Laptop: by default the VGA connector on your laptop is off. To turn it on, look for a blue symbol on one of your function (F1, F2, F3...) keys. It looks like an old TV with a line on both sides 'O' (F4 on HP) Press & hold the blue button (on the lower left of the keyboard, usually to the left of control ) and tap the bleu button you just found. Let go & give you're a computer a few seconds to change over. If the laptop screen goes blank, you found the correct button! The display image should now be visible. Repeat this 1 to 2 times to change it back to laptop display.

If you did not see the display on the projector, 2 other issues are possible. First, verify that the VGA output on the laptop is working - connect the laptop to a regular computer monitor & change the display resolution to the lowest settings (see desktop above), then try it again on the projector. If you cannot get an image on a computer monitor, your laptop settings may need to be adjusted in the same dialogue box as the settings. Monitor #1 is the laptop display, Monitor #2 is the external output.
Happy viewing :)

I connected my laptop to my LCD TV using VGA cable. I changed the mode to VGA external monitor. Image/video appear perfectly fine during start up. but right after windows logged in for like 5 second the...

Easy way:
Press and hold Fn key, and then look at the F1-F10 keys.. Most likely it is F7, and has a picture like a computer screen.
So, press and hold Fn key, and then press F7 (or whatever key it is for your laptop). This will change your "presentation" settings, and thus switch back and forth from laptop screen, laptop screen + external screen (TV), just external screen (TV).

If this doesn't work as you expect, just try:

Instructions for Windows XP:

Open the Display Properties window by:
Start -> Run -> %windir%\system32\control.exe desk.cpl,@0,3
(this is the same window where you can change screen resolution).

There you will see two or more "screens", labeled: 1, 2, 3.

Click on "1", and you'll see:

[X] Use this device as the primary monitor
[X[ Extent Windows desktop onto this monitor

Click on "2", this is your TV.. Mark

[ ]
[X] Extent Windows desktop onto this monitor

Then change the resolution to 800x600.
Click Apply

=> now your TV should start showing you a picture.
You can move your mouse between the laptop screen and the TV screen.

If you want just the TV, you can make "2" to be your primary monitor, by clicking on [X] Use this device as the primary monitor.

Since your laptop's display has a problem, that could indicate trouble elsewhere in the computer that is preventing you from adjusting your resolution properly. In fact, a shrunken display points more to a problem in the video processing, not in the display itself.

No. However, you can change the VGA Out from "Display the same image with LCD (640 x 240)" to 800 x 600 or 640 x 480.
