Hello,
I just got a projector and when I connect it to a computer, the projector recognizes that a source is being used but displays a very dark blue screen (not the usual blue screen)... It’s a Sony VPL-EX4.
Thank you for your help.

Hello, here is my service overview if it can help you
Screen transfer from PC to video projector or TV
Turn on the TV or projector, the video connection will be VGA, S-video, composite (yellow RCA), or HDMI, depending on the device. Except for HDMI, an audio connection must be added
You can use an adapter from SCART to S-video, composite, and audio on older TVs
There are several ways:
Start with this simple way to do it on recent PCs running Windows 7 and 8: press the "Windows" key + "P" key and choose your option "Computer only, projector only" or duplicate, which is not useful here
Or another method:
On your PC, right-click on the desktop
Display settings
Click on "Show desktop only on 1" or "Show desktop only on 2"
Apply
The image will then project onto the projection screen and the computer screen will go black
Click on the projection screen or TV by moving the mouse over "Keep changes"
OK
Do the reverse operation to get the image back on the computer.
Or turn off the projector and the image will automatically return (after a few seconds) to the PC monitor
For audio, except in HDMI connection, use the audio output of your PC sound card to feed your TV or an amplifier
You need to align the display resolutions to the maximum of the least performant of the two screens
Or explain it this way:
1. VGA and DVI ports
2. To open Control Panel, click the Start button, then Control Panel.
3. In the search box, type "projector", then click "Connect to a projector."
(To use a keyboard shortcut instead of Control Panel, press the Windows key + P).
4. Select how you want to display the Desktop:
Computer only (this displays your Desktop only on your computer screen);
Duplicate (this displays your Desktop on your computer screen and on a projector);
Extend (this extends your Desktop from your computer screen to a projector);
Projector only (this displays your Desktop only on a projector
For a TV screen, it's the same method
"Donkeys change their minds, not fools"
Remember to mark your message as "resolved" if that's the case
