SOURCE: DVI no input signal......VGA input active.

Are you running an additional Video card? Or are you using the built in one.
You might try cleaning the connector / plugs with acetone from finger polish remover or de=natured alcohol.
Never jam anything on a computer.
If its an add on card, remove it and reboot. Shut down and reinstall card and reboot.
keep me posted please,

SOURCE: my monitor will not work with the originally

Try this if you haven't already, UNPLUG THE MONITOR FROM THE WALL.
LEAVE UNPLUGGED FOR 5mins and PLUG IT BACK IN AT THE WALL.
Alternatively try another dvi cable could be a dodgy cable.

SOURCE: monitor shows VGA no input signal DVI no input

This sounds like a video card driver issue or the card it self. Make sure all cables are plugged in snug. Once done try to boot in to safe mode by restarting the computer and while it is starting keep on tapping key F8 and choose safe mode. If this works it is driver issue. If nothing happens it is the card it self. Might have to take it to a authorized repair shop. Hope this helps.

Which cords and/or plugs should I use inorder to connect a projector to a computer


if your desktop doesn't have a standard vga socket then you can get a dvi adapter that fits onto the end of a vga lead. you will still need a seperate cable for audio as a dvi connection only does video.

How do I fix the error no vga input signal no dvi input signal monitor going to sleep


Check if you VGA is properly settled in the PCI slot. Try to take it out, clean the slot for dust.
If that doesn't help, it is well possible that you VGA is not working any more.

No DVI video output from dell xps 210


It sounds like your video card has gone out. Is the VGA and DVI ports on the same video card? If so the card is probably bad.

How to use rca entertainment series 32 inch as pc monitor


Assuming that your RCA 32 inch tv has an HDMI or VGA input, all you need is the proper cable to connect the two units. If your computer has a VGA out (blue female connector) and so does your TV, you would need a male to male VGA cable. If your computer has a DVI out (white connector), you would need to purchase a DVI to HDMI cable. The combinations can me played around with depending on what connectors are on the back of the TV and what you have as an output for your PC.

How do you hook up the tv thru dvi out with a sony pcv-rs620g


There are several ways to do this. The two best are:

1. Get a DVI to HDMI cable. This will allow you to plug directly from your computers DVI to your TV's HDMI.

2. If your computer has an analog (rgb (vga) 15 pin) input, you can simply get a dvi to vga adapter and plug into that port.

Currently, I am using option 2 for my own use.

In the photo below, I point out the HDMI, RGB (VGA), and audio inputs. You must use the audio input but you have a choice of using the HDMI or RGB for video input from your PC. If you have the extra HDMI slots, I would use that. If not, the RGB is fine.
