How old is your monitor. Mine did that and it just quit working one day, I had to buy a new one Hopefully, yours is something else. Is it blank while it is booting up, or has it been on and then goes dark?

If you have two separate computers for different purposes, such as personal and work use, you may find it convenient and necessary to connect both to a single monitor. Many monitors have dual inputs, making such a connection simple. However, you might need a keyboard, video and monitor switch to accomplish this task if the monitor lacks a second input. Dual Inputs
Step 1 Examine the back of your monitor for the presence of dual video inputs, such as a single VGA and DVI or HDMI output.
Step 2 Connect the VGA cable to one computer. Plug the other end of the cable to the matching input on the monitor. Rotate the retaining screws until tight at both ends of the cable.
Step 3 Plug the DVI or HDMI cable into the back of the second computer. Insert the other end into the monitor's digital video input. Screw down the retaining screws if you're using DVI.
Using a KVM Switch
Step 1 Ensure both computers are turned off. Place the KVM switch on your desk where it is within convenient reach.
Step 2 Locate the video output port on the back of the KVM switch. Plug a VGA cable into this port. Plug the other end of the VGA cable into the monitor.
Step 3 Plug the VGA monitor outputs from each computer into the inputs on the back of the KVM switch. Tighten the retaining screws down for each connected VGA cable on the computers and the KVM switch.
Step 4 Plug the keyboard and mouse cables into their respective outputs on the KVM switch. Plug each set of keyboard and mouse cables from their ports on each computer into the matching inputs on the KVM switch. Plug each cable in sequentially to avoid mixing them up between machines.
Step 5 Double-check that the mouse, keyboard and monitor cables leading from each computer all correspond to the right machine. Plug the KVM switch's power cord into a nearby AC outlet or power strip.
Step 6 Turn the computers and monitor on to verify the connections are correct.

Required Items

• VGA cable
• DVI or HDMI cable
• KVM switch
• Power strip (optional)

If your computer has an HDMI or DVI external monitor plug, you can use a cable to plug into an available HDMI plug on the TV and change the input. Your computer image will show on the tv as well. If your tv came with a VGA plug (smaller and would also be named PC) you can plug into this and change the input on the tv. If your computer only has a VGA plug and the tv does not have a VGA, the picture will look stretched.

VGA no signal means "no signal" from the computer on the VGA (blue plug) cable... ...if the computer works check the cord for loose connection or get a new cord...if the computer is hooked to the digital cable (DVI/white plug)...set the signal source on the monitor to digital...

Used the VGA cable came with ur computer monitor,used that VGA cable plug in VGA input it the tv and plug it other end to the computer video card.Used ur tv remote look for a input button pushes look for the mode computer signal in the tv like input 1,2,3..so on.

You'll need:
•VGA cable
•S-Video Audio to 3 RCA Type Adapter Cable
•HDMI cable
•DVI cable
Check the connection options on your TV. If your TV has a VGA connection slot, plug the TV into the computer with a VGA cordlike a computer monitor. Connect one end of the VGA cable to the back of the computer and the other end to the TV. Switch between normal TV viewing to displaying your computer on your TV by selecting the proper mode from the remote control, some remotes will mark the proper mode as "VGA" while others will label it "Computer" or "PC."
Check the back of your computer to see if you have an S cable slot. Connect S cable portion of the S-Video Audio to 3 RCA Type Adapter Cable to the computer and plug in the green audio plug to the audio port of the PC. Plug the red white and yellow RCA cables into the matching colors of the RCA slots on the TV. With this method you will need to switch modes from TV to video.
Check the back of the computer and TV for either DVI or HDMI slots. The slots on your computer must match, you cannot connect a DVI to a HDMI. Plug one end of the corresponding cable into the the back of the TV and the other end into the computer. Choose the correct program mode, HDMI or DVI, from the remote to view the computer from the TV.

This may be more of a computer problem then a TV. If I'm right, here's the solution:
Computers don't always recognize video output without a little assistance. You should plug your computer back into your normal computer screen AND your TV at the same time. I guess that only works if your computer has two VGA outputs, but most desktop PCs do. Anyways, once that's done, open up your computers display settings and try to get it to recognize the TV from there (be sure the TV is on the correct input while you do this).
If you need more help with the computer side of this, let me know. Also list your computer's model and your operating system.

I ahve to assume that your new monitor has a DVI connection that looks like this...
Your Optiplex probably has a VGA connection that look like this...

You'll need a VGA to DVI adapter (available at electronics stores or online everywhere.

Or, to take advantage of the higher quality resolution of your new monitor, you might consider buying and installing a new graphics card with a VGA & DVI adapter so you can plug it in directly and get higher res.

You will not benefit from the DVI input unless you have DVI output on your computer. The great advantage of DVI is that the picture is transferred in digital form all the way from your computer to the individual pixels on the monitor. If you only have VGA output on your computer then you will never get a better picture than by using a good quality VGA cable to link that to the VGA input on your monitor.

The DVI plug is designed to carry both digital and analogue (VGA) signals on the various pins, so "adaptors" exist to allow a VGA monitor to attach to a DVI output on a computer. Monitors may also support VGA input from their corresponding DVI input sockets, but the picture quality will never be better than by using a good VGA cable because it is still not using the digital capability of the DVI interface. What's more, because you may need more adaptors and thinner conductors in the cable, you will probably achieve a marginally poorer picture than with VGA to VGA.

When you next buy a PC or a new video card, get one with DVI to take advantage of your new monitor. In the meantime, your best bet is a quality VGA to VGA link.

Sorry that's not what you were wanting to hear, but I hope it will help you avoid further frustration.
