My eMachines E19T5W 19" has DVI-D with HDCP Input

SOURCE: hdmi to dvi

This message may occur if the signal from the video adapter exceeds the scan range of the monitor (monitor not HD enabled).

The video adapter setting on PS3 for updating the screen (the refresh rate) is incompatible with the monitor.

SOURCE: THE MONITOR SONY SDM M81B HAVE HDCP??

A DVI to HDMI cable should work, I have the same monitor, but attached to an Xbox 360, if that doesn't work then buy a HDMI Cable and a HDMI (Female) to a DVI (Male) Adapter

Cheers

Not Good..
After you've checked that the video cable is connected properly, make sure that all the pins in the video cable plugs are straight and not broken off. Then test on another PC. Make sure your CMOS battery has not gone flat, as some PC's will fail to load basic drivers if CMOS memory is lost. The battery should show no less than 2.5v, if it's marked 3 volts when tested on a multimeter. If you can't test it, just buy a new one at the supermarket or hardware, usually around $4.00.
Next thing to try is your Video Card . If it is an on board one like most are now, there isn't anything you can do but try another card in an expansion slot or fit a new motherboard. At this point, I'm sad to say, you're better taking it to a PC shop where they will have a few things at their disposal to try.

SOURCE: plugged in my emachine LE1938 to my dell without the DVI cable, screen displays 'no signal'. Shouldn't the monitor work without the DVI cable?

The DVI cable transports the display signal from the video card to the monitor.

I think what Ron is asking is if you used a different cable to connect the monitor to the computer. (I'm assuming you used an old 15 pin monitor cable or whatever those old cables were?)

Without getting into your BIOS:

So on your computer, you probably have an onboard video card (a video card built into the motherboard itself), and a dedicated video card (probably where you're seeing the DVI out).

It may be possible that you have the on board video card (with the traditional connection) disabled, when the dedicated video card is plugged in.

This isn't rocket science, so don't worry. Phillips head screwdriver is all you need.

Pull the side panel off your computer (assuming it's a tower... if not, it's the top panel). Once you have it off, you'll see that video card plugged into a slot on the motherboard, with 1 phillips head screw holding it in place (inside, near the back, where the DVI port is).

Pull the screw, and the video card should come out. From there, the BIOS should recognize your card is missing, and thus revert to using the onboard video card.
