Question about Compaq TFT450 14" LCD Monitor
I own a compaq TFT450 monitor and want to know if I can just use a USB cable to get it to display as a second monitor. I already have a LCD monitor on my Nvidia Card, but I notice that on the compaq TFT450, that there is a USB cable hook up on th ebase stand with a picture of a monitor on it, and I have been trying to get my computer to recognize it as a second monitor when I plug it in to my computer. I get nothing on the monitor except a "check video cable"notice on the screen.
No USB is not a video cable ever.
i guess you lost the manual, that it?
it tells you what the USB does.
page 2 tells you that is a USB hub, you use it to connect other USB devices, for say pc that has only 1 or 2 USB ports this allows more.
it is not related to VIDEO in any way.

Here is a pin connection specification for the ac power supply (dual voltage adaptor)
>socket/plug for a Compaq TFT450 LCD Monitor that she
>supplied (edited for further clarity).
>The pins of the male connector (a PS2 mouse type connector) should be connected like this:
> 1 2
> 3 I 4
> 5 ^ 6
> GND GND
> 5V I 12V
> 5V ^ 12V
>For clarification - the male will be the end of your cable, and not the socket on the monitor.
>The I is the central polarising bar of the connector, and the ^ is the notch.

SOURCE: Monitor "Goes to sleep"
Have you tried to go in thru the control panel and select "display"? From here you can go to the screen saver section and adjust the time it takes for the screen to cut out. Of course you want to use a monitor that you can read before you set up both of your screens.. See if that helps....

The maximum resolution for the MV540 is 1024X768 @60Hz refresh. The other monitor isn't giving you an error message because not all monitors have that feature, but both the monitors are unable to display whatever data the computer is sending. If the display is normal until you start the game, then the game itself is setting the resolution to something out of the monitors' range. You'd need to set the game up to play at a setting the monitors could handle. I've never played WoW so I have no idea if the game offers a way of selecting the resolution. The game may simply require more graphics capability than your monitor can provide. Most systems now are using 17 or 19-inch flat screens or CRT's, and they offer more resolution and refresh rate options.

Check that the signal cable from the computer is firmly connected and that there are no bent pins in either end. If the trouble continues, the problem is in the monitor itself. Given the low replacement cost, it's uneconomical to try repairing these.

If the monitor continues to have a blank screen when connected to another PC, then the hardware (internal electronic part/s) is having trouble powering up the panel/ccds and it should be replaced/serviced according to the terms of the warranty. I suggest to bring the unit to a service center to properly diagnose & fix the problem. best regards
