Question about Compaq TFT450 14" LCD Monitor

1 Answer

A compaq TFT450, can it be used with USB to View?

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.

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....

SOURCE: Monitor out of range when a game is booted up

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.

SOURCE: Monitor: Compaq TFT5015 Displays vertical lines

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.

SOURCE: i get a blank screen when i turn on the monitor

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

How do i connect compaq presario x1000 to external monitor


Hi Judy,

The Compaq Presario x1000 notebook offers connections for external displays at the rear below the screen hinge as show in the picture below:

steve_con_5.gif

Identifying the back from left to right: Ventilation slots, External VGA Port, S-Video Port, USB Port, USB Port, RJ-45 Network Jack, RJ-11 Telephone Jack, Parallel Printer Port, USB Port and 1394 (a.k.a. "Firewire") Port.

You can connect a VGA monitor to the VGA port (blue colored jack) very easily. Any analog VGA monitor should readily connect to it. Additionally, the x1000 can output its display to TV or other monitor that accepts "S-Video" signals. An "S-Video" cable will be needed to connect between the "S-Video" jacks on the notebook (next to the VGA Port) and one on the TV. It is important to note that not all TVs support both or either "S-Video" or VGA inputs. When ever the there is a choice of using S-Video or VGA on a TV or monitor, the VGA will provide the best looking picture, and should be used.

I hope this helps and good luck! Please rate my reply - thanks.

Hi, I have compaq 7540 monitor 17''. It is showing only part of the screen and when I shake the monitor or plug it displays full screen for a second and gets reverted. Please help on this issue.


Sounds like you have a bad connection somewhere inside the monitor or cable. Try using a different cable (if possible) or trying a friends monitor. If it works fine, then you know that's your problem. CRT monitors are very inexpensive nowadays, and you might be able to find one at a yard sale or thrift store for pretty cheap instead of trying to get it repaired. Hope this helps!

My Compaq 1825 monitor is showing pink/green instead of its usual colours. I went for dinner and came back to this.. wat do.


This is probably one of three problems that often screw up the colors on a monitor.

This is most likely a problem of your computer overheating. To fix this:

1. Open your computer and clear out any dust particles with a vacuum. Just make sure not to hit any of the parts of the computer and break it.
2. Get a cooling system. This could be as simple as pointing a fan at your computer and turning it on to buying a water cooling system. Just do something to try to keep your average heat lower.

This is most often the problem and will clear up your problem. If not it may be a problem of a bad cable.

1. To test this you could go out and buy a completely new cable and connect the monitor with that cable. If you don't want to pay for a new cable not knowing if that's the problem, just borrow a cable from a friend, neighbor, or your work and test with that. If it works with the new cable, buy a new one and that fixes the problem.

If neither of those solutions fix the problem it is most likely just a problem with the hardware in the monitor. If the monitor is still under warranty, contact Compaq support and have them replace it. If it is not, you'll need to buy a new monitor.

Thank you for using FixYa!

Flickering


Hello,

If the screen of your monitor is flickering, this is indicating that your picture board is about to go bad or already bad, but i would suggest you replace the cable that connect to the monitor before concluding on this, if after replacing the cable, problem still persist, you will need to replace the picture board on the monitor to solve the problem.

Take care.

Connection


Your HP notebook PC probably has a VGA (aka HD-15) connector. Check page 16 of this PDF to make sure - connector #2 is the VGA connector.

Your Compaq monitor also has a VGA HD-15 connector, so it should plug directly into your laptop's port after unplugging it from the other PC.

You will still need to plug the Compaq monitor's power cable into a wall outlet for power.

If you are going to share this monitor between your notebook and the other PC, you may want to consider purchasing a Keyboard-Video-Mouse switch (known as a "KVM switch") - there are many different models - you will need one with VGA, and whether you need USB or PS/2 keyboard/mouse connections depends on what your other PC's keyboard and mouse are.
