Question about Microsoft ChiMei CMV938D 19" Widescreen LCD Monitor

1 Answer

I have a Chimei 22" LCD monitor that shuts down as soon as I plug it into a computer. IOW, without the video cable, either VGA or DVI attached to a computer, the monitor turns on and "No Signal Input" message appears on the screen. But as soon as I attach a cable to a computer, the power light goes off and I get no picture. Is this more likely to be the PS board or the video processing board?

SOURCE: Exactly the same problem on boot-up with Likom (Futura) HD19A mon

ok, if your computer is able to boot until you able to use it yet the screen is showing none yet working too, i suggest you change your data cable from the computer to the monitor. i once had a problem like that. it must have been damaged by high input of charge and burnt off though it did not show.

thanks,

wonder

SOURCE: I have exactly same problem

Sound like your display is having issues with the inverter board. When the power supply detects a short circuit, it turn off by itself. When you try several times, you may be able to "bypass" the circuit protection but the damaged parts still having problems. This issue may be related with the DELL display issues.

The display needs to be fixed by someone with experience in electronics repair.

What is the best way to connect 2 computers to this monitor


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)

2nd monitor does not work with DVI to VGA converter cable. My video card has VGA and DVi ouputs.


The problem could be in the adapter to the video card. There are different types of DVI connections. If the adapter does not have the proper set of pins then the card will not recognize that a monitor is connected at that port. Monitors themselves have no bearing on whether a single or dual monitor set up will work or not. Digital Visual Interface Follow this link, it may help you determine if the adapter you are using is correct for the graphics card.

If its a flat screen monitor ?

eMachines flat-screen monitors offer high quality at low cost. eMachines flat-screen monitors are compatible with most brands of PCs. Issues with eMachines flat-screen monitors can arise from faulty power sources, cable problems and incompatible settings. These issues can be resolved by testing step-by-step each possible cause.

Plug the computer's power cable firmly into a working AC outlet. Press the computer's power button.

Check the LEDs on the front of the computer case to confirm that the computer receives power. Plug the eMachines monitor's power cable into a working AC outlet. Press the monitor's power button. Check the LEDs on the front bezel or power button of the eMachines monitor to confirm that the monitor receives power. Orange or blinking LEDs indicate low power or no signal. Green LEDs denote a working connection.. Perform a monitor self-test. Switch off the monitor. Unplug the video cable from the monitor. Press the eMachines monitor's power button. An eMachines logo, Windows logo or "no signal" message indicates that the monitor is working properly. Plug the eMachines monitor's video cable into the video port on the computer. Attach the monitor's included DVI-to-VGA adapter to the monitor's VGA cable if your computer has a DVI port (15 or 25 pin-slots with 1 side slot) in place of a VGA port (15 pin-slots, no side slot). Press the eMachines monitor's input button to change the monitor's setting to match the computer port used. Set your monitor to DVI if connected to your computer's DVI port. Set your monitor to VGA if connected to your computer's VGA port. Connect the eMachines monitor to a known working computer with a known working video cable if the problem persists. Contact Gateway, eMachines manufacturer, if the monitor issue is not resolved. Hope this helps.

I have an Acer Monitor X223w - is it capable of hooking up as a douple monitor to one computer?


Any monitor can be used as the second monitor for a computer. However, your computer's graphics card must have two outputs. Some simpler graphics cards, most on-board video chipsets and all laptops *do not have* two outputs. Please check the back of your computer for two VGA outputs, or one VGA and one DVI output (you can use it by connecting a DVI cable to your monitor, or by plugging in a DVI to VGA adapter).
If your graphics card does not have two outputs, or if your computer uses an on-board video chipset, you can buy another graphics card to replace the one you're using.

Im not sure if i am supose to plug the dvi-d in cord in and the vga-in cord to


Your video card needs to have DVI output port for you to use the DVI cable, otherwise you can just use the VGA cable.
DVI is supposedly t give better pictures due to all digital signals compared to VGA which is analog.

If 'yes' to both, then you need a DVI-to-DVI cable.

Faulty VGA input


It is uncommon to have a faulty VGA input, although occasionally the pins get bent or broken on the cable. First check the cable.

Have you tried using a different source?

Some graphics cards/computers will only output DVI and VGA separatly and not at the same time. You may have to go into the display settings of your computer and change the output from DVI to VGA.

More details would be great,

Thanks!

Dell C521 Where to connect monitor?


This means that you have an external video card (which is not outside the computer). This video card will be plugged into the motherboard. That message is saying that the port on the back of the computer that your monitor is plugged into is the wrong one. You need to look for another port on the back of the computer.

Here is a picture of a VGA port that you should use if you have a VGA cable to connect the monitor (Blue Ends).

Here is a picture of a DVI port that you should use if you have a DVI cable to connect the monitor (White Ends).
http://zedomax.com/blog/wp-content/uploads/2008/09/dvi.jpg

So depending on the cable and connections that are available on your computer and your monitor depends on what you have to use. I hope that wasn't too confusing. Let me know if you need more info.
