Computer powers up but no visual imge on monitor .Monitor shows

Acer produces a number of LCD computer monitors. Acer's monitors range from 17 inches to 27 inches. Some monitors offer wide-screen viewing, embedded speakers, high-definition visuals, and various display connection ports. Acer computer monitor problems include common issues such as dead pixels, error messages, and blank screens caused by incorrect connections. Some reviewers have also detected image problems with DVD playback on some models.

"Input Not Supported" Error Message Acer computer monitors such as the G24 may issue an "Input Not Supported" error message when users set the display resolution too high. The G24's maximum display resolution is 1920x1200 with a 60Hz refresh rate. Maximum resolutions vary according to the specific monitor model and according to the capabilities of the computer's video card. b> "Input Out of Range" b> Some Acer computer monitors may report an "Input Out of Range" error message due to incorrectly set monitor refresh rates. Much like the display resolution, each monitor also has specific monitor refresh rates with which it is compatible. Blank Screen or "No Signal" Error b> Like other monitors, Acer computer monitors feature color-coded power indicator lights. If the power indicator light shows green, the contrast or brightness levels may be set too low and should be adjusted via the OnScreen Display. If this does not rid the monitor of a black screen, the monitor may be experiencing hardware failure. The "No Signal" or "Check Cable message" may indicate a problem with the monitor's cable connection with the video card. This error may also appear on a blank screen backdrop if the monitor is plugged into the incorrect port on the computer or if the computer is frozen and needs to be rebooted. Faulty power cords or outlets may cause the screen to be black and to show no power indicator color. b> Image Issues b> Some review sites such as CNET have reported problems with streaking and ghosting during DVD playback on some Acer computer monitors such as the AL1931. (A "ghost" is an identical offset image as the primary or desired image.) Unstable or unclear image issues may be caused by incorrectly programmed VGA timings or incorrectly installed monitor drivers. b> Dead Pixels b> Dead pixels and sub-pixels can cause a variety of display enjoyment problems. Acer will only accept returns on LCD computer monitors that have "more than four (4) defective pixels per million pixels." Further, the central area of the monitor may have no more than one defective pixel. Acer does not differentiate in warranty terms between pixels and sub-pixels. Hope this helps.

If the monitor works on the other computer than the first computer is not outputting a signal and the monitor is going to sleep. Alternately the monitor could have a power issue and it will just shut off after a few seconds. I've seen that happen.

Hi, Hopefully you are seeing this error on the screen of your monitor. If that is the case,
do the following steps.
1 Shut down the computer. To do this, without looking at the monitor, hold the on/off button to your computer in for about 5 seconds. The computer should then shut down.
2 Shut off the monitor.
3 Unplug the video signal cable, the thick one that goes between between the computer and the monitor and then re-insert it observing not to bend any pins. There are two end screws that you will have to be loosened, although they may have not been tightened in the first place. When you reinsert the cable, hand tighten those screws.
4 If there is a similar connector on the back of the monitor, repeat step # 3.
5 Make sure that the signal cable is firmly attached to both the computer and the monitor. 5 Turn on the computer and see if it has solved the problem.
If it does not, examine the cable for signs of damage along it's length.
If it is damaged, replace it. you should be able to get a cable for stores like Best Buy, or possible from a friends old stack of cables.
Hope this helps,
Mark

Try unplugging monitor then plugging back in.

Before you begin
Check the following items before using the steps in this document:
•If you have a flat panel LCD monitor, unplug the monitor power cable, wait about 30 seconds, reconnect the cable and then turn on the monitor. This resets the electronics on the monitor.
•Make sure the monitor has power - the light on the monitor is on. If the light on the monitor is off, the monitor does not have power. Connect it to a different power outlet.
•If the monitor has a detachable video cable, obtain a second monitor cable for testing purposes in case the cable is bad.
•Disconnect all connected devices except the mouse, keyboard and monitor. This includes thumb drives and camera-type memory cards from card reader slots.
With the devices disconnected, restart the computer. If the computer starts and the monitor now displays a picture, a device is preventing the computer from starting. Update the BIOS to resolve this issue.
Step 1: Connect the computer to another monitor
Connect another monitor to the computer to determine which device has the problem (the monitor or the computer). This step is very important to help you determine if the problem is coming from the computer or the monitor. If necessary, temporarily connect the computer to a friends monitor for troubleshooting purposes.
After the monitor is connected, turn on the computer and the monitor. What happens?
•If the newly attached monitor does not display anything , disconnect the cable and continue at Step 2: Is the video connection damaged?
•If the newly attached monitor displays the first startup screen(s) but then goes black, there is a problem with Windows starting. Skip to step 5 .
•If the new monitor works , the original monitor or its cables are faulty. Do the following:
1.Replace the monitor power cable.
1.Turn on the monitor. If the monitor displays an image, you are done. If the monitor remains blank, continue using these steps.
1.Replace the video cable.
Turn on the monitor. If the monitor displays an image, you are done. If the monitor remains blank, continue using these steps.
1.If the monitor does not work after replacing the cables, replace or service the monitor.
Step 2: Is the video connection damaged?
Inspect the video cable and video connectors for damage. Check for sharp bends or breaks in the cable and bent or broken pins at the connectors. With the monitor and computer off, try to straighten bent pins with a small metal tube, like the tip of an empty mechanical pencil or the tip of a retracted pen.
Figure 1: Video connector
If you had to straighten any pins, reconnect the monitor making sure that the video cable is firmly connected and then turn on the computer and monitor. If the display is still blank, continue to the next step.
Step 3: Resetting and updating the BIOS
You can use these steps even though you will not be able to see anything on the monitor.
In case an item was changed in the BIOS, such as the primary display device setting, use the following steps to reset the BIOS back to its default configuration:
1.Turn on the computer and repeatedly press one of the following keyboard keys. Press the key about once every second for 5 seconds after turning the computer on.
◦For HP and Compaq computers that came with Windows 7 and Vista, press F10 .
◦For HP and Compaq computers that came with Windows XP, press F1 .
◦For Compaq Presario desktop computers built prior to 2002, press F10 .
1.Wait another 5 seconds.
1.Press the F5 key. This restores the default settings of the BIOS.
1.Press the Enter key. This accepts the changes.
1.Press the F10 key. This saves the changes.
1.Press the Enter key. This saves the changes and exits from the BIOS.
1.The monitor should display the first screens received from the computer (the logo screens). If not, find and download the latest BIOS update if one is available for your computer.
1.If a BIOS update was not available or the monitor is still blank, continue to the next step.

This could be a problem with the video output on your desktop, check with another monitor and see how long it takes for it to display when booting up.
Or this could be a problem with the monitor, these monitors after they age a few years some start to have the bulging capacitor problem. You can check for this by opening the monitor up and visually checking the capacitors for bulging.
To see what bulging capacitors look like check here.
Badcaps
That webpage also has tutorials on replacing bad capacitors.
If you have any more questions or if this does not solve your issue, let me know.

Have you verified the video card in the computer with a different monitor? Does the going to sleep message come up prior th the monitor going dark? The bulbs are ok since you do see a picture for a short time. The voltage swing you see on the power supply is too large. It should always be 12 v + or- 10%.

I have reviewed your problem and have the fallowing for you to aces.
First, power off all devices and monitor.
Second. disconnect all devices from the PC and Monitor.
Please make sure the monitor is disconnected from it power source.
Next, hook up monitor to PC and start PC, along with monitor.
Next, enter menu on HP vs17 and reset.
Allow to run for ten or 15 minutes, watching the video on screen for imperfections.
If all looks OK, hook up your other devices and enjoy.
I hope this has helped you. Please let me know how things work out for you.
Please rate.... Thank you.

Probably the video resolution or the monitor Refresh Rate (eg: 50/60/75 Hertz) is set too high in the operating system, which over-drives the monitor electronics and it is unable to display anything.

If you restart the computer manually (hold in the power button for 5 seconds, the computer will shut off, turn it back on again) you will see the normal BIOS and Windows startup display on the monitor, but then as Windows completes it's startup it returns to the error message you see.

To fix this, restart the computer manually and start the computer in Safe Mode. To do this press F8 just before the computer starts to load Windows, and choose Safe Mode. Once in Safe Mode, you should see the monitor working correctly.

Now restart the computer in Normal Mode and everything should be fine.

These messages are normal when the computer truly goes into suspend mode or loses the video signal (such as when the computer is suddenly turned off).
If the monitor displays any of these messages when the computer should be displaying video , do the following items until an image from the computer appears:

1.
Ensure the computer is really sending a video signal. To bring the computer out of suspend mode: move the mouse, press the spacebar, and press the suspend button on the keyboard twice (the suspend button has an icon that looks like a quarter moon).
2.
Ensure the video cable is connected (and connected to the correct video port).
3.
If you are trying to view video from a set-top box, DVD player or similar device, use its menu system to set the proper video output channel so that it matches the video connection are using. For example, if the monitor is connected to a satellite receiver via a second HDMI connection on the back of the receiver, select HDMI-2 (or similar) using the remote control for the receiver.
4.
Turn off the monitor using the monitor's power button and then restart the monitor.
5.
Cycle the power on the monitor as follows:
1.
Turn off the monitor. The power light on the monitor should be off. Leave the computer turned on.
2.
Unplug the power cord.
3.
Wait 5 seconds.
4.
Plug in the power cord.
5.
Press the power button on the monitor to turn on the monitor.
One of two things happens:
1.
The image from the computer displays on the monitor and you can use the computer again. This indicates that the monitor was unable to detect that the computer had awakened from suspend mode. Turn the monitor off when it is not being used or disable suspend mode. For some computers, updating the BIOS corrects these types of suspend problems.
2.
The power light on the monitor comes on but the screen displays one of the messages again. The monitor is not receiving a video signal from the computer that it can detect and use. Continue using these steps to adjust the Windows display resolution to the Monitor's native (default) resolution.
6.
Adjust the Windows display resolution to a setting that is compatible with the monitor:
NOTE: The native resolution setting for your model of monitor can be found in the Monitor User Guide, the monitor's product packaging, and product specifications.
1.
Restart the computer and press F8 repeatedly after the first logo screen.
2.
Select Safe Mode .
3.
Windows should open showing a Windows desktop with lower resolution and fewer colors.
4.
In Windows Vista, click Start , Control Panel , and click Adjust Screen Resolution in Appearance and Personalization.
In Windows XP, click Start , Settings , Control Panel and then double-click the Display icon and select the Settings tab.
5.
Move the slider bar until the native resolution for the monitor is set, click OK and restart the computer.
6.
If the native resolution is not available from the slider bar, click Advanced Settings , click List All Modes (from the Adapter tab), select the resolution, and click OK .
If the native resolution setting is not available as a selection in Windows, you can temporarily use 1024 x 768 to complete these steps. However, you should update the graphics driver on the computer. Updating the graphics driver can provide more display resolutions to Windows; possibly including the native display resolution for the monitor.

7.
Connect the monitor to another computer that you know is working to determine if the monitor should be serviced or replaced:
*
If the monitor displays an image from another computer, you know that the monitor works. Troubleshoot the video connection and graphics adapter on the computer.
*
If the monitor remain blank when connected to another computer, the monitor signal processing hardware may be bad. The monitor should be repaired or replaced.
