Monitor display problem

What operating system are you usign?
Presuming it's Windows, wWhen you say "boots fine" you mean you actually reach the desktop, the "welcome" screen or the Windows startup logo?
By your description somehow I guess you have a startup problem but need some feedback about your computers status

You say the power light is orange--I'm assuming that you mean the monitor.
This indicates the monitor is not receiving a signal from the computer.
Assuming that the computer actually powers up (fan runs, you can hear the hard drive being accessed, etc) then your problem lies in the video card.

If, on startup, you do see the BIOS info and maybe even the Windows splash screen before your monitor goes dark, then the problem lies in the video card drivers. In this case, starting in safe mode will work and allow you to download and install new drivers.

It can be that your PC video resolution is set higher than 1024 x 768 @60Hz for the monitor to display correctly.

Try this per HP:
HP Business Monitors - What Do I Need to Do When the Message Sync out of Range Displays on the Monitor? ISSUE: What do I need to do when the message Sync out of Range displays on the monitor? When the video card signal exceeds the frequency allowed for the monitor, the following error message may occur: Sync out of Range SOLUTION: To avoid the message, lower the resolution or vertical frequency of the video card. Reboot the system and use the VGA mode to force the video card driver to lower its resolution. Follow these steps.

1. Shut down and restart the system. For consumer systems such as HP Pavilion desktop PCs, push the Power button once. For commercial systems such as HP business desktop PCs, hold down the Power button for five seconds.
2. Immediately after seeing the HP/Compaq logo screen, press F8 at system startup to initiate the bootup menu.
3. Scroll down to highlight Enable VGA Mode , and press ENTER .
4. After Microsoft Windows completes its bootup process, access the Display Properties and select a desired resolution, which is compatible to the connected monitor.

There may have been a software driver for your monitor for windows Vista to set the correct parameters
- here’s what I found on Microsoft’s site but only for Windows 7

Here’s some info about drivers for monitors on windows vista and 7 :

That's not monitor problem, it's your CPU, probably the Operating System crash!!!( Windows,etc).
Try reinstall it to solve the problem...

you mentioned monitor. this is a laptop right? so monitor is the lcd correct? now when you turned on the laptop and sees dell logo it means display is ok. after windows logo or after you type in your password display goes black? try startup repair first. using the windows media.

first problem could be the hdmi cable you are using is loose or broken.second, the display mode you selected was wrong, try to go to desktop and right click and choose nvdia control panel and choose the nview display mode to use,select the only use one display(single)and apply.

Not all monitors can display the same resolutions. You may have has the Dell monitor set at something the Acer can not handle. Try rebooting and if you can see the Dell startup screen press F8 as soon as it disappears. This will give you the Windows Startup Options menu, which is text and should display on any monitor. Then select VGA MODE, which is the lowest common denominator for graphics. You should be able to see the Windows display at a much lower resolution (ie, larger fonts and icons) than usual until you can reset your graphics properties to work with the new monitor.

Your display resolution is set to something outside the range your AOC supports.

Start Windows in VGA mode (pick that option from the startup menu you get when you press F8 after the manufacturer's logo comes when you turn the computer on). Then set the display mode to 16-bit color and 800X600 resolution. This will allow Windows to start up next time with settings just about every monitor can handle.

Once WIndows is up and running, make sure you change your display settings to something the monitor can handle. Specs are in the manual or on the manufacturer's website, but resolution of 1024X768 should be another safe choice. You should also think about installing any driver software supplied with the monitor.

Hi Rachel,
The old monitor was set to a resoloution that is higher then you current monitor can handle. This is normally the case when changing from a CRT to an LCD

Try this:
Unplug the video cable from the back of your computer.
Start the computer and wait for about 2 minutes.
Press the power button on the front of the computer just once. This will **** it back down safely again.
Plug the video cable back in, then restart the computer with the monitor turned on.

If this dosn't work then try this:

1. Turn the computer on (have the monitor already powered up)
2. When the computers bios/splash page goes away begin to press F8
3. You should get a Windows Startup options page.
4. If you see the WIndows Logo you normally see when it loads, just hit the reset button and try again.
5. In the Windows Startup page, select Safe Mode and press enter twice
6. Windows will now load.
7. On the desktop right click anywhere there is nothing.
8. Select Display Properties, a new window will open
9. Select the last tab at the top of the window (properties)
10. You will see a slider on the left side, move it to 800x600, select apply, then close the box.
11. Restart Windows.

If that fails, then please post back and we can try something else.
