Question about Computer Monitors

Monitor works at Startup, then goes black

I have a new Acer AL2002W LCD monitor that I hooked up to my laptop. I turn on the monitor, then computer as instructed. The monitor shows the same display as my laptop during startup, then goes black. I get the message "No VGA Signal". I am also unable to get the OSD menu to display when I press the menu button on the Acer monitor. I have tried this with 2 different laptops, same problem. Any idea of how I can fix this? Thanks.

Yes you can fix this problem go in to start menu then control panel then double click display, then screen resulution and add the secondary screen, bc windows doesn't add the screen automaticlly you have to do it this way

I have my acer p205h 20 inch monitor hooked up to my tobshiba laptop and it works great except it will not go into sleep mode when laptop goes into sleep mode the monitor goes to there is not signal check...

Unfortunately, this is a standard problem, as when your laptop goes into sleep mode, it shuts off power to the secondary monitor, without giving it the signal to go into sleep mode. You could try digging around your settings, but most likely you'll just need to turn off the monitor when you're not using it.

My monitor comes on for about three seconds when I turn the computer or the monitor off/on and then it fades to black. It looks like the computer is booting up fine when I can briefly see the screen but...

Connect the monitor to the "video-output" port on your laptop, to see if the monitor is working correctly.
You make have to tell the laptop to send the video-output to "both" the internal LCD screen and the external monitor.

If it works, then your monitor is OK.
Restart your computer, and keep tapping the F8 key, until you get a menu of startup items. Choose the 'VGA' startup option, to select the "minimal" device-drivers for your video-card. With the "minimal" drivers, your monitor should still be working.

My monitor screen goes black it lights up about half the scree when i first turn it on then blinks like a light bulb that is not screwed in all the way then goes completly black acer al2002w

vandetucker, You should use your warranty and use it NOW!! When "IT" goes to "BLACK" can you see the WIN-desktop when holding a bright flashlight at different angles 1 inch from screen??? How old is unit? How many "ON" hours does it have? Your monitor isn't any different than a Gateway or LG or Phillips, VIEWSONIC, SHARP, Samsung, Sony, Dell!!! You will need to read a few of my other responses and follow some of the links to web pages that you find already in my profile on fixya, so that you will know what questions to ask about repairing your unit. Let me know WHAT YOU WANT TO DO after you have done some research about your BLACK SCREEN lcd monitor. Here is an option I just know you will love. You can do the trade for new 2010 monitor unit and the technician in the back of the computer store just might put $6 $8 in parts into your old AL2002WSD and have a nice wide screen for the new year. Yeah, and your monitor "blinks like a light bulb" !!! Oh my!! How right you are!!! Do you know anything about "cold-cathode-fluorescent-lamps"? You should also see if Acer has a cash+old swapout program for a same model refurbished unit??? You should also give ACER a little bit of lip about the poor reliability of their short lifespan electronic ballasts and CCFL lamps. Like to know what your going to do! 12fixlouie Bye for now

Try the "Display Swap" button (usually a Fn key). Some of these have several choices each time they are pressed, e.g. Laptop Display, External Monitor, Both, and NONE!). Hope this helps. Ian.

Monitor goes black

Sorry to have to tell you this, but this is common in LCD monitors. The reason that it is going black when it boots is for one of two reasons. You either have a bad power supply that powers your LCD or your LCD's backlight is blown. These can be repaired or you can purchase a new one. But if it goes black 9 times out of 10 is because the backlight is bad. These can be repaired!
