1. change the VGA cable and test.
2. Plug to another PC or notebook and test.
if still no signal, it might be the display board inside the LCD is faulty.
You need to get a certified technician to fix it.
If cost is higher than 1/3 of a new 18.5" new :LCD monitor; I think you need to think of purchasing
a new LCD already. As new LCD will cover you with 3 years warranty.
this should be easy...go to your desktop...right click on it and choose "personalize" it will open up a window. on the bottom it will say display settings...click on it...at the top right it should say "identify monitors" click on that...if that dosent work.click on the monitor that has a 2 on it and it will ask you if you want to add a monitor...it should work
if not, post a comment and i will check back with you
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.
The acer LCD monitor is plug and play.You don't need a driver.But unless you have a graphics card that supports at least 1440x900 you have problems. Also if your card has a div connection, use that instead of the analog connector, The monitor comes with that connector. Use the old one to connect a second CRT monitor if you want. Don't connect both to the lcd monitor and to the computer unless you are using a second monitor. Like everything these days, every purchase seems to need an upgrade of sorts, On board graphics **** anyway. Buy at least a 128 MB graphic card with a digital connector and more RAM never goes astray.....
your describe: connect a laptop VGA out to a monitor but no signal: you need check
1) newer monitor have two signal interface (analog or digital) and you may try to do a logical change the signal way by select buton
2) any laptop have two way display (local LCD or extenal VGA) change by the key (fn+f key showing creen icon)
Cant say for sure. The display seems to be working, and the computer signal seems to be the problem. It could be a faulty cable. Check the pins on the cable monitor and see if they are bent, etc. If the connectors are Ok, it could be the converter or the main board that has the fault. This could be caused by a power surge, or just a mechanical failure. There is no easy diagnosis for this\ one, without actually checking the parts. I would recommend taking it to a repair place.
