Weird Monitor Problem

by DB210 / November 25, 2008 2:22 PM PST

Ok, I bought a 15-Pin standard VGA cable to plug my laptop into my TV. Everything worked fine, but later problems started.

When I went to boot up my computer it just automatically started up with the TV as the default monitor. This would be fine, except for when this happens, my Laptop no longer detects the built in Laptop monitor.

This stayed like this for a month, then it randomly booted up with my laptop monitor as the default, and ran perfectly.

Now, all of a sudden, it no longer detects my laptop monitor again, and i can only use my laptop when hooked up to an external monitor.

*** is going on?

How Are Your Graphics Card Settings For The Monitors
by Grif Thomas Forum moderator / November 25, 2008 11:31 PM PST
In reply to: Weird Monitor Problem

Have you got them set to "Clone" the image so both displays are the same? Which monitor is set as the "Primary" display? (Make sure it's the laptop.)

Hope this helps and let us know more.

Well the problem is my laptop monitor isn't being detecting by my laptop at all. I cant choose to change the displays or settings because as far as my computer is concerned, my built in monitor doesn't exist. The laptop monitor doesn't turn on or show any sign of activity.

There is still 2 monitors being detected under the personalize option (Right Click - Personalize - Display Settings), but they are both the external monitor. When I choose to switch over to the second option, the screen just flashes and the external monitor again is the only thing that displays any image.

Please Try Installing An Updated Graphics Driver
by Grif Thomas Forum moderator / November 26, 2008 7:34 AM PST
In reply to: Well..

Since you mentioned the "Personalize" option, it sounds like you've got Vista running there.. (Unfortunately, you've still not given us any information about the computer such as make and model and operating system..

That said, there are frequent updates for Vista's drivers.. Visit the video card manufacturer's website and download, then install the most recent driver update for your card.. It might fix all of your issues.

Hope this helps.

Then My Next Step Would Be,,
by Grif Thomas Forum moderator / November 30, 2008 9:55 AM PST
In reply to: bump

...Take the laptop to the repair shop.. Sorry I haven't responded sooner.. Visiting family during Thanksgiving holidays.

Basically, if nothing is making the laptop display come back, then you've got a problem with the display.. We just fixed one like that here.. An external monitor allowed us to use programs but the main laptop display died.. Replacement or repair of the screen, or it's connecting cables was the only fix.

Hope this helps.

Then It Can Also Revert to 'Bad' Again Also...

Now is a good time to start looking for a replacement. Your current monitor may last an hour, a day or two, or maybe longer, but it will probably do the same thing again.

Hope this helps.
