    The easiest way to extend your display is to hold the start button and press the "P" key. Use the arrow keys to navigate to the "Extend" box and hit "enter."

Right click the desktop and get to display properties. Might have to use the fN key and to enable the external monitor VGA port.

Blank screen


It Could be because your laptop is infected with Virus . Due to Virus your Explorer.exe File was corrupted. If now computer is all right after restoring then I'll suggest you to use Good Antivirus Program and regular update it and Scan your Window Regularly.

The screen on my compaq presario cq56 is black


The problem is caused by the inverter board, "just below the screen" is more than likely the problem, or it is the backlight behind the LCD display, "built in" less likely.

Compaq Presario CQ56-115DX shows a blank screen on boot, but runs perfect on external display


If your laptop appears to boot up and the hard disk LEDflashes, then the problem is probably a back light fault. This can be a faultyinverter or a faulty CCFL lamp.

Laptop screen blank all white


Either your LCD Video Cable is not plugged in snuggly or the monitor is slowly going bad. The fact that you can see the images on an external monitors says your Video Graphics Card is working fine. You'll need to disassemble the laptop to get to the cables. Get a quote from your local computer shops, then try the guys at: http://www.generalsystemsconsulting.com Most times they will fix it and ship it back by Fedex or UPS cheaper than any quote you obtained including the shipping.

I have the cq56-115dx laptop....it was dropped on the ground by accident....when turned on you can see a definate crack in the right hand corner and a couple vertical color lines across the top of the...


if the screen has crack on it the only way is for you to replace the LCD or you may contact your manufacturer to extend the warranty. I believe that it will cost you more if you bring your laptop to a regular technician than renewing your warranty.

Just got cq56-115dx laptop this morning. turned it off after setting it up. Turned it back on and only have blank screen. Power shows lit up.


Hi.

Remove the AC power (charger) and then take the battery out. Plug in just the AC power supply and turn the laptop on, see if it boots up and shows a display on-screen. If it boots let it boot up and then shut it down as normal. Reinsert the battery and try as normal.
If you still get a blank screen can you then tell me if you get any post (splash) information like the Compaq Presario logo before it goes blank.


Good luck.

Right clicking on desktop, no graphic option for external monitor is coming up on presario 700c win7


Just right clicking does not always call up the second monitor option.

You should select "screen resolution" after right clicking

Then ensure there are two moinitors available.
If not check all connections to the second monitor inc the cables.

Make sure that the multiple display option is set correctly too eg extend these displays,
OR duplicate and NOT show desktop on display 1 (or 2)

Also check you have the latest drivers installed for that model.
DO NOT RELY ON THE MICROSOFT DRIVER UPDATE !
Go to the Compaq site and get them from there !
