video controllers

By cstarbea830 ·
I have a LG L1981Q flatron monitor and when I try to install to Toshiba Satellite A105-S4034, I get a video controller hardware installation message. I cannot find the driver for this video controller and I cannot install the monitor. Does anyone have an answer? I am using windows xp pro.

Digital or analog monitor?

by nepenthe0 In reply to video controllers

If analog, the VGA cabling should allow automatic detection as a plug & play device.

If digital, there may be 2 DVI connections to the computer (DVI-D and DVI-I). If your monitor is not HDCP-compliant (High Definition Copy Protocol), you must connect the DVI cable to the DVI-I port.

If a digital monitor is not HDCP-compliant, and you connect the DVI cable to the DVI-D slot, the symptoms are just what you describe.

LG L1981Q Monitor

by cstarbea830 In reply to Digital or analog monitor ...

The monitor shows Analog at startup. I have a svga monitor cable for connection that I am using. I do not have an adapter for the DVI-D cable. The seller on Ebay is supposed to send it to me. This monitor is supposed to have analog and digital capabilities. I just wnated to use this as a multiple monitor for my laptop.

Dual monitor for laptop?

by nepenthe0 In reply to Digital or analog monitor ...

1) Did you try the F7 toggle? Check your laptop user manual for the function switch that toggles the display between the native monitor and an external monitor. There should be a microscopic icon embedded in the function key that identifies this toggle key.

2) Check the monitor settings:

Control Panel > Display > Settings

Click Advanced and look for parameters applicable to your system. Also check out the Troubleshooting button.

If your monitor accepts a VGA cable, your computer should detect it and supply the appropriate driver from the Windows data base.

3) The monitor should be connected and powered up when you power-on the computer, so the BIOS can detect this output device and enable the driver.

When you plug in an external Monitor on a NB

by OH Smeg In reply to video controllers

You have to switch the Video to the external Monitor with a Keyboard combination depending on the NB in question this Key Combination varies but it is included in the Owners Manual for your NB.

Look at the Function Keys along the top of the Keyboard and see if there is one with what looks like 2 monitors on it then press the Shift & that Key down together. If there are no markings on the Keys you will have to read the manual for a way to do this.

According the Toshiba's User Manual the Key Combination for this NB is the Function Key FN and F5 which need to be pressed together.
