Extend Desktop To Second Display Freeze with Acer 3000

Posted September 27, 2006 * Comments(2)

I’m having a strange problem with my Acer laptop that renders use of a 2nd monitor impossible.

What I’d like to do is to use a 2nd monitor with the “Extend my Windows desktop onto this monitor”. With the acer apparently you have to use the SIS utiliy instead of using the normal Control Panel windows display path.

When I enable the 2nd monitor and extend my desktop to it, the system freezes for 2-3 seconds every 10-15 seconds. The mouse stops, the display is frozen, nothing works for just a few seconds, and then everything comes back.

Here’s someone else having the same problem from the Hexus forum.

I’ve updated the graphics drivers and the Bios to the latest versions. I’ve also increased the memory size for the graphics card to 128M from the Bios settings. Still no luck.

Any ideas?

Here are the details for my setup:

Windows XP Home Edition Service Pack 2 (build 2600)

64 kilobyte primary memory cache
128 kilobyte secondary memory cache

    Hi, I have a lot of knowledge of computers and you might just have connect the monitor cable to your laptop and then just restart the computer. this worked just fine for me on about three computers.
    Sometimes for some computers, plugging in a second monitor is like installing new RAM without turing off your computer and it just needs to be off when you plug it in. Another idea is that you can activate the second monitor just by right clicking your computer background, go to graphic options, and click dual monitor or something. Extend desktop is also a fun thing to do.

    This Ky guy sounds ever so slightly big-headed.
    And it doesn’t sound like he has a clue on what he’s talking about.
