This is the second go round - I realized that my previous description of the problem was inadequate.
I have an Acer TravelMate 2410 laptop with a cracked screen - the left third of the screen is useable, but the rest is not. I've been using a ViewSonic VE150 as an external monitor for the last year with no problems. Now, when I boot the system, I get the error message "Out of Range 23Hz/18KHz". This is after I get the Acer splash screen and the Windows XP boot up splash screen during startup. The VE150 drivers are correctly installed.
On the settings box, I can apply the check box to extend the desktop to the external monitor successfully, but when I check the "Use this device as the primary monitor" box, the Viewsonic goes black.
Video card in the laptop is Mobile Intel(R) 915GM/GMS,910GML Express Chipset, 128 Mb, Intel Video BIOS.
The Acer email tech said “For this error message try booting to Safe Mode and make sure the display resolution is set for 1280x1024 and set the refresh rate to 75Hz.” I tried this, but it didn’t work. While in Safe Mode, the external monitor came up as it should. Several others have made different suggestions about resolution and refresh rate, but nothing has worked. I've been into the device manager and the only strange issue is that there are duplicate entries for the video card, the laptop monitor, and the external monitor. I have yet to try and change any registry settings.
Any ideas???
