Can this feature, two independent desktops be implemented in win2k or winXP? Also, regarding the potential invisible area on the screen, can't you just go to a small resolution on the larger screen so that the two screen match? I have to commend this list as I would never have thought about a dual-monitor setup if one poster (who I have forgot-sorry) had not mentioned it. I was on a website recently and they had a rack to set up multiple LCD screens on one monitor rack. I wonder what the video card would look like if trying to drive 3 or more monitors. What's out there just for grins? How expensive? I could have my labview diagram on one screen, panel on the other, dvd video playing on a third, etc. I just need to install more eyes into my head to view all of this. 8-)

Well, here at getemed most of the devellopers have now a dual monitor system. Most of us have matrox G550s, but almost all dual monitor cards should work well too. I had a project where the customer even wanted three large monitors. So I added two graphics cards, an ATI and a Matrox dualhead into the machine. All worked well, allthough (because of the 3 monitors) I had to use Win98 at that time. Here we come to a big caution: Win NT & 2k (no knowledge on XP yet) handle multiple monitors as two windows to a large and unique desktop, whereas Win9x used to have multiple independend desktops that just had to share one side with each other. This might be important, because almost all dualhead cards I know of have an excellent head as primary head, supporting video bandwidth of up to >250 MHz (and resolutions of up to 1600*1200). The secondary head is propably less capabal, supportimg only smaller resolutions. This may result in some area on the desktop that is not displayed on any of the screens in W2k. Example: One screen with 1600*1200 left and another with 1280*1024 right aligned at bottom. The desktop will be (1600+1280)*1200 and there will be an area of (1600, 1199) to (2879, 1024) that will be invisibel. On Win9x however there will be just two independend desktops. > Also, how about those kvm monitor switches? Anyone used those > in conjunction with the dual monitor graphic cards?

Monitor switches have to support the high video bandwidth in order not to damage signal quality. Try it out for the equipment and resolution you are trying to use. > One other off topic question.

I can solder as I'm a EE by nature. AFAIK this is an internal damage that can't be repaired and never ever with a 'burning iron'. Nothing to say about your 'natural' solder art crafting. (Hope this is got as that joke it is intended to be. Joking in a foreigh language is not so easy.) The LCD producers have even defined a level of defective pixels that are considered as OK according to the production standards. Otherwise they would get too few panels being OK out of their production lines and those would be too expensive for mass market.
