I've been searching hi and low for a laptop that will support dual external monitors. I know that extending the desktop to a single external monitor is quite common but I need to find a system that will support dual external monitors. Does anyone have any suggestions?
Do u want to run 2 external monitors or "dual screens" which XP provides by adding a second monitor to your primary on notebooks? Check on your graphic card type. My notebook Sony VGN-A790 17" 1920x1200 w ATI 600x 256 MB card went blank after connecting a Samsung 245bw as a dual second monitor after using a 21" ViewSonic 1600x1200 for a year+. ATI website states the problem exists when using digital cables. No fixes or solutions exist! I used an analog cable.
Of course it's not going to work if you're trying to run a 1920x1200 monitor on a single link DVI connector. It's not 'digital cables' that are the problem, you're running outside the bandwidth of the single 165mhz TMDS, and that's a problem you'd experience on any old graphics solution, however on newer chips they integrate dual-link DVI support. Running out the analogue portion of a DVI-I will let you run off of the integrated 400Mhz RAMDAC thus giving you monitor support up to 2560x1600 @ 60hz.
And being XP doesn't matter either as it supports up to 8 displays pretty easily, as long as there is the hardware to do it, but trying to run outside of the resolution supported by the TMDS or RAMDACs just won't happen regardless of what you use.
I recommend anyone serious about multi-monitor support should use a 3rd party app like UltraMon to manage profiles and desktops since they do a better job than Hydravision and nView.
You're going to want to DVI-D if you want to output to the 30" style of monitors anytime. Usually the GPU's control panel program, like CATALYST for ATI or nVidia's Control Panel will have the option to configure for external monitors. Many notebooks have S-Video (an option), VGA, DVI, DVI-D and even HDMI outputs.
Yeah the dual and triple head to go are good, I wasn't thinking of external solutions, but that's an option, although a tougher one with the resolution restrictions.
If he's not gaming there's of course PCMCIA and even USB based additional monitor add-ons.
I almost bought an open box USB one at FutureShop on the weekend fo $29, but I'm not really THAT curious, and for the money an HD-DVD copy of American Werewolf in London earned the attention of my wallet.
Like the Dual/Triplehead to go though, nice unit, just finicky though.
Pauldh was playing with one and considering setting up a triple projector setup for huge surround gaming.
I have a laptop with a geforce go 7300 graphic card that has both VGA and DVI-D output ports. I have an external monitor connected trough the Vga port and it works perfectly, and I was wondering if I could connect a second external monitor via the DVI-D port and have two external monitors working at the same time. Is that possible with this nvidia card?
Yes, one uses the on chip RAMDACs (VGA) the other uses the TMDS (one or two) so those two output won't be an issue, but if it only has 1 TMDS then you will only be able to use the VGA when the main laptop LCD isn't bing used since the LVDS connection runs off of the digital path and usually converts the TMDS output.
