The challenge is finding and selecting an LCD monitor that matches the Tablet PC output at its native resolution. Any mismatch and the monitor will likely shrink or stretch the video, resulting in a blurry image. Further, according to the tech notes I've been reading many Tablet PC video cards will not put out the full range of display resolutions to the external port. That's why I'd like to hear from anyone who's currently using (or thinking about using) a Tablet PC with an external monitor at 1280x1024 or higher.
For the technically curious:
According to the specs, my Tecra M4 has an NVIDIA GEFORCE 6600 TE (128 Megabyte) video card. This is capable of driving an external monitor at resolutions up to 2084x1536 (Max). I'd love to have an external monitor that I can read at this size. Not sure I'll find one, however.
At a minimum, I'm looking for a WUXGA resolution monitor (1920x1200) which will allow me to view two full-size (A4 or letter) pages side by side.
Some display options:
24" LCD Monitors:
The new Dell 24" WUXGA (1920x1200) LCD Monitor seems to be the best value in this size. Dell has just dropped the price to $879, making it a great bargain.
30" LCD Monitors:
The Apple Cinema 30" HD display supports up to 2560x1600 resolution, which exceeds the video output capabilities of most video cards. At $2499, it's also quite a bit more expensive. It might be better to buy TWO Dell 24" monitors. :-)
Another nice monitor in the 30" category is the recently introduced Dell Computer UltraScan 3007WFP. This has a WQXGA resolution of 2560x1600, which is more than most laptops can support (There is some question as to whether the Tablet PC could interface with this monitor without a dual-link interface. I've not been able to find anyone who can answer this question with certainty.)
For anyone with a Dell or Apple 30" display connected to a PC:
I have a question for you: If I drive the 30" Display at less than it's native resolution, does the monitor setup have the ability to NOT scale the image? I know that this would result in a black border around the video but at least it would keep the image sharp and crisp while allowing me to take full advantage of the Tablet PC external monitor capability. I'd like to hear from you.
And, finally, if money is not an issue...
The IBM T221 22.2-inch monitor (2003 - Discontinued) features a resolution of 3820×2400, or just under 9.2 million pixels. If you have to ask how much, you can't afford it.
