Could be a virus. Keyboards have been known to be hackable. They contain microcontrollers with flash memory. Only a matter of time before somebody installs their own code.

But which graphics card has that and can do that? Sounds to me like reliving the dual-link DVI experience: First having to find a card that supports dual-link DVI, and then one that also supports the whole resolution; I have a Radeon X850XT at home that has two dual-link DVI connectors, but supports only up to 2048x1536. Also, of the two graphics cards I bought after my 30" monitor (which has DisplayPort among other connectors), none has DisplayPort. >The 30" screens are particularly challenging to drive, because they >usually have no scaler inside, so you have to get everything right to >drive them. Do you mean "scaler" as in blowing the picture up to full screen? My Dell 3008WFP can scale, and some of the things it does are quite impressive: I have a picture of picture-by-picture mode (two computers displaying on the same monitor, each getting a 1280x1600 half-screen), with one half being driven in 1920x1440 scaled down to 1280x960. The result was still surprisingly readable. I also have the impression that some graphics cards (in particular, an Nvidia 8600 based card I tried) scale the picture in the graphics card: Even when I asked the monitor for 1:1 display (which worked as intended with other graphics cards), I got a scaled-up image from lower-resolution modes. - anton -- M.

A reboot should take no longer than when the mouse is first plugged in. I have never come across a wired mouse with any perceptible delay from being plugged in to being usable. -- Mvh./Regards, Niels J�rgen Kruse, Vanl�se, Denmark

From the spec, it looks like even the newest ATI 5x cards (which fully embrace DisplayPort) currently only has DisplayPort 1.1 on chip - 6 in total, each of them carries 4 TMDS transmitters, and they spec it up to 2560x1600, i.e. "only" DisplayPort 1.1, limited to 1.62GHz symbol rate. At least their "Eyefinity" technology would make it possible to just use several DisplayPorts together. > Sounds to me like > reliving the dual-link DVI experience: First having to find a card > that supports dual-link DVI, and then one that also supports the whole > resolution; I have a Radeon X850XT at home that has two dual-link DVI > connectors, but supports only up to 2048x1536.

BTW: Your Dell apparently is currently the only 30" monitor which *has* DisplayPort... all the others are DL-DVI only... -- Bernd Paysan "If you want it done right, you have to do it yourself" http://www.jwdt.com/~paysan/ |
