OK.

I had no idea about that. Thanks for sharing. How does this limitation
come about ?
It's the DVI clock speed, which is limited to a maximum pixel clock
frequency of 165 MHz. This works out at 2.75 megapixels at 60 Hz.
My current machine has a HDMI port and a VGA port...
You can get dual link HDMI. It all gets a bit complicated because
HDMI 1.3 allows 340 MHz, so in theory a single HDMI link should be
able to drive that Big Dell -- but I wouldn't bet the farm on it
unless I'd made very sure that both ends support such a high clock
speed. The Dell web page doesn't say.
