All of the monitors we have have HD15 VGA inputs, most also have DVI and either DisplayPort or HDMI connections. Business class products don't eff around.
Only thing I wish they had was internal speakers (not for our office users, but for my Miggy, LOL).
I think the sound bars for most dell monitors are cheap on ebay and clip on the monitor(i was given a monitor with one is how i know). anyway,too bad on the gfx card, is that resistor there for the older vesa modes on the pII?
might remove it or snip one leg and see if that has any effect on the pass thru problem- it should'nt but...never know.
