I can't believe it.
All this time, the monitors at work that we are replacing (old Compaq 18" LCD) had an S-video input. I could have been playing on the bigger screen all along! I've been playing all day, looks great. Now we are upgrading to the Dell 1907, which is a nicer unit... but I'd have to buy one of those converter boxes to use it. Even then, most of those need a power adapter to plug in, and every time I came to work I'd have to set the thing up. Using the old monitor, I just plug and go.
I should pay better attention....
