[CQ-Contest] Size of Dual Monitors

There has been some discussion on the video interfaces. I've done some
research on these. My info may not be 100%, but it will make one aware of
the differences. There are four of concern. VGA, DVI, HDMI and Display
Port. There is Thunderbolt also, but that is an Apple interface. VGA is on
its way out. If purchasing new, I'd make sure my monitor has one of the
digital interfaces if it has VGA. The other interfaces are all digital. DVI
came first and is a video only interface. It can send VGA out the same
connector, if necessary, but that is not done often. HDMI is big for TVs,
and has the same signal lines ad DVI, but it can pass audio if the monitor
and computer support it. A simple interseries adapter can change between
DVI, HDMI and Mini-HDMI. 1920 x 1080 is highest HDMI resolution. Maximum
frames per second is 30, but that will rise to 60 when HDMI2 becomes
popular. 30 fps is just fine for what we normally do as well as HDTV. Now,
if you build a computer with an HDMI port, you have to pay someone money to
do that. Hence, the computer industry developed Display Port. The signal
lines are different and, since most monitors do not yet have Display Port,
a complex conversion adapter seems to be called for, HOWEVER, if you get an
interseries adapter, the computers today recognize that an HDMI monitor is
connected to the Display Port via an adapter, and send out HDMI signals
instead of Display Port. Dispaly Port does do audio also, and can do 60
frames per second. While the preceding may be somewhat confusing, just be
wary of the interfaces.

I discovered interfaces could be a problem. In my case, I hooked my laptop
to a monitor via HDMI. Worked great. Then I got a docking station. Went to
plug my HDMI cable into the back, and it wouldn't fit.The Dock had Display
Port. Looks like HDMI, but has a slightly different shape.  After a "What
the...." moment, I started my research.

As to position of the monitor, I agree with others. Main one front and
center, having to look down a bit. Radio off to the side so one does not
have to reach over the keyboard to operate the radio. Putting the keyboard
below the desk is a good idea also, with maybe a remote tuning knob near
the keyboard. Hope you find a decent arrangement the first time. --Mike,
