Hi
I would like to ask about your display setups on work desks because recent changes in pandaboard kernel moves me into 'lets buy another lcd' direction...
Now I have two displays on my desk:
- 24" 1920x1080 - DVI port is main display of my desktop - VGA port was used with some boards in past - HDMI port was never used - 20" 1680x1050 - DVI (with HDMI->DVI adapter) is main display of pandaboard - VGA is secondary display of desktop or primary display of other (rarely used) PC
But Pandaboard has two video outputs: DVI and HDMI. For most of time I used HDMI output but it was with Ubuntu 11.04 kernel. Now I am testing Linaro WIP kernel and it has working DVI output rather then HDMI one...
Switching ports on panda requires powering it off in order to not damage it. Guessing which port works is not a way. Connecting panda HDMI to 24" HDMI is also no solution cause this will leave me without display for my desktop.
How you people solve that in other way then buying yet-another-lcd?

I've got ATEN CS1794 HDMI+USB KVM available here [1]. It comes with 4 fat cables for connecting HDMI, USB, Sound IN/OUT, is quite compact and optionally rack-mountable. I use it to drive my monitor+USB hub and switch between my laptop, beagle, helper desktop and PS3.

I have always been put off by the ridiculous prices of HDMI/DVI KVM switches. What kind of circuitry could they possibly contain that costs that much?
I believe they are just pushing the prices as high as the can get away with. They just need to keep the cost at less than buying 2/3/4 monitors (which is a very high upper bound), in order to make the deal look sweet. I would very much like to be proven wrong, but at least in my eyes it looks like a scam.
Unless space is a severely limiting factor, I would rather spend that money on buying separate screens/mice/keyboards.
Thanks, Alexandros

Looks like switching isn't too expensive to me: http://www.amazon.co.uk/Duronic-Switch-input-output-Switcher/dp/B0020426AG/r... http://www.lindy.co.uk/usb-switch-4-port-usb-2-autoswitch/42784.html
Yes, it is two buttons to press instead of one, but having a real USB switcher instead of a KVM solution where you can only switch a mouse and keyboard (the set up I have) sounds great to me.

I use something like that as well:

I really don't get Alexandros' rant about it being expensive!

I was specifically referring to HDMI/DVI (not VGA) KVM switches, for which the average price seems to be > $100 for 2 ports and > $200 for 4 ports.
As James pointed out, though, there are some plain HDMI switchers with more reasonable prices. However, that only reinforces my claim: HDMI/DVI KVMs are ridiculously overpriced.
Thanks, Alexandros

The KVM I mentioned has full selective switching support, I can plug a thumb drive to device A, sound to device B, display to device C and input to device D.

Well, for display I think a soln like KVM swith would do in this case. For mice/screen, for ex, I install quicksynergy (or cli version synergy) in Panda and Host and configure to run as startup application. As a result I am able to use touchpad and keypad of my laptop to manage Panda.
Off topic, I have been thinking of virtual FB over USB so that headless devices like Panda and Beagle wouldn't need a dedicated monitor while working on non-DSS stuff. I haven't yet been able to take time out to do it.
Njoi!
