Thanks for the replies.
I went with the advice that an active/powered switch should do the job as the likely cause was simply the passive nature of the current switches.
So I headed over to B&H this morning, picked up 2 different switches to test, as I can keep and use both if they both worked... and they both worked perfectly.
Originally I was tempted to splurge on a couple of the $200+ models just to 'git-er-done' (and it's not my money
), but I put faith in the advice in this and other threads and bought a couple at $40 and $50 which both work well. One auto switches, which is very useful, and the cheaper one requires a quick press of the selector.
Again, won't spam any links here, but if you're in the same situation as me and want a solid HDMI switch at a good price, these are the two I picked up that work for me.
Eversun Technologies HDMI-4I 4 x 1 HDMI Switcher - $39.00
Kanex HDMI 5x1 HDTV Digital Switcher - $49.50
They both work well, both have remotes, both have buttons to switch inputs, but there are couple of things to keep in mind between them...
- The cheaper Eversun model does not autoswitch to an input upon receiving a signal from that input.
- The Kanex has a blinding bright blue 'power/on' LED on the front. Not a problem for me as the unit is going under a table, but I would not have this next to a TV without some black electrical tape over that LED. It was painfully bright when I accidentally powered the unit up a foot from my face w/ the LED facing me.
