    Comments about TV One 1T-SX- 644 Switcher (4 x 1):

    I needed a 3D HDMI switch to go with my 3D HDMI monitor. My monitor doesn't have external sound connections, so I also needed a switcher that included audio out so I could connect high quality speakers. Although there were many 3D HDMI switchers, I found only three (as of Dec 2011) that were HDMI 1.4 compliant. The rest were HDMI 1.3 which means they can't support full 1080p resolution in 3D.

    Of the three HDMI 1.4 switchers, I eliminated one because it didn't have audio out. I tried a second, but it took 30 seconds to switch between channels, and often didn't switch at all (just showed a blank screen). Then I learned that HDMI switchers take much longer to switch on HDMI monitors than they do on HDMI TVs (this first switcher took only two seconds to switch when I tested it on my TV). Next, I tried a full blown receiver, but it took up too much space on my desk, and it also took 30 seconds to switch between channels when using my monitor.

    Finally, I decided to try the TV One 1T-SX-644. I was skeptical, as it was over $100 less than the other switchers I tried, so I was concerned about the quality. However, upon receiving it, I found that it comes in a well-constructed, solid box; no quality issues at all. The size is also nice – much more compact than other switchers (only 7.9 inches wide as opposed to 10 inches). It is heavy, so it stays put after connecting the HDMI cables (you can also get an optional rack mount kit).

    Best of all, this switched between channels in only 5 seconds rather than 30 seconds as the other switchers did. I suspect that if you use this with an HDMI TV rather than an HDMI monitor, the switching time will be much less.

    The only minor issue I have with this is that the audio out is coaxial with no Toslink connection (which seems to be more common than coax), but a converter is inexpensive.

    I'm extremely happy with this. It's far better than the other options I tried and far less expensive too.
