I was wondering if anybody can help me out with buying a HDMI Switcher? I need a 3x1 and im wondering why one is $300 and another is $30 on ebay? I tryed scanning threw specs and the only thing i can catch is the Video Amplifier Bandwidth? The $300 ones have a 1.65gbps range while the $30 only have a 140mhz range. Dose this make a big diffrence in picture quality and sound? Any help would be greatly appreciated! Thanks.

I'm sorry, I can't answer your question but I can provide some input. I bought a generic, inexpensive ($60) HDMI switch on Ebay that was "v 1.3 compatible." I went for that bit of marketing just guessing that it might matter. I don't know. It works just fine for my HD players which are connected through it to my receiver. The unit I have doesn't have remote controlled on and off but it does have remote control input selection. You can either leave it on all the time or, like me, turn it on when you put the disc in the tray. When I only had two players I had a $32.50 Monoprice 2 input switch that also had remote controlled on and off. It also worked fine with my HD players. I have no idea what you would gain by buying a $300 unit.

As for the spec differences: Normally, HDMI switches, cables, repeaters would be speced at maximum bit-rate (as in 1.65gbps (read giga-bits per second)). (The ebay product with the 140mhz spec. is confusing, but not necessarily "incorrect". It specifies "bandwith" as frequency (read mega-hertz, where hertz=cycles per second). The data rate that can be transmitted within a give bandwidth is a function of the modem design, algorithms used, etc. so, for HDMI, the bandwith doesn't tell us much whereas the bit-rate does. Check the "monster high speed" thread in this section and you'll see their suggestion that a 2.23gbps bit-rate is required for 1080i/8bit/60Hz signal; a 4.95gbps bit-rate is required for 1080p/8bit/60Hz signal, and a 10.2gbps bit-rate is required for a 1080p/12bit/60Hz signal. Now, the highest standard specified by ATSC for HDTV is 1080p/8bit/30Hz (? on the 8bit color depth) which would seem to imply that a cable or switch with a bit-rate of 1.65gbps should be more than adequate for signals within the normal home system.

Whew . . . ..!

Monoprice has a nice 3x1 with remote for under $50. http://www.monoprice.com/products/product.asp?c_id=101&cp_id=10110&cs_id=1011002&p_id=3029&seq=1&format=2&style=

Sure enough, Ram has the Gefen 3x1 with remote (and 3 HDMI cables) for $269. http://www.ramelectronics.net/html/EXT-HDMI-341.htm

I think I'd go with the monoprice.

Sorry, but I wouldn't recommend taking Monster's marketing pitch as a reason to buy anything. I would recommend ignoring everything you see on Monster's web site, however. These are products that exist only because of marketing - not because of need or merit.

Wasn't in any way suggesting to actually buy something from Monster.
But it was a pretty good and simple compilation of bit-rates required to transport various HD data streams and was in agreement with several other sources.

Yes but the point is that any and all brands of HDMI cable are capable of transmitting the currently used bit rates. It isn't necessary to have a cable that is "certified" for a given bit rate.

In general, true. Now, for the bad news, which I just came upon over the past few days:

1) For short cables (6' - 12') just about any cable will do up to 1080p/30.

2) For the longer cables (50'); not all products being sold today will work at the highest bit rates, resulting in loss of pq or even no picture at all. (example, Gefen's low cost 50' HDMI cable is actually only speced at 1080i).

3) And now for the really bad news: HDMI 1.3 defined two categories of cables: Category 1 (standard or HDTV) and Category 2 (high-speed or greater than HDTV) to reduce the confusion about which cables support which video formats. So, unfortunately, Monster is actually doing what they do best - great marketing - no lies, great use of facts, and giving some consumers a good reason to spend more money.

ps, I bought my last two HDMI cables from monoprice.

On a related note, are there adapter cables that will allow multiple HDMI sources/inputs into a single HDMI output?

My TV is 25 ft from my rack and my cables are integrated into the walls. I have a single HDMI cable running from my components to the TV which has worked fine with my single HD source (DirecTV). Now I want to get a HD DVD and possibly a PS3, so I'll need to add more HDMI inputs and don't want to run more cables through my walls.

Thoughts on an adapter cable vs. a switcher? Thanks.

Take a look at the Oppo 3x1 switch here: http://www.oppodigital.com/hm31/

Thanks for sharing that.
The switcher looks nice, but at $99 I was hoping to find something a little cheaper. I don't want to sacrifice picture quality though, do you think there are alternatives to the switcher?

Found this unit on ebay would appreciate any input on its quality

www.monoprice.com They are reasonable and should have what you need.
