6FT 2TO1 HDmi Switch

6FT 2TO1 HDmi Switch Review

Available at Amazon Check Price Now!

I got this HDMI switch about over a year ago and its still working like its brand new. I was slightly unsure at first, especially when It was around 80 Bucks for it about October 2008. I have a 24″ 1080P monitor for my PC, Xbox360 and PS3. So I wanted something that I can plug everything in and then hit one button to switch between my systems without having to unplug and replug things in the back of my monitor. FYI my Monitor has DVI and HDMI switch in the back. My set is My PC is hooked into the DVI and Both my Xbox360 and PS3 are hooked into the switch via HDMI. (DVI and HDMI have no visual differences, only thing is HDMI can transfer audio, but i use optical for my audio for ps3 and xbox360) Anyways the BIG difference with this unit is that it IS HDCP applicable! What does HDCP mean? HDCP is licensed by Digital Content Protection, LLC. So what that means is that ALL and I mean ALL protected/licensed media, music, movies AND games have a protective code in them that needs HDCP to decode it for displaying. What would happen if you used a NON compliant HDCP switch? Well you would get a blank screen. No way to fix that except get an HDCP compliant switch. So that was my biggest worry but I did my research on this switch on other websites to make sure it would work, and it does beautifully. No loss of quality on either my xbox360 or my ps3 its just a simple switch, small and compact as well. If I ever needed another switch I would get this one, its way more inexpensive than many others that are out there that don’t do anything more than this does unless you are looking for more than 2 HDMI ports.

This is my third IOGear switch over the past 8 years, and I wanted something to allow me to use my work laptop with my new Dell XPS9000 with a 22inch 1080P monitor. My laptop has a DVI port and the Dell has an HDMI. I opted for the HDMI KVM switch based upon the reviews and the capability to use USB switching as separate instances not tied to the KVM switching. I had to get a DVI to HDMI adapter for the laptop, and that works great. With this switch you can switch just the KVM instance, the USB instance, or all instances to whichever computer you choose. The only downside is when I switch all instances to another computer, my speaker makes a pop noise that drives my dog crazy. Aside from that, this is well worth the money and I highly recommend it.

HDMI Switch: Insider’s Guide

June 29th, 2010

Background:

The High Definition TV “experience” continues to drive manufacturers to offer truly digital devices. The days of analog video interfaces are limited. In previous articles, we touched on HDMI connections. It is clear that HD sources such as DVD players, Cable settop boxes, satellite boxes are transitioning to the HDMI standard. It is inevitable that future HD sources such as HD DVD players (HD or Blue Ray), and Playstation 3 will utilize HDMI as the interface standard. With all these new HDMI source, how does one get the desired input to the HD monitor? In this article, we will get into the details of such a device: the HDMI switch.

What is a HDMI switch:

A HDMI switch allows the end user to select multiple HDMI sources, such as DVD players, settop boxes, into 1 HD monitor. The basic models available are 2×1 HDMI switch, which simply means that there are 2 inputs and 1 output. The 2X1 HDMI switch allows the user to switch between 2 HDMI sources. There are also 4×1 HDMI switches available which allows the user to select up to 4 HDMI sources. By the way, we highly encourage users to select 4 port model for future expandability.

Why do I need a HDMI switch: Anyone who has a HD monitor with less than the desired number of HDMI inputs can use an external HDMI switch to expand the system.

What features do I look for in a HDMI switch:

- Expandability: 4 ports devices are recommended for future expandability. If you use a 2 port, then you have no expandability. It is likely that future HD sources such as games stations, HD DVD player/recorders will utilize HDMI.

- HDCP transparancy: any switch must pass HDCP data between source and monitor.

- Backward compatibility with DVI-D: There is a mix of both HDMI and DVI-D devices in the field. Users should select a HDMI switch rather than a DVI-D switch since HDMI is backward compatible with DVI-D. With a HDMI switch., the user just chooses the correct cables needed; either HDMI or HDMI to DVI-D to customize to your system.

- Remote control: A remote control to select the desired channel is essential.

Design consideration of a HDMI switch:

HDMI is extremely high speed digital transmission standard with an aggregate data rate of ~4.95 Gbps. Jean Baptiste Fourier (1768-1830) showed that any signal waveform can be resolved into a summation of harmonically related sine waves. The amplitude of the sine waves can be determined by calculation of Fourier transforms.

So what in the word does some dead French mathematician have to do with the HDMI switch? Well, Fourier tells us that the waveform is a summation of harmonically related sine waves. Therefore, higher data rate, higher frequency sine waves. Incidentally, the frequency of the fundamental sine wave is ½ of the data rate. For example, the fundamental frequency of a 2 Gbps ( 50 %duty cycle ) square wave is 1GHz.

As data rates increase, every aspect of the switch design (every millimeter) becomes critical because the wavelengths of the signals approach the size of the components on board. The 3 critical parameters to consider are:

Impedance Match:

HDMI is based on a 100 ohm (differential) impedance. It is imperative that the switch be optimized to match this characteristic impedance. Any imperfections of the board layout will cause “reflections” which degrades signal transmission to the HD monitor. Think of “reflections” as signals that are lost between the inputs to the output. Utilizing careful RF and Microwave layout techniques minimizes these reflections.

Minimum Insertion Loss:

Signal loss should be minimized in order to maximize signal integrity to the output of the HDMI switch. Again, utilizing careful RF and Microwave layout techniques minimizes insertion loss.

Minimum Cross Talk:

With multiple inputs (up to 4), all potentially being active at same time, it is imperative that the desired channel not be interfered from any undesired channels. Again, careful RF microwave design techniques minimize cross talk.
