Question: How long is the delay when switching between two different feeds? and what is displayed on screen in the interim? black screen? snow?
Document: I just received this product.The LED blue lights are too bright. I covered with black electrical tape and pierce a small hole for visual reference.Or you can just remember which of your equipment setting is for &#34;in&#34; and &#34;out&#34; position.The button seems kinda flimsy, I don't know how long it will last with constant or daily pressing (switching).
I think the issue was with both products because last week, the Sewell stopped working!! It does not recognize the laptop and all I get on the TV black screen when I switch to the laptop. ** Overall, a very disappointing product and 1st time experience with Sewell product line! (giving it two stars because of the easy no-brainer setup)
Great little switch... I use it to allow two different computers access to a big screen monitor, and it does the job perfectly.
This works great for switching the outputs on my XBox. I have a Halo gaming area and a Kinect area which are in two different rooms. This allows me to have the Xbox direct to either so I can easily switch from the living room to the game area. I would say that the display usually goes a little wonky when you switch the outputs to different sized TV's. But a quick restart of my Xbox fixes that right away.
I only have one HDMI connection on the back of my TV. This works as a splitter / switch. I use it to switch from 2 different components. The lights are bright. Nothing a little black tape won't solve. Does what it's supposed to do. What more can you ask for.
Which I thought would have been a issue with using long cables, but I can't tell any difference in the screen refresh rate, which is very important for first person shooter games.
I previously bought a different HDMI switch that broke after not too long. This switch is much sturdier and great quality. My one issue with it is the bright blue colored LED. Its so bright that I had to put some tape over it, otherwise I could see it glowing behind my TV. it would also be nice if the colors were different for each input, but they are both blue. All around a good switch.
This is just what I was looking for! Something that had minimal ports for an easy fix to my 1080p HDCP handshake problem. Recently when I accessed my PS3 the screen would go black then come back consistently and randomly. I needed a cheap fix so I did some research and purchased this switch ASAP. It has been working superb and no more blinking screen (now I can watch my Netflix and play games without getting annoyed).
Does exactly what it says it does in the description with no fuss. Cheap easy solution for switching computer between monitor and big screen tv.
I wanted a device to switch my Comcast cable box between 2 TVs. A remote activated switch would not work but this mechanincal one does. I now have 2 of these for 2 different cable switching functions.
Answer: minimal time, if any.  black screen.
