I need a cable or box to clone 1-HDMI to 2 Monitors

[thecomputerguy]

I was looking on amazon for a HDMI splitter similar to how VGA has a Y cable to clone/mirror one VGA connection to two monitors. i.e. http://www.amazon.com/Cable-VGA-HD15-Male-Female/dp/B000BSHI4C

The idea is that the user has a laptop that he will plug into a monitor via HDMI then he wants both monitors to be a clone of each other. One he looks at, and one is facing the other direction for the client to see, and the laptop display is closed.

Amazon has a ton of "Switches" (http://www.amazon.com/eForCity-SWIT...&qid=1428363532&sr=1-1&keywords=hdmi+splitter) but I don't want to "Switch" the live connection to the #1 or #2 or #3 or #4 HDMI output, I just want the image cloned/mirrored at all times.

- I want to avoid adapting the HDMI into VGA and use his existing cables
- His new laptop does not have VGA, only HDMI

Anyone have a recommendation?

Just plug the monitor into the HDMI port on the laptop and go to the 'Control Panel\All Control Panel Items\Display\Screen Resolution' and set the 'Multiple displays:' drop-down to 'Duplicate these displays'.

I have 1 HDMI port and a total of 3 displays.

1-Laptop
2-Monitor(1)
3-Monitor(2)

The 1xHDMI on the laptop needs to go from the laptop to 2xExternal Monitors

A splitter like this?

Yes but I am in the US so I need to find something like that on Amazon.com

But I am looking for the full simultaneous, synchonrized display.

Did you look up HDMI y-cable?

 

[thecomputerguy]

I did and found a couple but the reviews for them are AWFUL, and I was hoping someone has some personal experience with one.

There is nothing special about a video splitter. It literally splits out each conductor. The reason why people have problems with them is usually because they have no idea what they are doing. Since a basic splitter does no signal manipulation using one on a low end graphics chipset usually causes problems. I've seen people trying to drive two 22" vga monitors from a laptop that had an Intel Mobility video chipset. You need a real graphics chipset to do these things. There are also limits to the monitor size. So from a laptop I'd recommend something from aten or geffen.

Depending on the size of monitors (thus resolution)...and your graphics cards....can get inexpensive passive splitters...or a powered splitter box.

This is HDMI you are talking about and it's a two way conversation between the source and monitor. Trying to use a plain old splitter just doesn't work worth a darn.

This is like what you want.

+1 Mercenary. Most people don't realize that the receiving device on the other end of the HDMI actually talks back to tell information like max screen resolution, power on, etc. So while splitters may occasionally work, they more often cause issues like screens blacking out at random because they are getting signals from the other TV/Monitor that they shouldn't.

I'd try something like this:http://www.cableleader.com/hdmi-amp...m1i0qd8e_TqeZuO8R8oo_vMNg4hOuVQaP4aApTi8P8HAQ
which most likely blocks those return signals.

Problem even with that splitter is it won't let you play any type of copy protected stuff. The source has to talk to the TV and get the proper response that it's okay to play the copy protected stuff and if it doesn't get the correct response it would play. The active splitter like I link does all of the talk back to the source so you have no problems. Well, I think the one I link does that, some don't.
