The price a little shocked, but the switch is exactly what I was looking for

While there are also cheap Y-cable and splitter that can split the screen in two devices gelichzeitig supposedly, but in practice it has the problem that the signal is vernudelt and / or the handshake (EDID) between the receiver and 2 screen equipment fails ,
Therefore, I looked for the manual variant in which you can either switch to Monitor 1 or Monitor 2 and am finally has shared with the offered Umschaltsplitter.
In the photo the switch acts indeed huge, but in real life it's just a mini component, which takes away little space.

Tip: Also order a short HDMI cable to keep the total cable length of Bildquelle-> Switch-> Monitor as low as possible. Background: The longer the HDMI cable, the more the likelihood that signal losses. My experience: Depending on the quality of the cable and the devices used, so it can be critical from 7m ,. My PS3 creates example at 10m length only a resolution of 720p on my PC monitor.

Note: The processing is a little sharp, but that does not really bother.
