Multi Video game connection

1. List all the video specifications of the games machines
2. List the video inputs of your display device

You aren't looking to make a 'splitter' - you are looking to make a 'switcher'

 

The Red, Yellow and White plugs are composite video (with audio) and a totally different signal than that created over HDMI. Unless you have a monitor that can accept a multitude of different signal types (some modern TV sets actually do) then you'll have to convert the signals to a single standard that your monitor CAN accept.

As stated though, a decent TV set will accept composite, HDMI, VGA and SCART - possibly more - which would cater for all your gaming signal needs and all you'd have to do is use the TV remote to select the required signal source.

Worst case you'll need to convert only one of your gaming sources to one that a TV could accept.

Problem solved....

 

Switching between composite signals is easy - you can even use a multi-pole rotary (or push-button) switch to do this.

you could also purchase a composite switcher:

If you also purchase a Composite Video-to-HDMI converter like one of these:

you're set to go.

Note that the converters linked to are composite-to-HDMI whilst many cheaper converters are labelled as such but are the OPPOSITE i.e convert HDMI to Composite so take care when ordering.
