I need to display my computer's HDMI output in 4 diferent screens?

What you might want to look for is an HDMI splitter. They aren’t cheap.

Here is one that I think is what you are looking for.

@rpmpseudonym That seems fairly cheap, actually.

There is no need to split the signal. Just buy a graphics card that supports HDMI and VGA port .Connect VGA port TV.There are special cables for connecting TV to computer(I don’t remember the name though)!
For the computer matter, you have to create three subnets and create a bridge between these 2 computers.

@gnsagar27 I don’t have any expansion slots on my computer, it is just a single signal going out to the TV

@rpmpseudonym I think that will do it! According to the description it will down-regulate to accommodate various display sizes, which is what i need! Thanks

I recommand you to invest in new motherboard or new computer. There is nothing you can do with your current computer!

@gnsagar27 so you don’t think rpmpseudonym’s suggestion will work? why?
