Can i use a LCD tv for watching normal tv,use with ps3 and computer monitor?

Question

Like to do those 3 thing at once?

Answer 1

If I understand your question you want to split the LCD monitor into 3 or more equal size displays. If this is what you want you need to buy a special piece of equipment to do this.

Here is one unit.

It takes 4 inputs and outputs onto one monitor
