Capture Card Stream to Desktop

I have recently set up 5x70" TVs in profile along a wall running from two AMD HD 7770's. I have a capture card in the computer to allow for video input from smaller devices (such as a laptop or Apple TV) to allow them to display to all 5 TVs. When doing this, there is a definite lag in the display (screen tearing and very choppy video) and I was wondering if anyone knows of the best way to improve the video quality to a fluid stream. PC Specs are below.

AMD 3.3ghz 6 core bulldozer
Sapphire Radeon HD 7770 x 2
Corsair Gold 850w PSU
8 gigs of DDR3 1333

The ram is low, but the initial use of this computer was a normal work station.

Any suggestions and theories are greatly appreciated. I will gladly post any pictures or try any ideas anyone may have.

  1. Don't the TV's have their own inputs so you can connect directly to the TV from the laptop/apple?

    That may work with one TV, however, I am using 5 for one very large display.

    I apologize, I should have added further clarification. I also want to use this fantastic set up to possibly game or watch movies on during non work hours/weekends. I have also been requested to make sure that it has the ability to stream from other video sources.
  4. I don't think you are going to be able to use the PC as a pass-thru for this. You need a device that can split and magnify the signal to all the monitors.
