IT worked. The "Portable Audio Video Capture Cards HDMI to USB 2.0 1080P 4K Record Via DSLR Camcorder Action Cam for High Definition Acquisition, Live Broadcasting (USB 2.0)​" off amazon for $20 bucks actually worked, and quite well too.

I have a couple of Elgarto Game Captures, and have used a Avermedia LiveGamer portable too. One of the them can do 60fps or should be able too, it won't on my hardware. The other two are 30 Frames Per Second Max anyway - like this. All thee named brand captures will not run if the laptop is on batteries. The "Portable Audio Video Capture Cards HDMI to USB 2.0 1080P 4K Record Via DSLR Camcorder Action Cam for High Definition Acquisition, Live Broadcasting (USB 2.0)"  does. Colour is ok, I htink this might be the the the BEST of my usb capture devices. Set up on this laptop in the café at lunch no problem. 

I doubt it will do 4k (or maybe down sampled) but for $20 its fantastic!

WIN! More tea? I Think so... Also it wasn't $20 it was $14.98
