    Hello,

    I am looking into plugging a eGPU to a laptop screen and I was wondering if someone has actually tried any USB 3.0 framegrabber HDMI input that provides live video with no lag (<1ms or something like that, low enough for playing)

    I have seen Express card based HDMI inputs doing the trick pretty decently so I suppose is theoretically possible to do it through USB 3.0.

    I know it is not going to be the most cost effective solution but it is a question that is constantly bugging me and is extremely difficult to find any confirmed information on anybody having actually tried to use a USB 3.0 based framegrabber for live gaming, most of the information I find is about recording gameplay.

    So, has anybody actually seen this setup working in a live gaming situation?, if so, which USB device was it?

    USB is not a proper low latency bus with large transfers, I don't think you will ever find a device that will pass the video game test.

    The express card models that work well are using the pci express bus.

    USB - huge transfer speed, huge lag. For transferring files it is OK, for transferring live video with no lag - not really.
