I am using the trial version of vmix (14 and now 15) with an asus thunderbolt laptop, aja 4kio and a BM ultrastudio (small one). I am having issues with the output latency. I am rigged up for testing thru my HDMI TV (similar latency with Sony pro monitor). If I output thru either the aja or BM I am getting 6-8 frames of delay (even on clip playback) longer on an HDSDI camera input (Canon XF-305). If I use the laptop HDMI output I am seeing 2 frames of delay (approx). The laptop is fine for testing but I really need to use a dedicated hardware output as I hope to use the system for high end corporate/broadcast events. I used to have a Newtek Toaster which always had at least 6 frame delay and its too much for projectors, I regularly work in broadcast and see 1 frame from the higher end switchers. I understand this is a 'cheap' solution, but have seen others doing the kind of jobs i believe would need a very low latency. I have disabled de-interlace and cannot see what else to try to reduce the latency further.

Any thoughts?
