UPDATE #2 05/04/17: The issue was a bad Intel Graphics driver. for some reason, the driver that fixes this issue came out yesterday but is marked as "Previously Released" instead of "Latest" on their Intel Graphics Iris Plus 640 driver page. Download version 15.45.18.4664 to solve issue.UPDATE 05/04/17: Received replacement from Amazon, problem still persists. Currently taking part in discussion on Intel's community forums and will update this review if any progress is made.ORIGINAL REVIEW 05/03/17:A small group of people, myself included, have experienced a bug when running at 4k@60hz either via USB-C or HDMI 2.0 where the video loses connection briefly and then returns (also cutting audio if being sent). Intel has assured us that the latest BIOS and HDMI Firmware do not have this problem and have been tested for consistency. I really hope this is just a lemon but it also raises quality control concerns if I'm not the only one who has this problem. Regardless, I will replace said device and update this review once I test it out.Current Configuration:Windows 10 Pro Creators Update (ver 1703)BIOS: BNKBL357.86A.0045HDMI 2.0 Firmware ver 1.66Crucial 8GB (4GBx2) DDR4-2133 (CT2K4G4SFS8213)Samsung 250GB EVO 960 NVMe SSD (MZ-V6E250BW)Samsung 40-inch 4K TV (UN40KU6300)AmazonBasics HDMI 2.0 Cable 6ft (HL-007306) - Used two of these to see if problem persisted after changing cable
