Hello everyone, I just received my new X1 Carbon 6th gen and I really like it a ton so far, but yesterday I was trying to use it for a presentation at work and have found some really inconsistant behavior with the hdmi port and projection mode. If I reboot the laptop and plug in the projector hdmi I can get screen duplication to work perfect. If the laptop goes to sleep or if I switch my mode to laptop only I can not get the hdmi port to work again until I reboot or strangely if I plug in (but not use) a hdmi dongle to one of the usb-c ports. I've checked and all my drivers and firmware are 100% updated. Any ideas or tips? Thanks!

Update: I applied the BIOS update posted in the fan noise thread here: https://forums.lenovo.com/t5/ThinkPad-X-Series-Laptops/X1-Carbon-6th-gen-Fan-Noise/m-p/4054791/highl... and it appears to have also resolved my hdmi issue. Win win!
Update 2: Nevermind, same bad behavior returned again with 1.15 BIOS (but at least the fans are quiet now).
