That is indeed MildlyInfuriating - sucks dude!
My work issued Lenovo laptop only does 1440p/30 4k/30 with it’s built in HDMI and, for reasons that make sense only to Lenovo, also is 30hz capped when connected to their USB-C and Thunderbolt dock for who knows why. Drives me crazy.
Love this. Apart from hosting an instance, what are you using it for? Self-cloud?
