Since everything got really slow after I hooked up my 2016 MacBook to the Ultrafine 4K display I am thinking of switching back to Windows again after 1,5 years with Mac OS. I seriously don't want to pay 2500-3000 Euros for a MBP just to drive the monitor while maintaining an acceptable overall performance. The problem is: I LOVE this monitor. It is the perfect size for me and the extra resolution (compared to standard 4K) is very welcome. There simply aren't enough 21-22" 4K displays out there. They usually start at 23,6" and then they offer only standard 4K resolution. So I'd really like to keep the Ultrafine 4K, but I am worried that it won't work under Windows with full resolution AND 60Hz. Wikipedia says that Thunderbolt 3 / USB-C only supports a resolution of up to 4096 x 2160 and the Ultrafine 4K has a higher vertical resolution of 2304. So I wonder if there is some magic going on like when you use the Ultrafine 5K on a Mac and two lanes are used to transfer this huge resolution to the monitor. If the same would be the case with the 4K monitor it probably won't work with Windows in full resolution.
