> Why don’t they produce 5K/6K monitors that allow for 2x integer scaling?
Because 5K panels are probably more expensive to produce than 4K ones, and because that would only benefit Mac users since Windows can do fractional scaling just fine. I'm not sure about that but it might also be that not all GPUs used in PCs can drive monitors larger than 4K.
Even if Windows/Linux do fractional scaling fine, integer scaling is still desirable if it’s an option. Under both I still run into programs that botch fractional scaling some way or another, and given the proclivity of programs on both platforms to be built with oddball UI toolkits I don’t expect that to ever really fully resolve itself.
It’s one of the chief complaints I have with one of my mostly otherwise good x86 laptops. The 1.5x scaling the display needs has been a pain point on multiple occasions.
Why don’t they produce 5K/6K monitors that allow for 2x integer scaling? The $1,600 Studio Display is only $1,600 because it has no competition.
