Why is the resolution limited at 90hz?
There should be plenty of bandwidth to run 2x2560x2560 at 90hz. That should only be ~28.3gbps, which is less than dp 1.4 max of 32.
And it’s less bandwidth than a 4k monitor at 240hz, though that requires DSC.
Based on Wikipedia I think the unit is milligals, where a gal is 1 centimeter per second squared.
That is a bit of an odd unit where g is ~980,000 milligals.
So these changes are extremely small.
So then the total variation is all within about 0.02% of gravities normal value
