I have a simple Form with 2 DataGridViews:
They share the same column headers for illustration purposes.
The bottom one has a slight configuration in the column header:
dataGridViewCellStyle1.Font = new Font("Segoe UI", 8.25F, FontStyle.Regular, GraphicsUnit.Point);
This is how its source looks like:

At 100% scaled displays, they both look great:
However, with a 2 display setup, being displayA 100% and displayB 250%: application started on displayA (100%), and moved to displayB (250%):
I wish to emphasize the column header's height and font here. In the upper grid, it's perfect, while the bottom one stays at the 100% scaled font.
If I remove the Font configuration from the bottom one, it scales perfectly too, just as the upper one.
How could I change font on the grid while preserve the high-DPI feature?
Slight addition: if I "pack" the grid into a panel, and change the font for the panel and removing the font setting from the header, it works between different-scaled displays.
Update
Also the scrollbar looks very weird after moving to different monitor (compared to ListBox):
