That depends.  I use 'vintage' IBM PS/2 server machines with IBM XGA-2
monitors from the same era for ham apps.  This is some of the best
shielded computer gear ever made, and I have yet to detect any hash
from this stuff.  Of course, the new shack and R390A are both still
disassembled, so I haven't tested that particular equation.

Botton line, consumer grade monitors tend to have poor shielding,
despite what they want you to think.
