Even with my superior eyesight and phenominal brain processing power you know I possess, I cannot see the refresh on my monitor at home.

And I don't get headaches when I work in front of it for one of my 10 hour sessions on Sentience.

Then again, the monitor is quite good for such a standard name (Belinea). So good, that I didn't get a new one when I bought a new machine, even though it's three years old now.

PS - If you're in (or can get to) an open plan office then look down the office at all the machine and blow a raspberry.

Cool as!!
