Re: computer screen blink

Show key headers only | View raw

Hi,
you may fist determine if it is a hardware issue or a software issue.
Some Mac screens are known to flicker after a while.
What is your computer ? Can you boot on Windows/MacOS to see if the same thing happens ?
Knowing your hardware may help a lot.
hth,
Jerome
