so I just did an OS format on my Aspire 4930..
I formatted Vista to XP because of obvious reasons.

but, after I installed all my drivers proper,
everytime at startup, my monitor would blink once to black,
but only about one second, even less..

it would not blink again for the rest of the session though.
but, when I uninstalled the VGA Intel driver to see if it had any effect,
the monitor didn't blink. it seems that the driver is the problem, yeah?

but I tried installing two versions and they're just the same.
what I want to ask is:

1) will it have any long-term effect?
2) is the monitor adjusting to anything; refresh rate, etc?
3) can I repair this?

thanks very much in advance..:)

Quick summary and context: the one-time black blink at boot after installing the Intel display driver on an Aspire 4930 is most often a harmless result of the graphics driver taking control of the screen hardware after Windows starts. ’s test (blink disappears when the VGA driver is removed) matches a driver-origin cause, and correctly pointed toward a normal display reinitialization rather than a failing panel.

Practical checks and steps to reduce or eliminate the blink:

  • Verify the installed driver (Device Manager → Display adapters) and note the driver date/version.
  • Try the Acer-supplied XP package for the 4930 first; OEM packages sometimes include initialization routines tuned to the laptop panel. If you used a generic Intel package, compare with the OEM package.
  • Do a clean driver install: uninstall the adapter, check “Delete the driver software for this device,” reboot, then run the chosen installer as administrator.
  • If the blink is only cosmetic but unwanted, experiment with a different stable driver version (older drivers sometimes avoid a brief reinitialization) rather than repeatedly switching settings.
  • Test with an external monitor. If the external display also shows the same single blink, the behavior is software/driver related; if only the laptop panel blinks or it happens repeatedly during use, investigate hardware (cable/inverter/backlight/GPU).

When to worry: a single brief blink at boot that never recurs during normal use is not harmful. Escalate only if the blackout becomes frequent, happens while working, or brings visual artifacts (lines, color corruption, intermittent signal)—those point to hardware or GPU problems and deserve a deeper inspection or service. Credit to for the diagnosis and to for the clear reproduction steps that made this easy to pin down.

Yes - the monitor is adjusting refresh rate from VGA to whatever setting the now available Registry tells the driver.

Nothing wrong; nothing to repair. My main monitor (LCD) does this.
