    Negotiation of the resolution and refresh rate between the monitor and the computer is reliant on the connection. Using an older analog VGA connection is much slower than using newer digital standards. The two quickest ways to get rid of delays when changing desktop/game resolution:

    1. Have the graphics card do any required scaling to the monitor's native resolution.
    2. Use a newer digital connection like DVI that negotiates changes faster.

    Desktop LCD monitor flickering from dark to faint display of the screen
  • Thierry Lam

    I have this 19" LCD Viewsonic monitor from 2005. Yesterday, it starts flickering from dark(as if it is turned off) to very faint display of the screen. After I shut down my computer while the monitor is still plugged in, I still observe that behaviour. My display and power connections are secured. I don't believe I have any power issues at my place. Does that mean that the monitor is dead and it's time to get a new one?

    Well, sounds like a hardware issue to me, but to be sure, you should try plugging it into another computer and seeing if the issue persists.

    There is a stupid little controller board (lcd inverter) that tends to fail, and cause this sort of a problem...I've seen it a lot with laptops, but I've never seen someone replace one on a monitor...The price point on the board is high enough that it's not usually worth it, and it's totally not worth it if you have to pay someone else to install it.
