Frequently asked questions

  • Monitors
    • Why does white not look white in my picture?
    • Adjust RGB color or select desired color temperature.

    • Why is my screen image not centered or sized properly?
    • Adjust H-Position and V-Position or press hot-key (AUTO).

    • Monitor power-light indicator flashes from green to orange constantly and there is nothing on the display. What is the reason of this?
    • This indicates an internal failure inside the monitor. Please visit www.aoc-europe.com and refer to our support page for more information how to contact our technical support.

    • Monitor power light indicator changes from green to orange and there is nothing on the display. What is the reason of this?
    • Check to see that the computer is not on power-saving mode by pressing any key or moving the mouse. Then if there is still no display, this typically indicates that the monitor is not receiving a video signal from the video card in your computer. You should verify this by trying the monitor on a different working system, when you plug the monitor into the computer you should get a display…if the monitor still doesn’t show an image on the different system, this indicates an internal problem with the monitor. Please visit www.aoc-europe.com and refer to our support page for more information how to contact our technical support.

    • Is there anyway I can adjust the blurriness on my screen?
    • Unfortunately our monitor doesn’t have any external control to adjust the focus of the monitor. Try to change to a different resolution or refresh rate or try adjusting the brightness or contrast, if this doesn’t help, this indicates an internal problem with the monitor. Please visit www.aoc-europe.com and refer to our support page for more information how to contact our technical support.

    • Why is the display of my monitor fuzzy and it has ghosting & shadowing problem?
    • These problems are caused by using an extension video cable or switch box. You need to plug the monitor's video cable directly to the video card connector on the back of your computer to obtain the best picture quality from the monitor. Also make sure that all the pins of the monitor's video cable are in good condition.

    • Why does the display on my monitor appear to flicker, bounce or wave?
    • Move electrical devices that may cause electrical interference as far away from the monitor as possible. Also use the maximum refresh rate your monitor is capable of at the resolution your are using.

    • My display is missing one of the primary colors or it is showing tint color (pink, green, blue).What is the reason of this?
    • Check the pin connector of your monitor video cable, verify that there are no damaged or bent pins, if everything looks fine; then this would indicate a failure inside the monitor. Please visit www.aoc-europe.com and refer to our support page for more information how to contact our technical support.

    • How can I minimize the flicker on my screen?
    • Change the refresh rate of your monitor

    • I have color spots on the corner of my screen. Is this normal?
    • No. You should try to activate the Auto-Adjust feature. If this does not work, please visit www.aoc-europe.com and refer to our support page for more information how to contact our technical support.

    • My screen has gone completely black but the power light is still on (green). What is the reason of this?
    • Make sure that the signal cable is properly connected to the monitor and is securely inserted into the video card in the back of the computer.

      Make sure that none of the pins on the signal cable are bent or broken. (It’s normal for some of the pins to be missing).

      Make sure that your computer is turned on and working properly. Your monitor could be waiting for a signal from your computer.

      Try turning on your computer and monitor in a different sequence.

      If none of these suggestions help, please visit www.aoc-europe.com and refer to our support page for more information how to contact our technical support.
