A flickering display can be very frustrating but is often easily fixed. The flickering can be caused by a number of different issues outlined below.
Loose Connection
When inserting a cable into the back of your monitor, it’s essential to ensure it is fully plugged in. VGA cables, like the one shown below, are particularly susceptible to loose connections. Always ensure the screws are tightened if applicable.
The best way to test a loose connection is to completely remove the cable from the monitor and from the source device, then reinsert it on both ends fully.
Issues With The Input Cable
If the input cable you are using with your monitor is damaged, this can cause the display to flicker.
To verify whether the flickering is caused by the cable, use another cable with the monitor, or test the cable with another monitor if possible.
If the display stops flickering when using an alternative cable, this means that the cable is faulty and requires replacing.
Software Issues
Some graphics cards have drivers that are incompatible with certain monitors. Updating your operating system or the drivers themselves may fix the issue. Ensure that you install the correct driver for your specific graphics card.
If you are unsure which graphics card you have, contact our Customer Care Team.
Failing Graphics Card On Your PC
Graphics cards sometimes develop problems which cause flickering on monitors. You can check to see whether this is the issue by using the monitor with a different PC or source device or trying another monitor with the affected PC.
Electronic Interference
The presence of magnetic objects near your monitor can cause flickering. Always avoid setting up electronics near magnetised objects. Some power outlets may output electronic interference - try changing to an alternate power outlet to see if this fixes the issue.
Internal Issues
If you have checked the flickering isn’t caused by cabling, graphics cards, or interference issues, your monitor may have an internal issue. For assistance with any of your Kogan.com products please contact us via the Customer Care Centre.
