Selecting The Adapter
Before purchasing the adapter it is important to check the following information
- What display outputs does my device have?
- What display inputs does my monitor have?
- Is the adapter I am selecting confirmed to be compatible with my device?
Please remember to check the resolution and refresh rate of the monitor before selecting the adapter.
The resolution and refresh rate will be limited by the source device, the cable, the monitor and the adapter if one is being used. Whichever of your components has the lowest maximum refresh rate will set the maximum refresh rate of your monitor. For example, if you are using a computer that outputs 120hz@4K, and you use a VGA cable, you will be limited to 1080p resolution at 60Hz by the cable. You can check the limits of common cables below:
- HDMI 1.4: up to 4K@30Hz, 1600p@75Hz, 1080p@144Hz
- HDMI 2.0: up to 4K@60Hz, 1440p@144Hz, HDR
- DisplayPort 1.2: up to 4K@60Hz, 1440p@144Hz, HDR
- DisplayPort 1.4: up to 4K@144Hz
- DisplayPort 2.0: up to dual 4K@144Hz
- USB-C: Depends on device
- DVI: up to 1080p@144Hz — does not support audio
- VGA: up to 1080p@60Hz — does not support audio
Confirming The Adapter Is The Issue
Please ensure that you have tried the troubleshooting outlined in My Monitor Has No Power / Display to confirm that there is no issue with the monitor or the device you are connecting before proceeding.
Please try using the adapter on another compatible device, please note that Apple products do not use common adapters please refer to our guide for Apple adapters How Do I Connect A Mac Computer To My Monitor?.
Updating The Drivers On Your Device
Windows operating systems may require you to update your device to be able to use the connected adapter. If all the connections seem to be correct you may need to check that you do not require an update of your graphics drivers.
- Go to Settings (Windows + I) > Update & Security > Windows Update.
- Click Check for Updates
If the drivers are up to date please ensure that you have got the display settings on your device set correctly. Please ensure that you check that the resolution is not set too high for your Monitor by checking the resolution settings on another monitor or by booting the device in safe mode.
