How to fix a Polycom GS-27 when nothing is displayed on the screen?
- AAndrea PorterAug 2, 2025
If nothing is displayed on your Polycom Monitor, verify that the power cord is correctly plugged into the power outlet. Ensure the DC switch on the bottom of the monitor is turned on, check your power cable connection, and press the power button. Also, check your signal cable connection. If the monitor is in sleep mode, move the mouse or press any key on the keyboard. Make sure your computer is turned on. If the signal cable that connects your monitor and external device is dislocated or disconnected, check the cable and reconnect it. If the signals transferred from your PC are outside the monitor's frequency range, consult the 'Product Specification' section of the manual to set the appropriate frequency.
