Technical support 

26.  Trouble Shooting 

26.1.  No image on the screen 

➢

 

If G900 output resolution is 4k/2k/60Hz and the monitor can’t support 4k input, user will see no 

display image in the monitor. 

➢

 

Please use remote controller or front panel output selection keys to select [1080] or lower output 

resolution to let display device be able to support it.   

➢

 

Please check input/output LED indicators and make sure all the signals are correctly connected. 

➢

 

If 

user still can’t see the image, please click [Menu] key to activate OSD. If user can see normal 

OSD, the system should be normal. Please click [INFO] key to check input and output timings.   

➢

 

If user still can’t see the image, please change signal source, HDMI cable or display device to 

find the root cause of the failure. 

➢

 

HDCP may be the reason for no image. Please make sure display device is HDCP compliant. 

➢

 

Many HDMI extenders can only support up to 4k/2k @30Hz. Please select correct HDMI 

extender based on your requirements. 

26.2.  Intermittent or loss of input signal 

➢

 

Check the HDMI cable quality and make sure all cables are fitted correctly. 4k/60 signal requires 

4k/2k certified cables. 

➢

 

Cable length: Connecting cable length should be as short as possible. Replace a short cable to 

verify the possible root cause. Usually, the longest standard 4k/2k HDMI cable is only up to 10m. 

➢

 

HDCP compliant issues: If the input source or the monitors are not HDCP compliant, it is possible 

to stop G900 from negotiating HDCP link and show intermittent, abnormal or no image. Please 

check HDCP condition in signal source or display device. 

➢

 

Resolution issues: check if signal source and connecting cables can provide source signal 

supported by G900. 

➢

 

DVI/HDMI signal compatibility: some display devices may only support DVI video signal. The 

default output is HDMI. User can change output with DVI format through [Options]

→

 [Setting]

→

 

[DVI]

→

 [On] to test it. 

➢

 

Usually, to swap with different cable, output channel, signal source and monitor can verify the 

root cause for the failure.
