To Next PageTo Next PageWhy does my Samsung QB65R Digital Signage say Not Optimum Mode?
The 'Not Optimum Mode' message appears when the signal from your graphics card surpasses the maximum resolution and frequency supported by the Samsung Digital Signage. To resolve this, consult the Standard Signal Mode Table and adjust the resolution and frequency settings to align with the product's specifications.
What to do if my Samsung Digital Signage displays 'No Signal'?
If 'No Signal' appears on your Samsung Digital Signage screen, ensure the product is correctly connected with the appropriate cable. Also, verify that the source device connected to the display is powered on. If you're using an external device, the display may not work properly unless you turn on the HDMI Hot Plug function.
