FAQ
If your monitor goes blank or says “mode not supported”…
It is possible to set the output resolution to one that your monitor does
not support. In this case you my not get a screen. You can either keep
pressing the OUTPUT MODE button as it eventually goes through all
the available outputs in a circular fashion, or use 2-button “Quick
Select” combination to jump to a specific output immediately
If you are convinced that the unit is defective …
Do not open or try to repair the unit yourself. There are no customer
repairable items in the unit and you will void your warranty by doing
so. Contact HRT instead.
