Hello Bostjan:
If the LED monitor runs on mains voltage, then
it must be certified by an NRTL.
If it runs on low voltage, it need not be certified
by an NRTL. But, I would get it certified anyway
as it is easy, not time consuming, and cheap. And,
it avoids any problems.
The UL-recognized LED panel is of no value unless
you certify the whole display.
Best regards,
Rich

Dear Experts,
We are just approving one product for US/CAN market that comprises LED
monitor. Would you consider LED monitor as a critical component and
ask for NRTL approval? There is no back-light inverter inside and
therefore no hazardous voltages.
LED display panel itself is UL approved. Is that enough?
Best regards,
Bostjan
