Monitor Heat Dissipation Help

I am calculating all the heat dissipation in my PLC control panel. The HMI monitor I have does not state the power dissipation for the monitor. Only the Power Consumption, which is not the same. The power consumption is 16W, so I can state for worst case the heat dissipation for this monitor is 16W.

A device will never dissipate more heat than it can consume. Can someone confirm if this is feasible?

the only good way is to measure the power. however 16 Watt seems fine, calc 75% to the inside and 25% to the outside. as this is in the front of the panel.

I would use the full 16 W to be safe. If you are so close the edge that 4 W makes a difference you are probably in trouble anyway.

Thanks for the support.
