Nothing compares to the old school large dell lcds. I had one years ago that was a furnace.
Yeah it does emit a bit of heat. I think around one or two hundred watts? I haven't measured it directly. I have a mini split air conditioner in my home office.
Makes sense, also See comment about energy consumption of 8k TV above.
The comment above has very wrong numbers, by the way, typical consumption for the whole device should around or less than what that poster claims is drawn just by the CPU!
