Dorectly from the Seura webite: "Designed for any outdoor location, Séura® Full Sun Series™ delivers 2000-nits, color-calibrated, for the industry’s brightest direct-sun outdoor TV. The weatherproof TV is built with Séura's proprietary active heating and cooling system and boasts specs of IP55 waterproof rating, -40° F to 140° F temperature range, full array local dimming, 4K UHD and HDR, and 2-year warranty."

Sounds like it can be in direct sunlight to me. And they do support their products IF there is an issue (and there hasn't been with any of my direct sun installs).

There is active heating and cooling built into the full sun models. They do have models for shade that are not meant to go in direct sunlight. I would think if you put the wrong TV in for the application (which unfortunately I have seen alot of). you would decrease the life of the panel
