Is it safe to leave my Spectrum Smart TV open for long hours to display my artworks and photos?

And no, im not talking about the Spectrum app.

Why don't you just contact their Customer Service? They have an online chat feature. https://www.evervuetv.com/contact/

It won't hurt anything. Just be sure you aren't running your TV at full brightness. Set the backlight no higher than half (50%) of maximum, and the brightness and contrast no higher than 60%. The lower the better, as long as the image looks good.
