Hello all. I have been looking at possibly purchasing a ROKU TV to replace a 14 year old Sony Bravia LCD in our bedroom which has a streaming stick attached already which works extremely well as long as the TV lasts which could go anytime due to age. I would like to know about auto brightness in the ROKU TV's and is there a way to turn off this function. I like to set my TV on the brightness level I like for all my streaming Apps and not change regardless of the amount of light in the room or picture mode. I also use Movie/Cinema on my TV's and customize and fine tune the picture settings. Thank you for any info that you can provide about turning off auto picture brightness.
Respectfully,
Don
