A:AnswerHello MP, This isn't exactly the same thing as an ultra built into the TV but it should be just as quick and snappy as the Roku Ultra. The Ultra does come with a better remote the Roku Voice Remote Pro (2nd Gen) and offers Dolby Atmos for TVs that support it.
A:AnswerYes this model does have a sleep timer, you can either do it in settings in the main menu or by pressing the * while watching something and pressing sleep timer.
A:AnswerHello MeToo, Unfortunately this model does not have Bluetooth but the new 2025 model thats coming out soon does have Bluetooth. The 50" is already out ( https://www.bestbuy.com/site/roku-50-class-select-series-4k-smart-rokutv-2025/6622476.p?skuId=6622476. ) I unfortunately don't have a date on when the 43" will be released.
A:AnswerHello JohnR, content that is not in native 4K resolution will be upscaled on a 4K TV. 4K TVs only output 4K resolution regardless of what you're watching.
A:AnswerHello Wendy, Yes you sure can! Simply connect it using the provided cables from DirecTV. You can also download the DirecTV app off of the Roku App Store.
