A: Yes you can and yes I would. Great quality
Q: Is this TV compatible with Direct TV without getting a tech from Direct TV to hook it up?
A: Hi there! Yes, you can use the DIRECTV Stream app on a Pioneer Roku TV, which allows you to stream content without needing a separate satellite receiver. - Shiela | Pioneer Support
Q: Does this TV have a smart remote controller where you can point it anywhere and it'll work?
A: Hello Leo! Thank you for your question. No, this TV comes with a standard Roku IR remote, which does require line‑of‑sight to the TV and cannot be pointed anywhere. It is not the “point‑anywhere” or voice‑enabled style remote. Pramodh | Pioneer
Q: Does this TV have the Next Gen Tuner ?
A: Hi, thank you for reaching out. The Pioneer 70" Class LED 4K UHD Smart Roku TV includes ATSC, NTSC, and Clear QAM tuners, but it does not support the NextGen TV tuner (ATSC 3.0). If you have any questions or need further assistance, please don't hesitate to reach out.888‑287‑7658 or [email protected] Mueez | Pioneer support
A: Hi, The Pioneer 70" Class LED 4K UHD Smart Roku TV does not support dual audio output simultaneously. When you use the optical audio output for your hearing aid adapter, the TV will typically disable the internal speakers or other audio outputs. If you need both your hearing aid adapter and wireless speakers to work at the same time, you may need an external audio splitter or sound system that can route audio to multiple devices. - -Ed | Pioneer Support | https://www.bestbuy.com/site/brands/best-buy-brands/pcmcat1596746025285.c?id=pcmcat1596746025285
Q: Can headphones connect by Bluetooth to this TV?
A: I downloaded the Roku app and can wirelessly connect to the TV with my headphones
Q: how big dose the stand have to be
A: Hello Ken. Thank you for your inquiry! The Pioneer - 70" Class LED 4K UHD Smart Roku TV (Model: PN70-R851-26U) requires a TV stand that can accommodate the distance between its legs, which is approximately 58.25 inches wide. This means your stand should be at least 59 inches wide to safely support the TV without overhang or instability. Keith | Pioneer Support

Incredible deal
This TV is perfect and an incredible deal. The picture quality is crisp and bright. The sound is more than enough and the size (70”) fits perfect on our mantle. That fact that it is a Roku tv allowed me to setup all of our streaming apps in minutes. I am extremely happy with my purchase.

- Rated 5 out of 5 stars
Unbeatable picture quality and unbeatable value
Excellent smart television with the trusted and easy to navigate Roku operating menu. Before purchasing, I looked in store at all the other larger screen (70 inches and above) and there was no comparisons between screen resolution, color science, and the finish of the Pioneer HDR ROKU smart television! It was not only one of the best values in the store, but also an excellent value
