But You can only watch up to 2 simultaneous 3.0 channels (or can record 2 atsc 3.0 channels if you are using the DVR feature of the HDHomeruns) A few of the very newest (typically OLED) TV's are able to be directly compatible to play this back (the AC-4 audio which is a Dolby format that is NOT commonly supported yet) or as others are noting, you can tune to and play the 3.0 broadcasts on most of the HD Homerun apps on some (not all) devices. NVIDIA shield probably the best bet. Interestingly the Channels App downloaded with NVidia sheield or several NAS (network attached storage) devices that support that application can now record/playback the format and handle the audio as well. **Q: What is the difference between this flex model and the hdhr5-4k?** A: The FLEX 4K is a CONNECT 4K with a USB port for optionally connecting a hard drive. With no hard drive plugged in it works exactly the same as a CONNECT 4K. **Q: What codec is the content streamed in?** A: There is at least one streaming player that supports AC-4 audio, the Roku Ultra 4800. It has to be the 4800 model, as that is the only Roku that supports AC-4 audio. **Q: I have a 1 tb hdd, 3 non-smart tvs with firestick, 3 avr audio systems with hdmi, and 100+ gb/s wifi. what else do i need to make this work?** A: You need 1) an over the air (OTA) antenna, 2) an ethernet cable to connect the HDHRun to your router or ethernet switch (no WiFi), and 3) Your hard drive needs to be connected to same home network if you intend to use it to DVR OTA TV programs. Keep in mind the HDHRun is an internet dependent system. If your internet goes out, the HDHRun unit won’t work at all. I have both the Tablo dual, and an HDHR 4k flex unit. I prefer the Tablo since I can watch live and recorded TV while the internet is down (home network must be running though). You also connect your hard drive directly to the Tablo via USB, and it can use either WiFi or ethernet hardwire to connect to the app. The Tablo app you download from the app store will find and connect to it - same as the HDHR appa. I haven’t tried AirTV yet. It looks promising, and will interlace the OTA broadcast with Sling. The HDHR is a good quality device, but has several aspects I find annoying. 1) I already mentioned that it MUST be connected to the internet before the home screen will come up. 2) Hardwire ONLY connection to your home network. 3) Access to the channel scan utility is not within the app. You access the channel utility through the device’s IP address. 4) You have to pay Silicon dust a subscription ($30/yr) to use the DVR function. Tablo only requires a subscription to get a 2 week grid guide - else you only get 24 hours look ahead. Hope this helps. ## Frequently Bought Together - SiliconDust HDHomeRun Flex 4K ATSC 3.0 NextGen TV: 2/4 Tuners HDFX-4K - SiliconDust LPF-608M LTE Filter for TV Antennas USA 2020 Standard 600/608/618MHz - Antennas Direct ClearStream 2V Indoor Outdoor TV Antenna UHF VHF Multi-Directional, 60+ Mile Range, 4K 8K UHD, NEXTGEN TV – w/Reflector, 20-inch Mast --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.mx/products/311348621-silicondust-hdhomerun-flex-4k-atsc-3-0-nextgen-tv-2](https://www.desertcart.mx/products/311348621-silicondust-hdhomerun-flex-4k-atsc-3-0-nextgen-tv-2) --- *Product available on Desertcart Mexico* *Store origin: MX* *Last updated: 2026-06-01*
