A: Hello there. Thank you for sharing your inquiry with us. We understand your question about using your iPhone with casting and the difference between Chromecast and Google Cast for your 55UA7700PUB TV. To directly answer your questions: Casting with iPhone: Your LG 55UA7700PUB TV supports Apple AirPlay 2, which is the primary and easiest way to share content from an iPhone or other Apple devices to your TV. Since your TV also has Google Cast built-in, you can use this feature to cast from most Cast-enabled apps on your iPhone (like Netflix, YouTube, or Spotify) by tapping the Cast icon within the app. Chromecast vs. Google Cast: Google Cast is the name of the software protocol (the technology) that enables one device (like your phone) to send content to a receiver device (like your LG TV). Chromecast is the name of the physical streaming hardware device (the dongle) made by Google. Since your TV has Google Cast built-in, it means the TV can act as the receiver without needing to plug in the separate Chromecast hardware dongle. https://www.bestbuy.com/product/lg-55-class-ua77-series-led-ai-4k-uhd-smart-webos-tv-2025/JJ8VPZT6FH If you have any further questions about its features or need a step-by-step guide on how to use AirPlay 2, please send us a private message on Social Media @LGUSSupport, and our team will be more than happy to assist you. —Renzo
A: The LG 55” Class UT75 Series LED 4K UHD Smart webOS TV (2024), Model # 55UT7570PUB, has preinstalled apps, and if you are streaming from the preinstalled apps on the TV or compatible apps that you download and install on the TV, the TV supports virtual fast forward, rewind and pause functions, which are also supported when streaming from apps on your cable set-top box. These virtual functionalities are compatible with various streaming services. However, the specific features may vary depending on the apps used. We are unclear about what a "weird guide" is, but the TV has a 'Viewing Guide' that allows you to view programs and the schedule of each program, when you select Live TV with the input button. You can view information on the channel and broadcaster. Program information is not displayed for channels with no provided broadcast information. After connecting the Set-Top Box, you can view programs and the schedule of the Set-Top Box. Your DVR has a TV guide feature. Many DVRs, especially those that support over-the-air (OTA) channels, come with a built-in channel guide that allows you to view and record shows, which is different from the TV's TV guide, but you may still be able to see your DVR's built-in TV guide feature on the TV...^Ivan.
