1 - Install IPTV apps Yes, you can download and install IPTV apps on the device. The TV runs on Philips' Titan OS with access to an app tab where you can download popular apps like Smart IPTV or Zattoo directly
2 - Compatibility with Nintendo Switch In principle, the TV is compatible with the Nintendo Switch via HDMI - this is standard for smart TVs like this one. However, users in forums report occasional problems such as picture dropouts or flickering on Philips models, especially when the Switch is operated in docked mode. If absolutely stable operation is important to you, a firmware update could help - or, if in doubt, a different model.
3 - Returns and fees This depends on the retailer. Digitec/Galaxus offer a 30-day return policy with free returns, provided the original packaging and all parts are present - no fees apply
