4K playback requires a stable stream of video data, but the actual bitrate varies with the platform, encoding, scene complexity and device. This page does not set a universal bandwidth threshold or treat a route name as a picture-quality guarantee. Check the target platform’s requirements for your device, then see whether playback reaches the desired quality and stays stable.
Dolby Vision is an HDR format, so bandwidth alone cannot determine whether it will work. Your plan, whether the title is available in that format, the app or browser, display and external playback chain can all affect the result. A format badge on a title page does not mean your device is currently playing it in that format; check the playback information in the app or your device status.
If a video starts but buffers often or repeatedly drops in quality, first pause large file transfers on the same network, then check your local Wi-Fi signal and route. If possible, compare with a wired connection or a more stable local network. If your local network is unchanged and a route switch clearly improves playback, there’s more reason to investigate the route.
HD streaming also uses plan data. Actual usage depends on the platform’s adaptive quality settings and what you watch. VPNMC monthly plans are ¥9.9/month for 60GB, ¥18/month for 250GB and ¥28/month for 500GB. Data resets monthly on the activation date. Choose a capacity based on your viewing habits; a data allowance does not translate to a fixed number of viewing hours.
