Why does my 4K display flicker with some USB-C hubs?

Display flickering usually indicates the hub doesn't support HDMI 2.0 properly, or there's a bandwidth conflict between the display signal and USB data on the same cable. Fix: ensure you're using a 4K@60Hz capable hub (not 4K@30Hz), check that your USB-C cable is rated for data + video, and try a different USB-C port on your laptop if available. Thunderbolt 4 hubs have the highest bandwidth and typically solve flickering issues.

Can USB-C hubs damage my laptop?

Quality hubs from reputable brands (Anker, Belkin, UGREEN) with proper power protection circuitry are safe. Cheap, unbranded hubs from unknown manufacturers risk sending incorrect voltage through the USB-C port. Stick to brands with extensive Amazon reviews and avoid hubs under $10 with no brand name. The risk is low but real with counterfeit or extremely cheap hubs.

Do USB-C hubs work with iPhones and iPads?

Yes, with caveats. USB-C hubs work with iPad Pro and iPad Air (which have USB-C ports). For iPhone 15 and 16 series (USB-C), hub functionality depends on the iPhone's USB-C implementation — most basic data transfer and charging functions work, but display output requires certified cables and adapters. Pre-iPhone 15 models (Lightning) don't work with USB-C hubs directly.
