Budget flat-panel TVs are mostly LED-LCD, OLED, or QLED today. Prioritize 4K/HDR support, appropriate inputs (HDMI 2.1/eARC), brightness for your room, and a reliable smart platform. Test no-name models before buying and check return and warranty terms.
DVI and HDMI use compatible digital video signaling, so passive DVI↔HDMI cables pass video reliably. HDMI adds audio and modern AV features (ARC/eARC, CEC, higher bandwidths) that DVI lacks. Use passive adapters for video-only needs; use active converters or HDMI gear when you need audio or advanced HDMI features.
Use modern Bluetooth or RF TV headphones (or a transmitter) to listen privately without disturbing others. Check your TV's outputs, prefer low-latency options for lip-sync, and pair or connect a transmitter to get clear, private sound.
