Overview
55A300-Pro from TCL pairs a 54.5-inch 4K screen with VA display hardware and a Edge LED backlight. Google TV (Android 12) provides the app interface, while AIPQ Pro handles picture processing and navigation. Quantum Dot colour strengthens the specification beyond a basic LED LCD, although no measured gamut figure is published. HDR support includes Dolby Vision IQ, HDR10+, HLG, but neither typical nor peak brightness is published, so visible HDR impact remains uncertain. Gaming reaches 48 Hz - 144 Hz with AMD FreeSync Premium, making the TV suitable for current consoles and many gaming PCs. Buy it if you want a design-led 54.5-inch Google TV with broad HDR support and high-refresh gaming; skip it if you need published brightness figures before judging HDR strength.

HDR & Brightness Reality
TCL 55A300 Pro accepts Dolby Vision IQ, HDR10+, HLG, giving it broad compatibility with current streaming, disc and broadcast sources. The Edge LED backlight is conventional LCD hardware, so HDR impact depends heavily on brightness and contrast rather than format logos. Neither typical nor peak brightness is published, so the table confirms compatibility more clearly than visible HDR intensity. No DCI-P3 measurement is supplied, so colour-volume claims should remain conservative.
