What to know before buying

Listing details to confirm

Listing details are inconsistent about dimensions: one gives 29D x 123W x 99.6H centimetres, while another gives 29 x 123 x 99.6 cm; 19.05 kg. Confirm the cabinet measurements and weight before planning installation. The 144Hz refresh rate, QD-Mini LED description and 4K resolution are listing claims, not independently verified here. The title and feature copy claim a flush wall mount is included, but the listed contents name only a stand, so confirm the selected package if wall mounting.
