Some TV upgrades are only noticeable when you place a new model next to its predecessor, while others become apparent the moment you turn on the screen. The TCL Q7D RGB Mini LED, QM7L in the USA equivalent, in its 75 inch configuration, falls somewhere between those two categories, delivering a noticeably different picture from the C7L I reviewed previously, even though much of the underlying hardware and smart TV experience remains unchanged.<\/p>\n\n\n\n
After testing the C7L, which uses TCL\u2019s Super Quantum Dot Mini LED technology, I replaced it with the Q7D RGB on the same day and under the same viewing conditions. Because the new TV occupied exactly the same position as the previous model, I could compare the two directly, without relying on long term memory or footage captured from different screens under different conditions.<\/p>\n\n\n\n
The result was an interesting demonstration of how much the underlying display technology can influence the viewing experience, even when the rest of the television remains largely familiar. Before getting to the final verdict, however, it is worth understanding what makes the Q7D RGB different, where its advantages become apparent, and where the newer model does not necessarily come out ahead.<\/p>\n\n\n\n
The TCL Q7D RGB takes a different approach to backlighting than the C7L I reviewed recently, which uses a conventional Quantum Dot Mini LED architecture. The goal of RGB Mini LED is to expand the display\u2019s ability to reproduce rich, vivid colors while maintaining high brightness, although the practical results depend on more than the backlighting technology alone.<\/p>\n\n\n\n
