From its sleek design to its advanced miniLED technology, we will explore why the TCL C845 is a good contender in the world of smart TVs. As an upgraded version of the recently reviewed TCL 745, it offers advanced features at a slightly higher price point.
Before we proceed with the review, please note that our analysis of the TCL C845 is based on rigorous testing and real-world usage scenarios. While we did receive a review sample of the TCL C845, it was solely for testing purposes and does not influence any aspect of our forthcoming review.
Design and Build Quality
The TCL C845 greets you with a clean and streamlined design, draped in a dark grey plastic chassis. Notably, its flat center-aligned stand provides robust stability to the 65-inch behemoth, whether placed on a table or wall-mounted.
The TV’s ports are conveniently positioned to the side, ensuring accessibility even in wall-mounted configurations. It’s an ergonomic design that understands practicality.

TCL C845 Gaming Performance
To assess the TCL C845’s performance, various display parameters are measured for different content types, including SDR and HDR. Brightness, black levels, contrast ratios, and color space coverage are all taken into account.
The TV’s input lag is also measured in different modes to determine its responsiveness, especially for gaming.
|Input Lag||Movie Mode||Game Mode|
|1080p SDR||119.3 ms||15.3 ms|
|4K SDR||119.3 ms||15.2 ms|
|4K HDR||119.2 ms||15.2 ms|
Energy consumption measurements are recorded to provide insights into the TV’s power usage.
|Energy Consumption||Out-of-box (average)||Calibrated (average)|
|SDR||103 W||56 W|
|HDR||230 W||230 W|
Picture quality is a cornerstone of any TV’s appeal, and the TCL C845 excels in this area. The miniLED FALD technology enhances contrast and peak brightness in both SDR and HDR content.
