Samsung QM55C 55-inch Crystal UHD Signage Display

The standard size for corporate signage installations

The QM55C is the most commonly used size in digital signage projects. The reason for its popularity is simple: 55 inches fits well on most store and office walls, is easy to install, and offers a balanced cost per square meter.

It offers approximately 80 pixels per inch at 4K resolution. Text, prices, and product images are easily readable from a viewing distance of three meters.

Spare Parts and Inventory Advantages

Being the most common size also provides advantages on the supply side. In multi-location installations, keeping spare units of the same model on hand makes it possible to replace a screen within hours rather than days in the event of a malfunction.

Display and Panel

When 4K UHD resolution is spread across a 55-inch screen, it results in approximately 80 pixels per inch. The panel is VA-type, with a contrast ratio of 4000:1, a viewing angle of 178° / 178°, and a brightness level of 500 nits. Thanks to the Tizen 7.0 operating system and 16 GB of internal memory, the screen can stream content without the need for a separate set-top box.

Power and Mounting Specifications

It operates with a maximum power consumption of 154 W and weighs 15.7 kg. The 200 x 200 mm VESA mounting pattern allows it to use the same mounting bracket as smaller models.

Chassis dimensions: 1237.9 × 708.8 × 28.5 mm; weight: 15.7 kg; VESA mounting spacing: 200 × 200 mm. Maximum power consumption is specified as 154 W (max.). Product code: LH55QMCEBGCXTK.
