Can the wall-mounted advertising machine display screen be used as a TV set (B)

1. The brightness is dazzling and the color is distorted:
In order to resist ambient light (especially bright lights in shopping malls), the brightness of advertising machines is often as high as 500 nits or even more than 1000 nits, which is several times that of ordinary home TVs (about 250-400 nits). In a relatively dim living room environment, this brightness is like looking directly at a small lamp, which can easily lead to visual fatigue.
At the same time, its color adjustment tends to be bright and eye-catching, rather than the true and natural restoration pursued by TV, which makes it extremely uncomfortable to watch for a long time.

2. The hardware configuration is "partial" and it is not enough:

The core task of the internal chip of the advertising machine display screen is to stably decode the fixed content that is played circularly. In the face of complex real-time decoding of TV signals and high-definition network video streams, or running apps and playing games, its processing capacity is stretched. Consequences?

Stuck, dropped frames and slow response are normal, far from the smooth and silky operation experience of TV. The remote control is usually very simple, only the basic up and down keys, adjusting the volume may make you feel sore.

3. The content input "channel" is narrow:

The interface design of most advertising machine display screens is extremely simple, and there may be only one USB port for importing advertising films, lacking the key HDMI interface. This means that you can't connect home entertainment core devices such as set-top boxes, game consoles and Blu-ray players, and the TV function is useless.

4. Complex operation and complicated management:

Advertising machine display screens usually rely on special software to publish and manage content through USB flash drive, network or specific system, and the operation logic is very different from that of user-friendly smart TV system.

For ordinary home users, if they want to change channels or broadcast a TV series, the process may be as complicated as a small IT operation and maintenance.

Really want to use it?

See these three conditions first.

If you still want to try, be sure to confirm the target advertising machine display screen and meet the following three conditions: having an HDMI input interface (which is the basis for connecting set-top boxes and other devices), supporting multi-level brightness adjustment (at least close to the comfort range of TV), equipped with a relatively normal remote control or supporting external connection. Even so, there is still a huge gap between its picture comfort, smooth operation and sound effect and the real TV.

Conclusion: There is specialization in the technical field.

Although the wall-mounted advertising machine display screen and smart TV share the carrier of "screen", the original design intention, core performance and optimization direction are completely different.

The strong environmental adaptability and cyclic playback stability of the advertising machine can't make up for its fundamental defects in image quality comfort, interface compatibility, operation convenience and comprehensive audio-visual experience as a home display device.

If you pursue good family audio-visual enjoyment, a professional TV set is still an irreplaceable choice-it is a wise choice to let the advertising machine display advertisements with peace of mind and let the TV set focus on pleasing the eyes and perform their duties. It is not a long-term solution to sacrifice daily comfort to save short-term profits.
