– Philips P5 Perfect Picture. The Philips P5 Perfect Picture Processor is used in Philips OLED TVs. The processing power of the processor is enough to reproduce the 4K image. In older models, an extended dynamic range of HDR colours is found. TVs with the Philips P5 Perfect Picture processor cover several cost categories at once, the low-cost segment and the average price range. A high-quality picture is displayed on the screen of such models, but, usually, it falls short of the reference Ultra 4K HDR, since this requires a more professional matrix. The P5 Perfect Picture processor is the first Philips CPU to use artificial intelligence. Philips P5 Perfect Picture supports technologies such as Dolby Vision, HDR10+, Perfect Natural Motion and Micro Dimming Pro.

– Philips P5 Pro Perfect Picture. The Philips P5 Pro Perfect Picture Processor is used in Philips TVs with enhanced OLED. Models with this processor are capable of displaying an image in Ultra 4K HDR resolution. Usually, it is found in advanced class TVs. Philips P5 Pro Perfect Picture processor TVs use a machine intelligence neural network interface. Google Assistant and Amazon Alexa voice assistants are supported. The processor uses the following image and sound technologies: Dolby Vision, Dolby Atmos, HDR10+, Micro Dimming Perfect and Wide Color Gamut.

The response time can be described as the maximum time required for each pixel of the screen to change brightness, in other words, the longest time from the receipt of a control signal to the pixel until it switches to the specified mode. The actual switching time may be less — if the brightness changes slightly, it can be calculated in microseconds. However, it is the longest time that matters — it describes the guaranteed response speed of each pixel.

First of all, the frame rate is directly related to the response time (see the relevant paragraph): the lower the response time, the higher the frame rate can be provided on this sensor. However, the actual frame rate may be less than the theoretical maximum, it all depends on the TV. Also note that the overall image quality in dynamic scenes depends primarily on the frame rate. Therefore, we can say that the response time is an auxiliary parameter: the average user rarely needs this data, and in the specifications they are given mainly for advertising purposes.

TV support for one or another brightness / contrast enhancement technology.

Usually, in this case, software image processing is implied, in such a way as to improve brightness and/or contrast (if necessary). Specific processing methods may be different — in particular, in some cases we are actually talking about turning standard content into HDR (see above), and some manufacturers do not specify technical details at all. The effectiveness of different technologies can also be different, and besides, it is highly dependent on the specific content: in some cases, the improvement will be obvious, in others it may be almost imperceptible. Also note that this feature is not always useful, so in most models it is turned off.

The TV's support of one or the other colour enhancement technology.

Such technologies usually involve image processing in software to provide brighter and/or more accurate colours. Specific processing methods may be different, some manufacturers do not specify technical details at all, limiting themselves to advertising statements. The effect of using such technologies can also vary: in some cases it is clearly visible, in others it is almost absent, depending on the features of the picture. It is also worth saying that this feature, usually, needs to be turned on manually in the TV menu (accordingly, it can be turned off if desired).

— VRR. VRR (Variable Refresh Rate) adaptive frame rate synchronization technology allows you to adjust the refresh rate of the image on the TV screen in real time in accordance with the frame rate output by the game console or connected computer. The function ensures smooth rendering of dynamic scenes, eliminates frame breaks, and guarantees comfortable and stable gameplay. Realizable technology with standard HDMI v 2.1.

— ALLM. Automatic low latency mode for games (Auto Low Latency Mode). The TV switches to game mode when it detects a game console connection. Reducing the output delay on the TV panel screen is provided by suspending part of the image processing functions. The ALLM mode can also be useful for karaoke and video calls.

eARC. HDMI v 2.1 has an enhanced eARC (enhanced Audio Return Channel). The technology allows you to send higher quality audio from your TV to your soundbar or AV receiver. It claims to support the latest high bit rate audio formats up to 192 kHz, uncompressed 5.1 and 7.1, and 32-channel uncompressed audio. eARC also supports Dolby TrueHD, DTS-HD Master Audio, DTS:X, Dolby Atmos.

— CEC. The CEC (Consumer Electronics Control) system is designed for remote control of equipment connected to the TV using a single remote control. The devices are connected to the TV panel using an HDMI cable.

The electrical power normally consumed by the TV. This parameter strongly depends on the screen size and sound power (see above), however, it can be determined by other parameters — primarily additional features and technologies implemented in the design. It is worth noting that most modern LCD TVs are quite economical, and most often this parameter does not play a significant role — in most cases, power consumption is about several tens of watts. And even large models with a diagonal of 70 – 90" consume about 200 – 300 W — this can be compared with the system unit of a low-power desktop PC.

The energy efficiency class characterizes how efficiently the TV consumes electricity. Initially, the classes were denoted by simple Latin letters — A (the most efficient), B, C. However, later improved classes “A+ ”, “A++”, etc. appeared (the more "pluses", the more efficient the device).

The energy class will generally affect the price accordingly, but this difference will eventually pay off with lower electricity bills.
