The 50P735 is a 50 inch 4K TV from TCL, launched in the year 2022. It comes with a 10-bit VA panel. It can achieve a maximum resolution of 3840 x 2160 @ 60 Hz with a pixel density of 89 ppi.
Picture Quality
After screen size and resolution, the next most important spec to look for in a display is its Color Reproduction, which is defined by its color gamut specification.
Speaking of which, this TV comes with a DCI P3 gamut coverage of 75%. Incase you're wondering, this is equivalent to 102.27% sRGB coverage. Meaning, the color quality on this TV should be excellent! Your content viewing experience would be world class on this TV.
Understanding Color Gamut
Color gamut specification of a display is a measure of the range of colors that it can display.
A panel with poor color accuracy will produce undersaturated colors that will spoil your immersive experience.
It is specified in different units - sRGB(most popular), NTSC 1953, DCI P3 etc. It is upto the manufacturer which one they choose.
For example, the color gamut of this TV is specified in terms of DCI P3.
But you don't need to worry about that, here is a chart that will help you choosing a TV with good color accuracy.
After color gamut, you should look at the static contrast specification as it influences the picture quality substantially.
What is Static Contrast ratio ?
Static contrast ratio of a TV corresponds to its Black levels. A TV with low static contrast ratio (<1000:1) will not produce deep blacks. Also, such TVs often suffer from backlight bleeds such as this:

Needless to say, this will impact your experience, especially in a dark room.
Other than black levels, a TV with high constrast ratio allows you to see more details. So, resolution and static contrast ratio go hand in hand in a sense.
If given a choice, I will prefer a FHD TV with high contrast ratio over a 4K TV with low contrast ratio.
This TV features a static contrast ratio of 5000 : 1., well enough to produce deep blacks. The panel comes with local dimming backlight which is a plus.
HDR is also supported on this TV in form of HDR10, HLG (Hybrid Log Gamma) and Dolby Vision.
Coming to brightness, the peak brightness the TV can produce is 270 nits. The backlight of this TV is powered by Direct LED technology.
Gaming Performance
If you are going to use a TV other than watching videos — say as a PC monitor or for gaming purposes, you would want to get a TV that features the lowest input lag. For gaming, both the input lag and response time impacts the performance.
The input lag on the TCL 50P735 is 15 ms and its minimum response time is 8 ms. It is good enough for both casual and competitive/FPS games.
What is Input Lag and Why it matters ?
This lag is the latency at which your key-presses or mouse movements changes the content of your TV. For casual Non-FPS games, input lag doesn't matter much.
Although for better experience, get a TV that features an input lag and response time of less than 20ms.
Ergonomics and Dimensions
Speaking of ergonomics — If you plan to wall mount the TV, you can make use of the VESA mount provided with this TV, which by the way has an interface size of 200 x 300 mm. However, there is no Swivel, Tilt or Pivot feature support on this TV.
Vertically, the TV measures 50 inches and horizontally 43.78 inches. It is 2 inches thick.
Overall the TV weighs 11.0 KGs (including stand). Without stand, it weighs 10.7 Kgs. So plan your space accordingly.
Hardware and Audio
The chipset of TCL 50P735 is powered by a Quad Core CPU. However, TCL didn't provide any specification on the RAM on the TV's specsheet.
For display connectivity, there are three HDMI 2.0 (4:2:2) ports and one AV Composite In 3.5 mm jack port on this TV.
For connecting USB devices, it includes 1x USB 2.0 and 1x USB 3.0. Other connectivity ports include — 1x Satellite In (F-type), 1x Antenna (RF), 1x CI+ 1.4 and 1x Ethernet RJ45.
Wireless connectivity options on this TV include Wi-Fi (5Ghz + 2.5Ghz), Wifi-Direct, Bluetooth and DLNA.
Speaking of speakers, TCL has provided 2 x 10W built-in speakers on the 50P735.
Now, coming to power usage, on average, it consumes around 57W. On standby, it takes 0.54 W.
