The QE55Q65B is a 55 inch 4K TV from Samsung, launched in the year 2022. It features a 10-bit VA panel.
The maximum resolution it can display is 3840 x 2160 with a refresh rate of 60 Hz and a pixel density of 80 ppi.
After screen size and resolution, the very next specification of a display that impacts picture quality is its Color Gamut.
The Samsung QE55Q65B is rated with a 100% DCI P3 color gamut coverage, which is equivalent to 136.36% sRGB coverage. The color accuracy on this TV will be Lifelike!
What is Color gamut ?
Color gamut specification of a TV is the measurement of the range of colors that it can show.
A TV with poor color reproduction will produce undersaturated/washed out colors that will spoil your immersive experience.
It is specified in different units - sRGB(most popular), NTSC 1953, DCI P3 etc.
As for this TV its color gamut is specified in DCI P3.
But don't worry, here is a chart that you can use to choose a TV with good color accuracy.
After color gamut, next in the list of important specifications that will impact your experience is Static Contrast.
Understanding the static contrast ratio of a TV
There are two types of contrast specifications for a TV. Static and Dynamic. We are interested in static contrast ratio as dynamic doesn't matter much.
Static contrast tells the intensity of black levels. That is, a TV with static contrast ratio < 1000:1 will produce black images something like this:
Apart from that, such TVs are also prone backlight bleeds that will affect your experience — as shown below.The image is an example of another display, it is not this one
Also, 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 comes with a static contrast ratio of 8000:1., enough to achieve deep blacks. For the record, it also comes with local dimming technology which is a plus.
HDR10, HLG (Hybrid Log Gamma), HDR10+, HDR10+ Adaptive and Quantum HDR are also supported on this TV, so that's a plus.
As for brightness, the peak luminance it can produce is 250 nits. The backlight used on the panel is Edge LED.
If you are going to use a TV other than watching videos — say as a PC monitor or for gaming purposes, you should take a TV with lowest input lag. For gaming however, both the input lag and response time impacts the performance.
Unfortunately, we cannot find the input lag specification for this unit. Now, since this is not a cheap TV from Samsung, we can expect an input lag of less than 20ms.
Understanding Input lag and response time
This lag is the latency at which key-presses or mouse movements changes the content of the screen. Though, this won't matter much if you aren't into competitive/FPS games like call of duty.
But ideally, look for a TV that features an input lag and response time of less than 20ms.
Dimensions and Ergonomics
Vertically, the TV measures 55 inches and horizontally 48.54 inches.
Coming to thickness, it is 1 inches thick. Overall this TV weighs 16.9 kilograms (including stand). Without stand, it weighs 16.1 KGs.
Coming to ergonomics — a VESA mount with interface size of 200 x 200 mm is provided for wall-mounting. Swivel, Tilt or Pivot features are not supported on this unit.
Hardware and Audio
The core of this TV is powered by 4-Core CPU. However, we could'nt find any information on the available RAM on the TV's specsheet.
The UI on this TV is powered by Tizen 6.5 Operating System.
For display connectivity, Samsung has provided three HDMI 2.0 ports on this TV.
To connect USB devices, you will have two USB 2.0 ports. Other connectivity ports include — 1x Satellite In (F-type female), 1x Antenna (RF) (female), 1x CI+ 1.4 and 1x Ethernet RJ45.
For connecting to this TV wirelessly, the manufacturer has provided Wi-Fi (5Ghz + 2.5Ghz), Wifi-Direct, Bluetooth and DLNA.
The Audio unit of this TV is powered by 2 x 10W built-in speakers.
Now, coming to power usage, on average, it uses about 77 watts. On standby, it takes 0.5 watts.
For powering this unit, you'll require an 100 V - 120 V/50 Hz - 60 Hz outlet.
