1. Television Resolution and Clarity :
 Pixels, Pixels and more Pixels. One of the key and the most important term for everything related to Picture quality is Pixels. But why should you care? Clarity, Contrast and Colour all revolves around how each pixel is being displayed on the television display. The information that is being transmitted to the television need to be realized and presented to you without any noise, whatsoever. The resolution, that is the proximity of pixels from each other attempts to partly address this. However the senses needs more illuminated , more darker, grayer and colourful pixels where applicable. All the manufacturers address or attempt to address this aspect with different technology implementation and terminology.

2. Television Contrast: 
 Brightness and darkness display capability or Dynamic range of what the Television can display is one of the contrast aspects. Let’s discuss about the human eye that has the best possible dynamic range, just accurately able to identify the differential between different black, grey and white regions. The technology has evolved from HDR or High Dynamic Range to Dolby Vision that is very high Dynamic Range. it’s important that the content that is being transmitted to the television is also HDR. Seeing is believing, make sure to check on the upscaling feature of the content to HDR that is being marketed by the manufacturers. Upscaling probably only attempts to display normal quality videos to HDR. There is usually a picture processor and an algorithm involved increasing the cost of the hardware itself.

3. Television Colour: 
 Let’s get to the bit level understanding of the digital display. You would come across terminologies like 8 bit and 10 bit colour. All colour combinations that can possibly be displayed with each pixel R (Red), G (Green) and B(Blue) is limited to the number of bits each pixel is made of. Yes, there are three different pixels the display is made of that is RGB.
 With 8 bit colour : R = 8 Bits(256 combinations), G = 8 bits & B = 8 bits, possible colour combinations is 256 x 256 x 256 = 16777216 colour combinations. With 10 bit colour, colour combinations would be 1024 x1024 x 1024 = 1073741824 colour combinations. It’s certain that a 10bit colour display would be able to reproduce better colours than a 8 bit one. Apart from this, different manufacturers use different techniques to enchance and make the colour look as real and lively as possible.

4. Television Motion Blur : 
 You may check the motion rate that is the refresh rate specification of the television. 
 50Hz — for smooth picture and general viewing.
 100Hz — for faster action. 
 200Hz — for high speed gaming.
 The processing capability on the television has increased the motion rate of the television to beyond 1000 now a days. Look at this specification based on actual usage of the television.

5. Television Sound Quality :
 This is defined by number of speakers, speakers output Power rating, additional woofers and subwoofers supplied with the television. In general, a 4.2Ch sound system would have 4 speakers with 2 woofers/subwoofers. The higher the power rating, the more the sound decibel levels the speaker can produce. Choose depending on the size of the room for placement of the television.

6. Television Connectivity :
 Check what external devices you would prefer to connect with the Television like Set-top box, DVD Player, pen drive simultaneously. Important ports to look at are HDMI with or without ARC and CEC, USB, MHL, Ethernet( LAN ), Digital Audio and headphone connector. CEC would let one TV remote, control all other devices with the same remote. With MHL, you can directly connect the TV with the MHL Capable mobile and watch HD multimedia content.
 Choose the wifi option only if you intend to browse on the TV. However, most high end televisions would have Wifi inbuilt and wifi-direct that let’s you connect other devices with the television directly. Mirroring is another option to look at, to display the mobile content on television wirelessly.

7.Options and Accessories :
 Few of the additional options and accessories that are available on high end Televisions are 
 — Camera and Mic for Video conferencing.
 — Recording option.
 — Multiview on the same screen.
 — Multiroom Link that lets you create a complete and unified audio system running throughout different rooms in your home.
