It's more than about the dis­play, res­o­lu­tion and size

Like with air con­di­tion­ers (fea­tured in the Au­gust is­sue), choos­ing a tele­vi­sion is not an easy task. There is a huge ar­ray of brands/mod­els out there, claim­ing dif­fer­ent fea­tures and of­fer­ing var­ied panel sizes within the same price range. There are LCD TVs, LED TVs and OLED TVs to look at. So, it all starts from what type of dis­play technology you want. Then, most of us tend to stick to known, lead­ing brands. But these may not be the best choice al­ways. There are var­i­ous fac­tors to con­sider, other than the brand name. For example, does the brand have a net­work of ser­vice cen­tres in your area? Is some in­stal­la­tion in­cluded in the price, and what kind of war­ranty does it come with? The fol­low­ing com­pi­la­tion will help you sort out the cri­te­ria you may ap­ply when choos­ing your new TV and also does a quick com­par­i­son of brands on some help­ful pa­ram­e­ters. There are lots of ab­bre­vi­ated tech-spe­cific terms nowa­days—for example, HDMI, SPDIF, DLNA—but let that not over­whelm you, be­cause a lit­tle bit of ex­tra ef­fort to study your re­quire­ments will make all the dif­fer­ence to your TV ex­pe­ri­ence.

By Dis­play Type

LCd: Liq­uid crys­tal dis­plays are pretty com­mon to find, and may be the cheaper op­tion. They are en­ergy-ef­fi­cient and usu­ally have good colour.

Led: TVs branded as LED are ac­tu­ally LCD TVs that use LEDs as a back­light for the liq­uid crys­tals in the dis­play. If a TV has ‘lo­cal dim­ming’, it will have an ad­van­tage when it comes to con­trast ra­tio, which is a plus. On top of that, LED TVs are less pow­er­hun­gry than stan­dard LCDs and plasma.

OLed: Or­ganic light-emit­ting diode (OLED) TVs ac­tu­ally are dif­fer­ent from LCD TVs. OLED TVs use coloured LED lights to cre­ate the im­age, so they save on power, though not al­ways as much as LED TVs. They do man­age to cre­ate a high-qual­ity im­age, and a bright one at that, so they may be best for those plan­ning on watch­ing TV a lot dur­ing brighter hours, when glare could oth­er­wise be a prob­lem. They also have high con­trast ra­tios, as black pix­els will ac­tu­ally be emit­ting no light, which cre­ates great cin­e­matic vi­su­als. OLED screens are costly to make, so you’ll have to pay more. They also suf­fer from some of the view­ing-an­gle prob­lems.

By Res­o­lu­tion

HD-ready, full HD, or 4K? The higher the res­o­lu­tion, the bet­ter the im­age qual­ity. HD-ready offers 1,366 x 768 pix­els res­o­lu­tion, full HD 1,920 x 1,080 pix­els, and 4K 3,840 x 2,160 pix­els. We rec­om­mend that if you have the bud­get, get a 4K TV. If not, then go for a full HD screen. HD-ready TVs are cheaper and while they are good enough for watch­ing SD (stan­dard def­i­ni­tion) con­tent, you can no­tice the marked dif­fer­ences in sharp­ness and clar­ity com­pared to a full HD TV.

By Size

The com­mon TV panel sizes avail­able to­day are 32, 40, 42, 46/49 and 55 inch. To de­ter­mine the ideal screen size for best view­ing ex­pe­ri­ence, mea­sure the dis­tance be­tween where the TV will be placed and your bed/couch/chair.

Per­haps the most im­por­tant choice you are going to make with a new TV is the size of the screen. You could con­sider an even big­ger set for spa­cious fam­ily rooms, or if you will be sit­ting very far from the TV. Con­sider how many peo­ple in your fam­ily typ­i­cally watch at once and where you are going to put your new set. Then pick the largest screen size that will fit com­fort­ably into that space—and your bud­get.

Other Cri­te­ria a) Do You Want a Smart TV?

Smart TVs have been around for a while now and you can eas­ily get one for less than Rs 50,000. Smart TV comes pre­loaded with an op­er­at­ing sys­tem (OS) – An­droid, Google TV, Tizen, etc. – that func­tions sim­i­lar to a smart­phone OS. You can con­nect to the in­ter­net to view con­tent, in­stall ad­di­tional apps and even games. Smart TV de­liv­ers a much bet­ter over­all user ex­pe­ri­ence. How­ever, keep in mind that smart TV is ex­pen­sive com­pared to the nor­mal TV. You can get a 42-inch nor­mal TV at the price of a 32-inch smart TV.

b) Do you have HDMI ports?

Most peo­ple tend to for­get check­ing the num­ber of de­vices that can be con­nected to their tele­vi­sion. The ma­jor­ity of the de­vices to­day use an HDMI (high­def­i­ni­tion mul­ti­me­dia in­ter­face) port for con­nect­ing to the TV for best qual­ity video and au­dio out­put. How­ever, they can also be con­nected via a com­pos­ite/ com­po­nent port, if re­quired. If you plan to pri­mar­ily con­nect high-def­i­ni­tion sources, look for a TV with at least four HDMI ports – this will be help­ful as you won’t have to change wires when switch­ing de­vices.

c) Check if the TV has op­ti­cal or SPDIF/coax­ial au­dio out port

Most slim TVs come with dual 10 watt (RMS) speak­ers that tend to blare on vol­umes above 70 per cent. If you want a qual­ity au­dio ex­pe­ri­ence, we rec­om­mend you in­vest in a home theatre or a sep­a­rate speaker sys­tem. Check if the TV has op­ti­cal or SPDIF/coax­ial au­dio out port – it’s ideal for mul­ti­chan­nel au­dio out­put. If the TV with these ports is not in your bud­get, then you can use the more com­monly avail­able 3.5 mm (head­phone) au­dio jack that most TVs come with.

d) Check if the TV has built-in wi-fi or sup­ports ex­ter­nal wi-fi USB don­gles

In­ter­net con­nec­tiv­ity on a TV has mul­ti­ple ben­e­fits. You can ac­cess on-de­mand mul­ti­me­dia con­tent, keep a tab on your so­cial net­work, and in some cases even make video calls. If your TV has built-in-wi-fi or sup­ports ex­ter­nal wi-fi USB don­gles, you will be able to con­nect your home wi-fi net­work and stream au­dio/video con­tent on your TV. Most smart TVs come with DLNA or Mira­cast sup­port, which al­lows you to wire­lessly stream con­tent from your smart­phone/tablet di­rectly to the TV.
