How Many Watts Does a 32 Inch TV Use? | Find Out the Required Wattage for Different Brands

A 32-inch (LCD/LED/OLED) TV uses power in the range of 50-85 watts. But the number may vary depending on different factors. Such as resolution, refresh rate, and brand.

Old 32-inch CRT TVs used to have a rating of 150-200 watts and plasma TVs around 160 watts. Now modern 32-inch LCD TVs consume 50-85 watts and LED TVs around only 50 watts. OLED TVs are around 55-60 watts, slightly higher than LEDs due to higher resolution and refresh rate. 

Power Consumption of a 32 Inch TV Use

The answer to this question is not straightforward, because the wattage rating of TV varies from brand to brand, type to type, and screen size to size. The most common TV types today in the market are LCD, LED, and OLED. CRT and Plasma televisions are now obsolete due to the arrival of newer technologies with better image quality and lower energy consumption.

Understanding the Wattage Rating of TV

The wattage rating of a TV is the energy consumed by the television per unit of time. It’s crucial to know this rating for calculating the cost of operation of the television. 

Television may have different wattage ratings listed on its website or operating manual, such as maximum power, average power, and standby power.

• Maximum power: It is the power consumed by the television when the brightness and sound level are set to maximum. 
• Average power: It is the practical power usage of television, in which the television usually operates. 
• Standby power: The power a television uses when it is plugged in but is not turned on is standby power.

How to Know the Power Rating of a TV?

The power rating of a TV may be found from its specifications sheet or measured manually using common tools.

By inspection

• Check the box the TV came in, the average power rating is generally written on it. 
• The user instructions manual/the specifications sheet also contains the power rating. 
• If the box or manual is not available, search the model number of the TV on google, the power rating will be surely obtained from one of the search results.

By using wattmeter

This method uses a wattmeter or a multimeter to measure the watt rating of a TV.

• Connect the TV to the outlet through a wattmeter and turn it on, the wattmeter will measure and display the wattage of the TV.
• Alternatively use a multimeter to measure the current drawn by the TV and the phase voltage. Multiply the current and voltage, and the watt rating of the TV is obtained.

How to Calculate the Cost of Operation of a TV

You need to know only three things to calculate the cost of operation of your TV. The wattage rating of the TV, the total time of its operation in hours, and the cost per unit of electricity. Use the formula,

Total Cost = ((watt rating * time)/1000) * unit price of electricity

Suppose, a 32-inch Samsung LED TV (35 watts) operates 300 hours a month, and the price of electricity in the USA is 10.42 cents per 1kWh, its operating cost per month will be ((35*300)/1000) *10.42 = 109.41 cents or 1 dollar 94 cents.

How many watts does a 32-inch LG LED TV use?

A 32-inch LG LED TV has an average wattage rating of 41watts and a standby power rating of only 0.3 watts. These numbers may vary because LG has several models of 32-inch LED TV available in the market with slightly different power ratings.

How Many Watts does a 4K TV Use

4K TVs use the OLED technology so their wattage rating is similar to an OLED TV. For a 32-inch 4K screen, it’s around 55-60 watts, slightly higher than LED screens of the same size.

Frequently Asked Questions

Do LED TVs require less electricity than LCDs?

Yes, LED TVs are much more energy-efficient than LCD TVs. They are the most energy-efficient TV available on the market. They require around 40% less electricity than LCD TVs and only a fraction of the electricity usage of older CRT or Plasma screens.

Conclusion

The wattage of a 32-inch television is dependent on mainly the type and brand of TV. Only an approximate idea can be obtained from the discussion about how many watts a 32-inch TV use. For exact data, the wattage rating of television must be obtained from the manufacturer or measured personally using a wattmeter.
