TV Wattage - 2023's Most Efficient TVs Revealed [With Data] (2024)

FAQs

How many watts is good for TV? ›

As expected, the average TV wattage consumption increases with TV size and screen resolution. On average, a 55 inch TV uses 77 watts while on and 1.4 watts on standby. On average, 4K (2160p) TVs use 80 watts while on and 0.6 watts on standby.

Modern TVs have been designed with energy efficiency in mind. Older TVs will consume the most, whereas modern LCD and LED TVs are the most efficient. The newer the device, the better the efficiency. Look for the Energy Star rating to determine which TVs will save you the most money.

LG, Samsung, and Sony OLED TVs are equipped with software-based measures to prevent burn-in.

As you're now very much aware, OLED panels don't require a super-bright backlight. Those backlights consume a fair amount of power, which means OLED TVs are inherently more energy-efficient. They also emit less heat than QLED TVs.

The table shows that the average wattage of a 65-inch TV is 148 watts.

How Much Power Does Your TV Consume? On average, a TV consumes 108 kilowatts of energy in a year when smart wake features are disabled. That said, this number increases to 191 kilowatts when smart features are enabled—increasing power consumption by 76.8 percent.

2. Screen Size. Even if you choose an LCD or OLED TV, the power consumption can be higher for large screen sizes. If you see the example of the latest LG C2 OLED TV, the 77-inch variant draws about 160 watts while the 65-inch variant draws only 115 watts.

According to recent studies, 4K TVs use on average 30 percent more power than 720 or 1080 HD TVs. Factor this startling figure against the predicted number of 4K TVs finding their way into US homes, and you could be looking at a combined increase in residential energy usage of more than a billion dollars.

Television. If you have a modern LED-lit television, you'll use far less electricity than you would using an older counterpart. But even when it's turned off, modern TVs continue to consume electricity. Make sure to unplug them or get a surge protector to block electricity from flowing.

How many watts is a 55 inch Samsung TV? ›

If there's one thing you can be sure of it's that, much of the time, you're paying more for a TV because it has better specs, more features, or because it simply performs better: higher brightness, more color, better HDR, or smoother motion.

Turning off your appliances at the wall won't magically cut your power bill in half, but it can help you further conserve energy and save on electricity.

It Saves Electricity – Small Amount

Turning a TV off at night completely and removing from standby will save electricity and will save you a small amount of money.

CON: Unreliable Performance

Like any computer, a smart TV is prone to crashing or malfunctioning. As mentioned before, if your internet is buggy, your image quality will suffer, and might even experience choppy streaming. And if your internet is slow, then sometimes your TV slows down too.

LEDs tend to be better because the light-emitting diodes create clearer images [1]. LED comes in two parts for Samsung TVs: OLED and QLED. OLED TVs have an excellent lifespan and offer a better colorful display than QLED. According to our TV professionals, most of these TVs last for between five to seven years.

Screen type – organic light-emitting diode (OLED), light-emitting diode (LED) and liquid crystal display (LCD) TVs generally use less energy than plasmas.

LED TVs are slimmer and more easily available, but also more expensive. Plasma screen TVs, on the other hand, are believed to have better picture quality (mostly due to deeper blacks), but are less energy-efficient and usually available in larger sizes.

The main difference OLED TVs have over LED and QLED TVs is how they produce light. Instead of requiring a backlight, the individual pixels on OLED TVs emit light themselves. Removing the LED backlight makes OLED TVs thinner and much more power-efficient than LED and QLED TVs.

How many watts is a Vizio 65 TV? ›

Power Consumption: 103W. Standby Power Consumption: <0.5W.

On average, the latest TVs use around 58.6 watts when running and 1.3 watts while in standby mode. The range of power consumption is 10W to 117W while the TV is on and 0.5W to 3W on standby, and this large range is because there are different technologies and sizes of TVs which result in different power consumption.

But even without investing in smart home tech, you can take account of general electricity costs and what your TV adds to your bill. To put it in perspective, the average no-frills TV costs roughly $30-50 per year to power.

On average, microwaves use about 600 to 1000 watts of electricity. Using a microwave for 15 minutes per day will use about 6.1 kilowatt-hours of electricity per month and 73 kilowatt-hours of electricity per year. A microwave costs an average of $0.86 to use for a month and $10.36 to use for a year.

So, the clear winner here is the lightbulb…at least until you multiply that by how many lights you have in your house. Plus, if you still use incandescent bulbs (switch to LEDs ASAP if you do), 2 – 3 will use more electricity than most TVs over the course of the year.

OLEDs also tend to have slightly higher energy consumption than LEDs, but not if you're using a bright LED TV and watching HDR content. You can use our power consumption calculator above to give you an estimate of how much you'll be spending on electricity annually, but it all depends on the type of content you watch.

But as long as you have the right internet speed to use 4K technology, there's no reason to avoid 4K TVs. That said, it's not worth paying extra until more 4K content is available. The good news is that 4K TVs are becoming more reasonably priced.

How many watts does a refrigerator use? ›

Most typical fridges use between 100-400 watts. To find your fridge's wattage, just: Multiply the number of amps listed on the fridge's nameplate by the voltage (usually around 120).

According to Reduction Revolution, the average refrigerator will use between 1 to 2 kilowatts per hour each day, averaging about $150 per year. If you are curious about how much energy your specific refrigerator uses, you can look up the Energy Guide for your refrigerator's model to get a general idea.

Practically every appliance and electronic device you have plugged in at home is using some electricity — and adding to your utility bill — even when it isn't in use or even turned on.

The Department of Energy estimates you could save 10% every month when you unplug appliances when not in use. Unplugging appliances can save electricity, so make it as much a habit as when you turn off the lights to conserve energy.

All things plugged in will bleed some energy. Called "standby" electricity loss because it's so often associated with electronics in standby or idle mode, it's also known as "phantom" or "vampire" electricity (for obvious reasons). Even turned off, many appliances keep drawing power.

Gaming: 3x HDMI 2.1 (4K/60 Hz), VRR, ALLM, Gaming Mode (input lag <20 ms) Network : Smart TV Vidaa U 5.0, Wi-Fi, Bluetooth , Alexa, Google Assistant, Ethernet. Sound power: 20W (2 x 10 Watts) / Dolby Atmos.

According to numbers compiled by EcoCostSavings, the average modern TV is sucking up 58.5 watts while you're using it and 1.3 watts while you leave it on standby.

1. Quality is better than quantity. With a bigger screen, you'll be able to really appreciate the picture quality. Whether that's with a 4K UHD or 8K TV, the picture is near-perfect, no matter how close you sit.

Samsung TVs usually get a fair bit brighter and have better contrast, while LG TVs generally have much wider viewing angles and better smart features. While LG has more OLEDs in its lineup, Samsung has released its own OLED TVs known as QD-OLED, which produce brighter and more vibrant colors than LG's OLEDs.

Is a bigger or smaller TV better? ›

Bigger is better, in most respects — it's more immersive and easier to see, not to mention more impressive when showing off to the neighbors. But if the screen's too big, it won't fit in the space you have. Know your resolution. TVs today offer three resolution options – 1080p, 4K and 8K.

Are those chargers consuming electricity when they're not charging devices? Does it make sense to pull the plug if you're not using it? Yes, say the energy experts! A charger that is not charging continuously consumes about 1 watt in the socket.

Switching off your TV when not in use will do more to reduce energy usage than anything else. Manufacturers have improved standby efficiency - in most new TVs energy usage is typically below 1 watt - so this is an option if you have a new TV, but if you have an older model, this mode may be using energy unnecessarily.

So once your device is at 100%, unplug it. One of the worst offenders of wasting power is your entertainment system. Think of all those little LED lights blinking at you from the TV, cable box, and maybe even your stereo system. These are all wasting energy.

You should disconnect your desktop computer, monitor, laptop, printer, scanner, modem, or anything connected to these elements after use. Turn them off every night and when they are not in active use. It means making a habit of unplugging appliances to save energy and not leaving them in standby mode.

Sleep Quality Can Be Easily Compromised

Falling asleep with your TV on means you're also soaking in blue light from electronics. This can mess with the quality of your sleep by suppressing the production of melatonin, the hormone that keeps your sleep/wake cycle in check.

What's a healthy amount of screen time for adults? Experts say adults should limit screen time outside of work to less than two hours per day. Any time beyond that which you would typically spend on screens should instead be spent participating in physical activity.

Organic Light Emitting Diode (OLED) TVs provide the best picture and use less energy but are expensive. Most TVs today use light-emitting diodes (LEDs) to illuminate a liquid crystal display (LCD) screen.

The most energy efficient type of TV is an LED flat screen. LED bulbs are very energy efficient, so it's no surprise! OLED and QLED use slightly more energy, as each pixel is individually lit rather than using LED backlighting. At the bottom of the list, plasma TVs and lamp-lit LCDs have quite high energy use.

Plasma TVs are less energy efficient than LED-lit LCD TVs. According to Which magazine, a 42 inch screen LED-lit LCD TV will use an average of 64 watts, while an average 42 inch Plasma TV uses 195 watts.

Do flat screen TVs use less electricity? ›

So, a 24-inch CRT TV eats up to 75 to 95 watts per hour. LED TVs use less power as compared to CRTs. More precisely, it consumes 25 to 35 watts of energy.

Screen type – organic light-emitting diode (OLED), light-emitting diode (LED) and liquid crystal display (LCD) TVs generally use less energy than plasmas.

Besides the noted advantages of OLED display, some of the disadvantages include: Shorter lifetime then some other display technologies. This shorter lifetime is mainly due to the blue organic material but lifetime gets better all the time but is also due to moisture migration. Poor sunlight readability.

In terms of picture quality, OLED TVs are generally considered to be the better option due to their perfect blacks and infinite contrast. However, QLED TVs can still produce very high levels of brightness and colour accuracy, and they are often more affordable than OLED TVs.

QLED displays handle motion better than OLEDs since most QLEDs offer variable refresh rates (VRR) and low input lag. Also, QLED TVs are generally less expensive and readily available in most markets, unlike QNED displays.

Reflective Displays

This efficiency is made possible by the principle on which these displays work.

If you have the money to spend and your priority is getting the best possible screen quality from your TV, smartphone or gadget, we'd say that OLED is absolutely worth the money. Your experience with the colours and contrast of movies, streaming shows, documentaries and games will never be better.

OLED (Organic Light Emitting Diode)

Similar to plasmas, OLED TVs and monitors are capable of producing true blacks for life-like picture quality. They also have impeccable viewing angles, meaning that the picture doesn't shift in color and contrast when the display is viewed at skewed angles.

And don't forget, a TV with an OLED screen is very thin. The bezels around the screen and the casing are often just a few millimeters thick. OLED TVs also consume less power than plasma televisions. All of these properties make OLED televisions the most worthy successor of your plasma TV at the moment.

Manufacturing of plasma displays for the United States retail market ended in 2014, and manufacturing for the Chinese market ended in 2016. Plasma displays are obsolete, having been superseded in most if not all aspects by OLED displays.

Does leaving TV plugged in waste electricity? ›

The short answer is yes! A variety of different electronic devices and appliances, including televisions, toasters, lamps, and more, when plugged in, can consume electricity even when they're turned off.
