TV‘s and Energy efficiency
Main Post:
Hello, I’m new to this forum and don’t know if it’s the right place to ask my question.
I‘m from Europe, living in Germany and want to buy a new TV. It should be a 65“ one. So far so good, I‘ve seen lots of 4K hdmi 2.1 (important for me for gaming) TV’s. I‘m mostly interested in Mini-Led TV‘s because they‘re superior to LED ones and don’t have the risk of a Burn-In like OLED‘s, downside is, they all have bad energy efficiency when it comes to the European energy label. Usually, they come with a „G“ on a scale from „A“ - „G“. Some of them have „F“. However, in 2023 the ones labeled with „G“ should disappear from the market, by not being able to sell those anymore.
My question is, should I wait until 2023 to buy a new one? Is there a lot energy saving potential? And if there is, is it a lot?
Top Comment: I don't understand why energy efficiency bothers you in a TV. Modern TV's aren't like the days of Plasma that throw out power like a space heater. Realistically you're not going to notice that much of a difference in your energy bill and if that bothers you, I would argue that instead of buying a TV you should concentrate on other areas of your life first to allow you to afford the running cost of the TV. No point buying a Mustang if you can afford the car but can't afford the fuel and maintenance costs.
Tv vs Projector energy usage
Main Post:
Which has typically better energy rating, TVs or projectors? Is an 80 inch LED TV comparable in energy consumption to a projector, assuming each ran for about 3 hours a day?
Top Comment:
Which TV and which projector? They should have power consumption ratings on them.
Another Fire TV advantage vs Cable - energy consumption cost savings.
Main Post:
A single Fire TV 4K consumes 4 watts while showing video and less than 1 watt while in standby.
By comparison, a Comcast set-top DVR (CISCO or Arris or Pace) consumes about 28 watts while in use and 25 watts while in standby.
If you live in Hawaii (electricity cost $0.351 per kWh), have one box, and the box is awake 5 hours a day, you are paying $6.57 per month in electricity to operate that cable box.
A single Fire TV 4th gen awake that same 5 hours a day costs you only $0.42 per month. That saves you over $6/month!
The amount of savings varies based upon your local cost of electricity (e.g. the California average is $0.1559 per kWh, so the savings is $2.73 per month per set-top box).
Just another savings of streaming services vs. buying cable.
Top Comment: Whats even more sad, Most Americans do not know what a kWh is, how power is billed or how to lower their usage. I grew up with the 'Were you raised in a barn?, close that door', 'Does money grow on trees? TURN THOSE LIGHTS OFF'. I currently have tried for five years to cut the cord with DirecTV, I paid $0 for three years, now I'm paying $18/mth for DirecTV. I only have it for the NFL Sunday Ticket.
"Energy Efficient TV" No thanks.
Main Post:
So, I am staying at a Fairfield Marriott for two weeks. Checked in last night, and was quite confused that my TV was so dark I could barely see it. A quick check of the remote (some Enseo hotel remote or something) verified that there are no options to turn this brightness up.
Still confused, I walked back down to the reception desk and inquired about the problem, and was told that "Marriott sets the TV's up that way to conserve energy."
Well now.
I mean, yeah, I get it. Conserving energy is good and all that, but I didnt pick the Marriott because I wanted to squint at my TV for two weeks.
So, I fiddled with the little Enseo box attached to the back for a bit until I realized the TV was adjusting its own brightness based on the ambient light in the room. I like to watch TV or play some games in the dark, hence the dark picture.
Solution? Plug my phone into the charger and run the flashlight in front of the sensor. TV is now bright as can be.
Ironically, by prohibiting me from setting my own brightness setting, Marriott is now expending literally twice the amount of energy than they would have if they didnt mess with the TV in the first place.
If anyone from Marriott management reads this - come on mate. If I wanted to conserve energy that badly, id be sleeping in a tent. Saving energy is great, but this legit hurt my eyes until I figured out the workaround.

What brand of TV is it?
You may be able to go by Walmart/Target and buy a cheap universal remote and try to open up the settings menu to disable it. Then return the remote if you wish.
There also may be a small wire connected to the TV on the back that looks similar to an RJ-11 or RJ-45 wire, sometimes unplugging that may help as well.
Energy consumption questions -ambilight TV
Main Post:
Hi guys, sorry if this question has been asked before, just struggling to find a general answer.
I have an Ambilight TV and have the Ambilight on pretty much all the time. I'm in the UK and due to an issue with my electricity supply I can't get a smart meter so I am a bit blind to my appliance energy consumption. As the UK is currently going through a bit of an energy crisis I'm trying where possible to reduce my energy consumption.
My basic question with that in mind, is: does Ambilight tend to use much more energy for you? Is it worth switching it off regularly or does the consumption tend to be negligible.
I understand that I could calculate this with a meter, but I'm hoping for a general answer rather than calculating it to the exact KW.
Many thanks in advance!

Apple TV 4K (2017 vs 2021 vs 2022) power draw
Main Post:
This is for the nerds that like to explore behind the scenes. All of the power draw is 1) total device power draw and 2) below 6W AC, so any changes won't be noticeable to consumers (except perhaps in very long 4K HDR streaming and you put your hand on the box?).
115V input 2017 4K - A10X 2021 4K - A12 2022 4K - A15 Sleep / Network standby 0.29W 0.40W 0.49W Streaming 4K Movies 2.86W 3.21W 2.35W Streaming 4K HDR Movies 5.77W 3.41W 2.31W Power Supply Efficiency 88.1% 88.3% 88.3%Most video decoding is done with fixed-function (e.g., dedicated) silicon, rather than the CPU or the GPU itself. Notably in the 2022 model, 4K HDR actually consumes a smidge less power (-1.7% / 0.04W) than 4K non-HDR.
Some quick notes on 4K HDR:
- 2017 is 4K30 Dolby Vision HDR, no Thread
- 2021 is 4K60 Dolby Vision HDR, has Thread
- 2022 is 4K60 Dolby Vision HDR and HDR10+, sometimes has Thread
Why has idle power gone up? It's a tiny change in absolute terms (0.29W → 0.40W → 0.49W): maybe the always-on Thread Border Router (in 2021 + 2022) and AC-DC (PSU) things?
Apple's methodology
- Sleep/Network standby: Low power state that is entered automatically after 15 minutes of inactivity (default), selecting Sleep Now from Apple TV 4K with Siri Remote Control Center menu, or by pressing the Power button on the remote. To deactivate network ports, remove power.
- Streaming 4K movies: Condition in which 4K movies are played on Apple TV 4K with Siri Remote from Apple TV app.
- Streaming 4K HDR movies: Condition in which 4K HDR movies are played on Apple TV 4K with Siri Remote from Apple TV app.
- Power supply efficiency: Average of the power supply’s measured efficiency when tested at 100 percent, 50 percent, and 20 percent of the power supply’s rated output current.

Top Comment: Those are actually pretty good figures. Compare this to a conventional LED lightbulb, which draws around 7 W of power.
