a 14 year old full HD television or a new 4K projector?

I'm probably one of the few people who hasn't bought a new television in ages.

To be more precise, it has now been an impressive 14 years.

But how does my outdated TV compare to a state-of-the-art 4K projector with modern technology in terms of power consumption?

This article clarifies that, including a look at the annual costs and a comparison with the rough power consumption of modern televisions.

The duelists in detail: My Full HD TV is the Philips 46PFL7605H, which I have already had competing against an 8K TV in terms of image quality.

Opposite him is the new 4K projector Xgimi Horizon Ultra.

Interestingly, the price of the two devices was in a very similar range when they were released.

However, the 46PFL7605H cost around 400 euros less shortly after its release and only half as much a little over a year later.

Times are changing: Nowadays, most televisions are not only significantly larger, but 4K has long been the current standard.

This is also shown by a look at our large buying guide for televisions in 2024.

TV versus projector: The measured values

I compare the television and the projector at maximum brightness and standard settings.

The exact consumption may vary slightly depending on the content displayed. The values ​​mentioned below reflect the typical consumption in my domestic usage scenario very well.

• TV power consumption: approx. 125 watts
• Power consumption of the projector: approx. 200 watts

Incidentally, the information for the projector applies both when it displays the image in full size and when it is reduced to around 95 inches, in which I actually use it for test purposes.

When watching Dolby Vision content like Shogun on Disney+, the projector's consumption was around 30 watts lower, but this was also noticeable in a slightly darker picture.

What is 4K and do you need 8K?

What does this mean for annual electricity costs? This depends on how long the device runs.

Assuming two hours per day and the average price of electricity according to the Federal Statistical Office the following difference results:

• TV: 0.125 (kilowatt) * 2 (hours of operation per day) * 365 (days per year) * 41.75 (cents per kilowatt hour) = approx. 38 euros per year
• Projector: 0.2 (kilowatts) * 2 (hours of operation per day) * 365 (days per year) * 41.75 (cents per kilowatt hour) = approx. 61 euros per year

Doubling TV time also means doubling costs.

If you watch a lot, you will spend around 76 euros for the television and around 122 euros for the projector per year.

What is HDR? – High Dynamic Range explained

This depends on various factors, especially the size and the question of whether HDR is used or not – a technology that my old television from 2010 obviously cannot handle.

The panel used (OLED, Mini LED and so on) also potentially plays an important role.

The following information is for rough guidance only.

Depending on the exact model, TV settings and content displayed, the values ​​may vary from what you may measure at home.

Approximate power consumption of current televisions

The consumption of my old TV is comparatively high: Nowadays it is quite possible to buy a television that is not only larger and has a higher resolution than my old Full HD TV, but also uses significantly less power.

At least when it comes to SDR representation.

However, if HDR comes into play, the consumption is quickly higher than on my television from 2010, although with clearly visible optical advantages.
