However, if done as unintelligently as it has been by most TVs for years now, this can sometimes just feel like a TV is turning HDR into SDR during dark room viewing, so extreme is the amount of light that’s being taken out of the picture.
The assumption being that you can manage in darkened rooms with less brightness and so use less power.
One of the most common Eco mode implementations is to use light sensors built into a TV to monitor ambient brightness levels, and adjust the picture accordingly. With all this in mind, we have to say that pretty much our first job when reviewing a new television is to turn off its Eco features, so we can be sure we’re getting a proper idea of what the TV is actually capable of. Don’t forget, either, that HDR is designed to make images look more lifelike, but it’s hard to do justice to footage of a sunny day when your TV is only using a fraction of its brightness potential.
Reducing brightness also affects a screen’s perceived contrast, the amount of colour volume it can show, and the amount of detail you can see in dark areas. Now that HDR is a well-established part of an AV fan’s regular viewing life, though, reducing brightness is inevitably going to heavily affect both the impact and the accuracy of a screen’s HDR presentation. This is hardly surprising the most direct way to reduce TV power consumption is simply to limit the amount of brightness a screen pumps out. In fact, this problem – especially when high dynamic range ( HDR) technology started to appear on the horizon – certainly didn’t help plasma’s fight against extinction.īrightness remains the area where Eco settings typically have their biggest negative impact on picture quality. We first became aware of just how much of an impact Eco matters can have on picture quality way back in the days of plasma technology, where we heard from multiple brands that they’d had to substantially rein-in the potential brightness of their plasma panels in order to avoid falling foul of TV energy regulations. Before you all rush off to make sure that your TV is running in its Eco mode, though, there’s one pretty significant downside to consider: Eco modes can really mess with your picture quality.
