There's a sweet spot with any TV, it's just a matter of finding it. It's possible, though rare, that you have a TV with permanent edge enhancement. Even turning the sharpness control to zero and going through every setting and picture preset in your TV, you still may see edge enhancement or other processing. This was more common with older TV sets, though. These days it's fairly rare.
Many TVs and some high-end projectors have processing features separate from the sharpness control. These are usually deeper in the settings menus, or in separate "advanced" sections.
Some of these can enhance the apparent detail without adding undue amounts of edge enhancement. Others, of course, do more harm than good. Part of this is due to the increase in overall processing power available in mid- and high-end TVs. For instance, Samsung, LG, and Sony have discussed using AI for their upconversion , which is how you get a decent-looking lower-resolution image on a high-resolution television.
There's no blanket advice here. Sit close, and see if it's adding noise, edge enhancement, or if it's making the image appear sharper. Purists will likely want to keep these features off, especially with high-quality content like from a 4K Blu-ray, but with some content it might help. Occasionally, the edge enhancement is in the source. This was common on early DVDs, where edge enhancement was added to make them "pop. It's just something to keep in mind if you're trying out different settings, don't use just one source or program.
TV manufacturers love edge enhancement, largely because it makes their TVs seem super detailed when viewed in a store. There are also some sources, generally low-quality video like standard-def TV channels or even VHS tapes, that can benefit from a TV's detail enhancement circuits.
These sources are so soft and low-resolution to begin with, that when blown up to the size of today's large televisions they may look better enhanced. If you go to your TV right now and turn the sharpness control all the way down the picture is absolutely going to look soft. If you're experiencing the soap opera effect on your television then you should try dipping into the video settings and dialing down or disabling the Motion Interpolation. If you're watching something and you start to notice the soap opera effect, try changing these settings.
Most televisions should remember the individual picture settings for each HDMI input, so you can change it for your Blu-ray player without effecting your PVR, or vice versa. I've found that dialing it down from Standard to Clear helps combat the soap opera effect, but you'll need to play around with these settings on your own television and find what looks best for you. The Custom option even lets you adjust the blur and judder reduction independently.
I've also found that dialing down Motion Plus reduces unintended pixelation in fast-moving scenes. You really notice it when you look at the wheels of a moving bicycle or motorbike -- perhaps while watching the Tour de France or a motorbike chase such as across the rooftops of the Grand Bazaar at the start of Skyfall.
You expect the spokes to be a blur but Motion Plus tries to compensate and you end up with spokes which look like a pixelated mess. Turning down the Motion Plus helps reduce this effect. But we live in an age of wonder and delight. Did you really luck out and get a 4K set? Well, you actually have a growing number of options for content there, too. Those services use different codecs, though. Tim Moynihan covers hardware for Gadget Lab, with a concentration on cameras, TVs, Ultra HD video, virtual reality, and the weirdest things he can find.
I was drawn to a massive Samsung QLED TV displaying unnervingly vibrant images of sizzling butter, exploding flowers, yellow snakes, and various colors of rippling fabric.
Another was airing a soccer game, and, despite being in a scentless commercial non-place of a big-box store, I felt as if I were on the pitch with the sweaty players. It all looked quite amazing, a reminder of how high-definition digital technology has upped our tolerance for the hyperreal onscreen to the point where sometimes it can feel more real than, well, reality. If I had to watch all of these clips on the same TV — the exploding flowers and sizzling steaks and stretching fabrics and soccer players and then the film trailers — I might have come to the conclusion that movies today, by and large, look like crap.
This is because TVs now deliver images faster than movies do, and TV manufacturers have tried to make up for that discrepancy by souping up films through a misbegotten digital process called motion smoothing. And however well-intentioned it was, most people hate it. Motion smoothing transforms an absorbing movie or narrative TV show into something uncanny. The first time many Americans heard of motion smoothing may well have been in December, when Tom Cruise, decked out in a flight suit on the set of his Top Gun sequel, stood alongside his Mission: Impossible — Fallout director, Christopher McQuarrie, and issued a PSA imploring viewers to turn off motion smoothing.
Here was the normally press-shy Cruise showing up in a video not to promote a new movie but to tell us to change a setting on our TVs. Other filmmakers had been protesting the technology for years. Martin Scorsese wrote to encourage her. Motion smoothing is unquestionably a compromised way of watching films and TV shows, which are meticulously crafted to look and feel the way they do. But its creeping influence is so pervasive that at the Cannes Film Festival this May — the same Cannes Film Festival that so valorizes the magic of the theatrical experience and has been feuding with Netflix for the past two years — the fancy official monitors throughout the main festival venue had left motion smoothing on.
And what films were supposed to look like will be lost. Most movies and narrative TV shows are shot at 24 frames per second, which has been the traditional rate for motion-picture film since the late s, when sound was introduced. TVs, however, have always had a higher refresh rate per second, denoted in hertz.
