Think you're getting a 120Hz TV? Hold up just a second. You might not be. Many TVs today are 60Hz, despite having "motion rates" and "effective refresh rates" claiming much higher numbers, including 120, 240 and more. TV companies are deliberately hiding the actual refresh rate from you, and it's been going on for years.In some cases some 60Hz TVs have performance that might be slightly better than a basic 60Hz TV, but lacking the hardware of a true 120Hz TV, they can't offer nearly the same motion performance.A true 120Hz refresh rate can improve the picture quality a bit by reducing motion blur. It's not a massive factor for most viewers, however, which is why 60Hz TVs like the TCL 6 series and Vizio M series can still rate excellent image quality in CNET reviews. 19 The TVs of 2018 are here! Now wait for the price drops On the other hand, true 120Hz makes a TV more expensive to manufacture, so it's rarely found in budget or even midrange TVs. And … [Read more...] about Beware fake 120Hz refresh rates on 4K TVs

As we all expected, the big news at CES this year was Ultra HD 4K displays. It seemed that every TV manufacturer had one, ranging from massive LED LCDs to midsize LED LCDs to midsize OLEDs. We've talked about this before, but now with more info, and definitive product announcements, let me explain in exacting, excruciating detail why 4K TVs are still stupid. Allow me to start with the most important point: 1. I love 4K 2. The eye has a finite resolution Try this. Go to the beach (or a big sandbox, or a baseball diamond). Sit down. Start counting how many grains of sand you can see next to you. Now do the same with the grains of sand by your feet. Try again with the sand far beyond your feet (like, say, 10 feet away). The fact that you can see individual grains near you, but not farther away is exactly what we're talking about here. The eye is analog. Randomly analog at that. So of course some people are going to see more detail than others, and at different distances, but … [Read more...] about Why Ultra HD 4K TVs are still stupid
If you listen to the marketing from TV manufacturers, it seems TVs with 4K resolution will deliver a massive boost in picture quality.And, if you're lucky enough to actually have a source of real 4K video -- one with the same 3,840x2,160-pixel resolution as 4K TVs -- you may well be able to see additional detail. (4K TVs -- also known as Ultra HD sets -- are so named because that 3,840-pixel horizontal resolution is almost 4,000 pixels wide. 4K TV is less of a mouthful than 3.84K TV.)But real 4K video sources are still few and between, which means most of us will be watching content in good, old-fashioned "regular" high-def: 1,920x1,080 (1080i or 1080p) or 1,280x720 (720p), both of which have far fewer pixels than 4K.Since that'll be the case for many years to come, how much would a 4K TV actually improve the picture? The short answer is that a 4K TV could improve the picture a bit in the best cases -- but don't expect miracles. Most 4K TVs use a process called upconverting (or … [Read more...] about Can 4K TVs make ‘regular’ HD content look better?
LAS VEGAS--Today Sony announced one of the broadest and most compelling product and service lineups at CES 2013, including 4K and OLED TVs, the first way to get 4K content into the home, and yes, an actual smartphone. Leading the charge was the company's new flagship smartphone, the Xperia Z. With quad-core processing, a massive 5-inch screen, and a 13-megapixel camera, it has the specs to compete with the best phones on the market. And one of the only ones that's water-resistant. Now Playing: Watch this: A look at Sony's premium high-end Xperia Z 1:53 Next the company talked up NFC, or near-field communication, saying it had integrated "One Touch" communication among devices to ease media transfer and streaming among phones, tablets, TVs, and audio devices. The idea is that the link can be established just by touching the devices to one another. Next up was a discussion of the company's new Triluminos display technology branding, said to improve color fidelity. Vaio PCs … [Read more...] about Sony CES press conference: Heavy on 4K TVs, OLED, plus an actual phone!
There's a simple rule of thumb for companies that market electronics: When it comes to specs, a higher number is usually preferred. Sure, there are exceptions -- you want things like response time, load times and mobile device weight to be low -- but generally, more equals better. It comes down to the "speeds and feeds" aspect that still dominates a lot of tech shopping: When you line up a bunch of similar TVs, phones, laptops or tablets, the ones with the higher numbers get the edge. Think about battery life, display resolution, screen size, processor speed, memory and storage capacity, to name just a few. Of course, the quoted number is often only half the story. Consider the megapixel myth of digital cameras: a 15-megapixel camera isn't necessarily going to yield a "better" picture than an 8-megapixel shooter. Nor is a 4K Ultra HD TV -- with a resolution of 3,840x2,160 pixels -- going to necessarily outshine a "standard" HDTV with 1,920x1,080 pixels, or just one-fourth of the 4K … [Read more...] about The truth about Ultra HD 4K TV refresh rates
