Previous Next. Nov 14, 3, 0 0. Thinking about picking up a new television. Size between 42 and 60 inches. Jul 8, 6, 2 The bigger you go, depending on the distance you sit from the screen, the more of a difference you're going to notice Personally, I would be ok with a p set up until about ". Once I hit 51", I'd really prefer to have p. I have a " p projector that I sit roughly 12' from and can notice the space between pixels sometimes. Nov 26, 14, I'm also in the holiday LCD tv market.
I sat at roughly 9 feet from both TVs. With Sorkin's latest wordfart "The Newsroom," the Samsung's better contrast ratio made it the clear winner. The Seiki looked washed out and flat. Shadows and black objects looked gray. The Samsung looked more real. There was very little difference in apparent detail.
The Seiki looked more smeary, while the Samsung had combing artifacts thanks to mediocre deinterlacing. This is where you'd expect things like textures in objects, hair, and wrinkles to really pop out on the Seiki, except In some cases, it looks more detailed.
There are a few things going on here, as to why the extra resolution potential of the Seiki isn't translating to extra visible resolution. The first, and most important: I'm too far away. I've written multiple articles about this , as have many others , but the fact is, your eye has finite resolution. From a certain distance, your eye can't resolve the difference between p and Ultra HD. With TVs this "small," your eye can't even tell the difference between p and p, never mind 4K.
So all the extra pixels on the Seiki are wasted. If you're curious if you'll be able to see the difference from where you sit, with your eyes, and whatever TV size you want to get, check out Chris Heinonen's excellent 4K Calculator.
Why was I sitting at 9 feet? Studies have shown that most people sit between 9 and 10 feet from their TV called the Lechner distance. If you sit closer, good on ya, but you're on one of the slopes of the bell curve.
Personally, I usually sit 8 feet away from a inch screen , so I'm way on the flat tail of the curve. At 9 feet, 50 inches is way too small to need more than p resolution. At that distance, 4K has dubious merit even on a inch TV. There's more to it than that.
A p HDTV will be able to display p broadcasts natively. Displaying a signal without conversion results in an excellent picture.
Once the TV has to convert a signal, the conversion process itself can degrade picture quality. Therefore a p broadcast might look better on a p TV than on a p, if the processor chip in the p HDTV is not up to snuff.
Other networks broadcast in i, which the p HDTV can display natively. A p set will have to downconvert a i signal before displaying it. Both HDTVs will also have to de-interlace the i signal but this does not involve changing the resolution, only reordering frame display.
What happens when you feed a p signal to p TV? Assuming the TV can accept a p signal, it will be scaled to p. But the caveat is that many older p and even some p models cannot handle p signals at all.
In which case, you'll get a blank screen. Thankfully, most newer HDTVs can accept p signals. It's converted to p with no resolution conversion. Instead, the i signal is deinterlaced for display in p. Some HDTVs perform a better job of this deinterlacing process than others, but usually the artefacts caused by improper deinterlacing are difficult for most viewers to spot.
Side by side, how do p and p TVs match up in head-to-head tests? We spend a lot of time looking at a variety of source material on many TVs in our labs. Over three years ago, many p TVs weren't as sharp as they claimed to be on paper. By that, we mean a lot of older p sets couldn't necessarily display all 2 million-plus pixels in the real world — technically, speaking, they couldn't "resolve" every line of a i or p test pattern.
That's changed in the last few years. Virtually all p sets are now capable of fully resolving these materials, though not every p TV is created equal. As our resident video guru, senior editor David Katzmaier, explains, Blu-ray serves up p24 video format which not every TV can display properly. The 24 refers to the true frame rate of film-based content, and displaying it in its native format is supposed to give you a picture exactly as the director intended you to see it. Whether you're dealing with p24 or video-based p50 doesn't alter our overall views about p TVs.
We still believe that when you're dealing with TVs 50 inches and smaller, the added resolution has only a very minor impact on picture quality. In our tests, we put p next to p sets, then feed them both the same source material from high-end Blu-ray players.
