Does Standard Definition DTH channel looks good in 32" Full HD 1080p LED TV compare to 32" 720p LED TV?
I have to disagree with the folks that answered that it makes no difference in quality viewing a standard definition signal on a full HD 32" LED TV. The quality difference is quite noticeable unless your TV has upscaling built into it's video processing. I have an old 32" HDTV that doesn't have this feature and the picture sourced from standard def TV or VHS tape is horrid by current standards. Switching to my 50" HDTV with upscaling noticably improves the image, at any distance. BTW, viewing distance can be a critical factor in viewing your TV regardless of resolution. The standard for optimal viewing (established for viewing art and photography) is to view from three times the diagonal measurement of the object being viewed. This means the optimal viewing distance for your 70" LED TV is 17 feet 6 inches (!).
How much longer will it be before 4k becomes an "old" standard along with 1080p and below?
Any spec can be considered “old” as soon as a newer one emerges. But at the moment, we are past the point where one standard simply displaces another, the way that digital/HD has made standard-def (NTSC/PAL) analog television obsolete.Rather, all the new and on-the-horizon improvements (4K, WCG/HDR, even 8K) can be seen as extensions of existing digital standards. The key to this is that the new features are generally both upward and downward compatible with existing technologies: upward compatible, in the sense that a new 4K HDR display will continue to receive and display “regular” HDTV (1080p/1080i/720p etc.) signals, and downward compatible in that a 4K HDR player will include the capability to output signals that a legacy HDTV can interpret and dispaly.So while 1080p may be an “old” standard, it is not an obsolete one, and is unlikely to become so for a very long time. This is because 1080p (and the other HD variants) is, in fact, close to ideal for many applications — this is no accident, as factors such as visual acuity and other human factors were considered in developing the HD specs. While it is true that, due to production economies of scale, most new panel development is moving to 4K resolution, it’s also true that very few of these sets are being used to view actual 4K/HDR content, and most of the users of these sets are perfectly happy with what they have.This is even more true with the 4K to 8K jump. There is really very very little need for 8K in a consumer environment, until we get to some sort of flexible wall-sized display technology (and even then the focus will be on 8K displays rather than content; the full screen at full resolution will probably be seldom-used, rather sections of the screen will be used to display at “very good” resolutions). 4K already represents a strain on the digital-delivery system in many places (and in fact the 4K you get from streaming services is likely to be compressed in ways that mostly negate the advantages of 4K over a less-compressed HD signal anyway). 8K content, requiring 4x the bandwidth, simply does not justify itself, even where bandwidth is plentiful.So the current digital standards (which incorporate 4K/HDR/WCG along with legacy HD resolutions) will be in play for the forseeable future.
Directv looks bad on my 4k vizio e series!?
PS4, Netflix, etc. looks amazing crystal clear but however when I go to watch tv it looks grainy or very poor. I'm not sure if I need to change the settings or could it be since it's only 1080p?
What is the difference between SDTV, EDTV, and HDTV?
It's quite simple. It boils down to resolution. Sound and aspect ratio is another benefit of HDTV, but not the biggest advantage. SDTV is 480 interlaced lines (480i). EDTV is 480 progressive lines (480p). HDTV is 720 progressive (720p), 1080 interlaced (1080i) or 1080 progressive lines (1080p). Instead of going into detail between interlaced and progressive, you just need to know that progressive will present a cleaner picture (no jagged edges). Higher resolution, the clearer the picture is. The reason why you see a difference is because you are receiving a cleaner signal from DVD. If you consider the distance and interference a signal has to go through to get to your house, it is understandable why a standard tv signal would look bad. On your TV, you are still seeing a 480i signal. Just a cleaner 480i signal. If you compare cable tv and DVD, you will see less of a difference. Cable companies do many things to amplify and improve the broadcast. Most standard tube tv's are native 480 interlaced resolution and only support that. It cannot support 480p, 720p or 1080i. If you want to get higher resolution and EDTV or HDTV support, you need to upgrade to a plasma, lcd or dlp tv. There is no point in downconverting anything to composite. Composite is going to always provide a horrible signal.
