HD TV without HD service, image quality?




Kxnny


I just bought a new HDTV and I got a regular DirectTV box and it runs on those red/white/yellow connectors and I was wondering if I upgraded to a HD DirectTV box with HDMI connector but without the HD service, would my image improve? Or does it not matter. I just want it to have better quality image. The guide that comes with it says that the A/V(red/white/yellow connectors) have the lowest quality image.
Better image quality on my Direct TV that is. Also those channel I watch will not have HD, I don't care about the HD I just want to know if the image would improve from A/V connection to HDMI connections on Direct TV
Well it is a bit blurry in the background at certain images.... it is a 40inch led lcd 1080p 120hz Samsung 6300. I just want to know if i can get rid of those blur if I used a hd box instead regular ones.... i dont care about HD, I'm using it to watchin asian channels that dont offer HD.....



Answer
1 ) HDTV connect to regular Direct TV box via RCA red/white/yellow cable = normal pictures quality.
2 ) HDTV connect to HD Direct TV box *without the HD service, via HDMI cable = normal pictures quality , because the " signals still normal resolution not HD 720P resolution .
3 ) HDTV connect to HD Direct TV box *with HD service / paid for HD services via HDMI cable = better pictures quality / better image from HD channel ( but not all channel are HD ) , because the " signals is digital 720P resolution and you HD TV will display up to 720P resolution.
4 ) All HD TV built in digital tuner ( ACST in USA / DVB-T in European ) , you can get free view on air TV channel with HD 720P resolution , plug in you out door antenna you also enjoy HD TV from some HD channel. * in door antenna may be not so clear, depends of area *
keeps in mind . Pictures image depends of you TV " quality ". also you in-put signals.
you in-put source master the display resolution . if you in-put is only 480P resolution to you HD 720P TV even 1080P TV, you get max 480P resolution display. is nothings to do with RCA cable or HDMI. of course only HDMI able to handle / transfer digital 720P / 1080 P signals.

regular boadcasts on HDTV?

is it true that while watching regular broadcasts on an HDTV the image quality is worst than on a regular TV?


Answer
YES, you are correct. HDTV's were designed for HDTV, not for "Analog" or "regular" TV broadcasts. Although your HDTV WILL display regular TV, the comparison can be like night and day. The analogy is like a porche, it will run on "Regular" gasoline, but to perform properly, it needs "premium" gasoline. Analog is considered "Regular" gas, and it is most likely feeding your TV only 480 lines (or much less in most cases!) of horizontal resolution, yet it requires as much as 1080 lines to run to it's maximum potential. So, what most HDTV's do is take those 480 lines and "convert" them into 1080 lines. Now, if the 480 lines have ghosting, static, and poor colors(which is probably the case with lousy analog anyhow), the TV will have to do the "Mathematics" and try to turn 480 lines into now 1080 lines of ghosting, static and poor color. Now it did it, your HDTV just made your lousy "Analog" TV even worse, and you didn't have to lift a finger. There are some premium brand HDTV's (Sony, Samsung,LG)in the market that can "Convert" the regular TV better, by using "Scalers" and up to 6 "Processors" that can initially "Clean-up" the analog TV, remove static and noise, and purify colors, and make it look closer to HDTV when "Scaling" to 1080. In comes the cost, and the preverbial "You get what you pay for". Finally, to answer your question as to why analog tv looks better on your old tv. That's because your OLD tv was actually design FOR regular tv, and the manufacture designed it to do well with that type of broadcast. Good luck, and don't forget to rate me.
