Do you I think I have made a big mistake by buying a 720p TV ?

Post by linux_rules » Sat Aug 17, 2019 7:14 am

Hi,

I have purchased this TV
https://www.panasonic.com/in/consumer/h ... 200dx.html

My digital cable provider has given me a 1080i set top box.

The picture quality of HD channels is not bad but still what is your opinion ?

I guess you cant return it back to the store any more? You could always ask if it's a local store. Even with internet purchases in most countries you can return your purchase within 2 weeks.

But if you cant return it any more and the picture quality is good, I shouldnt worry to much about your tv being 720p or 1080p. If the source of the picture quality (dvd / blu-ray / 1080p is good, what kind of monitor you have is less important. You said it yourself that the tv signal quality was good. That's what counts. Hdready, Full Hd, 4K are made to be much more important than they actually are in practical use. Tv is always watched from a distance and picture quality differences are less noticeable from afar.

If you're referring to TVs only, then yes. If you're referring to computer monitors as well, then no.

No, I cant return it. I purchased it from a store 3 months back.

That's exactly what the sales person at the store told me.

I guess I won't worry about it anymore.

Thanks to both for replying.

I don't think you made a mistake at all. Resolution isn't the only thing to consider for a tv. Contrast ratio, dynamic range, and other things matter.

If the quality of the picture is great, then stick with that one. I would choose a 720p tv that looked good than a 1080i that just looked ok.

Yes, a big mistake, as per https://en.wikipedia.org/wiki/High-defi ... ted_States - List of current American high-definition channels

A large 39" TV looks better at 1080i/p compared to 720p, but not at 4k or 4000p(= no visually discernable difference). IOW, 720p is optimum-looking for TVs smaller than 30".

4k only looks better for TVs larger than 55", at a normal viewing distance of about 6 feet away. 4k screens may be a waste of money on a stand-alone 14" laptop or 17" monitor, even though at a closer viewing distance of about 2 feet away. OTOH, 2k or 4k is useful on 6" smartphones that can be used in VR headsets(= viewing distance is about 2").

Netflix streams are at 4k maximum. Youtube streams are at 1080p maximum. Pay-per-view and VoD from the Internet are usually at 1080p. DVD and Blurays movie discs are often at 1080p or 4k.
....... Video streaming at 4k consumes a lot of data, eg about 8GB per movie in 4k, and requires a minimum download speed of about 15Mbps.

In my case, my cheap Internet plan limits me to 480p video-streaming on my 1080p Android 10" tablet. 360p is tolerable and 240p is blurry on my tablet.

That a 720p TV is decidedly suboptimal given 1080 (i or p) source. See, your television has to scale down the 1920x1080 source image to your TV's native resolution for display, and proper downscaling is in fact a relatively involved process; needs fair processing power. Your TV being 720p in this day and age will however mean it's also very much at the cheap end; will not have processing power to spare. This means the TV's scaler will produce quite a few scaling artefacts, very likely most easily noticeable with for example (fast) sports.

Now, of course, if you're sure you're not noticing any this could be ignored -- but I'd advise you to not in fact be sure until you have compared it to to a 1080p TV sitting right next to it, displaying the same source.

That is, I would find the above replies a bit overly "friendly". Certainly I would myself not buy anything under 1080p "these days" -- and in fact for a definition of "these days" which already easily spans more than 5 years. Sorry...

[EDIT] By the way, if you can set your set top box to 720p output its scaler might outperform your TV's built-in one.

Thanks for replying.

All I can say is the mistake is already made and I can do nothing about it.

This TV is not actually cheap (in my currency).

I will use it as long as it lasts and will try to make better judgements while buying

my next TV.

If you have a lively local second-hand market I'd try and flip it. "New, with all accessories and original packaging!". Many people wouldn't even have enough of an idea to ask such as you did...

Please don't take this in a wrong way. I am not trying to ignore what you wrote but frankly speaking I find nothing wrong with this TV. Despite the fact that the TV is performing the
"processing" to downscale to 720p there are no artifacts that I can see. The picture quality is
actually quite nice on HD channels.

The only reason I asked this question here is coz the difference in price between this (720p) TV and 1080p TV was not that great in the store. The sales person at the store suggested that if I watch the TV from a certain distance I won't notice the difference.

Oh, he is definitely right. I also notice absolutely nothing from 20 meters away. But, certainly all fine then. The fact that you posted the question in the first place seemed to indicate doubts and as such I did not think the initial replies were being too helpful, but as said, if you're fine, then all's fine.

Certainly Panasonic is one of the better TV brands generally, and I've for example been impressed by my own Panasonic's upscaling from 720p (DVD) to 1080p. In my own region 720p counts as older by now but I see your model is not in fact very old yet; that will offset what I mentioned about available processing power.

By the way, I take it from Google results you're likely in India; I have no idea about Indian TV infrastructure but while you said that your set top box is 1080i, do make sure it is not in fact upscaling an original 720 signal for compatibility with 1080 TV's. Probably not since in that case 1080p would be more expected but still: if the original signal is in fact 720 than all you'd want to do is configure the set-top box to not scale at all; to either only de-interlace or do nothing at all and let the TV take care of that as well...

Well, that's explicitly a list of HD channels (i.e., 1080 channels) which, I assume, doesn't necessarily coincide with your cable provider's channel list (and/or resolution; maybe it provides the channels as SD, i.e, 720. My own provider provides both for the basic, standard channels).

Of course, if that list does coincide with what you actually get delivered then we can forget about not needing downscaling...

Then you made a mistake. HDReady looks good on smallish TVs (up to 32"). This one is already exhibiting low pixel density and you have to watch from afar i.e. 3m minimum not to notice.

https://www.lenovo.com/in/en/faqs/pc-li ... s-full-hd/ - HD vs Full HD

I bought a Full-HD/1080p Philips 39" Flat-screen TV about 8 years ago. The price difference from a HD-Ready/720p TV was quite big. The Philips TV was quite heavy. Today's 39" Full-HD TVs are much lighter.

Visual discernability for the different screen resolutions depends a lot on the size of the display and viewing distance, when the source of the video is at the same screen resolution.

If you don't think you made a mistake and you are happy with what you purchased than that's all that really matter's.

I'm still watching an old 25 inch crt tv using an digital to analog converter box with an outdoor tv antenna and have zero complaints.

If you are happy with it then doesn't matter what anyone else thinks or says because they don't have to watch it if they don't want to.

But, see, it does actually when someone explicitly asks: boringly generic appeasement he had after all been able to think of himself without asking.

CRT TVs have a screen resolution of 480p, which may be optimum for 24" displays(25".?) and for 15" CRT monitors(= 600p) for computers(= 3 feet viewing distance).

CRT displays are electrical-power hogs compared to modern LED displays.

In my case, I mostly watch Live TV on my Android tablet = local and international free-to-air TV stations like BBC News, FOX News, etc.

480p? My Sony KD-30XS955 and KD-36XS955 SFP CRT TV does a bit better than that and still have better pictures than the Panny TC-P50ST30 plasma or anything this side of an OLED.

A TV is good for watching the news (such as it is) and not much else. I have no idea what resolution any of my TVs are and have never thought, "that picture is cr*p". None of them are newer than 5 years. The only time a Hi-Res TV is going to be an issue is if you are watching tennis or golf, where you need to see what happened.
