Full HD and Blu-ray

JeffG1 · 11-01-2011, 16:19

Until a couple of days ago, I thought that a Full HD set was the same as HD ready, but with an HD Freeview tuner built in.

Am I right now in believing that the difference is that a Full HD set can display 1080p whereas HD ready means 1080i at best?

Can my BD player not operate to its full potential with my HD ready Sony TV, and is there a marked difference?

A full HD set will display 1920x1080 pixels, the i or p are not relevant with regard to the display only what inputs it will accept.

Your HD ready TV may or may not have this resolution (it can be both HD ready and full HD) though since it's a Sony it may well be better than one that is full HD anyway. Depending on the distance you sit from the screen being full HD may make no difference.

What is your TV model?

JeffG1 · 11-01-2011, 16:35

TV is KDL-32U30xx
BD is BDV-E370

The TV manual says supported formats are 1080i, 720p, 576p, 576i, 480p, 480i.

So no 1080p

I've got two Samsung TVs, one of which I can't feed 1080p to because I'm using an AV amp that doesn't pass it through. Buggered if I can notice any difference between 1080i and 1080p.

That's good to know. I had visions of missing out on even better picture quality.

Just to be clear, keefy-boy makes no mention of the resolution of his TV.
He says he can't notice any difference between 1080i and 1080p, but his TV probably has 1080 lines of vertical resolution, so he is just comparing the difference between progressive (p) and interlaced (i) transmissions.

Your TV on the other hand has only 768 lines of vertical resolution, so when you watch a 1080i transmission on it the TV has to downscale that to 768.

Having said that, unless you are watching your 32" set from very close, you probably wouldn't notice the difference.

So no 1080p

Set it to 1080i on the BD, it will look perfectly fine - you can always try 720P and see if you prefer that.

JeffG1 · 11-01-2011, 20:40

Thanks for the tips/info. Not having played with the BD settings, it's probably set to [Auto] for the HDMI resolution. I'll have to check that and play around with it to see what's best.

Since the BD system appears to control the TV through the HDMI cable (the TV sound is automatically muted when BD system comes out of standby) there is probably some sort of handshaking going on anyway.

It's called CEC - developed by Sony and Panasonic.

There is an option on the TV to disable it if you want - which you often have to do for Sky HD, as the HD box sometimes upsets the CEC.

1080i can be 1080p. Assuming it is 1080 native, everything must be deinterlaced to display, nothing is acutally displayed on a flat panel interlaced like on crt. The only question is how well the set will deinterlace 1080i into 1080p. 1080p film materall sent as 1080i generally can be deinterlaced without much loss for display. Older displays might have less motion resolution and other nonsense though...so who knows, but in any case I wouldn't worry about it. 32" is a small screen, the extra resolution of bluray will be more than enough even if it doesn't deinterlace it perfectly, the screen is so small that 1080p viewing distance is essentially computer monitor distance, in other words, you won't see much of the 1080p detail back at 6-8 feet, the screen is simply too small.

AFAIK, your panel is 1366x768 resolution.
"Full HD" is 1920x1080 resolution, as provided by Bluray or Sky HD TV channels.

With a 32" TV at normal viewing distances, you won't be able to tell much difference. But if you got closer or had a bigger display, then compared with a Full HD display you would see increased levels of detail on the Full HD set.

JeffG1 · 13-01-2011, 12:21

Thanks for all the help and info! Actually, I am quite amused at 32" being described as "so small"

It's the largest TV I have ever had and anything bigger just wouldn't fit in my small living room.

You must live in a shoebox then

32 inch sets are really considered pretty small now, and the slimness of LCD's means you can easily fit much larger sets in than before.

For HD viewing, 32" is small unless you are sitting very close to the set. The "ideal" distance is quoted here as 3.6 ft

You would need to view from a maximum distance of about 5 ft to get much real benefit from HD.

My lounge is quite small and I watch a 50" TV from about 10 ft.

Even that is a compromise, where HD is noticeably better and SD is still acceptable.

Well it is now

Sure back in the day when things cost way way more it was big for what you could afford, but it wasn't big as a matter of visual size or optimal nature for home cinema or even tv viewing. 2.35 image on that is simply 12 inches tall, a tiny stripe on the wall of an image, even a painting is not that small

Prices have been dropping big time, and so now the size of tv is finally getting hwere people can buy the right size, rather than the only size they can afford. Back 6-8 feet and you need far larger than a 32". As for your room, since these things take up so little volume in space, esp when wall mounted, easily bigger can be accomodated unless you are bent on using old crt cabinet furniture.

JeffG1 · 14-01-2011, 12:13

My setup in the corner of the room. Looking at it, I guess I have room for a bit larger screen

loz · 14-01-2011, 12:22

Our 50" set up seems quite small now.
Even the wife thinks a 65" would be a good idea!

That looks like the perfect location for a projector screen. How about 100" ?

Mine looks identical and was very good value. It happily supports a Pioneer-8G 50" plasma.

Sky HD is 1080i, all broadcast High Definition TV in the UK is 1080i. The only source of true 1080p is BluRay.

But I didn't say it wasn't... I never mentioned p or i

However, remember Sky movies (and other programmes) are broadcast as 1080/50i, so the TV can reconstruct 1080/25p. You might be hard pushed to see the difference between Sky HD and Bluray resolution wise. But of course the bitrate is much lower, so they PQ still isn't as good as bluray.
