1080 problem
 

When I set HDMI to 1080 rather than 720, things like the TeleWest menu look terrible - blurred etc. The HD programmes themselves dont look much different so Im assuming they are broadcast at 720? Is anyone else getting this problem? Any suggestions as to how I might get round this?

Re: 1080 problem
 

1) How is it connected?

2) To what TV is it connected?

3) :welcome: to the site. :)

Re: 1080 problem
 

telewest are only going to broadcast in 720p and 1080i on hi res. so by choosing 1080 your choosing the poorer signal,, your best going with 720 which is in progresive scan.

Re: 1080 problem
 

Please forgive an old audio hack for asking a basic question.

I thought in the bright shiny new digital world, that in the numbers game bigger is better.

I understand the difference between interlaced and progressive (though not sure why one should be better than the other)

But shouldn't 1080 be better than 720?

See, told you it was basic. Not doubting anyones word, but would like to understand.

Anyone willing to educate me, please?

Thanks

This was mentioned to me last night to and i had trouble believing it. I have my Xbox hooked upto my telly in 1080i but people tell me that 720p is better, i cant tell either way but which is supposed to be better?

Re: 1080 problem
 

If the broadcast is in 720 and 1080 is selected, then the picture has to be upscaled to the higher resolution. That kind of processing will always result in an inferior picture.

Re: 1080 problem
 

In other words, 1080 will only be superior with a broadcast at that resolution

Re: 1080 problem
 

So with regard to an Xbox 360 where you select 720p or 1080i as the output then 1080i is the better option then?

Re: 1080 problem
 

It depends on what resolution the game is at BlueRaja? I've not used a 360 myself so don't know what it looks like on a HD set, could it hurt to try?

Re: 1080 problem
 

I have done and i cant tell the difference to be honest. You specify in the console setup - not the game - what format you play in and i have tried both 720p and 1080i, both of which look great - but - like i say - hard to differentiate!

Re: 1080 problem
 

If 1080 doesnt cause any problems, leave it on that then? As long as the TV can support it then you should be ok

Re: 1080 problem
 

In all honesty though - that wasnt really my question but thanks for helping, what i wanted to know is which one is supposed to be the better format 720p or 1080i.

Re: 1080 problem
 

Right

720p uses Progressive Scanning, hence the "p" and therefor SHOULD be (but maybe not noticably) better than 1080i which uses old style Interlace Scanning. I get the feeling though that 1080 should be a higher resolution but maybe not as good quality for the Conneseuirs?

Re: 1080 problem
 

Thanks for trying mate, but here is a more techy answer i got elsewhere which seems to suggest as you say 1080i is not quite as good depending on the circumstances.

As with most things, it depends.

That's broadened my understanding of it Raja, have a greenie :)

this is the package i just purchased and connected my vm v+ under 1080 widescreen and theres a few problems ive noticed.
picture is blotchy, alot of the channels cant be made to fit the entire screen ive tryed every setting possible, sound is really poor and the v+ box freezes a glitches at the slightest thing, i transfered from sky where i only had digital not hd and the picture quality is really clear compared to vm v+ i spoke to tech department and they wont dropt my acc due to not been with them 12 months. now im seeing more problems i cant wait to look for another provider for my tv service.

Re: 1080 problem
 

The channels that "don't fit the entire screen"... are they HD channels? If so then that means the programme you are watching was filmed in 4:3. HDMI shows the channel in it's correct format, you can't stretch the image. This is not a fault.

If they are SD channels then you need to change the V+ to 1080i WIDE to stretch the pic on 4:3 SD channels.

Have you tried the 720p setting regarding "blotchy pic"? What channels are you getting a poor pic on? SD or HD?

Have you had a play around with the TV's settings? you need to configure your own tv for your preferences.


Also, well done for re-opening a 4 year old thread ;)

Re: 1080 problem
 

ive done everything to tweak the settings m8 virgin even offered a replaced box still blocks on the screen. they said it should settle as we just gone true narg3 and the stream is being worked on.
as the channel 4.3 thats just me being a freak lol its a pet hate with the screen size.
thanks for your message of encouragement m8

Re: 1080 problem
 

Hi

there isnt a fault with your tv or the box its a long well known issue on the sa boxes as i have a samsung v+ and the issue isnt present on the samsung v+ boxes on 1080i only on the sa boxes

I know what issue you are getting its only present on the epg menu like a fuzzing round the edges of the fonts on the screen.

just leave your setting on 720 wide

Re: 1080 problem
 

TAZMANUK i wish that was it m8 but following advice from falts department at vm i left the settings 12hrs on each 1080,720 and then both version but wideand the programs i recorded play back blotchy also and some tech guy said that if its a falt the problem would record if not then its not vm box playing up ive even connected my sons tv to the box under scart connection and its still same m8.
im no expert mind but i have to also point out the heatgenerated from the box within the 1st 5mins of being switched on is so bad ive attached my sone xbox fans to try to keep the box cool as thats when the disstotion really kicks in like an old 90's pirate movie haha.

Re: 1080 problem
 

1080i is higher definition BUT as it is interlaced, the moving picture or dynamic resolution is worse than 720p.

1080p would be ideal but would take twice the bandwidth of both 720p and 1080i. 720p and 1080i have almost exactly the same bandwidth but as 1080 is the bigger number, most broadcasters use it.
AFAIK all VM HD and SKY HD transmisions are 1080i. BluRay is 1080p.

Re: 1080 problem
