    I believe the HD means High Definition... would explain the better picture...

    The display is 720 pixels across, which is the lowest HD definition. The better one is something like 1080. Note how poor they are compared to your computer monitor.

    We've got a 720, it's perfectly adequate.

    Thanks for your help (and jj)


    I understand what you are saying---but---the picture was breaking up and often going completely, not just less sharp. I see 1080 as an option, so should we try to get that ? ! ? !
    We were happy with 405 lines, so not obsessed with 'good' picture quality !!:Sad::Smile:

    Generally speaking there are four modes of HD TV picture, these are in order lowest quality to highest:

    720i, 720p, 1080i, 1080p.

    The "i" stands for interlaced and means that the horizontal lines of the picture are scanned in an interlaced fashion so lines 1,3,5,7,9 etc first then the even Nos.

    The "p" stands for progressive scan and means that the horizontal lines are scanned 1,2,3,4,5,6,7 etc.

    In interlaced mode you get every other line of the picture scanned 25 times a second, in progressive you get the whole picture scanned 50 times a second which sounds like the same thing but progressive is better.

    You may well find that the picture quality is better when using a HDMI connection to your set top box or sat receiver even when viewing a non HD channel, our TV gives a marked improvement using the HD connection than Scart.

    We have a full HD TV, and a Blueray DVD. Even "ordinary" DVD's are of a better quality. 1080p rocks:Smile:

    Start from the beginning.

    You have a TV - do you have the spec or model number of that.

    Then what are you trying to view - DVD or Freeview or Freesat.

    Then what is the cable connecting the two, normal big rectangular SCART or the newer thin HDMI with flat cable.

    Take it easy on me---this is all foreign to me !!!:Doh:
    Yes we have a TV (that one was easy)----it's a big Toshiba digital--it's fixed to the wall so I can't see any info on the back----It' a US set with a freeview digi-box that takes the UK signal and makes it suit the TV-- The cable is HDMI plus there is a red and a white plug (I can see these in the back of the digi-box) With a mirror, I can see these going into the back of the TV (I think)

    I am sure we have a book on the TV-----Just need to find it:Doh:

    I would have thought that if your pictures / channels are breaking up and going, then that will be a reception issue, and nothing to do with HD resolutions.
    Going to a higher resolution will not be able to help the with reception issues.
