Thread: Awful picture on SD channels?

  1. #1

    Awful picture on SD channels?

    Not sure what the reason for this is, I have tried changing from 720p, 1080i,1080p 50hz/60hz and multi and nothing makes a difference. On SD everything is jagged and blocky. Its clearly the box at fault as never had this issue with my old Zgemma. Any idea how to fix this or is something faulty.

    Use webif and post better pictures so we can get a better picture of your problems. You can't automatically assume the box is at fault. Have you tried a different HDMI cable? Have you tried the box on a different TV? Have you reflashed your box with the latest ViX 4.1-009 image and setup as new with no restores? Have you setup the A/V settings correctly? Numerous possibilities.......

    It was a brand new box yesterday from WOS, setup using the latest Vix Image. It doesn't actually look to bad on screenshot but is on the TV. The HDMI cable is the same I've been using for years, works fine on other boxes. As for other settings I've been through 720p,1080i,1080p and tried 50/60/multi, I can't see any difference. It could be the TV yes but the fact is the TV works fine on other boxes.

    Compare the top right of screen shot with the top right of the photo I took, there is almost ghosting coming into play which doesn't show on screen shot. This leads me to believe something to do with HDMI port.

    Try a diiferent (new cable). Even I have blamed a new receiver in the past until I took it to a neighbour and proved it was another component in the loop
    Obvious is often wrong


    Also whats the HD picture like?

    HD Picture its just not right either, yes its clear etc but it almost goes to far and its getting slight ghosting. Could well be the cable, I will purchase a new lead when out and about today and see how I get on.

    Sounds like settings on your TV might need adjusting.

    webif ist not suitable... because the raw video data are just converted to jpeg. what goes out thru hdmi may be totally different.

    Right guys changed lead an no difference. The odd thing here is on the like of menu items / epg etc its crisp and clear, its only on actual TV channels. SD channels are awful, like watching youtube in 360p

    What model TV do you have (I am assuming there is nothing between receiver and TV?) and do you only have 1 hdmi input?
    If more than one try one of the others ....
    Also paste a picture of your setup/AV settings display

    Hi, I have a 43" Philips 43PUT4900, It has 3 HDMI ports and I have tried them all. The receiver is connected direct to TV, Nothing in between. Its something to do with SD up scaling I think and I see another thread on here about that which went no where.

    Agree with the multi .... sounds really stupid but I always use it ( ) and it has seemed to solve issues in the past
    Also letter box.

    Perhaps try auto resolution instead of forcing 1080i
