  1. stoolzo added a post in a topic HDMI cable?   

    cable quality only comes into play over 5 meters when resistance starts to become an issue, even then it wont degrade your picture it will likely still work but become more unstable, i.e mine which turn off and on at the slightest power surge to kettle, fridge etc. I replaced it with a cheap 1.99 cable which was under 5 metres and I no longer had any problems.
     
    There will never ever be any discoloration which different models of HDMI cables, never, nada, none, is'nt going to happen, as the chap above says, its 1's and 0's, light doesn't even come into it. Any cable under 5 meters that costs more than £5 is a rip off plain and simple.

    not too stressed either and also wont be returning it as I bought it for my mum for XMAS, just disapointed more than anything. Yeah, this is more a google problem than tesco, however they should have done their homework properly and brought out a table with the correct aspect ratio.

    final correspondence from tesco "techical" with my reply.
     
    Dear xxxx,

    We have had this issue investigated and the Hudl is working as it was designed to do by mirroring the display from the Hudl on the TV when connected via HDMI.

    As the aspect ratio of the two devices is different, unless this is altered by stretching the image via the TV, you will always have black bars or parts of the picture missing.

    I acknowledge your suggestion that the movie app is supposed to ignore the aspect ratio of the Hudl, but the TV is mirroring the display of the Hudl, so it will not do this.

    Once again I will reiterate that this is how the unit was designed to work and we will not be changing anything in any future updates.

    If there is anything else I can help you with, please do not hesitate to contact me.

    Kind regards

    So you've designed a tablet with an aspect ratio which will not properly fit any television screen in the known world on purpose - the sole purpose of a HDMI output - pure genius.

    "I ran TV Catchup, 4OD and iPlayer and it displays with black bars top & bottom whether I use Full Screen"
     
    Ok, here is the issue for me, if you get black bars both top and bottom when viewing apps like 4OD, iplayer etc then it means you have got the HUDL set differenty to everyone else. When setup correctly the home screen and normal apps should show bars only at the sides, the top should meet as should the bottom. This is because in home screen and normal apps the HDMI outputs to your TV with the same aspect ratio of the tablets home screen, this is why its called mirroring.
     
    Go into settings, hdmi and have a look at your resolution, is it set to 1080p 50hz, 1080p 60hz, or one of the others, perhaps 720x480?

    workaround for black bars.
     
    Workaround (some tv's only)
     
    1. Set the hudl hdmi to 720x480 x60 hz (60 hz as most films will sync to this frame rate better than 50hz
    2. in the same HDMI settings zoom until the picture to the right until you blacks have gone.
    3. Install BS player free, awesome app, it can hardware decode just about anything these days, just remember to turn hardware decode in settings.
    4. Load the movie, you should now see that it should touch both edges but will be stretched slightly on the horizontal plane. 
    5. My tv has various picture sizing options, one allows you to increase the vertical height, set this to put the picture back in its correct aspect ratio.
     
    This pretty much give you a decent 720p output, we would do this with the 1080p option of there was a little more room on the zoom option, although TESCO / GOOGLE really need to fix this bug,

    i have an acceptable workaround but it takes a bit of fiddling - note however i still believe there is no way watsoever to remove the side bars while you have the hudl set to 1080 output.

    " I don't adjust anything either on the Hudl or the TV, just connect via HDMI"
    What happened to the above Greyrider? so we've gone from doing nothing but plugging it in to rooting the device and installing the full screen app?, and then changing aspect ratio on your TV, thats at least three things you have done. 
     
    I think you need to explain exactly what you've done here as you have clearly fiddled about and not just plugged it in. you also haven't told us which aspect ratio your TV is in.

    if you are playing a TV episode which is in 16:9 (normally completely fills the screen), before you do anything in VLC is there are black border at the sides and the top / bottom?

    sorry but this sounds dubious to me, the black borders left and right are pixels that the HUDL isnt outputting, there is no way to extend any app into this area by zooming as this area doesn't exist as such.  This is known bug with Android 2.2 - there is no way around it without rooting and hacking.
     
    The only way to extend the picture left and right would be to zoom your TV, if you do this you lose the bars but the picture is then stretched horizontally which is worse that having black bars. 
     
    If however you have got this working by dropping into 720x840 res on the HUDL and farted about with your TV zoom and aspect ratio to get something like roughly looks the part - I have already done this and it looks shite. Nothing less than full 16:9 1080x1920 output is required to get a properly picture here.

    Bad news, this looks like a pretty standard problem with tablets without a standard Tv aspect ratio - see this:
     
    https://code.google.com/p/android/issues/detail?id=40225
    would really love to know how those people who claim to have this working out of the box did it, do they have 16:10 aspect ratio TV's?

    hi, just so we are clear here, i'm not trying to get the launcher to show in full screen, just movies. I'm pretty sure that when playing a movie through the video player it should default to a standard TV aspect ratio but it doesn't, it keeps the aspect ratio of the main home screen, this appears to be the problem.

    tesco replied, the issue has been escalated to their second line, good service so far from them.

    i logged a call with tesco support, quite suprised I got a good techy answer even if it isnt quite what we are after:  
     
    Thank you for your mail regarding the display on your TV screen.

    The resolution of the Hudl is 1440 x 900 pixels, and your TV screen is 1920 x 1080 pixels. These two displays have different aspect ratios, meaning that the ratio between the width and the height of these two images are not the same size.

    The output from the Hudl will be stretched until it meets the limiting dimension of the external display. When you increase the height of the image from the Hudl until it is 1080 pixels high, to keep the same aspect ratio of the image, the width of the image only become 1728 pixels wide. This results in a difference of 192 pixels which is then split between the two sides of the image that will create 2 black areas of 96 pixels wide each.

    If the image was stretched from 1440 x 900 directly to 1920 x 1080, it would result in the image looking as though it had been pulled width ways to fill the screen and the image would look incorrect.

    If there is anything else I can help you with, please do not hesitate to contact me.

    Kind regards

    I have replied back suggesting that the video player software is supposed to output a full 1080p image irrespective of the resolution of the tablet screen which is what my galaxy S3 and Glaaxy note 10.1 does. ( i bought the HUDL for my mum for xmas)
     
    This also suggest that those who claim to have this working properly  must be zooming the image somehow and are not watching the movie in the correct aspect ratio to get it to  fit the screen. I can drop mine to 740x480 and have it looking about right but the image is low res and fugly.

    I cant see this being an issue with our TV's, i'm starting to think those that say its working ok are somehow mistaken in some way or they have an extra option on their TV which zooms the picture, however this would mean that the top notification bar would be missing when they close the movie and went back to the android home screen.

    Hi, are you using the tesco HDMI or did you buy a cheapo like me, what firmware version are you on?. Those that have this working, can you report where you got your HDMI cable from, which version of firmware you are on and you HDMI settings in android, cheers.
