Update: Got hudl replaced (fresh one from the factory apparently) and I now have no issues with any TV's and/or HDMI cables. So it was hardware related. Although they still need to release a software update for true 1080p output*
I too would like to know if anyone has had any luck with this and if it's true 1080p display with no vertical black bars on either side. I might go into tescos store and ask them to test it on one of their wireless ready TV's, as the HDMI is useless at the minute.
I have tried three different HDMI cables of different sizes (5m, 3m, 1m). The 1m works well in most resolutions on my 32" samsung tv. I have a smaller HD Ready tv and when I plug the hudl into it, the screen flickers blue literally every 10 seconds with any of the cables. I know it's not the cable or tv, as it works fine with other HDMI peripherals I have.
According to tesco it's software related and they will be releasing an update to fix this issue which they said is coming sometime in February, so I'm holding onto the hudl till then because everything else I am happy with but really could do with the HDMI working better.
Issue 2. Aspect ratio/Vertical black bars on TV Display
They really need to fix the black bars on either side of the tv screen. I've read it's a problem with all tablets running 4.2.2 and google aren't fixing it. Am yet to find a workaround other than using a lower resolution and zooming in, as stoolzo recommends. It's a real shame because the hudl is advertised has having "1080p HDMI output" and it's nothing like it as it just mirrors the display as small as you see it on the hudl itself and you have to use the zoom feature to make it bigger (and even then it doesn't fill up the tv screen). I am yet to find a workaround for the aspect ratio in a higher resolution and hope the software update in February addresses it.
Great thread. I need to root my hudl because I want to install an app that needs root for turning the display off when connected to a tv. I take it the rom will be be updated when tesco update their software? I'm waiting on two updates they said are coming out (the first to fix the touchscreen issue, and secondly the HDMI connection issue).
I rang the helpdesk and they informed me that the touchscreen becoming unresponsive is software related and a fix via an update is coming out before the end of this month. I am waiting for this and an update for an HDMI problem (also software related) due for middle of February, to fix my Hudl. If it doesn't I will return it.
