Flickering white spots

Hi, I had my V6 boxes installed yesterday.  One is connected directly to my TV, the other via room extender so goes into an HDMI splitter, then into an extender via CAT7.  This process works fine for all my other outputs (Apple TV box, BT Vision box, DVD player) but with the V6 it has flickering white spots and keeps cutting in and out.

It is not the box as we tried both boxes directly into a TV and they are fine. 

It is strange as when you reboot the box, during the initial startup with the welcome in various languages it is all crystal clear, so only once the standard virgin screen comes up.

Does anyone have any ideas?

Re: Flickering white spots

Try a different HDMI cable

Going through a splitter is not a good idea

Re: Flickering white spots

flickering white spots is a sign that the HDMI cable doesn't have enough bandwidth

Re: Flickering white spots

thanks does the virgin box take up more bandwidth than say an apple tv box? The virgin box is set up to output at 1080

Re: Flickering white spots

I read here that some people who swapped a tivo for a V6 had the issue so it uses more bandwidth than the tivo, don't know about the apple, just get a £5 amazon lead it should be fine

Re: Flickering white spots

Hi

As an update Virgin came round and said as it is nothing to do with their box they have fulfilled their obligation and could give no more help.  I would have thought they would have had some ideas given I cannot be the first. 

per the V6 specs it says 1 x HDMI v2.0a output with HDCP 2.2 copy protection and per the PU-1103TX/RX it says compliant with HDMI 1.3, HDCP 1.1 and DVI1.1 standards. (http://www.farnell.com/datasheets/815454.pdf) - is this the reason for the issue?

Thanks to all for help

Re: Flickering white spots

 

Have you thought that the HDMI splitter may not be up to the job ?

Re: Flickering white spots

do you mean the extenders the PU 1103TX/RX? as that is all that is left, as it goes V6 => HMDI 2.0 cable => PU 1103TX => cat7 cable => PU 1103RX => HDMI2.0 cable to LG 4k TV which handles both 4K and 1080

Re: Flickering white spots

Why not run a long HDMI cable instead of all the converting ?
