I’ve just had a V6 installed which works really well with my Sony UHD TV with superb picture quality. I had in mind to use a splitter so we could watch the TV in the kitchen. But before I set this up I checked to see if the V6 box works. I connected the V6 directly to the other TV via a new HDMI lead but it shows ‘no signal’ . I tried with another TV in the bedroom and this was the same! The kitchen TV is about 10 years old and HD 720p, the bedroom TV is HD 1080p. I know the HDMI ports are OK because my PS4 and the DVD player connects fine with both. Is the output of the V6 box too much for these sets?
