Just bought a TV (bargain - £75 delivered from Tesco for a 15'' HD ready LCD set) to put in the kitchen and my plan is to feed a cable from next door where the Sky+ box is into the new telly - I am not bothered about being able to watch different channels, just a second feed of what is on the main box.
I have a few questions - I know I have a choice of outputs (component, RGB, RF etc) from the Sky+ box (it's NOT a HD box) but which will give the best signal quality?
And the main TV is connected via HDMI - will I need to change any settings on the Sky+ box to allow for the second output or will it just be a case of plugging it in and selecting the channel on the new set?
RGB would give you the best quality but you'd probably need to make the cables up
just use the RF out
I wouldn't mind making cables up to be honest - but if the quality won't be much better it would be easiest (and cheapest I assume) to just co-ax it (and as the cable will be routed outside the house it will be easy to get weatherproof cabling).
An RF feed to the new TV would work best. Alothough Component or RGB may give a higher res picture (would you really benefit on a 15" screen)if you take a cable off the back of the sky box to your new tv you will get Freeveiw digital signal to it aswell, assuming you have an aerial plugged into the ky box. Also you can use a "Magic Eye" to change the sky box channels from your ne TV location. It reads the remote input, converts it to a signal that it feed into the sky box through the RF 2 connection.
The only change that might be needed if to cange the RF output of the sky box if there is interference but that easy enough.
I can't remember what sort of loss you get with RGB to make an estimate of what cable you'd need for a given length
Coax with the RF signal will be fine for very long lengths
assuming you have an aerial plugged into the ky box
No there is no aerial to the Sky box - we only have a dish. Otherwise I would have probably just run a cable straight from the aerial and get the benefit of Freeview (the set has it built-in). This is why I am happy just running the set as a slave to the main set next door.
Now all I need is the time to set it up...
Coax with the RF signal will be fine for very long lengths
I would approximate it as 35ft from source so no more than most home tv aerial set-ups I guess.
