Is there a way of determining best height for a (bedroom) wall mount telly, or do you just take a stab? It's hard to tell where it should go at the moment as there's no finished floor, walls or ceiling, but we need to tell the builders where to put the sockets for power etc.

Presumably, you're planning on hiding the sockets behind the TV?

Is the TV going to be fitted flat on (or into) the wall, or on a mount? If you use a wall mount, they're usually adjustable for pitch, which gives you some freedom with regard to height.

Flat onto the wall. I didn't realise brackets allowed height adjustment. OK will order a bracket and see what it does. Thanks

Brackets allow tilt adjustment, not height adjustment, but the point is that you can have your telly high up and tilted down a bit, or lower down and not tilted down so much, i.e. the availability of tilt adjustment means that the height isn't critical.

The thing you're wanting to avoid, at least for LCD TV, is looking at a TV from below its centre-line. Lots of LCDs have a good viewing angle left, right, and up of centre, but not down.

I have a slim TV Bracket that allows about 12 inch of height adjustment. Not much but it works pretty well.

Any idea which one it was Cris? Can't see any that are adjustable for height

I got it about 18 months ago, cheapo eBay jobby, was about £20 and was advertised as an Ultra Slim model. There is very little tilt adjustment on it.

I didn't buy because it was height adjustable, it just turned out it was.

This is in a bedroom, so I assume this will be something you want to watch from a bed? In that case I guess it would be higher than in a living room.

I don't know a specific height, but I suppose this would be the only case in which I'd be okay with a TV mounted as high as those who put them over a fireplace. Otherwise I don't really understand that. It's too high!

Not for a bedroom.

In the living room I'd aim for my eye line to be in the middle third of the screen. In the bedroom you may want it a bit higher and tilted down since you'll be lying back on the bed.

Edit: tahir: you probably already have the bedroom furniture. You should be able to work out a height from that shouldn't you? If the room is significantly longer/wider then factor in the angle.

The plug only has to be behind the set, not exactly in the middle.
Unless its a truly small panel there is a lot of leeway.

For instance I'm looking at a 50" plasma that is 30" tall.
So a plug at 50" would be hidden:
If the set was 22" below an 8' ceiling.
If the set was 26" above the floor.
(Assumes plug center is six inches above or below tv's edge.)

No furniture at all. The only thing that'll be coming over from the old house is the sofas

But not all. Our Samsung LE32R41BD has a superb viewing angle in all directions, including down.

Recessed recepticals there are many different ones. Basically they allow plugs, space to reside below the surface of the wall. Some are more difficult to use than others. Theoretically the tv can be closer to the wall.

One of the many

Every single one in those search results, though, is for US plugs. There's a reason for that; in fact, there're two. In

Or if it is a modern new build it could be cavity walls and plasterboard which is very easy to work with. Anyway, just wanted to add that in case bulk is a problem you can use MK 995 Clock Connection Unit for TVs on the wall. It is a recessed socket which is completely flush when the square plug is inserted. You do have to cut the plug off the TV and wire into the plug on the MK 995. Rated at 2A, so it is suitable for TVs up to 460W. Its a neat solution in case this kind of thing is ever an issue.

It's actually a new build (like a still in construction new build) timber frame, there are 50mm battens fixed to the structural walls to allow a service void before the plasterboard goes on. Theoretically around 65mm of mounting depth

It is indeed quite neat. Have bought a bracket will test mount it at the weekend to see whether I need something like this. Thanks

No surprise there, given that we don't use the term receptacle for that item or indeed really have the concept of a recessed version wink

We just don't need them as we have sanely designed mains plugs...

How can any electrical plug the size of a baseball cricket ball be considered sanely designed?

Yeah. It's a very intelligent design from a safety perspective. But I've often wondered what effect the huge clunkiness of it may have had on techno progress in the UK. smile

Having used 240V power plugs in other countries, the UK one is pretty solidly designed for it's use. The Australian power plugs are abysmal, they are basically US pins rotated to 45 degrees. Accidentally jiggle the cable and you get a pretty light show of sparks!

Sounds like fun. Other power plugs/sockets always seem inadequate when you're used to a a UK switched socket/fused plug.

Which, of course, is designed that way because the circuits are allowed to run much higher current than the outlet, whereas everywhere else in the world, the limit is on the circuit. (Ring topology vs. star topology)

I don't ever see sparks in Australia with any reasonable quality power point (aside from significant inrush current on Dell power supplies that cause sparking/scoring on the plug).

Asia is where you see crappy power points, particularly those multi sockets. I don't think I've ever found a powerpoint in India that works well.
