40" screen and viewing distance

We're building a new studio and the consultants have spec'd out a 40" screen for the multi-output from the mixer.I've not seen the list but it will display the sources and outputs

They then say that the viewing distance is at least 2m. That's all very well, but we will need to do big mods to the gallery design in order to accomodate that. I'd have said that something approaching 1M was more realistic.

They want the desk in the centre of the room, which would mean designing a cantilevered gallery, but the main design work has already been done. The Gallery as it stands is only 2.5M wide/deep which is tight, but enough for a flat screen on a wall, desk, operators and enough room to walk behind them. It's 5M long

Isn't 2M a little excessive? I assume that they know what they're doing, but they don't have to negotiate a re-design with a building that's near the starting stage.

I'd have thought that a smaller monitor a bit closer would be fine.

Hi Dave,
Probably can't add more than you know, but I'm having trouble visualising.
Are we talking about a windowed gallery overlooking a live studio, or simply 1 edit suite/room?
With talk of cantilevered gallery, I assume ceiling is higher than average?
May be very stuffy with head at ceiling height in summer with all the computers, no doubt consultants have covered that.

If you can link in a pdf plan, that may convey better.

Purely from experience in home viewing telly land, 40" 2m for SD sounds about right (or possibly 2.5M?).
Perhaps its a Hi res screen with multiple sources (inc. outputs) being simultaneously displayed from mixer to split screen(s), so viewing distance will therefore be reduced?

assuming its a multiout preview like the Panasonic AV-HS400 then 2m is a bit big IMHO
assuming its going to display PVW + TX + 6 Inputs then the preview and program monitors will be aprox 19" and the channel previews will be 9".

I prefer to have all the monitors within my vision without having to move my head round to see them all - if you go under a meter with this monitor system it will be too big and the vision mixer will get annoyed by having to move his head to look at the different screens. Conversely at 2meters 9" is quite small for a input monitor and anyone with less than perfect vision will have trouble viewing the content at that size.

I wonder if your consultant has ever done any vision mixing?

yes

It's a single 40" with 8 sources, preview and output (I'd assume) The computers should be in a separate machine room so heat and noise isn't an issue. The output will connect to an EditShare in an IT server room

It's a gallery 5 x 2.5 with all the kit on the rear wall, facing away from the studio. Behind the seated crew, we will have a floor to ceiling window looking down on the studio floor. the window will be at an angle so you can see right down to below the window.

The problem is, the disability rules say that we have to have access so a small staircase is out. The studio is double height at about 25feet and entry to the gallery is via a spiral staircase from the studio on one side and level with the rest of the building on the other (hence the need to walk behind the crew) This means that the gallery is higher than it needs be, in order to line up with the rest of the floors and lifts.

the current gallery has 14" monitors and the edge of the desk is 30" from the glass of the mons. The vision side is about 5 feet wide.

Hi Dave,
I believe I have a clear image of set up now.

How about, desks facing stage, walkway behind ( by back wall) and screen 40" or bigger suspended outside gallery close to ceiling, assuming lighting rigs ain't in the way.

Downnside - will mean part of floor level window will be obscured.
Upside - 'Live' studio visible to crew, possibly making camera direction easier?

If its a good idea, my consultancy fee would be $$$.
But FOC to you. ;)

Hi Dave,

That doesn't work as once all the kit is piled up infront of the glass, you can't see the floor. We'd use all of the floorspace and need to look directly down. The glass is triple glazed and vewing through that'd be a nightmare.

we need the walkway near the glass as the doors to the stairs are there, and mounting the kit on the solid wall allows speaker placement for sound and the lighting desk. (all operations in the one room)

I suspected they may be fly in the ointment to Baldricks cunning plan.
I thought about the light /visibility behind glass, but guessed it would be OK as its a bright source to presumably lowish lit gallery, though anticpated cabling problems.
As desks are 'centre' not full gallery width I thought that may leave sufficient floor view area.
I'll stick to the turnips.

I think the first question I would ask is how many people will be watching the monitor..... the closer the monitor is, the more acute the viewing angle for people at the sides....?

Just my 2penn'orth...

I'd say only two people watching the main monitor. If weiving angles became a problem, I'd suggest more monitors either mirroring the main one, or just showing the output for lighting and sound.

Either way, it's far less expensive to buy three 32? inch monitors than modify the design of a steel framed building with acoustic walls and floors

It sounds as if you've got options, I guess you will have to find out why the consultants wanted 2m. in the first place...
