Outdoor projector
« on: February 20, 2018, 10:53:20 pm »

We did a cooking event last year with 50" or so video panels if full sunlight showing a live video feed.  It definitely was not bright enough and impossible to reduce reflections.
It will happen again this year, so...
I was wondering if projecting onto a cloth type screen would work better in this situation (no reflections).
How much power would be required?  I know this can't be answered without a distance (don't have it).
How does front projection compare to rear projection?  I imagine it isn't as bright, but easier to setup.

The only direct view in full sunlight capability that I am aware of for video would be LED video walls.  Projection cannot compete with the sun.

Projection can't even compete with your 50" screens for brightness. Outdoor daylight requires LED screens and they are big money and big labor.

Yep.  The cheap stuff is close to $1000/sq ft when you're all said and done.

Can't you put the screens in the back of a black party tent? Cheap and effective.

Not effective unless the audience is under the tent, too.  Everyone's eyes will be adjusted for daylight - the screen as you describe will still be illegible.

Probably the biggest problem with the video screens is that we could not get them free of reflections.  Tilted up or down, they still had issues.

Can you provide us the make & model of “video screen” that you were using; I can’t recall the last time I noticed any reflection off of a proper LED wall.

They were not LED walls, they were 50" TV monitors.

50" CRT monitors?  Can't be.

Were they 50" video cubes like Toshiba or Clarity?  Toshiba used CRT engines.  Clarity used projector engines.  4:3 aspect ratio?
