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?

Did you read the thread. 50" flatscreen LED TV monitors. Not a video wall. Not an LED panel video wall, not a matrix video wall of monitors. He is asking about alternatives that don't have the reflections on these monitors.

Maybe just hang a big mirror over the cooking space at 45 degrees. ::)

See if you can rent some Sunbrite TV's. We install them in direct-sun applications for patio bars and they work quite well with sun hitting them directly.
Other than that, direct-view LED is what you would use. In the old days I remember building large horn-shaped pipe&drape tunnel structures and doing rear-projection. (Projector at "throat" audience at "mouth" and screen about halfway between the two.)

video wall or bust...... to buy very expensive, to rent still very expensive. The more detail you want the more expensive it becomes. Outdoor in 6mm - 10mm will cost about $100 per square ft to rent with rigging and labor!!!! If you want 3mm - 4mm add some more $$$
It's typical for standard size LED walls to go for around $10k to rent after labor and rigging is factored in. A standard size wall is roughly 9' X 16" or 144 sq. ft. This is typical for 4-6mm LED walls. As you start getting to 4mm and below the price starts going up DRASTICALLY. Newer 1.5-2mm walls are selling new for close to 5K per panel ( 1.5sq. ft. ). You can imagine the cost of rental also goes up with it.
You need to know your audience distance. Most walls are rated for optimal viewing distance, or basically the distance in which the pixels are no longer viewable and you can see the whole panel as being one image. For sub 2mm walls this distance is roughly 10-15' whereas 4mm-10mm walls require as much 30-90' or so.

Just your regular 50" flat panel video LCD screen. Like the one in your living room. The promoter rented them. I'm just investigating something that would work better.
