@jwacalex probably, I briefly mentioned them but have zero experience actually working with them. I've never seen them used in a mobile setup

Thanks for the thorough answer. What about renting a solution? Either renting the projector or the proj and screen?

@AJHenderson i only have seen them in semi-permanent setups for booths on tradefairs or a greater events e.g.  at [wacken open air](http://www.wacken.com/index.php?eID=tx_cms_showpic&file=uploads%2Fpics%2F0_wackenwall.jpg&md5=1fe9285f67e279e66f67b10c42e96388f5d133e3&parameters[0]=YTo0OntzOjU6IndpZHRoIjtzOjQ6IjgwMG0iO3M6NjoiaGVpZ2h0IjtzOjQ6IjYw&parameters[1]=MG0iO3M6NzoiYm9keVRhZyI7czoyNDoiPGJvZHkgYmdDb2xvcj0iIzAwMDAwMCI%2B&parameters[2]=IjtzOjQ6IndyYXAiO3M6Mzc6IjxhIGhyZWY9ImphdmFzY3JpcHQ6Y2xvc2UoKTsi&parameters[3]=PiB8IDwvYT4iO30%3D) which was build by [leurocom](http://www.leuro.com/)

They are actually pretty great for these things. We use them all the time for huge displays on fairs.
We also worked with leurocom, they do pretty amazing stuff with LEDs.

<p>"Most affordable" makes this a very difficult question to answer. The way most festivals do it is by hiring large screens. You could try and do it with a projector, which can work okay at night, but not so good in daylight (like a drive-in cinema). </p>

<p>For bright displays there aren't really any shortcuts - </p>

<ul>
<li>Have a good video platform and desk</li>
<li>Route signal</li>
<li>Use good quality screens</li>
</ul>

<p>Technology-wise, it is very simple, as you aren't doing anything clever with video.</p>

Renting will depend on your locale etc. Either google for local companies, or ask an organiser of a festival that uses them in your region.

<p>My company produces some out door concerts that will have 15-18k people attend. I'd like to setup a video screen next to the stage that I can use to show a video feed of the concert. I don't have a lot to spend on it, but I would be reusing it for other things, so what do you think? I have a switcher that does hdmi and hd-sdi output, so a projector or system would need to use that. </p>

<p>I'm trying to create something, similar to the picture attached. <img src="https://i.sstatic.net/zkt4d.png" alt="Video screen from A7X at Rock am Ring"></p>

Size plays a major role in the price. So a rough size estimate of what you need would be helpful to give you an answer.
Rock am Ring has one the largest stages in the world, I'm sure you are not going for exactly the same thing.
A rough estimate of your budget would also help greatly.

There isn't an "affordable" option here. Either you use high intensity light screens or high intensity rear projection with an enclosure around the back side to keep out sunlight. Either option is looking at tens of thousands of dollars per screen to buy.

I'm not particularly familiar with light screens because they tend to be a lot harder to move than the rear projection units, though if resolution isn't super critical, there are hanging displays that use basically strands of Christmas tree lights as pixels that are pretty portable.

For rear projection, you are probably going to want something in the neighborhood of 15 to 30,000 lumens per screen which is around $30,000 to $60,000 worth of projector, plus the cost of the screen itself which is likely to be several grand as well and also the (relatively speaking cheap) box around it all to block out light from hitting the screen from behind.
