Hello, I had previously posted here to get help with rear projection for a project and the mod suggested valuable information which helped a lot.
However, eventually I was suggested against it, for the project. So I've decided to go with outdoor LED screen.

Working time: Morning to Night
Screen size: 9m width*2m height
Distance from ground to screen bottom: 8m
Distance from screen to target audience: about 25-40m (to 80-100m)


So far, we've ruled out P5 and P6 for the low distance reach. I was suggested P8 or P10 for the good reach and cost as well. I could go higher but concerned with the screen's relative height to width ratio and mainly, the screen area size of 18 sqm - for the overall clarity.

Would P10 be perfect or should I go lower or higher for the said reach with a moderately good image clarity and cost? Or, what is the maximum view distance I can reach for 9*2m with good image quality?

So, this was a good read...
https://www.eagerled.com/new/How-to-choose-Pixel-pitch-for-Outdoor-LED-Sign.html

I would say that their claim of size in square meters determining pixel pitch (resolution) is bogus.

Resolution and viewing distance is what maters most. How far away from the image will you be at what resolution to get the most out of the image. Which, they do cover.
They suggest that with a 30m+ viewing distance that a 10mm pixel pitch (P10) is appropriate.

If you are closer than that and demand the best possible image, then P8 may be better.

From there, brightness shouldn't be an issue at either size as both are very much daytime viewable. This is the same type of technology used in Times Square NY and many other downtown locations. It's what is used at all the outdoor stadiums as well.

My personal experience with LED outdoor signage is non-existent. I've used it indoors on several occasions and then it is P1.6 or P1.2 that I have used. It's incredibly bright indoors and really not my favorite technology.

What is really lacking is the information on the technical aspects of these devices and displays. You almost always have to go directly to a manufacturer who is also often the installer and they will walk you through certain features of their product.

I think the real question is whether or not your budget allows you to get the product you want. LED video walls are expensive. The finer the resolution P8 over P10 for example, you will be paying for those extra LEDs and they will produce a finer image for when people are closer, but at 30+ meters, it doesn't sound like that extra resolution will matter.
