How to work an A0 and A1 construction plan format to a 50'' TV with quality vision?

I would like to have the ability to read a pdf construction plan format A0 and A1, but fully readable in 100% display on a 50'' tv screen. Can you explain to me, why when I have an A1 size plan printed on paper, which is the same size as a TV screen, I am able to see the whole plan and read the characters But PDF on a TV screen 50 '', I have to reduce the size of the image to 30% so that my plan is visible full screen? When I put the zoom at 100% I see only a small portion of my plan then must move the image from left to right and from bottom to top ... It's not functional and not practical! Why the resolution it's so excessive into a pdf plan VS a paper print? Do you have a solution to this problem? Is there specialized software in this area? Or a particular screen that solves this problem for contractors or professionals firms?

Many people assume that 100% means "the actual size". It doesn't. It's just an arbitrary measure (though you can adjust it in preferences). Acrobat doesn't know (or care) what size screen you've connected. So zooming in or out is normal. I'm not sure why you describe this as not functional or practical?

This is not functional and practical, beacause it's necessary when we working with a construction plan, to see the overview of the building and to be able to read the notes and writings. The drawings of building are very large, but with small police of writting for notes. They are drawn to scale (1:50, 1: 100 or 1: 150, etc.). This is why we print the plans on a large paper size and not on 8½ "x 11" paper. I would simply like to be able to view a shot on a TV screen in the same way that I look at an A1 format paper plan. This is not possible because the resolution is much too high on a pdf plan. I do not understand that in 2019-2020, that there is not already this technology of electronics plans?

Sorry, I have no idea, still, why you consider zooming as not functional or practical, and what stops this from being useful. Zooming doesn't seem like rocket science.

 

What do you mean, EXACTLY, by "resolution is much too high"? Do you mean you have to zoom to the size you need? Sure, of course. Or do you mean something else?

Hmm, is your point actually that you can't read small detail, on a 50" screen, if zoomed to view the entire page? So a problem with screen technology rather than viewing options? If so, what resolution is your 50" screen (width x height in pixels)? Many TVs have poor resolution compared to computer monitors, and bigger TVs get bigger pixels, not more of them.

It's most likely an aspect-ratio issue. Okay, your TV is 50" on the diagonal. And your A0 diagram is 57.3" on the diagonal. Close enough, sure. But even if they were both the exact same length of diagonal, they wouldn't be the same size.

 

That's because your A0 sheet of paper has an aspect ratio of √2:1 while the TV screen has an aspect ratio of something else (probably 16:9, but maybe something else and certainly not √2:1). Hold up your sheet of paper on the screen, don't just trust the 50" advertised size. Do you see how the screen is shorter and fatter than the paper? That's why.

 

If you want to project a full A0 onto a TV, then you need to know the height and width of the TV. The TV needs to be taller than 84.1cm (33.1") and wider than 118.9cm (46.8"). If it's shorter than either of these measurements on either dimension, then you can't project the entire A0 onto the screen without cropping part of it.

 

Does that make sense? Let me put it another way. Imagine you have a 3-4-5 triangle. You want to fit into into a certain rectangle. And the rectangle is advertised as being 5 units along the diagonal. "Perfect," you think, "my triangle is 5 units along the hypoteneuse!" But you try to fit the triangle into the rectangle, and it doesn't fit. They told you that it was 5 inches on the diagonal, but they didn't tell you that it was 4.58 units wide and only 2 units tall. The rectangle is wide enough but not tall enough to fit your entire 3-4-5 triangle.

 

You need a bigger TV. It has to be taller AND wider than your paper. You need to know those measurements and not just the length of the diagonal. Otherwise, there's no way to fit the entire paper onscreen. It's like trying to fit a 3-4-5 triangle inside a 2-4.58-5 triangle; you just can't do it.
