My 48" screen is 1080p supporting 1920 x 1080 resolution.

I need to design a canvas on my computer that will send to this screen via HDMI cable.

Should the dimensions of this canvas be

  • 1920 x 1080 pixels or
  • 2862 x 1587 pixels (because 48" converted to pixels equals this in Illustrator)

You should set your Illustrator canvas to be at 1920x1080 pixels if you are going to be outputting ONLY on your 48" LCD as final.

I believe you got your Illustrator canvas size of 2862 x 1587 by using the diagonal 48" multiplied by a 72 ppi resolution - doesn't work that way bub.

However, in the event that you might be using your artwork for print or anything else, I would recommend you to set it to a higher resolution that supports fine-printing, and also is in a 16:9 aspect ratio, and then output to a jpeg and downscale to 1920x1080 for display on your LCD. That would cover all bases.

Wikipedia would indicate that it's 1920x1080 (given the 16:9 aspect ratio). Not sure where 2862x1587 comes from.

1920 x 1080 *is* 1080p 16:9 aspect (widescreen)

To calculate use 1080 as the base number.

1080 * (16/9) = 1920

and... Since 720 is also a 16:9 aspect

720 * (16/9) = 1280

So 720p is actually 720 x 1280 pixels resolution

Forget what illustrator says. Pixels are an arbitrary measurement indicating the number of red/green/blue dots on the screen. The pixel count in illustrator is measured by multiplying the resolution times the ppi (pixels per inch).
