Image Resolution Tutorial Basics - TV, HD, 1080, 4k, 8k, Megapixels, PPI, DPI! 

Amazing explanation. Thank you for your work!

Thanks for the great tutorial! you explain confusing concepts in a simple way.

I was confused with the mix of industry jargon that's used regarding TV screen resolutions; 1080p vs. 4K as an example with each referring to pixel counts along different axis' as you'd pointed out. I'll start calling 1080p "2K"... so there! This was far and away the most comprehensive explanation regarding resolution. Thanks!

good to know how this works. Nice explanation, thank you

This was the best tutorial to learn about image resolution. Great job!

This is incredible, I am doing full stack engineering, and want to understand the front-end thoroughly. What I would love to know is how the physical pixels the actual red/green/blue hardware pixels map to screen resolution pixels ?

For printing what is the best format for saving a photo file, jpeg, tiff, png... etc, thanks

thank you for exhaustive explanation.

Very clear explanation. Thank you so much!

I'm a newbie and I learned a lot, thank you.

you can also push the right click on the ruler and change directly from inch to pix or cm without going to preferences. just faster :p

Learned something new😁

Thank you, useful.

great explanation 👍👍

But higher resolution, explained simply, does it not mean more pixels over a standard area, as with dots per square inch. And if so, what is the standard area over which pixels are measured? Is it not per square inch.

In mirrorless cameras, viewfinder screen resolution is referred to in millions of dots. Why can’t we just use screen resolution units?

Thanks for the video, it is very helpful! But still I have a question - in example: If I have a photo camera with 42MPX sensor, and then i want to create JPG from RAW, how can I know what is the largest possible DPI during exporting, to not have to create an additional virtual pixels. In other words, how to connect the MPXs of the camera with PPIs. I made an experiment, and exported the same RAW photo to JPG as 300 PPI, and also as 72 PPI (and also as 10PPI), but with the same picture dimensions. I thought, that when I will enlarge the photo on the screen, the 72PPI will be much more pixelized than 300PPI, but, what surpirised me, after zooming the JPG they had the same amoun of pixels and they were exactly the same on the monitor.

If I want to play image on 16k resolution tv .Then what megapixel professional camera is required to capture the image so that it will be right fit for 16k television..

Voice clear better than last videos Could you do tut how to do , star rating system

Seems like ppi is by far the best way to show resolution for all screens. It actually tells you resolution without doing the math.

Please tell me 1366x768 It's is an 720p or 900p or 1080p

My phone resolution is 1080 x 2340 so how it means

So is 2340x1440. 2k? More or less

So, let’s get this straight, please. The MacBook pro is only 220 or 226 ppi. That is not even Full HD, right? So playing video that was shot in 4K or even full HD on the laptop is pointless, right? Thanks.
