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

[@nedrider]

Amazing explanation. Thank you for your work!

[@Daluke61]

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!

[@zacharysilva]

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

Thanks!

[@GerritforBazeja]

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

[@peshutanpavri1599]

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 ?

[@jessedt9837]

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

[@zrohit]

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

[@rizkgerges9286]

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

[@BMikel]

thank you for exhaustive explanation.

[@FollowAndrew]

You are welcome!

[@serhiikichuk]

Very clear explanation. Thank you so much!

[@sakethpavan4901]

Learned something new😁

[@ocamlmail]

Thank you, useful.

[@swingoutmuseum6454]

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

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.

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..

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

[@drmoezawaung]

Ppi is not resolution of a screen. 1080*1920 resolution and 14 inches screen Vs 1080*1920 and 28 inches screen……….. both screens have the same resolution. But different ppi. ………….higher ppi screen might have lower resolution than a screen with lower ppi.

[@drmoezawaung]

How many pixels a screen has is resolution……… how dense the pixels is shown by ppi . How big the screen is shown by diagonal screen size

[@WebVid]

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

[@prashanthkumar0]

great explanation 👍👍

[@duncanoo]

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.

[@FollowAndrew]

This is often a confused topic, as 'physical pixel' resolution is different that 'software resolution'. Essentially PPI doesn't mean too much, as it's relative. What you want to care about is the total number of pixels (horizontal and vertical).

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

[@FollowAndrew]

This sounds interesting. The html/css (front-end part) or the backend database/code part?

[@mba2ceo]

1080p is GOOD for under 60in TV ... wish MORE RND went in COLOR & UPSCALING than 8k size

[@azeezalshebli]

My phone resolution is 1080 x 2340 so how it means

[@oumuamua1963]

So is 2340x1440. 2k? More or less

[@elmag3869]

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

[@rockonmadonna]

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.

[@Melbester9]

Not really. It comes down to the dimensions of your MacBook Pro and the resolution that your screen is at. That's how you determine the PPI. Same with your phone and 4KTV or monitor.
