Your Computer Monitor size and DPI?

For those that use desktop or laptop computers, do you know how to find the model, resolution, and diagonal size of your monitor? Of course, a few folks only use smartphones and a few not yet retired may only use a computer at their workplaces. Someone with a MAC might add how to do so with those systems. In web communities, members use a wide range of computer products each with numbers of possible monitors and settings, so it is impossible to understand how images might look on other's systems. But one can at least understand part of that unknown with the following.

For those with Windows systems, press Windows key + R then type msinfo32 in the pop up window. In the new window, select Components...Display

On my Dell XPS 15 9550 laptop that shows a 4k display as:
Resolution 3840x2160

A second method is, press the Windows key then in the new window select Display...Advance Display Settings

But that does not provide the diagonal size. In my Dell case that is part of the model name, with 15 meaning 15.6 inches. Then one can also calculate the monitor dots per inch (DPI). In my case 3640/15.6= 233 RGB dots per inch.

However I use my laptop on a fancy mobile computer cart that stacks a 23.8 inch diagonal external Dell P2415Q 4k USB monitor just above the laptop that is on a cart shelf. So 3640/23.8= 153 RGB dots per inch. Under the above noted Advance Display Settings one may select between the Internal display and any external display.

One won't be able to determine an external monitor size by commands and instead would need to web search. In my case "Dell P2415Q monitor" showed links for that information. To find a display aspect ratio divide the width by height. For example 3640/2160= 1.68:1

Otherwise, to relate aspect ratio (ie 1.68:1) in whole numbers (ie 16:9) one will need to web search.

David has been waiting a few years to buy a large color accurate 8k PC DisplayPort 2.1 monitor, when product finally become available. At that time, will also need to upgrade my computer with a video system capable of driving such. Currently there is only one such 56 inch 8k monitor product, just introduced this year.
 

I have a high resolution monitor in my basement music studio that I use for the DAW, but for browsing the web, I had to increase the font size to make it easier to read. This computer in my enclosed patio is just a standard 1920x1080 with nice large text.
 
There are a number of Linux apps and terminal commands with which to collect hardware information. Here is the output from using "hwinfo --monitor":

Nice monitor! Do you use it for work or video games?
I'm retired, so not for work. I don't do video games either. I use Photoshop elements to restore old pictures. I'm not all that good with Photoshop, but it's nice to have a large monitor to work with. This one was not too expensive either. I believe I paid around $300 for it.
 
I lived with cataracts for so many years, so I never bothered with these new fangled computer phones that can be carried around in one's pockets, but now, with perfect vision, I enjoy looking at my 24" desktop monitors which is like stepping out into the world, but I have hell of a problem getting them into my pocket. 😊
