Windows 10: 4k Monitor Windows Scaling Resolution

Hi, I have a 4K 2160 x 3840 monitor for my Windows 10 PC.If i use windows display scaling set at 100%, all the icons are tiny, but when i do a screen resolution test using various websites, the results come back as 2160 x 3840.I used websites such as:https://bestfirms.com/what-is-my-screen-resolution/However, if i change my windows

4k Resolution scaling but then watching a 4k video

Hi,

I am building a PC with windows 10. I have yet to buy my monitor.

I'm considering buying a 4k/UHD monitor but given the issues you can have with scaling (i.e. when using program's that aren't set up to cope with the scaling and therefore show up blurred) I am wondering if it is worth it at this point in the 4k/windows
infancy? Its worth pointing out that I am thinking of buying a monitor no bigger than 24" so not using scaling won't be very good as the task bar will be tiny.

Also, (my main question) when you use the scaling its effectively at Full HD resolution, correct me if I'm wrong, so what happens when scaling is on and I want to watch a 4k video. Will it be shown in 1080p or 4k? How does it work? What is the scaling actually
doing.

Thanks in advance.

 

4k Resolution scaling but then watching a 4k video

Hi,

Thank you for posting your query in Microsoft Community.

First, let’s look at an example of why display scaling is needed in most cases when using a high resolution display with a Windows 10 PC. In our example, we’re using a 27-inch 4K monitor with a native resolution of 3840×2160. With 100 percent scaling — that
is, a 1:1 pixel ratio — the Windows desktop and user interface appears tiny, and is likely too small for most users.

To fix this problem without giving up on our 4K monitor, we can adjust Windows 10 display scaling options in Settings. With your high resolution display connected to your PC, head to Settings > System > Display.

Here, you’ll see a slider labeled Change the size of text, apps, and other items. With compatible hardware, Windows 10 will attempt to automatically set this value to an appropriate percentage when connected to a high resolution
display. However, you can manually adjust it by clicking and dragging the slider. Moving the slider to the left reduces the display scaling percentage, which will make things appear relatively smaller, while moving it to the right increases the display scaling
percentage, making things look relatively larger.

In our example, we’ll move the slider to a value of 150 percent, which will give us a user interface with the same relative appearance as 2560×1440, which is a common and certainly workable resolution on a 27-inch display. To see how the math works out here,
notice how 150 percent of 2560×1440 is exactly 3840×2160, our 4K monitor’s native resolution (2560*1.5 = 3840; 1440*1.5 = 2160).

If this scaled image is still too small, we can raise the Windows 10 display scaling percentage even higher. For example, a display scaling value of 200 percent would produce an image that is proportionate to 1080p resolution, or 1920×1080 (again, just check
the math to see that 1920*2 = 3840 and 1080*2 = 2160).

The benefit of this configuration is that you end up with a user interface that is the same perceived size as the one you’re accustomed to, except that it’s noticeably sharper because each UI element is being drawn with four times as many pixels as a standard
resolution display.

Also note that Windows 10 display scaling isn’t limited to those with high resolution monitors. While the feature is certainly most useful on these large or pixel-dense displays, a user with even a standard resolution monitor can adjust display scaling,
too, although raising the scaling percentage too much may make the Windows user interface comically large and unwieldy.

Hope this information is helpful. Please do let us know if you need further assistance, we’ll be glad to assist you.

 

4k Resolution scaling but then watching a 4k video

Hi Anup,

Thank you for your response.

So therefore is my previous point on certain program's displaying as blurry when scaling is used wrong? I.e. as they'll be effectively displayed similarly to full HD resolution?

Also, if I used scaling at 200% and I wanted to watch a 4K video would it be displayed at full HD (due to the scaling) or 4K resolution.

Thanks again.
