    PNG files don't scale with Display Scaling in Windows Photo Viewer


    I have two 4k monitors, so I have Windows display scaling at 150%. The only problem is that PNGs have begun acting a little off in Windows Photo Viewer. I've attached an image of two of the exact same file, only I re-saved one as a PNG (on the left). As you can see, the PNG doesn't scale at all, while the JPG is much larger and perfectly viewable.

    Does anyone know how I can fix this or what registry setting I can adjust? Windows Photo Viewer isn't exactly an application with settings. Worth noting it didn't do this until about a week ago when I tried to fix the order Windows 10 displays image files, so maybe even just showing me how the pngfile registry entry should look might help? Not positive.

    Thanks in advance!

    Use a better tool like Gimp. Photo Viewer is a basic tool that is not meant for graphic manipulation.

    I use Photoshop for manipulation. I literally just use Photo Viewer to view images because it's lightweight and simple. I just want all file types to scale equally.

    In Windows 10, Microsoft has virtually mothballed "legacy" Windows Photo Viewer in favour of their "modern" Photos App.

    It is necessary to reinstate the registry entries for Windows 8.1 Windows Photo Viewer in order to get the program working fully.

    As is the case for much of Windows inbuilt functionality, the possible registry settings for full manipulation of utilities and applets remain undocumented and hidden in obscurity.

    If you expect Microsoft to fix any bugs in the program, or for anyone to reveal Microsoft's deeply hidden settings to enable you to tweak the programs, you may be in for a long wait.

    When folk start revealing too much of the mechanics under the hood of Windows that make it tick, Microsoft make them an offer they can't refuse - Mark Russinovich & Bryce Cogswell of Winternals, now known as the Microsoft Technet brand of Sysinternals are a prime example of this.

    Different Viewer?


    You could try a different file viewer program.

    One of the first programs I install on any Windows install is IrfanView (I've used it for >12 years).

    If you install the plugin pack, it can handle sound, video and various document types, in addition to images.

    But how old is that version of PS? Gimp blows it out of the water, because it is a very good graphics and photo manipulation package.
