I have recently purchased a new PC and "upgraded" to windows 10 after my old machine began to struggle running Lightroom and Photoshop.
Using Lightroom for the first time on the new machine tonight, I noticed that there was a huge difference is sharpness between my developed RAW files in lightroom and my exported JPEG viewed through the Photos App in windows 10. The JPEGs were often very blurry in the Photos App. When I exported several copies of the same photo at 100% file size with very different sharpening settings applied, they often look identical when viewed in the Photos App - lacking sharpness and not reflecting the changes makes in LR. I've looked online, and see that the Photos App in Win 10 seems to have a major flaw that causes pictures to often not render sharply - making it totally useless as a viewer for checking the quality of JPEGs and comparing them.
I am wondering what windows 10 software others use to display and check their exported JPEGs? All I want, is a simple picture viewer than quickly and accurately displays photos resized to fit full height and or width of the screen, preferably with buttons to quickly and easily move on to the next/previous photo in the folder (to allow easy comparison between different versions of the same photo). I would like a viewer that shows them with dark background preferably, but this is not essential. Any recommendations would be appreciated.
On my old HP windows 7 machine I used a simple program called HP Photo Viewer - which did the job absolutely perfectly, but sadly doesn't seem to work in windows 10.
