Thank you to the people mentioning the same / continuing issue from Windows 10 machines running ultra-high (4K) resolution.
More people reporting the issue and asking, begging, even screaming for help with this issue cannot hurt but likely will not receive the response or results we have been seeking for years now.
I first ran into this with a new 4K Dell XPS 9500 running Windows 10 that I purchased for photo editing. If I connect it to an older monitor at a lower resolution the extra-large thumbnails works just fine. If I connect it to my 4K monitor it has the same issue as the laptop monitor.
For two years now, while searching for a solution, I have read dozens and dozens of forums and help pages with the begging and screaming for Microsoft to resolve this. Still an issue. There are pages of vids on YouTube about thumbnail size issues and errors. I have not researched them yet but will after posting this.
To the people here, and all the other pages on the net about this issue, suggesting reducing the resolution to fix the issue are ridiculous suggestions: Why the hell would someone pay for the high resolution just to reduce it to satisfy a ridiculous shortcoming by Microsoft.
With the 4K screens and monitors becoming the norm for several years now I cannot believe that Microsoft has not addressed the antiquated maximum thumbnail resolution/size.
Just a couple hours ago I finally upgraded to Windows 11 hoping that the developers would have addressed this. SOOO disappointed that it is still an issue. SOOO disappointing that Microsoft continues ignore peoples wishes and delete/limit options for the end user to customize and optimize basic settings to improve their productivity and experience.
If I am allowed a vote, I will vote with the people who do not like the “dumbing down” Microsoft has been doing to office and Windows.
OK, enough of a rant. For now. But keep up the pressure everyone. It cannot hurt. Maybe someone will come up with a fix that works. And again, NO, Reducing resolution is NOT a fix.
PS:
JOE300,
If your new laptop has a 4K screen you will likely have the same issue if you downgrade to Windows 10 since this is a maximum thumbnail size and the “large” thumbnails are already at or near that size on a 4K screen. At least that is what us using Windows 10 on a 4K machine or monitor have been experiencing.
