Windows 10: Thumbnail Icons will not display large/extralarge

Hello everyone

I've been searching the internet and after finding no results on this question I made this post. I have a lot of video files stored, but when I go into the view tab on file explore and click display icons as large or extra large only some will display at these sizes. The rest only widen the area in between, but the actual image preview icon stays small. I've noticed that this has been a problem with hi res monitor's. I have a 2560x1440. Is there any fix to this problem? I browse a lot of video files at one time so I have to squint really hard or click on the video file itself to see what it is. Can I manually increase the size for the icons if there is no universal fix? Thank you for your time.

Thumbnails do not show for pictures

For Windows 10 thumbnail picture icons. This worked for me.

Control Panel. View by category. Large icons. Display. Personalization. Tools.

Folder option. View. First box unchecked , (Always show icons -----)

 

thumbnail size

Windows file explorer will not allow me to view my files as extra large thumbnails. I do have thumbnails but when I click on "extra large icons" the thumbnails remain the same size, but become more widely spaced.

 

I believe that you've been bitten (or are being bitten) by a default limit in the size of the Windows 10 Thumbnail cache. This means you may be held back by a limit on the number of thumbnails (or in your case, the number of large thumbnails) that Win10 can manage. See this TenForums thread (item#64) for a Registry hack that lets you increase the size of the thumbnail cache from the default value of 550 MB to 4096 MB (4 GB).
