When I play purchased movies or tv shows in iTunes the video is completely pixelated (just dots of colors or stripes) making the video unwatchable. I'm running iTunes Version 12.11.4.15 (currently the most up to date) on Windows 10. All relevant drivers have been updated. I tried playing the videos in a separate library and I encountered the same issue. I have uninstalled and reinstalled iTunes and found the same problem. Any advice on how to fix this?
I have the same issue. I have a Dell Vostro laptop connected to a Dell 3100 USB3.0 Dock (with a LG 34" Ultrawide 34BL650-B monitor), running Windows 10 ver. 21H1 build 19043.1165) . I noticed when I disconnected from the dock, my iTunes videos (using v 12.11.4.15 for Windows) displayed as normal. I made sure to download and install the latest Dell firmware/drivers for the 3100 dock. Still iTunes videos pixelated as you describe.
I decided to revert back to the previous version of iTunes for Windows (12.11.3.17). Before doing so, make a copy of your iTunes .XML library file, by clicking on FILE, LIBRARY, EXPORT LIBRARY. You'll need that to rebuild your library.

After uninstalling 12.11.4.15 and components as described in the video, install your preferred version. To import your library .XML file, move (or copy) it into C:\Users\<USERNAME>\Music\iTunes, and click on FILE, LIBRARY, IMPORT PLAYLIST.
Hope that helps.

Make sure that you are running the latest drivers for your hardware.

tt2 Thank you so much for your response. All drivers are up to date for my computer and I am still encountering this issue.
Under Edit > Preferences > Playback try changing the video quality. Alternatively you might try rolling back to the last version of iTunes that worked correctly for you. See the bottom of Troubleshooting issues with iTunes for Windows updates - Apple Community for download links.
