Solved Windows Photo Viewer picture quality issues on FULL HD

[hamburgcity]

Hi everyone, I am new here and I hope I can get help with a problem of mine. I have had the BenQ XL2420T Monitor for a couple of days now. I noticed that pictures look quite bad on it compared to my Samsung T220. After playing around with it I discovered that they only look bad when opened with the Windows Photo Viewer and ONLY on the BenQ. The pictures look absolutely fine opened with WPV on the Samsung. The funny weird thing, when I open the pictures on the BenQ using Paint or Photoshop they are all fine!!! It is so weird I dont understand it. I have made a video. It is a holiday pic so no jokes please IMG 5917 - YouTube

EDIT: I had to delete a file in color settings

I take it that file was an ICM profile?

My first guess would actually have been that Windows Photo Viewer auto-resizes photos to fit into its own window, and doesn't do the best job at that. But it's good to hear you solved the issue.
