Try these settings. Your GPU is probably too weak for more aggressive settings:

• Chroma: Bicubic100 + AR
  
• Image: Lanczos3 + AR
  
• Image doubling: Off
  
• Upscaling refinement: Off
  
• Artifact removal - Debanding: Off
  
• Artifact removal - Deringing: Off
  
• Image enhancements: Off
  
• Dithering: Ordered
  

I finally found the problem ... It was just coming from that on the HP ProBook 450G3, the Graphics combo did not have enough power ... And on my current laptop, I just had to change 2 small settings using NVidia Inspector ... Everything is now working perfectly and flawlessly ... Thanks to all who have helped me ...
