This issue just started. Could be related to NVIDIA GeForce GTX 1660 Ti Graphics Card in my MSI Laptop. What setting could be off? In my Preview Screen, everything is normal, but when I switch over to the Output Screen the image is quadrupled in size for some reason. I can only see the upper-left 1/4 of the video image. Using the latest version of vMix and a Logitech Brio webcam.

Whatever input I use, whether image, prerecorded video or text, everything is expanded by 4 times in the output. Only thing visible is the upper-left 1/4 of the visual field.

Turns out this weird issue was due to a setting on my NVIDIA GeForce GTX 1660 Ti card in my laptop. There is an option called "Image Sharpening" in the NVIDIA Control Panel>>3D-Settings>>Manage-3D-Settings>>Global-Settings-Tab. This was Globally set to "Sharpen 0.50, ignore film grain 0.17". For vMix this must be set to "Sharpening Off". This can be done by going to the "Program Settings" Tab. This effectively turn the feature OFF for vMix. All other programs can take advantage of the advanced setting.

I had just watched a YouTube Video on this Control Panel for the NVIDIA GeForce and the YouTube author recommended changing this parameter to "Sharpen 0.50, ignore film grain 0.17". We will see if this breaks any of my other graphic software. Now I am suspicious of this setting.
