I have displayed the same images on both monitors at 1:1 magnification. On HP monitor the images occupy less space on the screen. I measured the actual vertical size of the image on the screen and divided by the height of the screen. On the HP the ratio was about .52, on the Seiki it was about .76. To figure out the actual vertical resolution I computed (.52/.76)*1600 which is around 1090. So I reset my HP resolution to 1080 and voila, the two screens matched. It's not just the images, it is also the icons, etc. The Seiki is running 1080.

I don't know how that's possible. What resolution does the TV say it's getting? If you take a screen shot, is the image size 3840x2160?

If the Windows screen resolution settings says it's 3840x2160 and the TV says it's getting 3840x2160 and the screen shot is 3840x2160, then it should be running at 3840x2160. If images and text appear larger, it might have to do with the DPI settings and not the resolution.

If the video card were scaling 1920x1080 up to 3840x2160, then the Windows screen resolution settings would say 1920x1080 and the screen shot would be 1920x1080 while the TV would say 3840x2160.

If the video card were scaling 3840x2160 down to 1920x1080 (which normally doesn't happen), then the Windows screen resolution settings would say 3840x2160 and the screen shot would be 3840x2160 while the TV would say 1920x1080. If this is happening, did you patch the driver?
