I have a HP monitor that does 2560x1600. 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? Thanks Toasty, you the man. I was unaware that in Windows you can customize the dpi through the control panel. There is a window that allows you to magnify the screen image. On my machine connected to my HP monitor the magnification was turned off. On the machine connected to my Seiki it was set to the maximum, effectively turning my uhd screen into 1920x1080 (while maintaining 3840x2160). When I turned off magnification on my Seiki, it looked fine. It seems to be some type of dpi virtualization. It is unclear to me if they consider magnification an increase or decrease in dpi. If the screen were treated as though an inch were an actual fixed physical length on the screen then decreasing dpi would magnify the image. If setting dpi defined the length of an inch, then the opposite would be true. Leon |
