Hello, I am trying to get nVidia GeForce (GTX 750 Ti in particular) work with 10 bit depth with Dell U2713H (supposedly 10-bit input, 14-bit LUT, 8-bit + FRC panel; connected to card's internal DisplayPort) in Linux.
Without success so far. NVIDIA X Server setting X.Org log confirms "30 bit Depth", GUI toolkits (Qt, GTK) show the color glitches as expected. After patching the gtk2+ and applying "native" to Qt graphic system the apps appear almost okay, just a few glitches remain here and there. But it does so also with 8-bit LCD (Samsung XL-20) - my assumption was that nVidia driver would not allow 30-bit depth unless there is a 10-bit display connected. "dispcal -v -yl -R" says the video card LUT appears to have 8-bit precision. 1024 grey ramp (encoded as 16bit PNG) displayed in Krita (with OpenGL backend active) shows clearly with only 8-bit precision. Finaly, two questions: x Anybody got GeForce cards working with 10-bit depth to a 10-bit monitor (native or FRC)? x Anybody uses 8bit+FRC display (Dell U2713H, Asus PA279Q and others) with e.g. Quadro card with 10-bit depth? (I am wondering, if the input of the display really is 10-bit or just 8-bit.) regards, Milan -- http://milan-knizek.net/ About linux and photography (Czech only) O linuxu a fotografování ------------------------------------------------------------------------------ _______________________________________________ Oyranos-devel mailing list Oyranos-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/oyranos-devel
