Both the graphics card and the monitor should be able to > do the full resolution at 60Hz just fine. You need a DP cable that is able to handle a resolution of 4k@60Hz. Not all DP cables can do this. But if you use the cable that is delivered with your monitor, it should work for all resolutions/refresh rates as long as it is not broken. Sorry, but I can't say anything about the rest of your questions. -- Regards wabe
