2K in film/video resolution is actually 2048 (based on the closest binary equivalent), not the metric 2000. 1K is equal to 1024 (a number you are probably familiar with from your monitor setting...), 4K would be 4096. You will need to ask the screen ratio, as "2K" probably refers to only the horizontal resolution. This link will be helpful: http://www.celco.com/FormatResolutionTable4K.asp holly
