Cleaning out old files from my 6TB raid 5 box and come across some 8bit YUV 4:2:2 test patterns .mov's about 20Mb each.
720 59.94 , 1080i 29.97 , 1080i 25 , 1080p 23.976 , 2048x1080p 23.976 , SD NTSC 720x486i & SD PAL 720x576i
Just load the file on your NLE time line , it good to check your display on a regular basics and if you don't have a calibration Spider (colorimeter)
This is the next best thing or if you do then calibrate with there's files
