==Bug detailed description==
-----------------------------
Monitor Manufacturer: ASUS
Monitor mode veision : PA238Q

HDMI display will show wrong picture on every interlaced scanning resolution. I
attach a photo that is what HDMI monitor shows. It's very low probability to
show a normal picture. 
Resolution details:
1920x1080i 60 1920 2008 2052 2200 1080 1084 1094 1125 0x15 0x40 74250
1920x1080i 60 1920 2008 2052 2200 1080 1084 1094 1125 0x15 0x40 74176
1920x1080i 50 1920 2448 2492 2640 1080 1084 1094 1125 0x15 0x40 74250

==Reproduce steps==
---------------------------- 
1. ./testdisplay -a
2. check interlaced scanning resolution
