==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:

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