Sorry, I should have clarified.
Some hdmi2av converters I've purchased have the same exact problem. ̶I̶ ̶d̶o̶n̶'̶t̶ ̶u̶s̶e̶ ̶t̶h̶o̶s̶e̶ ̶e̶i̶t̶h̶e̶r̶.̶ I returned many due to the crop issue, till finding a good one that works ok. However I purchased a second from the same vendor and it was a bad one.
