format for an HDMI device.
It is not a malfunction. Depending on the situation, some

"EXT-4", "EXT-5", "EXT-6" inputs and PC mode cannot be
selected in the sub-picture.
RGB input signal of "EXT-1" and "EXT-2" are not available in

While more than 99.99% of these pixels function properly, a
very small number of pixels may not light, or may light all the
time.
Please understand that this is not a malfunction.
