Good day.... I'm afraid I can't answer your question, but I would like to make the following comment: The model is relatively old and I found the switching of sources, if this is also an issue for you, to be very tedious from the point of view of operability. There have been no firmware updates for a long time. In the meantime, I have discarded the monitor after a few years of use. The picture itself was actually quite good (FYI).
