updating the drivers from Version: 22.214.171.12490 to latest drive causes HDMI/SDI converter to not send a content to TV. Using the HDMI port to the TV works but not through the SDI Convertor. As soon as we us the older driver problem goes away.
Thank you for joining the Graphics Community. I am sorry to hear you are having issues with that driver version.
I was unable to find this specific driver version from our download site, please confirm this here: https://downloadcenter.intel.com/product/88345/Intel-HD-Graphics-530 Downloads for Intel® HD Graphics 530. So, the version you are referring could be provided from your computer manufacturer or Windows Updates. From my end, I recommend using the latest driver which you will find in the link above, the latest driver version is .4849(last four digits).
