Working fine. I tried direct to HDMI earlier and it would not work - blank screen. It wasn’t until I set it up using another tv that it worked now going direct to the one HDMI port. Not sure if it now worked because it was already set up or something else changed. Just glad I have a resolution! Thanks for taking the time to help!
