I've been using HDMI-to-DisplayPort adapters and an HDMI switch for years. I had intermittent screen blackouts (each power outage lasted a second or two). Now my display images are very reliable, and the built-in USB switch makes switching between keyboard and mouse very convenient. I've been using this switch for three months and it has worked very well for me.
