vaz I don't feel spaced out. My neck and face and back of head get tight and tingly in as short as a few minutes, and that progresses into a headache with hours. It's like something is making me tense around face and head. Contrast that with staring at super old stuff for 12 hours with no problems at all...not even a twinge.
It's a mystery, isn't it? I don't have the symptoms you're getting but it's still a direct result of using new tech.
I've got two machines at my desk, an Acer 2010 tower and Intel 2018 NUC - HDMI cable going into monitor. 2010 machine is fine all day, no ill effects. 2018 NUC, within 20 minutes (same cable, same monitor) I get symptoms (heavy eyes, dilated pupils, brain fog), It felt like my eyes were forced open and wasn't blinking as much. When I used it extensively (over 8 hours a day for two weeks) and then switched back to my 2010 machine, I immediately felt the physical and mental relief. I forced myself to use the NUC for that long to rule out placebo and to see how bad it could make me feel, also if I could get myself through it by using it all the time.
My experience is nope. You might get more accustomed to the symptoms, but it's still affecting you in some way.
