Maybe some models are better but I am satisfied with HL1 image quality.
One problem I have with the HL1 is that it is awful at playing video. I can visit YouTube w/ Microsoft Edge but the UI is so laggy I haven't been able to watch a real video.
I can listen to music from my local Jellyfin with the strange thing that I don't hear it in stereo but instead it is localized as a point source that I can hear behind me if I turn my back to the Edge window.
I've tried watching video through the Jellyfin web interface, I have no trouble selecting a video to watch but once I start the video I see the spinner spin and spin and spin. I see the HL1 has a HEVC codec built in, I assume I can transcode video to something it can stand.
The missing app I see is what you'd see in any movie with tech like this: something that lets a "controller" look through your camera, talk with you, put stuff up on your screen, etc.
More generally a problem I see is that I want to share the experience I am having with other people and as finicky as it is I'm a little afraid to give it to somebody else so they can see a "hologram". Of course I got this to help with software development for my art projects so that's kinda the whole point for me.
