Hmmm, I know you keep having trouble with my pics too while others are telling me they appear just a little over 800x600 so there has to be some setting or maybe your browser that is causing the issue. I really can't figure anything more on my end until I'm back home which won't be until the beginning of next week.
On a different note, I can't understand why my 4W c-mount 808nm build doesn't show a red dot at all. I've never seen an 808nm (unless it was really low output) where I didn't see that dot.
Black box for me, no videos however if I go to you tube all is well.
I have windows 10 on this machine and I checked on another machine running windows 7 and no videos, I have half a dozen computers, I will check them all after lunch including one that runs Ubuntu.
What are you running BowtieGuy? Don't tell me a 572 LOL
I believe I have solved my pics showing up at 4k instead of 800x600 in places (take a look at my 07E thread and they should all be good now). It's going to take a lot of pain in the butt work to fix all the others in other threads though.
Using my daughters windows 10 laptop all I see is a black window like others are saying.
