In the posted SMPTE pattern of 1920X1080P it is from a Digital Video Essentials Blu Ray direct from player to internal Moome. This pattern has been very usable and the standard barer end stage testing and verification to confirm native resolution verification on the screen. This is how we know we're 1080P capable, to put it another way.

And after using this pattern and others, you'll learn other things about it to helps reveal things about the video chain. My go to pattern for several checks, though it's not the all-in-all for absolute bandwidth confirmation...that's another subject, but for now let's just say it's the cats meow.

Now, using this pattern for years and reading and learning about other test patterns, something I've gotten to do a lot of over the years, you'll even come to know that not all test patterns are properly used, or that some test patterns are drawn wrong or not displayed properly. And this can be a subject of debate or discussion, but when also dealing with various commercial pattern generators, you find this same pattern shown very different. That is if you pay close attention to the pattern or use it enough to learn some things about it.

As mentioned, the posted one (below) is from DVE. And of all the SMPTE patterns I use and have used from various other sources, this one is the worse....why because all the line groups touch another line group (only the second from the top/right is almost not touching another line group). None of the lines should touch another line, because when the lines touch it creates an overall distortion in the center pattern group.

Taking this morning on my screen, and the focus is not the best.

That looks like the ectoplasm from Ghostbusters. Somewhere Bill Murray is saying "I've been slimed" Laughing

What's the purpose of the potting exactly? To prevent the user from accessing certain pots (so they don't screw it up?) Keep people from seeing components that you use in your modifications? Both? None of the above? Very Happy

I thought I had one other person I was waiting on for the free upgrade. They would have the later mini board, that has the single chip on the mini board (not the three 8 pin SOIC's). This is the version I would be improving on at no cost. And one previous customer that was considering changing tubes that wanted to purchase an upgrade earlier this year. That is the person I've been holding the only other mini board I have. They called this week. They had left a 02 VIM with me for this already. I suggested they do it right around the time they re-tube.

So the free upgrade would have the mini board with the single chip on it. The one with the three 8 SOIC would also require a new mini board upgrade with the single chip, but that one I'll not be able to upgrade being out of mini boards altogether. I'm not making anymore mini boards and was holding that one board I have for the person that called the other day.

So at this time, I would consider all the free upgrades to be done. And definitely still no new mods as no parts are available to do so.
