These are capable of going up to 395mhz (maximum it can do can vary between 385-395mhz sometimes it is over 400Mhz on some lucky samples) on RGB (ycbcr444 NOT required, though also works)
No black pedestal problems, full range 0 - 255
Does not support 10 or 12-bit color though.
No smearing or any artifacts, low and high mhz. Perfect for using CRT displays with modern devices that don't have analog video outputs.
Doesn't require any additional power.
All converters are tested on a CRT monitor and guaranteed to work.
I buy these brand new and modify them with better case and cooling for the DAC so they work cooler and last longer. If you want it in the stock housing let me know. I am changing the custom housing design to make it look nicer so you may not receive the exact same case but I guarantee the circuit inside will be the same.

The case color will be white, I updated the design a little so no more screws showing up on top. You can see it at last images.
If you want a colour different than white I can print it for you if I have it at the moment, but you need to ask beforehand. There are some samples in last image.

It is listed as "used" as I open the original packages these come in and install a 3D housing and heatsink, it is technically no longer a new item. I also test them by using them on my own computer for some time. It is just how it is.
