Resolve Scopes: different values than on Ultrascope

We started using the built-in Resolve scopes, recently while working with both our old Ultrascope in parallel with the davinci scopes, we noticed that the levels on the waveform display in the built-in scopes are higher than on the Ultrascope display.
These are the specs:
Davinci Resolve Linux 12.5
Decklink Extreme 4K (output to ultrascope over SDI)
Nvidia GTX 960


Any help will be appreciated

Could this be a Video vs Data levels issue under Video Monitoring?

Haven't fired up my UltraScope in a long time, but I just did and I don't think I'm seeing any incongruities. Of course, Resolve's scopes are all based on 10 bit, so that could be an issue.

Did you ever track down your problem?

Just to elaborate on my last post regarding differing bit levels, pure white (100 IRE on a RGB Waveform) has the following 8-Bit and 10-Bit values in RGB and Video Color Spaces:

255 IRE -- 8-Bit RGB Color Space
235 IRE -- 8-Bit Video Color Space

1023 IRE -- 10-Bit RGB Color Space
940 IRE -- 10-Bit Video Color Space

Haven't fired up my UltraScope in a long time, but I just did and I don't think I'm seeing any incongruities. Of course, Resolve's scopes are all based on 10 bit, so that could be an issue.

What the black/white 0/100 correspondence in 8-bit or 10-bit is not the same range issue as the absolute calibration corresponding to the "top" and the "bottom" of the scale hashmarks, which in Resolve is a bit misleading, especially when it is calibrated in bit values. A waveform monitor should measure IRE when operating in 709 and then doing something like popping up a bar reference will show you what is what.
