Can you upload the JETI LiVAl measurement file? Use File -> Save, and highlight the 4 measurements. It will a *.spc file.Here are my JETI values from last night. I use Ted's 4-color, 100% amplitude test patterns. The sync number is high, and rather unusual, if you're accustomed to normal refresh rates of 60, 120, etc., but the JETI is very consistent with these numbers, so I trust the readings.
