Hypermatrix said, in that thread regard the 2730MD model.
"This monitor uses the same multi-input board as the Witech Multi Limited Edition, and a monitor pulled before release from Achieva Shimian, and one released by First Semiconductor (I have a prototype of it). The reason for that is the 125hz operation is bogus. The dvi controller board allows an input of up to 125hz. So your computer will say "Heya. I'm sending 125hz (or 130hz, in my case) to your monitor! All is well!". The monitor is saying "Oh sweet! A 125hz input! I can totally take that! Thank you!." Then it tries to pass it to the Timing controller attached to the LCD panel and the monitor is like "Hey...TCON...buddy, I got 125 of these frames for you. What??? What do you mean you can only accept 60 from me? Fine...I'll send you frame 1, 3, 5, 8, 10, 12, 15, etc...."
Basically...it frame skips. It will accept an input higher than 60hz. The OSD will tell you that it's outputting 125hz. But it only ever sends a 60hz signal to the LCD panel itself. Sorry to burst your bubble."
