Yep, that's exactly it! It makes me very happy to know that I wasn't the only one to notice it(and it definitely felt like I was going mad for a while- seeing stutter where literally no tool could detect it). I found a forum thread on Dell's forums about it ages ago, I remember people sharing the refresh rate override fix, but I wasn't aware that Dell did eventually "fix" it in a later batch of monitor. That monitor did actually die for me literally 2 months ago(and just few months out of warranty, typical) but I was very glad to replace it with something else.
