I'm using a 24" Apple iMac running 10.5.8. I recently purchased a Hanns-G HG281D, which is a 28" LCD.
It's connected to my computer like this:
iMac -> Mini DVI to DVI adapter -> DVI to HDMI Cable -> Display:
Unfortunately, there's a nasty flicker in the screen. My first thought was that it was a refresh rate, unfortunately, I can't change the refresh rate for the display. I can't seem to get a screen grab with the menu open, however the following are the options:
- 50 Hertz (PAL)
- 59.9 Hertz
- 60 Hertz (NTSC)
Number 1 and number 3 are greyed out. I can't select them.
For the record, I'm an Australian who recently emigrated to the USA, and I brought my iMac with me. So the iMac is an Australian model (for whatever it's worth) and the monitor was just purchased from Newegg, and as such, is an American model (again, for whatever it's worth).
I've read a bit about acceptable timings for displays, and it would seen the 2600HD in my iMac should be able to drive the display to at least 60hz. (Ideally, I'd like to see 75, as eye strain is a big issue for me, and part of the reason I'm moving to a larger display).
