revertive Posted September 6, 2011 Share Posted September 6, 2011 I have an ATI 4830 512MB, and i have an problem with it. I can only select resolution's which support 72/75hz or higher, i have read some other topics of people with 4800series cards who have/had the same problem. But there's never an answer in these topics. So right know i have 1280x960@75hz, which works but it isn't sharp. And with almost all other resolutions i can't select 75hz so they won't work. I hope there is an solution to this, because the native resolution 1920x1080 only supports 60hz Link to comment https://www.insanelymac.com/forum/topic/267305-ati-4830-stuck-75hz/ Share on other sites More sharing options...
