So do Samsung displays/TV's tend to work better in general?
Or is that just a coincidence?
I have same issues with hdmi to hdmi, but with the hdmi/dvi adapter everything is alright-clear fonts and the rest.My Samsung P2450 doesn't work well. Blurry fonts like other guys I found searching on google. I tried hdmi-hdmi and dvi- hdmi using Apple adaptor found inside. I installed tinker tools but it did't change anything. It seems to be an unresolved bug or so. Don't know what do but I'm thinking to take it back to the Apple store for refund.
My mini server is driving a DELL3007WFPHC Display at 2560x1600 using the Mini DisplayPort to Dual-Link DVI Adapter along with a Dell 2001FP using a HDMI-DVI cable with no problems so far.
24" LED Cinema Display - flickers and has other display irregularities. It's a known issue with 24" ACD and all Thunderbolt Macs. Firmware update is supposedly on the way.
