[QUOTE="pigoo3, post: 1536495, member: 56379"] This won't be a 100% perfect answer (since the monitor I have is not the BenQ PB278Q)...but I think that the situations are similar. I have an Early 2011 17" MacBook that has a "Thunderbolt" port (similar to the mini-display port for video-out purposes)...with the older 30" Apple Cinema Display attached as an external monitor. It has a resolution of 2560 x 1600 (slightly larger than the BenQ monitor you mentioned). I bought this Apple 30" monitor used...and luckily it came with the $99 (US) Mini DisplayPort to Dual-Link DVI Adapter.:) Here's what I know (between the previous owners explanation & what I've learned since). The Apple 30" display was introduced in 2004...and was discontinued in 2010. In that time it was really never changed/improved...it just sold for about 6 years (until Apple came out with its currently available 27" display)...thus the 30" Apple display was basically 2004 technology. From about 2004 till approximately Early 2008/Early 2009 (depending on the computer model...listed below) all Apple computers capable of displaying a resolution of up to 2560 x 1600 on an external monitor: - Powermac G5's - very last generation 15" & 17" Powerbook G4's - MacBook Pros - desktop Mac Pros ...they all had a full size DVI port...and did not need the $99 Mini DisplayPort to Dual-Link DVI Adapter. Basically all these Apple computer models and the Apple 30" display were all of the same "vintage" from a technology standpoint. Then in around the 2009 time frame (when Apple switched the video out ports to the mini-display port or "Thunderbolt" port...this is when the $99 (US) Mini DisplayPort to Dual-Link DVI Adapter started to be necessary. Basically "something technical" occured when Apple switched from a full-sized DVI video out port to the mini-display port or Thunderbolt port...and this is when the $99 (US) Mini DisplayPort to Dual-Link DVI Adapter became necessary with really large resolution monitors. So long story short...if the BenQ monitor you mentioned needs to have the $99 (US) Mini DisplayPort to Dual-Link DVI Adapter...it must be similar (technically)...to my 30" Apple Monitor. But. The Radeon 5770 video card you have (if it's the genuine Macintosh version)...has two mini-display ports...AND one full-size DVI port. It's very very possible that if you wanted to connect the BenQ monitor to one of the 5770's mini-display ports...you would need the $99 (US) Mini DisplayPort to Dual-Link DVI Adapter. But since the 5770 has a full-size DVI port...the BenQ monitor may be able to connect thru that 5770's full-size DVI port WITHOUT the $99 (US) Mini DisplayPort to Dual-Link DVI Adapter (unless you have info otherwise). If you have info that says that this is not correct...then I guess you will need the $99 (US) Mini DisplayPort to Dual-Link DVI Adapter. Since I am not aware of an alternative option. Hope this helps...sorry for the super long story/explanation!:) - Nick [/QUOTE]
