30" Apple Cinema Display Low Resolution.

10 posts in this topic

Recommended Posts



I have a 30" Apple Cinema Display, a DL-DVI to HDMI adaptor and a 2013 MacBook Pro. That's all well and good, but the resolution of the Cinema Display is topping out at 1280x800.


If anybody could give me some ideas - as I'm stumped - that would be great, and your help would be most appreciated.


Thanks in advance.

When you connect an Apple Cinema Display (30-inch DVI) to your computer, you may find that the highest available resolution is 1280 x 800 even though the optimum resolution for the display is 2560 x 1600. This can happen if the display has a single-link DVI connection instead of a dual-link DVI connection.

Straight from Apple.

The power block, DVI cable and everything else associated with the 30" Cinema display is original Apple that came with the display. I saw it working just recently with the prev owner's PC.


The DVI to HDMI adaptor is Dual-Link, as already stated in the OP...

you may look for mini thunderbolt to dual link DVI to try it.


OK, but I honestly can't see why that would do anything, since HDMI can support 4K, surely 2560x1600 should be a breeze! :P


I have ordered one, nonetheless...

      1. I install 10.13.5 on PC and install latest Clover. Working fine with NullCpuPowerManagement.kext. Then I reconfigure config.plist to work with native power management but have kernel panic. Then I found kernel fixes for pentiums, add this to config.plist and have panic again. How i can fix it without using custom DSDT?

      P.S. Also why a have worked speed step with NullCpuPowerManagement.kext? Checked in HWMonitor. Also have good results in Geekbench4 - 3016/5227 points in single/multi-core mode (linux - 2861/4476, win - 3038/4850).

      2. GTS250 worked out of the box. But I have problem during starting with HDMI connection (lost signal to monitor). No problems with VGA. How i can fix it without using custom DSDT?

      I have a receiver with 7.1 channels, in which I transmit the formats Dolby Digital and DTS without problems by Windows, through the HDMI output of HD4000. On that same Laptop, I have the Hackintosh, with the High Sierra 10.13.6, and with audio enabled using AppleALC, but in the audio preferences, I can not enable the Digital audio format. Also did not find players like Mirillis SplashPro (which I have used in Windows) with the option of HDMI output Bitstream. Is it possible to enable this digital output on Hackintosh?

      VMQemuVGA display adapter driver for OSx86 running as a VirtualBox guest. The binary should work on all OSs from Snow Leopard up to Yosemite 10.10. It allows to set different screen resolutions in VirtualBox from System Preferences.   The changes I've made to the fork have been minimal.
