lg wide monitor won't display full resolution on mac pro

So I thought by entering 60 Hz, I was actually exceeding the maximum setting. SwitchResX has the ability to read the EDID of the monitor and export it as a text file (I discovered by chance) and consulting that text file, I determined that although the display is rated as 60 Hz, it actually means 59.978 Hz. If not, you get a generic setting stretched to fit. If the graphics card is capable of supporting that exact setting, you get plug-and-play. He wrote back that there was an FAQ about this very issue that explains “why this is not possible on most Macs and what you can do to get your monitor working on these Macs.”īasically, every monitor has something called an EDID (Extended Display Identification Data) that describes its capabilites and preferred settings to the graphics card of the computer. Why does SwitchResX not offer this setting? Why should I have to do all this custom configuring? So I wrote to Stephane, the author, asking if it were possible he could add 2560 x 1080 60 Hz as a standard setting. These LG widescreen monitors are the leading brand. I’m not sure of the performance implications of this discrepancy, and maybe 50 Hz would be close enough, but I began to wonder… The recommended setting for this monitor is 2560 x 1080 60 Hz, but the best I could achieve with SwitchResX was 2560 x 1080 50 Hz.

But then there is “refresh rate” or frequency. There are the pixel dimensions or resolution (2560 x 1080), and I got this to work, and it fixed the stretched problem. The previous solution was working, but was not fully the recommended settings for the monitor. I don’t know if I should keep this monitor or not, but at least now I can try it out and see if I like it. You CAN get this monitor to work via HDMI, if you’re willing to go thru the antithesis of plug-and-play and rely on a piece of Byzantine shareware.īasically, it seems Apple no longer cares about HDMI and LG can’t be bothered to write a driver for Mac users. because the shareware has to be able to save a new custom monitor profile to the System file.īut it can be done. Talk about feeling beyond “pay grade.” All I know is it works.įYI, for anyone else who might find themselves up this particular creek in search of a paddle, what the video doesn’t show is that on any Mac El Crapitan and higher, you have to boot into “recovery mode” and “disable SIP” using Terminal commands. It led me to this link which reveals the secret lies in entering a value of 159.84 “pixel clock” (whatever that is):

OK, so after hours of trying to get SwitchResX to work, about 2AM I finally discovered a solution from reading YouTube comments on the video I posted above.
