I have learned a lot from this, way more than I wanted. It also got rid of the LG monitor message that would pop up each time I restarted saying I was not using the recommended settings. The reds were a bit oversaturated under 50Hz, and things seem a little crisper now under 60 Hz. I now have updated graphics capable of natively supporting my monitor settings, and I no longer even need the SwitchResX shareware utility.Īnd it did seem to improve my display performance somewhat.

Zip file? WHAT zip file? It was like some dancing, monitor-nerd, Wu Li master who can only respond in cryptic zen hints: “Hahahah, Grasshopper, you must seek the zip file and all shall be revealed.”įiNALLY, I found the zip file, ran the script, and it required downloading and installing all sorts of developer tools and such from Apple (this whole time in way over my head, with terminal commands and "disabling SIP", and such ), but in the end, IT ALL WORKED!

He kept saying “you need to download the zip file”. That took some time, and some googling and reading various forum messages back and forth between Floris and other users, where he responds in limited English. (The hardest part was finding the link for the script itself! It was not at all easy to spot on the page and many many people miss it. This guy, “Floris497” in the Netherlands has created a “pixel clock patch” script that updates and extends the capabilities of various Graphics cards in older Macs. Then after more googling, I discovered this brilliant link: I wrote Stephane again and learned that “pixel clock” is essentially the bandwidth (screen size in pixels + refresh rate) and that on most older Macs there is a limitation of 165 MHz pixel clock, which is why I could get 2560 x 1080 50 Hz, maybe even 51 or 52 Hz, but not all the way to 60. Therefore, I entered 59.978 Hz in the appropriate field in SwitchResX (and matched all of the other exact settings from the EDID document), but I still couldn’t get it to take! Why? 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.
