adrianjgsmith Posted February 28, 2015 Share Posted February 28, 2015 This evening I switched my pair of 1920x1080 monitors for a single LG Ultrawide 2560x1080. However I can't get this resolution selected in either the Clover GUI or OS X System Preferences (I'm running 10.9.5). System Preferences recognises the monitor as "LG Ultrawide" and in my boot.log there is a reference to "found detail timing 2560x1080" but I can't get higher than 1920x1080. Am I right in thinking that the EDID is being recognised correctly, but the VBIOS isn't providing the resolution? I've attached a boot log and my current config.plist. Help greatly appreciated!

adrianjgsmith Posted February 28, 2015 Author Share Posted February 28, 2015 I'm running a Radeon 6850, with Bulrushes framebuffer. I should also mention I can get the 2560x1080 resolution fine in Windows, just not Clover GUI or OS X. Link to comment Share on other sites More sharing options...
Allan Posted March 1, 2015 Share Posted March 1, 2015 Try this: config.plist.zip Link to comment Share on other sites More sharing options...
adrianjgsmith Posted March 2, 2015 Author Share Posted March 2, 2015 Thanks Allan. I tried it but just got black screen once it reached the login stage. What did you change, exactly?I've had a look at my cables and seen all my DVI cables are single link, so I'm sure that's not helping. I can get 2560x1080 over HDMI in windows, but I'm guessing that's not going to happen in OS X. I'll get hold of a Displayport cable and see if that changes anything.

Allan Posted March 2, 2015 Share Posted March 2, 2015 Try use HDMI port in OS X too. Link to comment Share on other sites More sharing options...
adrianjgsmith Posted March 3, 2015 Author Share Posted March 3, 2015 HDMI was my first go-to option, but I can't get over 1920x1080 with it. I have read of people with Macs unable to get beyond this down HDMI, but having success with DisplayPort. I've got a cable on order (along with a Dual Link DVI cable) so will see what that brings up when they arrive in the next day or so. Link to comment Share on other sites More sharing options...
adrianjgsmith Posted March 4, 2015 Author Share Posted March 4, 2015 Just for Posterity's sake: Using a DisplayPort cable and Duckweed framebuffer has allowed me to get the full 2560x1080 resolution. Now I just have to get that resolution for the Clover GUI... Link to comment Share on other sites More sharing options...
Allan Posted March 4, 2015 Share Posted March 4, 2015 Try put this in config.plist: http://clover-wiki.zetam.org/Configuration/GUI#ScreenResolution Link to comment Share on other sites More sharing options...
adrianjgsmith Posted March 5, 2015 Author Share Posted March 5, 2015 I tied inserting both 2560x1080 and 1920x1080 in the screen resolution (using Clover Configurator). Judging by my boot.log the resolutions are being spotted, but not utilised?

adrianjgsmith Posted March 12, 2015 Author Share Posted March 12, 2015 Thanks again for all your help, Allan. I was away for a few days but read up on the link you'd sent. In the end it was as simple as setting PatchVBios back to 'true'. I now have full 2560x1080 resolution in Clover GUI, Mavericks and Windows 7.
