I've had my 4730s for a while (details in my sig), all running perfectly with SwitchResX controlling 1600x900, finally made the leap for 1080p a couple of weeks ago - beautiful screen, seemed to work out the box, so I disabled SwitchResX and shut it down. Turn it on yesterday - my screen is all out of whack, exactly as in the first post in http://www.tonymacx86.com/hp-probook/81379-1080p-screen-issue.html
Well, nothing to worry about, right? Install SwitchResX back, alas it won't save settings anymore for whatever reason, just seems completely borked. It does display 1900x1080 in the list of possible resolutions, even has it selected, but the screen is still.. well, I don't even know what resolution it is, but it's very wrong... if I switch to 1600x900 and then back to 1900x1080, it becomes normal till next reboot. Later discovered that I can do the same via Display Properties, selecting "scaled", so SwitchResX seems irrelevant.
Search the forum, results seem promising: http://www.insanelymac.com/forum/to...-or-wrong-resolution-laptop-display-problems/
Alright, red flag came when in Step 7 my IODisplayEDID was exactly the same as in Step 4.... could be due to my messing with SwitchResX? Regardless, trying this method didn't solve anything for me. (Still, there was some confusion, so I am not ruling out operator error - first, there was already a folder named "DisplayVendorID-daf" that matched what it's supposed to be in my case, as well as which DisplayProductID to use exactly - but I'm pretty sure I got them both correctly, at least after different variations).
Now I recall I have a custom dsdt.aml created long ago... per RehabMan's instructions "If you ever make a hardware change or update the BIOS, you should re-patch your DSDT" in his generous post: http://www.tonymacx86.com/hp-probook/77057-guide-installing-mountain-lion-hp-probook.html
- removed my dsdt, installed his Mini-SSDT-DualLink.aml to /Extra/ssdt-1.aml. Now we're getting somewhere - for the first time, it was able to boot with a seemingly correct resolution, albeit no WiFi, battery, etc. Alas, generating a new DSDT with either MaciASL (RehabMan's patches) or the freshly downloaded ProBook Installer yielded essentially the same results - back to the wacky screen on reboot. Removing these "new" dsdt's didn't seem to help, as now even with just ssdt-1.aml I still get the stretched screen, unlike at the beginning of this paragraph
As some others before me, it clearly feels that this must be some EDID issue, considering it CAN be temporarily corrected within display properties, so I'd like to ask anyone who's been through this upgrade before - what am I doing wrong? Any opinions appreciated.
