Plz tell me wat r the things that one should be carefully before editing !

I don't know much about the specifics of EDID. Read here: http://en.wikipedia.org/wiki/Extended_display_identification_data
 
According to my R&D,
I had Gradient issue so i searched for soln, n it was changing Basic Param to 90 from 80 in EDID
so i made kext DisplayMergeNub.kext n fixed the checksum.
But den then the chroma n Display descriptor n Size were wrong, but gradients r gone.
Den Fixedid was hard to understand
then i made Display Override file n added
1.80 -> 90 for Gradient.
2.Display Size Info.
3.Chroma Info for MacBook Pro
4.MacBooK Pro Descriptor.
5.Sony Vaio Descriptor.

Then i placed It in /System/Library/Display/Overrides
If something is wrong plz lemme know !

Otherwise display is working Great :)
 
This guide did not work for me. Difference is that I'm using a desktop computer through VGA, is that the issue?

The resolutions appear in SwitchResX, but they show up as invalid.

Desktop questions should be asked in the desktop section. As far as I know, the method could work on an external monitor. Perhaps you don't have QE/CI implemented correctly.
 
Great guide! easy to follow and worked out great.

-I have a 13" 1080p display and I'm trying out the 1600x900 HiDPI resolution.

I'm not sure if this is a normal side effect, so I might as well ask. The HiDPI mode doesn't really display everything correctly, I'm assuming this is because the 1600x900 projection is meant for a 3200x1800 display. for example, small objects like the lines on the "notes" icon on the window controls (close, minimize, zoom/fullscreen) have jagged edges. and are imperfect circles. This makes the HiDPI not the best option in terms of clarity. I did a screen grab at 1600x900 HDPI and then viewed it in native resolution. The image is indeed pixel perfect 1600x900, I'm assuming this is basically what it's like if I blew up a 1600x900 image on my 1080p screen and viewed it, since there aren't exact multiples, the screen can never perfectly display it. Is it possible to get perfect (or at least close to perfect) shaped at a decent density? are my only options 1366x768 for near perfection and 960x540 for perfect scaling?

This is somewhat OT but it may be related so I'll throw it in here. The edges around the labels in my downloads stack are jagged under all resolutions. I've tried toggling font smoothing but I think there may be some sort of non-font AA value somewhere... thanks!

Yes, it is an artifact of scaling to non-multiples. It is present on the retina MacBook Pro as well, but not as noticeable because of the small pixels.

The jags are because of the relatively low resolution. On my system here, the labels are a gray over (mostly/usually) white background, so they are not as noticeable. But any stark contrast will tend to show them more.

You can only hope for higher resolution displays to become more common.
 
Hey People!


Can someone help me to change the Display Preference Pane on my Lenovo U530 that it looks like on this screenshot?

adjusting_display.png

I have read in this support document from Apple at selected 4k displays the menu will automatically change if you used one of them - https://support.apple.com/en-us/HT202856

Would like to have this Display Preference Pane on Lenovo U530 with for example, the following resolutions 1280x720hdpi, 1440x810hdpi, 1600x900hdpi and native 1920x1080

I have the multitouch driver installed on my Lenovo and want use this menu it is much more comfortable to change the resolution with the fingers.

How can I activate this menu? Do I need to edit or change a plist file? or I have to use the display ID of one of the supported screens or the retina display from Macbook to unlock it? Would be glad if you professionals can help me!

Sorry for my bad english! :think:

Seems likely there is something hardcoded in the system to detect high resolution displays and show this menu only when the native resolution of the display is retina+.

Yes, this Display's show this Menü:
  • Sharp PN-K321
  • ASUS PQ321Q
  • Dell UP2414Q
  • Dell UP3214Q
  • Panasonic TC-L65WT600
is there no chance to simple add a file that the System think the internal Display is one of this 5? Not so simple ha?:cry:
