Adding/Using HiDPI custom resolutions

[bluepr0]

You can look at the modification dates in the Overrides folder for the manufacturer. The file created by SwitchResX uses the year and week file name convention instead of the product ID. Post a screen shot of the manufacturer folder.


Strange that 2560x1440 scaled doesn't work. Show a screenshot of the Current Resolutions tab so we can see the supported scaled resolutions. Show a screenshot of the 2560x1440 timing information (double click in Current Resolutions - shows pixel clock and blanking info).

I don't know if the Intel HD4600 is capable of scaling 5120x2880 down to 4K. Can you find an example of any Mac or Hackintosh that shows this? How much VRAM is available? Try creating a scaled resolution that is 4096x2304 wide. Then also try 4064x2286 and 4128x2322. Maybe there's a 4K (4096) limit.

Thanks once again @joevt

So this is a screenshot of the Override folder before I did any modifications (as you can see the plist I made using the website is not present because as I said I deleted it to see if it was causing trouble with the SwitchResX file. You can also see that the SwitchresX file is there.

Here's an screenshot when I copied back the plist generated (the one ending in 7707)

Here's a list of resolutions from SwitchResX (in 2 images as it doesn't fit completely)

Here's the timings for 2560x1440@60hz

The plist I copied back also shows on SwitchResX now, but it doesn't change the resolution

I have tried with the suggested resolutions but they do not apply either

I do have 2GB of VRAM. Looking at the about my Mac... could it be a problem because I have selected the 21inch iMac SMBIOS?. I'm guessing it shouldn't because this is just like an external display for macOS.

Here's also the menu from RDM

And lastly, no... I couldn't find anyone that's using the 4600 with scaling

Current Resolutions would be easier to read if you sort by Resolution. Ok, it shows all resolutions less than 4K wide. And there's a HiDPI resolution for every other resolution greater than or equal to 1440x900. The label says "DELL U2515H" instead of "LG HDR 4K" because you didn't update the DisplayProductName in the override file ending in 7707. You should delete the override file and just use the file created by SwitchResX. I don't think you should have both.

Here's the timings for 2560x1440@60hz

Normal. It should be possible to have a normal and scaled 2560x1440 timing. You are running Mojave 10.14.6 and SwitchResX 4.9.1a4, so you should be able to enable the new "Show all refresh rates for scaled resolutions (after reboot)" option in SwitchResX General Settings tab.

The plist I copied back also shows on SwitchResX now, but it doesn't change the resolution

Maybe it's confused. You shouldn't have both your plist and the SwitchResX plist. Just use the SwitchResX plist. If it says the resolution is Active then it should appear in the Current Resolutions list but your screen shots did not show them? What's the timing info that it shows for those? If they are not in the Current Resolutions list, then check in the Custom Resolutions list.

I have tried with the suggested resolutions but they do not apply either

Well, you got 4064x2286 to work. Maybe 4095 is the max. You could try 4095x2304.

2 GB should not be a problem. My Mac Mini 2018 with Intel UHD Graphics 630 has only 1.5 GB and can go up to 6720x3780 (it's very strange that it won't go higher like 8K but that's a different issue - the 4600 might not be able to break the 4K limit).

Run "Open GL Extensions Viewer" from the App Store. Select HD4600, Core. Click Report. What does it say for Max texture size and Max viewport size? I don't know if this relates to maximum scaled resolution (probably not) but it seems to me if a texture can be greater than 4K then a scaled resolution should be allowed to be greater than 4K.

If there's a 4K limit in the driver, then someone would have to search for it. If the limit is there because of the hardware, then patching it won't work.

You have more than one LG HDR 4K display now? This current one has a newer EDID (same contents, newer manufacturer date) than one you sent August.

Gotcha! I've removed the file and rebooted

I had that enabled, but I disabled and enabled again. Then rebooted

I have tried the 4095x2304 and applied the resolution but looks like now I'm unable to change it and I don't get display signal, need to find a way to restore the hackintosh so I can have screen again. Maybe going into safe mode and deleting the SwitchResX file

Thanks! will report back on the rest when I can get screen back!

Max texture size: 16384 x 16384
Max vertex texture image units: 16
Max texture image units: 16
Max geometry texture units: 16
Max anisotropic filtering value: 16
Max viewport size: 16384 x 16384
Max Clip Distances: 8
Max samples: 8

Umm I haven't sent any new EDID aside from the one the other day. Maybe it was another user? I only have one LK 4k HDR display.

Looks like using only SwitchResX I can only enable 2560x1440, but it's not HiDPI. And 5120x2880 won't show up on Current resolutions even if it says enabled by using the plist file.

Ok, probably doesn't mean anything.

The file attached in #7,087 has the same display with same but older EDID. Oh, I see it was from your friend.

I guess a patch is required which might not be possible. Consider an eGPU?

I guess! I think I will leave it for now. Thanks a ton for your help <3

@bluepr0 I have also using LG UK850, but my default option in my MAC support scale 2K in HiDIPI mode. Maybe it come from VGA Card.

Thanks for your message. Yes I don't think it's a problem from the display because I'm able to get scaling when using it with my Macbook Pro. I think the main problem is either the hardware (Intel HD4600) or the drivers for it.

Hey everyone, I recently was given a Late 2012 MacBook Pro 15” with a destroyed display, so it is acting as a MacMini for the time.

I have an LG 32” 4K display and while I am perfectly aware that neither the display port nor HDMI can do 4k60 on this panel, I cannot seem to get HiDI 1080p at anything more than 30hz.
I can do 60hz 1440 or 1080 without the retina scaling.

Is this just a limitation of the system or is something amiss?

1080p30 HiDPI is actually 4K30 and 1080p60 HiDPI is 4K60 so you have to stay with 1080p30 HiDPI.

HiDPI resolutions use a frame buffer that is twice as wide and tall so that it can draw text and icons and other stuff at four times the resolution.
