Adding/Using HiDPI custom resolutions

[jeerral]

Try creating a 3840x2162 scaled resolution. Then choose 1920x1081 HiDPI mode?

Not working. Nothing has changed after clicking on it

Why doesn't it say that it is scaled? Double click it to show what you did.

@Douirc I have the same monitor with the same issue on About this Mac. For me, if I keep windows open and reboot, when the system logs in, it moved the windows up making the top bar inaccessible. Its as though it logs in as 4K and then immediately switches to 5K. Is this happening to you?

@joevt I will go through the previous entries in this thread later today and post your suggestions from the other thread here.

Thanks!

Do you guys still have and use the Planar IX2790 5k Monitor?

Did anyone have stuck pixels and/or other issues?

I had one that I just returned and I'm not sure if I should try again with another unit to see if I get a better sample. I'm honestly somewhat convinced they make these exclusively from panels that didn't meet spec coming off the assembly line and were thus rejected for Apple iMac 5k and LG Ultrafine 5k usage.

But - I'd love to hear if maybe some people did get a defect free perfect panel and which retailer you may have used if so?

Thank you so much!

Hello, folks, I've tried to go through this topic and find a solution, but it's a bit hard without topic search function...

So, I have : 2xSamsung 4K LU28R55 (28" 16:9 3840X2160 @ 60 Hz) in portrait mode and LG 34WN750 (34" 21:9 3440x1440 @ 75Hz) 5 (28" 16:9 3840x2160 @ 60Hz) in portrait mode and LG 34WN750 (34" 21:9 3440x1440 @ 75Hz) in landscape connected to 5700XT / 10.15.6 via display port cables

My main issue is with Samsungs as once I enable HiDPI/scaled resolution my cursor position doesn't match position on the screen where I click, which really confused me when i saw it first time also considering that it's lag is not uniform between top and bottom part of the screen.

I would also like to get a couple HiDPI/scaled resolution settings for my main 34" 21:9 screen, as sometimes by the end of day my eyes really can use some break.
I've downloaded switchresX but it looks like I need to create proper modes manually.

Let me know if there are any guides/instructions available, and I will be more than happy to post my configs here once I resolve everything.

Thanks

Im trying to use some hidpi resolutions in my hackintosh HP 840 g3 running catalina 10.15.6. I found a plist file for my laptop with the following resolutions

My laptop originally had a crappy 1080 TN display which I replaced with a B140han01.3 IPS panel with the following vendor and product ID

    | |   | | |       "IODisplayPrefsKey" = "IOService:/AppleACPIPlatformExpert/PCI0@0/AppleACPIPCI/IGPU@2/AppleIntelFramebuffer@0/display0/AppleBacklightDisplay-6af-133d"

So I put everything together and got the following plist file.

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
  <key>DisplayProductName</key>
  <string>HP EliteBook 840 G3 Display</string>
  <key>DisplayProductID</key>
  <integer>4925</integer>
  <key>DisplayVendorID</key>
  <integer>1711</integer>
  <key>scale-resolutions</key>    <array>
        <data>AAAPAAAACHAAAAABACAAAA==</data>

        <data>AAAFQAAAAvQAAAABACAAAA==</data>
    </array>
</dict>
</plist>

However, after copying it to /S/L/Displays/Contents/Resources/Overrides/DisplayVendorID-6af/DisplayProductID-133d, it keeps showing the same resolutions.

Any ideas? Thank you.

I'm running a custom resolution of 3840x2160/60Hz with SwitchResX to my TV. Is it possible to create a 1280x720p HiDPI scaling that outputs the full 3840x2160/60Hz? How would I go about doing that?

Why did you have to make a custom resolution if your TV supports 4K?

Create a 2560x1440 scaled resolution. That will make a 1280x720 HiDPI resolution. The 2560x1440 will be scaled up to 3840x2160, or whatever resolution you choose as the Scaled resolutions base.

Thanks! My TV didn't accept the standard options. Had huge issues figuring out the correct timing for 60Hz to work.

Update: It works, but the image is much sharper on Windows with the same scaling. Is there a fix for this, or just a limitation of Mac OS?

What is the difference between the timing in the EDID and the correct timing? Show the two timings so we can compare.

Not sure what you mean by "sharper".

You are using a MacBook Pro 15" Mid-2015? 2.2 GHz or 2.5 GHz? How are you connecting the TV? It has an HDMI 1.4 port so it cannot to 4K 60Hz from that port. Use a DisplayPort to HDMI 2.0 adapter for that.
