2K and 4K Resolution missing for External Display in Ventura [Fix]

2K and 4K Resolution missing for External Display in macOS Ventura: If you have a retina MacBook Pro and are using an external display, you may have noticed that the 2K and 4K resolutions are missing from the Display preferences. This can be quite frustrating, especially if you’ve invested in a high-resolution monitor. The good news is that there is a fix for this problem. In this blog post, we will walk you through the steps to get your 2K or 4K resolution back on your external display in Ventura.

The Problem

It can be incredibly frustrating when you’re trying to get work done on your computer and the display suddenly goes blank. This is especially true if you’re using an external display, like a projector or an extended monitor.

There are a few possible causes for this problem, but the most common one is that the 2K and 4K resolution setting is missing from your macOS Ventura Display settings. This setting controls the width and height of your display, and without it, your computer doesn’t know how to properly scale the image for your external display.

Fortunately, this is a relatively easy problem to fix. In most cases, all you need to do is add the 2K and 4K resolutions back into your macOS Ventura Display settings. Here’s a step-by-step guide on how to do that:

The Solution

If you’re running into an issue where your external display’s resolution is missing in Ventura, there are a few things you can try to fix the problem.

First, make sure that your external display is properly plugged in and powered on. If it’s not, that could be the reason why its resolution isn’t showing up.

Next, try restarting your computer. This will sometimes refresh the display and allow you to see the resolution options for your external display.

If those two solutions don’t work, you may need to update your graphics drivers. You can usually do this through your computer’s manufacturer website or by using a driver update tool.

Once you’ve updated your drivers, restart your computer and try again. Your external display‘s resolution should now be listed in MacOS Ventura!

How to Fix 2K Resolution missing for External Display in Ventura

If your external display doesn’t support 2K resolution, you can still use it as a second monitor. All you need to do is change the resolution of your external display to 1080p. To do this, go to System Preferences > Displays > Resolution and select 1080p from the drop-down menu.

If you’re using a Macbook Pro with an HDMI port, you can also connect your external display to one of the Thunderbolt 3 (USB-C) ports using a USB-C to HDMI adapter. Once your external display is connected, go to System Preferences > Displays > Arrangement and check the “Mirror Displays” box. This will duplicate your Mac’s display on your external monitor.

How to Fix 4K Resolution missing for External Display in Ventura

If you’re having trouble seeing 4K resolution when using an external display with your Ventura computer, there are a few things you can try to fix the problem.

First, make sure that your external display is actually capable of displaying 4K resolution. If it’s not, then you won’t be able to see 4K resolution no matter what you do.

Next, check the cable that’s connecting your Ventura to the external display. If it’s not a HDMI 2.0 cable, then it won’t be able to carry the 4K signal from your computer to the display. Make sure you’re using a compatible cable before proceeding.

Finally, go into the BIOS of your Ventura and make sure that the “DisplayPort 1.2” setting is enabled. This will allow 4K resolution to be sent over DisplayPort connections. Once this is enabled, save your changes and exit the BIOS, and you should be able to see 4K resolution on your external display!

How to implement the solution

If you’re seeing the dreaded “K and K Resolution missing for External Display” error in Ventura, don’t despair! There is a relatively simple fix that should get things up and running again in no time.

1. The first thing you’ll need to do is open the Registry Editor. You can do this by hitting the Start button and then typing “regedit” into the search bar.

2. Once the Registry Editor is open, navigate to the following key: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Class\{4D36E968-E325-11CE-BFC1-08002BE10318}

3. Now, you’ll need to create a new DWORD (32-bit) value. To do this, right-click on the empty space in the right pane and select “New > DWORD (32-bit) Value”.

4. Name this new value “EnableUnsupportedDevices” and then double-click on it to open its properties window.

5. In the properties window, change the “Value data” field to “1” and then click “OK”.

6. Close the Registry Editor and restart your computer for the changes to take effect.

That’s it! Once your computer has restarted, you should be able to use your external display without any issues.
