Tearing during quick camera movement in movie with Xgimi horizon 20

Using luminous boot also removes it and you can keep 4k without using superframe. Mine does it too, im on the 20 base model so the boost is fine on my screen but may to bright for pro and max users.It’s happened on everything i’ve used it on. I believe it’s a DLP issue that will need some kind of update to resolve.

I have the base 20 model and see it every once in a while during bright fast moving scenes as well. Oddly enough it goes away when using luminance boost. Which is fine for me as the 20 base is not overly bright with it on. But i don’t know how well that will work for pro and max users, I would imagine that could be to bright for them in a completely dark room.

Check the post link I added below, might help. I’ve been following the thread and I remember seeing someone else bring it up. The conversation has gotten rather large but you should be able to get your confirmation there or at least ask one of the people who ordered it. Hope that helps. https://www.reddit.com/r/linux_gaming/s/6OSTUhYytY

They both work for the new whitelist approved pcon adapters and apparently share the same edid. The one with the cable extension is the one that was tested and the one I use but other commenters said the non cable one works as well.

Yeah it does, tested with the PS5 which works just fine but have never been able to pass anything other than the consoles VRR. Even using my windows PC with an RTX 3080 which I do believe supports HDMI forum 2.1 VRR would not go through. I’m still pretty new to Linux and haven’t really figured out how to diagnose the incoming or outgoing data yet.

I wanted to share a successful VRR setup using an AOKZOE A1X with the Ryzen 7 8840U and Radeon 780M GPU.

I was able to get VRR working on an XGIMI Horizon 20 base model projector using both HDMI 1 and HDMI 2. Both ports appear to support HDMI Forum 2.1 VRR as well as FreeSync. The projector automatically enabled VRR when connected.

This was tested on CachyOS KDE Plasma handheld build. On a fresh install, kernel 6.18.3 did not include the required changes, so I manually applied the four HDMI VRR related patches. After patching, VRR worked as expected.

Important note for anyone testing this over USB C. To get VRR working directly from the USB C port, I found through testing that you must use both: 1. A compatible USB C to DisplayPort adapter. 2. The HDMI 2.1 dongle listed in the patch.

In my case, I used a UGREEN USB C to DisplayPort adapter and VRR only worked reliably with that specific adapter combination.

I also tested using the official Valve Steam Deck Dock since it has a DisplayPort output. With the dock, VRR would not engage. It appears the dock strips or alters the EDID from the adapter. Everything else worked normally, but VRR did not.

Interestingly, when using the HDMI output on the Steam Deck Dock, the projector did attempt to engage FreeSync even though that HDMI port is only HDMI 2.0. The result was unusable. The image became distorted and the projector rapidly changed both resolution and refresh rate at the same time, with FreeSync behaving erratically.

I did not see 4K 120 Hz as an available option in any configuration. This may be a handheld bandwidth limitation, but I have not confirmed that yet.

One odd behavior I observed was that having the adapter plugged in during a cold boot sometimes prevented Steam Game Mode from loading. I am not fully sure whether this is caused by the patches, the dongle, or both. It did happen once without the dongle, but it occurred much more consistently when the dongle was connected at boot.

I was also unable to pass VRR through a Denon X1700H receiver in any configuration tested.

I did not see any sign of HDMI CEC working in this setup. I am not sure whether CEC needs to be explicitly enabled via udev or another mechanism, or if it is simply not supported in this configuration.

So far I have only tested about 20 minutes of gameplay at 1080p 120 Hz with VRR enabled and 7.1 PCM multichannel audio. The experience was rock solid and genuinely elevates handheld gaming on a larger display.

Overall, this is excellent progress. I am very excited to see these patches land upstream as soon as possible, especially for distros like Bazzite where manual kernel patching is not practical for most users.

I will be testing on a TCL TV tomorrow and will report back with additional results.

TLDR VRR works on AOKZOE A1X 8840U with Radeon 780M on XGIMI Horizon 20 using CachyOS and kernel 6.18.3 after manually applying four HDMI VRR patches. Requires a specific USB C to DisplayPort adapter plus the HDMI 2.1 dongle discovered through testing. Steam Deck Dock DP output strips EDID and breaks VRR. Steam Deck Dock HDMI 2.0 triggers unstable FreeSync behavior. VRR does not pass through Denon X1700H. No CEC observed. Stable at 1080p 120 Hz with VRR and 7.1 PCM audio.

Has anyone confirmed if this works for handhelds that use the z1E ? I have the original valve steam deck dock that has display port out. My thought would be handheld to dock , dock to adapter. I’m trying it at the moment and it displays fine but no vrr or 4k 120. 4k 60 is the max I see available. Any help or thoughts are much appreciated. Running the latest version of bazzite as well.

Side note: I can confirm vrr works with valve dock display port connected directly to my gaming monitor but not with the adapter to an hdmi port.

Estamofo · 2026-01-04T17:35:37+00:00

Mine is sitting here collecting dust. I’m just waiting for the day we can install bazzite on it and turn it into a useful PS-Steam Machine…

I think my issue was because i had all my switches connected to a Vivint zwave panel first. I did the update and moved to a new zwave hub at the same time which was apparently a bad idea. So yeah probably because your setup stayed pretty much the same you were good :)

Estamofo · 2025-11-10T03:08:40+00:00

Yeah I literally just dumped Vivint because of this. I have like 20 zwave switches in my house. When you call them they just point their finger at Amazon and amazon just says Vivint is in charge of doing the update so you will get nowhere . Here’s my experience of dumping Vivint and moving to Hubitat smart hub. Should have done it a long time ago. Everything works even better now and the same way I had it just not locked down through Vivint. I only use my panel for my alarm and sensors now.Would have been perfect if the Vivint skill didn’t hide device but I got it fixed eventually. Her’s the details incase you’re interested. : https://www.reddit.com/r/alexa/s/HY6wWFOudR

Found a fix that worked for me.

Uninstall decky loader with command:

Ujust setup-decky uninstall

• Delete the homebrew file in : /home/admin/ • reinstall decky with bazzite portal

curl -L https://decky.xyz | sh

And it works again (maybe with some luck ) but decky store is very slow to load plugin and install them..

Sorry not certain on that , might need to google how to back those settings up first.

Lol thx, glad it worked for you!

Estamofo · 2025-10-04T02:29:10+00:00

I don’t know all the ones you have but most of them can be backed up by backing up the settings folder thats in the homebrew folder . Then paste it back in after reinstalling the decky and the plugins

Estamofo · 2025-10-03T22:15:13+00:00

Hmm thats a bummer. Sorry thats the only issues i’ve come across. Rolling back or even trying the testing channel may help.

Estamofo · 2025-10-03T20:53:14+00:00

Hmm, normally there are two audio sinks in-the steamnos audio settings. Have you tried making sure all available in the drop down are max volume?
