Force HDMI to carry 5.1 Dolby or whatever

It's extremely annoying constantly losing that mouse cursor on my desktop that I have to move back

On the LG C2 remote, press ⚙️ → ⋮ → [Picture] → [Aspect Ratio] → try to expriment with the options there.

EDIT: Another option that you could try would be to hook up the Denon to the TV via the eARC feature of the TV. This will let the PC send the signal to the TV, and the TV sends the audio part of the signal to the AVR. (That is, instead of letting the PC send the signal to the AVR, and the AVR sends the signal to the TV.)

I experimented with these options but with no success. I'm thinking of just going back to connecting my RTX 3070 directly to my old Denon AVR and out from the receiver to the OLED. Since my AV receiver is so old, it doesn't support 4K/120hz, only 4K/60hz, but since I have an LG C2 with VRR and G-sync (screen tearing is the great bane of PC gamers), do I even really need 120Hz? 60 Hz is perfectly fine for movies and gaming + it dramatically saves power consumption. If I want to play a game at 120+ FPS, I'll just turn vsync off and use RivaTuner to limit and lock framerate at 120 FPS or whatever and let VRR and G-Synch take care of the tearing (though I noticed it's not perfect at doing this but certainly better than without).

It was probably a big waste to spend a small fortune on this OLED for its 120Hz features since I don't game with consoles so I may even return the LG C2 and get a QLED or at least a much more inexpensive OLED. I think the LG C2 is very overrated for the price and I have a month to decide if I want to return it.

My Emotiva UMC-200 is 11 years old, so it doesn't support 4K either. The solution that worked for me was eARC, but it took a while until I figured out how to set it up in my Sony Bravia XR-55X90J. I am quite happy with this TV, I bought it new at just 849 Euros almost half a year ago, but when it first came out (21 months ago or thereabout) it too was heavily overpriced IMO.

To remove the display from your desktop: How to Remove Display from Desktop in Windows 10.

Alas, I'm using the LTSC version of Windows 10 and the option doesn't show up.

Update: I did find the option to lock the cursor to one display in Windows 10. You just go into Display Settings from your desktop and drag the icon of the secondary display so that it's diagonal to the primary screen and now the mouse cursor no longer gets lost in the edges/corners of my desktop. This is great because it means I can now connect my RTX 3070 directly to the LG OLED and get that 120 Hz refresh rate and VRR if I need it though I normally stay at 60Hz for power conservation reasons. I only wonder if having this "phantom" extended display coming from my Denon AVR affects frame rates in games. I doubt it but I'll be testing it to make certain.

Btw, thanks, BuzzBuzzBuzz, for suggesting the DP-to-HDMI adapter procedure, and for the audio test files. Those should come in handy for testing and troubleshooting. So far everything sounds as it should in my system... finally

You're welcome! I can't seem to edit my post, but I've added test files with Dolby Atmos 9.1.6 and DTS 7.1.4 (what they call 11.1).

With the APO driver and Dolby Home Theater V4 hooked to my HDMI output, all channels appear where they should (properly downmixed) on my 5.1 system using MPC-HC, VLC, and Windows Media Player. The only exception is the LPCM file, which works fine in MPC-HC and VLC, but which Windows Media Player incorrectly assigns the surround and LFE channels.

Hi, I've tried all installation guides on this thread but I cant set the format to "Dolby Digital" at the advanced settings tabs, it always gives me the "Format is not supported by this device" error.

I have my NVIDIA GeForce RTX 3060 connected to my TV (Philips 50PUS7906/12) via HDMI and then the TV connected to the Sony HT-S40R 5.1 with HDMI ARC. It lets me use 5.1 surround only with certain apps, like the windows Netflix app and the Dolby Access test videos. My TV actually gets a pop-up showing that my PC is using Dolby Audio when those apps are using it, alongside the resoultion and display settings being used by the PC.

If I could make the TV register the PC as always using Dolby Audio everything would work fine, but I don't know if the ways used in this thread could help as I'm always stuck at the last step trying to set Dolby Digital as the format.

Hey! I suspect having the exact same issue as almost everyone else here. I'm trying to get 5.1 audio from: PC -> TV (VIZIO H1-65) -> Soundbar (V51-65).

First I want to make sure I understand the problem correctly:

The HDMI 2.1 connected from my pc to the tv grabs the audio channel info from the built in TV speakers, which are just 2 channels (stereo), when in reality the tv is just acting as an audio passthrough to the soundbar which supports 6 channels (5.1). Since this occurs windows just thinks you're connected to a stereo device so it defaults to 2 channels.

I've tried lots of the solutions in this thread and none of them have worked. First, I tried just using CRU to manually edit the audio information from the TV but that doesn't seem to work. Then I tried the APO driver route that was in the HD audio zip file and that just added the Dolby digital audio format to the list of available formats but every time I try to select it, it says an error occurred. I even tried connecting my PC straight to the soundbar but it was not recognized at all (not even in device manager).

If anyone has some of the same hardware as me and has figured this problem out or some other inisghts a response would be greatly appreciated!

Is there a firmware update available?

Is your soundbar set to Dolby Digital mode?

Did you install Dolby Home Theater V4?

u need a modified driver to unlock dolby digital over nvidia hdmi ( AlanFinotty driver mod)
then u go to audio settings > channel settings > choose DOLBY
now all the system will be encoded to dolby audio in realtime
BUT...maybe not make a 5.1ch output...just a stereo for the system itself
