DisplayPort supports FreeSync, but the FreeSync data block only works for HDMI and some laptops. There's no way to activate FreeSync with DisplayPort if the monitor doesn't support it.

Hello!

I realise this is probably covered somewhere very simply, but I'm hopefully asking a simple question.

I have a 3090 FE connected to an LG TV via a matrix switcher. The matrix extracts audio to a Sonos Playbar via optical.
The matrix passes through my TV's EDID which as I can see has been covered in this thread, means I don't have the 5.1 options in Windows.

What's the simplest way for me to make this audio-only EDID change so 5.1 shows up as an option for my HDMI 3090 output? (ELI5 please!)

Thank you in advance <3

1. Edit the CTA-861 extension block.
2. Edit the audio formats data block.
3. Edit the LPCM audio format.
4. Set max channels to 6.
5. Click OK on all dialogs.
6. Reboot.

Thank you for the swift response!

This does indeed work to get 5.1 options to appear, but I still can't convince my PC to actually play AC3/DD5.1 audio and this option never appears in that 'Spatial Audio' drop down, even when the number of speakers is correctly reported as 6.

After much googling I have actually found out how to solve my problem. I need an external USB DAC (like a Sound Blaster X3) that can do DD Live encoding and then connect the optical out from THAT to my soundbar. Which totally breaks my HDMI multiplexer setup but anyhow.

Just for future visitors: if you have a Sonos or similar soundbar that ONLY accepts Dolby encoded audio, you can't get this to work on Windows 10 without Dolby Digital Live encoding hardware. EDID is NOT your problem Smile

Oh yeah, apparently Freesync "works" on my monitor(XL2411Z) through DVI and I'm getting a Dell KDP70 BizLink DisplayPort to DVI (Dual Link) Active Adapter so I can once again run 144hz at 1080p.

But I seem to have issues with it, with most games blanking out my monitor when I have it on, how would I determine the Freesync range to keep it stable?

That's because the monitor doesn't support FreeSync.

Hello!

I'm currently trying to create a custom resolution for my TV (se39uy04) since whenever I try to put the refresh rate above 30, it sets itself to 656 x 496 and any other resolution will just be 4k@30 scaled down to the specified size. I've read that I need to change the DALNonStandardModesBCD2 entry but my computer seems to lack most DAL entries. I've already run the pixel patch.

Is there another way to unlock my TV's refresh rate so that I can hopefully reach 2560 x 1440 @ 72hz?

Currently running windows 10 with an ROG 5700XT.

Thanks!

That TV doesn't support refresh rates greater than 60 Hz, and it only supports 30 Hz at 3840x2160, so you need to choose a resolution that has 60 Hz available. I don't see what DALNonStandardModesBCD2 has to do with your problem, and you don't need the pixel clock patch. You should be able to add 2560x1440 @ 60 Hz as a detailed resolution. Make sure GPU scaling is disabled if you want the TV to handle lower resolutions.

I have no idea what changed but I ran reset all and deleted the profile I made and recreated a 2k@60fps profile and for some reason it now works?? Thanks for the input anyway. Now I just need to figure out why it doesn't allow the usb to update it... Sorry for the trouble!

i have an inspiron 620 running windows 7 pro with an AMD RADEON HD 6450 Graphics Card which comes with a maximum resolution of 1920 x 1280. Is CRU the right thing to use if i want to connect this system to an LG um7300pua 4k smart tv? After running CRU will 3840x2160 be in the list of resolutions in windows display settings?
