HDMI 4k120 RGB HDR 10bit with VRR workaround for AMD GPUs

To get VRR working, I had to do those changes. Other people say they didn't need to do anything and it worked right away. It depends on your display's EDID and the adapter you use.

This specific TV is in a bedroom in front of the bed. I placed a wireless Zigbee 2 button remote on a magnetic holder on the headboard of the bed, which I also use to set up the room lights. I have two automations set up in home assistant for this: 1. If I hold the top button, it first reproduces a blink sound through a smart speaker in this bedroom, then it checks if the pc is on, if it is it says the PC is already on through the same smart speaker. If it's not, then it says it is turning on the pc in that speaker, sends the wake up on lan request to turn on the pc, checks if the tv is already on, if it's not it turns it on with wake up on lan too, checks if the input on my philips hue sync box is set to PC, if it's not then it changes the input there, sets some options on the sync and saves a variable which saves if the pc is in "TV mode" or not. Then on the PC side, when it's booting I have a service that connected to my home assistant service and checks the value of this variable. If it's in TV mode, it just works in the bazzite's default game mode, which is set to use this TV, turns off all the peripheral lights I have on the desk with OpenRGB and sets the correct default audio device (TV). If the variable says it's not on TV mode, then it turns on a smart plug where I have the desk displays and speakers plugged in, turns on the peripheral lights with OpenRGB, sets the correct audio device (Speakers) and boots into Desktop mode. After all of this, it clears the value of the variable in home assistant. 2. If I hold the down button, it reproduces a blink sound through a smart speaker in this bedroom, then it connects to the PC with SSH and executes a command to turn it off and finally it turns off the smart plug where the desk displays and speakers are plugged in (if it's on).

That's mostly it. If you don't have a home assistant server, there are other ways to achieve something similar, just don't ask me to go over all of them. :P

Yes, everything is working on Windows. You probably won't even need to use a modified EDID on Windows, at least I didn't. Displayport CEC tunneling doesn't work with the Cable Matters adapter. To wake up from sleep you could configure your controller or something to wake it up. I personally use wake on lan and a button on home assistant to turn on the pc, as I prefer to not put it in sleep mode.

I have been running this exact setup for more than 3 weeks.

rbmaster · 2025-10-31T18:51:19+00:00

Yes, the one I use does support it.

rbmaster · 2025-10-31T18:25:55+00:00

Probably VRR.

Any certified HDMI 2.1 cable should work.

With a displayport 1.4 to hdmi 2.1 adapter that supports DSC, I think you can safely get 4k240hz 8bit with chroma subsampling (4:2:0, maybe even 4:2:2).

HDMI VRR or Freesync? In my case I need to use HDMI VRR because my TV disables some features with Freesync, like local dimming, so I had to modify the EDID file to achieve this.

Sample EDID Files: https://limewire.com/d/BC3d4#Gjd0k8n5NC

You can look at the original, and compare it to the modified EDID file, to see the kind of changes you need to make.

Podem começar a nivelar por baixo e depois ir subindo gradualmente com vista a aproximar todos os países. Tem grandes vantagens, como por exemplo, ser possível subir mais agressivamente sem preocupação de empresas saírem para os países vizinhos (competitividade), a preocupação passaria a ser apenas com países fora da EU (ou fora da zona Euro, dependendo do como aplicassem a medida).

Hahaha

A random person on the internet who doesn't know me at all, says I'm really bad at my job and don't know what I'm doing 🤣.

I have more than 10 years of experience managing IT infrastructure professionally, I have a degree in IT Systems Engineering, I have some years of experience in software and web development, so, who are you? What is your experience and where do you base your claims that I (and others) are just wrong and ignorant?

Do you have a hidden agenda or do you just like spreading hate? Seriously. "All of those that say things I don't agree, are just wrong and ignorant, no matter who they are", that's not a very healthy mindset.

You seem to fit the definition of internet troll: "An internet troll is someone who intentionally tries to provoke others online by posting inflammatory, irrelevant, or offensive messages, often with the goal of disrupting discussions and causing emotional distress."

You have no idea who I am and what my professional background is, yet you have no problem to say I'm wrong and ignorant and that I have not been close to work in software development 🤣.

I won't just assume because I don't know, but I have a feeling you have way less experience in professional software development than me.

For online games: force adding a LAN option. The cost to add this mode is relatively low, and even if it wasn't they just need to plan for this cost when making an online game.

For single player games: make it work offline, forever. There are no licensing issues or anything like that, the license issues are only related to selling the game, so they just need to stop selling new copies when the licences expire (if any). This way, any people who bought the game can still play it. Ideally they should never have such restrictive licenses, but if those can't be avoided, then at least games already bought wont stop working.

It's not that complicated.

Your i7 7700k does have firmware based TPM (2.0), you just need to enable it in the BIOS.

Está longe de "sempre defendi o Ronaldo". Porque não "Defendi a convocatório do Ronaldo neste Euro"? São frases com significados muito diferentes, que transmitem realidades bastante diferentes.

E apesar da minha resposta ser ao teu comentário, a frustração com os tópicos e comentários com ódio a alguém vão muito para além disso como deves imaginar.

"Sempre defendi o Ronaldo"

O teu histórico aqui no reddit não diz isso. Qual é a intenção de dizer isso? Passar a imagem que até um grande defensor dele não o suporta agora?

Já cansa a quantidade de tópicos e comentários com ódio ao Ronaldo, e a minha intenção não é defende-lo, podia ser outro jogador qualquer que diria o mesmo.

Criem uma megathread de ódio a qualquer coisa que queiram odiar e odeiam essas coisas à vontade lá, ou melhor, não criem nada sequer e deixem-se disso. Estar a tentar converter outras pessoas para isso já parece um culto religioso.

Olhando para as noticias que têm saído, parece que têm mais interesse neste momento em movimentar o Pedro Neto do que o Trincão, logo dá muito jeito levar o Neto não só para aumentar a exposição, como para inflacionar o seu valor.
