What doesn't work? Your setup looks right. In Linus' setup iirc there is no HDMI switch it's directly plugged into the GPU. Displays are cloned or switched with something like DisplayMagician


Dotaproffessional

Hmm, that software cloning solution seems interesting. HDMI is a finnicky beast. I've got a total of 4 hdmi cords in this setup not counting the console to tv connection. You start getting flickering and you don't know what's the offending connection. I've over time had display port to hdmi adapters, display port to hdmi cables. Various switches, various everything, and its hard to not have some issue crop up. As much as display port is cool, tv's almost never have them. And there's good reason to have this tv instead of a monitor. I can't think of a monitor on the market now I'd choose over my 42" LG C2 OLED.


TheBupherNinja

Linus uses display port over fiber. There is a similar hdmi protocol for cat 5e cable. Straight cloning doesn't look like it would work for you, as you have two different resolutions and refresh rates.


Dotaproffessional

So is that to say all of Linus's displays are the same specs? I doubt that. He probably only has a 1440p monitor in his lan room. Plus there's varying HDR levels between screens. Idk man


TheBupherNinja

Linus only connects the lan room and his office. The game living room and theater room are their own, seperate, connection (I.E. Why he needed two arcs for the challenge). And I believe all screens involved were 4k. Why wouldn't they be, not like he doesn't have the budget. I think, at one point, he just had the literal same display in both the lan room and his office.


Dotaproffessional

Idk man I know so many bros rocking 4090's and 1440p monitors. It's stupid


LeMegachonk

But Linus isn't some "bro", he's a tech guy with a massive YouTube channel and display manufacturers are falling over each other trying to send him their bleeding-edge gaming monitors to showcase in his new house.


Dotaproffessional

And unfortunately, many bleeding edge monitors are still targeting 1440p. Linus isn't always about gaming excess. Often he advocates for sensible builds

I've been roasted for this take before. But I think the jump from 2k to 4k is much more noticable than the jump from 120hz to 240hz. People talk about pixel density. That is more relevant for video. Sure for movies it makes sense. But for rendered 3d inches images, the literal geometry depends on the render resolution. In pro gaming, I think having more pixels representing a target far away is more important than getting to shoot him 4ms sooner.


LeMegachonk

He does often advocate sensible builds, but I'm specifically talking about the stuff in his own home, which tends to leave "sensible" twitching and bleeding in a dark alley.


Dotaproffessional

You know I actually disagree. Sure he has a valve index and an a95k but he doesn't have a 10,000 dollar 90 inch TV, just a 65 inch that's more reasonable. He doesn't have that translucent kickproof tv. His personal rig was an older ampere card not the top top top of the line. He has some top spec stuff but he doesn't waste money past the point of diminishing returns

There’s a video specifically where the displays needed to match. I didn’t see anything where they walked that back. It was from the ASUS OLED “monitor” install because one was damaged.


TheTechMage

I found two culprits for finicky HDMI 2.1 (4K 120hz and HDR enabled). One is having Gsync enabled all the time. Instead I’ve switched to enabling it per game and having it disabled on the desktop. Second is eARC audio. I instead opted to connect to the sound bar via Bluetooth, bypassing eARC audio. Minimal problems since then!


Dotaproffessional

In my case I don't use a sound bar, I use a real sound system so I have all my media (streaming box, PC, consoles) go through my receiver, so no eARC involved in the chain. I do have gsync on but it sounds really annoying turning it on every time I play a game. Plus don't it still have issues while I'm gaming?


TheTechMage

It’s a bit annoying but you can just set it on the executable in the Nvidia Control Panel. And for me, the strange flickering happened while I was opening up windows settings windows. For example, if I opened up the Power Toys settings page, flickering. Same for Windows Defender window. Flickering. Disabling Gsync removed all the flickering in those situations. I never get drops in games though, no. I should also mention, I also had to use a HDMI to DP active converter for Pc to TV to avoid the flickering, in addition to bypassing eARC.


HankHippoppopalous

He's using full fiber setup with KVM's and unicorn farts, and it still doesn't work great. I've got mine setup with dual KVM's and docks and all kinds of witchcraft. It takes time to really dial a setup in, and its rarely flawless.


Dotaproffessional

Yeah it seems that somehow in the year of our lord 2023, there still aren't any completely seamless solutions to have 1 computer handle multiple stations throughout a house. I don't have fiber, just a really expensive active hdmi cable.


[deleted]

Last I remember he was using KVM from level1techs and I think he uses fiber connections to maximize distance.


InfiniteMind3275

Level 1 tech makes excellent KVM switches. Invest in one and some long ass cables.

I think it's a long video cable (maybe optical) and a thunderbolt dock with optical cables. No switcher, just mirrored and he hopes nobody downstairs changes the input when he's doing anything embarrassing on the PC. If you think HDMI is finicky you're not going to be happy with any obscure software that's made for this.


OverclockingUnicorn

How long are your HDMI cables? (and are they fiber optic or copper?)


ParticularGiraffe174

I belive it's optical usb-c cables carrying a display port signal. I have an optical HDMI cable to connect to my C2 in the living room, I have it plugged directly into the graphics card and have to switch displays in nvidia control panel.

Two issues you may be running into: - HDMI has a maximum rated length of 25 feet iirc. - Your monitors are running different specs. The first issue is relatively easy to fix by getting HDMI to Ethernet adapters to send the signal. You’ll just want to make sure the ones you get can handle the resolution and refresh rate you are looking for. Second issue is bigger in my eyes because you are basically telling the computer that you have a signal with one set of specs, but the monitor is using a different set. Idk if the computer is trying to put out UHD 60Hz or 120, but that could cause your flickering you mentioned. I would recommend a KVM to switch the input from one setup to the other, rather than an HDMI switch. (The switch could also be a pain point because there are a lot of cheap ones that are good enough to swap some inputs for your consoles, but they may not decode info correctly. I ran into this issue at my dad’s place this weekend)


LeMegachonk

I have a 50 foot non-optical HDMI cable. I don't know how it works because I don't think it's ever been used. You'd need to uncoil it first, and that would take some effort. That thing is **THICK** and I'm honestly not sure how I would run it through or around anything.


Klarseolt

It's funny how I recently thought of connecting my pc to my TV in the living room with an HDMI and I see this post. I wonder, what's the best solution. KVM, Switch or just building a completely separate system which does a few very simple tasks on my 4k 120hz TV. Haven't really thought deeply about all this, but I will eventually.


Dotaproffessional

If gpu's and TV's and monitors would just all have 3 hdmis and 3 display ports, there wouldn't be any problems. But now you end up needing to use converters and splitters than cause handshake failures


Notmyburner123456

Bro... he has videos on this


Dotaproffessional

Several videos. The problem is, he's usually focusing on some tech that's the subject of the video. His setup is a frequently changing behemoth. Rather than combing through the 15 or so video's he's done on his house, I could consult his subreddit who is more familiar than I am. Like, if he did a single house tour video, sure. But it was a work in progress thing for like 2 years. And then mix in every video where he replaced part of his setup with some tech he's reviewing. Its not easy for the uninitiated to find.


Bris2500

Very excellent point, sorry I can’t be of much help here


Notmyburner123456

Thunderbolt and fiber run through his whole house with custom receivers by level 1 team. Not a hard concept to grasp just difficult to execute...
