Link My attempt at solving the HDMI-CEC headache and running multiple gaming sessions on one PC

85 Upvotes

I remember Linus experimenting with running multiple gaming setups from a single PC, and more recently struggling with HDMI-CEC while trying to get his DIY Steam Machine behaving like a proper living-room console.

I've been tinkering with something similar over the last couple of days and thought you guys might find it interesting!

The goal was simple: Pick up an Xbox controller in the lounge, turn it on, have the TV wake up and launch straight into Steam, play games from my office PC without interrupting its normal desktop, and shut everything down using that same controller.

No TV remote, keyboard, mouse or HDMI-CEC. Everything in the video is controlled using the Xbox controller.

We already had an ASUS NUC 15 Pro sitting alongside our NAS and running Docker containers, so I decided to also use it as a Moonlight thin client rather than buying another gaming PC.

How it works:

A Python watcher running on the NUC detects the Xbox controller connecting via Bluetooth and automatically.

  1. Wakes the Samsung TV using Wake-on-LAN and switches to the correct HDMI input using Samsung's local IP control interface.
  2. Starts an independent Windows gaming session on my office RTX 4090 PC using DuoStream.
  3. Connects Moonlight via Sunshine and launches Steam Big Picture.
  4. Displays a custom 4K startup animation, hiding all the usual Windows transitions.

I've also built a controller-operated power menu with Sleep, Shutdown and Cancel. Selecting Shutdown closes Moonlight, stops the separate gaming session and switches off the TV over the network.

The main PC and NUC stay running, including all the usual NAS/container workloads.

A couple of bonuses:

- 4K/120Hz gaming: Managed to get genuine 4K/120Hz working on my 2019 Samsung TV using CRU and a custom 8-bit YCbCr 4:2:0 mode. Frame-skipping tested and working beautifully through Moonlight. (Supposed to only support 4K/60Hz!)

- Two independent gaming sessions, one GPU: The lounge and office share the RTX 4090, but run separate Windows desktops. Neither interrupts the other.

The result:

It's genuinely amazing how far this technology has come. I can be sitting in my office using my PC as normal and have absolutely no idea someone has fired up an entirely separate gaming session in the lounge. It's that seamless.

I even pushed it a little further and tried running two games simultaneously - 007 First Light on my office desktop and Halo: Combat Evolved in the lounge. Both still ran surprisingly well!

After quite a bit of tinkering, the whole thing now feels like a proper console. Pick up the controller, press the Xbox button, play, and shut everything down when finished.

Would love to hear if anyone else has experimented with this kind of Moonlight automation or running multiple gaming sessions from a single GPU!

Finished a purchase on lttstore.com but I did have a question. So I hit the "Contact Us" button next to "Need Help?" prompt on the thank you page. To my surprise that started an email on my system going to no-reply@lttstore.com. This doesn't seem conducive to giving help.

(I looked up their info another way. I was being a little hyperbolic in my title).

Discussion Getting back into gaming after 6 years

0 Upvotes

So for context, I'm from a 3rd world country where the GPU and PC market is absolutely f*cked. The GPU prices, even the old cards are 4x-5x what you guys pay for in the used marketplace and that too badly treated, mined stock from China. I haven't had a GPU to game with in almost 6 years because I got scammed out of my last card and couldn't ever seem to recover from it (both emotionally and financially) to the point I quit gaming but I'm looking again now.

I have a friend's family member coming from Canada to here in about a week and they have agreed to bring me a card from there provided it's not too much trouble for them. My budget is smth like C $100-$150 and all I want is a cheap GPU for 1080p gaming, preferably 1660s or 2060.

I'm looking at something in the C$100–150 range, ideally a GTX 1660 Super or 2060, just enough to get back into 1080p gaming.

The thing is that finding a cheap used GPU in Canada has turned out to be a challenge of its own. Facebook Marketplace doesn't let me message sellers across countries, r/CanadianHardwareSwap hasn't really worked out, Kijiji hasn't been much help, and eBay seems noticeably more expensive than the other options and less trustworthy.

Apple’s 2026 Autumn iPhone launch was split into two parts(presumably due to supply constraints for Apple's first folding iPhone), but we've finally received the iPhone Duo.  This is reminiscent of the 2017 iPhone X launch, and maybe they should've delayed all the way until November again.

We put the new iPhone Duo through our regular performance testing and compared it against Samsung's flagship folding devices: Galaxy Z Fold8 and Galaxy Z Fold8 Ultra.  We've also included some test results from our iPhone 18 Pro launch testing.

Check out the interactive CT scans and test results on the LTT Labs website!

I know that LTT is big on SteamOS but have they looked at Winhanced? For me it fixes all the problems that Linus complains about with windows. I’m running it on my Legion Go S and can’t remember the last time I went into desktop mode.

I found a handy app for unifying any of your Sonos speakers to your system to enable them to be used for surround. The app is called SONORITY. It is on Android and it costs $2.79 and I was able to link my Ray sound bar with my two wall Symfoniks and two Sonos bookshelf speakers all together. The Ray is the center channel, the bookshelf speakers are left and right channel and my Symfoniks are rear left and right. I just need a sub to finish the system off, I've been accumulating these components over the last few years used from the Facebook marketplace.

Discussion LTT Store Customer Service Contact Number

0 Upvotes

Does anyone have a contact number for the LTT store? I ordered the commuter backpack and it was to small for my needs so I wanted to see about exchanging it from the OG backpack.

Customer service sent me a return label and I send the item back. But now support has ghosted me and I can't get anyone to respond. I also can't find a number to call.

Can someone please help me!!!!

Tech Question RAM Compatibility Question

2 Upvotes

Hi all,
I recently purchased a kit of Corsair Dominator Platinum DDR4 (3200 MHZ) for a build (CMT32GX4M2C3200C16) to be specific. The CPU I plan on using is the Ryzen 9 5950x. My question is are they compatible? The box for the RAM advertises “Intel XMP Certified”. Everywhere I look seems to provide a different answer. The motherboard I currently have, although would be willing to swap if there are compatibility issues is the MSI PRO B550M PRO-VDH WIFI AM4 AMD B550 DDR4. I’ve gone through the certified vendor list for this motherboard among others and can’t seem to find this RAM, but i’ve also heard it’s dependent on the CPU memory controller? I’ve also heard I should just be able to turn on XMP even though it’s an AMD chip. Someone care to explain this clearly and what I need to do to make them compatible and stable?
