The notes are based on the NanoKVM PCIe as that is what I wanted to set-up on a Windows 11 compatible PC that could be remotely managed for someone not savvy enough to do that themselves. They had an old Supermicro based PC with IPMI which kind of does IPKVM when using the embedded video hardware, but back when I wrote this early 2025 – the year Windows 10 would become end-of-life – it was:
- a nightmare to figure out which Supermicro mainboards were Windows 11 compatible
- remote IPMI tooling ¹ was a pain to get working (the most important one is IPMIView which requires Java and even with Java installed would have issues connecting to various generations of IPMI)
- newer KVM tooling has way better
- user experience than classic ones like IPMI and iDRAC
- features like for instance WireGuard support which makes for way less network configuration
- open source software (for at least NanoKVM I mention here, but also for Pi-KVM which has the drawback of also requiring a Raspberry Pi)
Since none of the modern remote KVM hardware tooling seems to be able to do passthrough video, the solution I researched for was to split the outgoing video signal (either Displayport or HDMI), then optionally convert Displayport to HDMI and finally route that HDMI into the remote KVM hardware.

After researching the below tweet, I found out that many LG monitors have this limitation on downstream ports, depending on how the upstream USB-C port is connected:
Their manuals phrase it like this:
- When the USB C-C cable is connected between Upstream port of monitor and Host PC, the Downstream port of
monitor support USB 2.0 device.
- When the USB C-A cable is connected between Upstream port of monitor and Host PC, the Downstream port of
monitor support USB 3.0 device.
However, Host PC must support USB 3.0 function.
This means that in USB C-C land (for which Apple was basically a driving force, but nowadays many laptops only have USB-C connections) your monitor downstream ports are limited to USB 2.0.
If I read the various comments correctly, the additional limitation is that in the USB C-C case, the downstream ports are non-powered.
Which means I will avoid LG monitors at all cost.
Tweet: [Wayback/Archive] anna (arar) meow 𓃠 on X: “i have this monitor connected to my mac with a single USB C-C cable. why can’t i have USB 3.0 speeds on the downstream ports??? why does it work with the USB C-A cable?? is there a way around it? or is there just not enough bandwith for both video and these silly ports?”

Some interesting tidbits to reset a UE55MU6100 or similar TV from [Wayback/Archive.is] We have a 2 week old Samsung mu6100 55″ tv which up until an:
- Soft reset: Unplug the TV from the wall, hold down the power button on the rear of the TV for 10 seconds, then plug it back in and turn it on.
- The power button is on the backside : it’s the middle part of the 4-arrow-button.
- Factory reset: power off the TV, and hold down up, down and power buttons together for about 10 seconds, then releasing them when the Samsung Logo shows up.
- Reset to engineer menu: put the TV in standby, then press the info, menu, mute and power buttons on the remote

I’ve got a Samsung (Smart) TV connected to a 2nd Generation Chromecast and HDMI-CEC/Anynet+ was working fine turning on the screen when it needed to.
…
TV wouldn’t activate on demand. Went through a bunch of options reseting the HDMI-CEC/Anynet+ connections via the TV menus. Tried the power button on the TV remote to cycle the TV. I think I power cycled the Chromecast.
…
I finally tried switching off/on the power strip that everything was connected to did it return to life.

Oh nice: [Wayback/Archive.is] Samsung can remotely disable their TVs worldwide using TV Block.
This means:
Disconnected, any apps needing internet connection won’t run.
Those apps usually work more reliable on an Apple TV or similar device that plays over HDMI anyway.
In addition, it will also prevent Samsung to show adds on your TV.
So disconnecting it is a win-win-win situation.
Note: you could already block apps and adds, see:
Maybe those blocks also block blocking.

I had a problem similar to [Archive.is] MX613ST Color space conversion issue (detects YUV instead of RGB) – Google Product Forums.
In my case I had a Chromecast 1st generation connected to a [WayBack] Harman Kardon BDS 580, which was hooked up to a [WayBack] Samsung MU6100 TV.
Everything, especially the white and grey areas, had a greenish tint over it, and I think there was also a purple mismatch.
I think it has to do with YUV versus RGB, similar to [WayBack] Force RGB Color Space over HDMI? – Apple Community.
Though I did not notice that with an Apple TV 4th generation (which you can switch between YCbCr/RGB-High/RGB-Low) hooked up to the same BDS 580.
The solution: plug the Chromecast in the TV, then the ARC (Audio Return Channel) will automatically route the audio to the BDS 580.

Since the Display on the frontside is labeled as “Philips Brilliance 240B”, finding the actual supported maximum resolution took an additional step resulting in these specs: [WayBack] Specifications of the LCD monitor with Ergo base, USB, Audio 240B1CB/75 | Philips
This is what I needed from it:
Philips Brilliance 240B max resolution: 1920 x 1200 pixels at 24 bit via either of the inputs
-
VGA (Analog )
-
DVI-D (digital, HDCP)

Experience from a friend:
The cause is that the Samsung only does 60Hz on DisplayPort because they do not support HDMI 2.0.
