I'm experiencing a peculiar problem where connecting a TV causes two-thirds of my monitors to lose input and display black, even when the TV itself is off. This issue doesn't occur on Linux with all displays working properly. I have three monitors: two 2K 170Hz, one 1080p 60Hz, and a 4K 120Hz TV. I've tried DDU, reinstalling drivers, but it's still frustrating. The main concern is that the TV affects my monitors even when they're powered down. What should I do to resolve this?

You're referring to turning off devices in standby mode. TVs need the power cord unplugged to shut down properly. With multiple monitors, managing them can be challenging, especially with a smart TV adding complexity. Have you experimented with changing GPU outputs? If the TV is set as the main device, it may cause problems in Windows or with the NVIDIA driver. You'd want it to be the last one so you can safely disconnect it. I've only worked with up to three devices and a non-modern TV, so my insights are limited here. Linux might have its own issues too, but the driver setup likely differs. The hardware itself should function normally—what's disrupting the software?

Mhm. In standby. And yes, LG C1. If I had a simple TV with those settings I’d be happy. Sadly, such TVs are rare these days. Only one HDMI port on the GPU means it’s not much of an option. Also, using the TV as a secondary display and a monitor as the main one is tricky since they’re in different parts of the room. It makes more sense to keep the monitor as the primary screen. This really confuses me. If everything worked equally well on both Manjaro Linux and Windows, I’d be fine. The hardware limitation is the issue. But I didn’t see anyone suggesting the problem lies with Windows software. That Linux version can handle 32k x 32k while Windows can only do 16k x 16k according to Nvidia’s Quadro info—back when they were still called Quadro. It’s making me think about switching entirely to Linux, but then I’d have to worry that virtualizing and routing the GPU through Windows might just lead to similar complications with more variables.

It seems the main challenges stem from driver restrictions that hinder performance. Linux appears to function more smoothly in modern situations. For simpler displays, a monitor could suffice since the box handles most tasks and the TV merely outputs signals. Current market options for quality TVs are limited, so once my old 42-inch Toshiba is replaced, it will likely be swapped for a monitor.

55-inch display. I prefer it for lounging while gaming, especially with an OLED screen which is a big plus for me. It seems there isn't a perfect alternative since it works like a stand-in for my console—perfect for sitting on the couch and playing with a controller.

Checking if the TV settings might affect the connection. It could depend on the PC's configuration for the TV.

I'm not familiar with anything like that, but I'll investigate further.
