I recently purchased a LG OLED C2 TV, which supports 4k120Hz but only has HDMI 2.1 ports. I am aware of HDMI 2.1 being an issue on AMD, even though my GPU is Nvidia (RTX 3060Ti) I want to switch to AMD in the future, so I opted to invest in an AMD-friendly setup. I purchased the Cable Matters active DisplayPort -> HDMI 2.1 converter mentioned in this Reddit thread, which purportedly can do 4k120. However, when I change it from the default 4k60 modeline to 4k120, the TV shows a "no signal" message. In fact, to get 120Hz I need to drop the resolution down to 1440p.

Even though I'm not going for VRR (yet), I also tried flashing the VRR-enabled "Spyder" firmware just in case it fixes the refresh rate (it does not). I tested every DP port on the 3060Ti as well, with no changes. What might I be doing wrong?

Hi! I hope this post is on-topic enough. I've just moved into a flat in Germany and its thermostat has an incredibly loud clock ticking every second. My landlord allows me to replace it, so I looked for options and learned it uses a proprietary interface (Vaillant 7-8-9) and my only real option is from the brand Tado. I e-mailed them and confirmed their V3+ wired model is compatible... but costs 220€; way above my budget. However, if I set the site to Germany the price drops to 100€.

Before spending so much on a device (100€ is still a lot!), I'd love to check whether I can use it with Home Assistant. I recently installed it on a spare SBC and got the zbdongle-e working, ready to start connecting things. I found (cw: AI image) this blog post that says it works by having HA emulate Apple's HomeKit, does this mean it should work fine, regardless of the zbdongle-e? Should I be aware of any caveats to this approach, or to the Tado thermostat itself?

Thanks :)
