Monitor on DVI, AV system on HDMI

[mikeford]

I want audio only on the HDMI and video only on the DVI, but when I plug in my receiver and turn it on Win10 makes the doesn't have a display receiver the primary display with nothing on the DVI connected monitor (its secondary and I can move the mouse to it, but nothing useful comes up on it).

We don't have a big screen yet, and my ONLY HDMI input monitor isn't powering on as of today. Do I need a HDMI monitor all the time, or just to set up the DVI as primary?

Gigabyte B450 motherboard, Ryzen 5 2400G (tried with above results, now not planning to use onboard graphics), just added Radeon RX 460 and haven't seen any difference using its connections. Nothing I can see in the bios settings that is relevant.

Bonus question, is the 2400G enough CPU for the RX 460, or should I return it and get a 6 core Ryzen 7 2600 while I can?

Thanks

I'm not sure on your first one. I'd think it should be possible (to do just audio out HDMI, with DVI as the primary). I tried figuring out some way where it'd let you adjust that, but best option would be when just doing DVI to tell it to mirror or just Display 2 so that when you plug in the HDMI you'll be able to get back into settings and be able to set that as the primary (which seemingly you could set it not to output video to the HDMI, not sure if that would affect audio output or not).

On the second, not sure, as it'd depend on price (and no telling what the 3000 series might offer, so might be better to wait, but then you have to kinda wonder if your board will get updated to support the newer ones properly; I'd expect a Gigabyte 450 board to get updated). The 2600 would give you more longevity than the 2400G would, so if you decided in the future to upgrade the 460 it'd benefit you. I think there's already some games that benefit from the extra cores/threads too. So depends on cost, how long you expect to keep that system, and your upgrade tendencies (if you upgrade the whole system). Also if you have use for older system with integrated GPU (like for a NAS, router, or just simple web browsing box or something).
