Under your display settings in MadVR Control Center you wanna config manual refresh rate switch. It's a line of comma separated resolutions + frame rates you configure MadVR to be allowed to change to. If you use MadVR correctly these should always be the same resolution as your native display resolution.The whole point of MadVR is to leverage the extra horsepower of your GFX card to upscale your content to native display resolution. This means that using MadVR to downscale from 4K to 1080p is a waste, besides, MadVR will then use Cat-mul downscaling to process the 4K into 1080p. You're basically just forcing resources onto the gfx card to be spent on getting a worse image. The correct way to go about using MadVR with 4K content on a native 4K screen is to actually set up a profile that will disable all upscaling and image processing when watching native 4K content. This way you will just have MadVR render the 4K file without any extra resources for image scaling. I'm talking about upscaling chroma on a 4K image, which can be really heavy and also doing image processing on an image that is not being upscaled but is already 4K will hit the GPU hard for no reason - it's basically a waste.Basically you want everything below 4K to be upsclaled by MadVR and leave 4K untouched.Bottom line is: Using MadVR in a manner where you set it to downscale to anything but native display resolution is a waste and not worth the use of MadVR to begin with.You should only force MadVR into your native resolution, but then with different refresh rates so that MadVR is limited to only use 23,24,30,59,60 in 2160p.It is a hardware upscaler (THE hardware upscaler), after all. It's supposed to upscale your SD and HD content into higher resolutions, if you're not doing this, you shouldn't be using MadVR to begin with.In terms of the HDR 4K question, MadVR has a feature to "Pass HDR metadata to display" under the Display settings option in Control Panel. This way MadVR will not do anything to the HDR signals on the way to the TV. You can also have MadVR do it's own HDR treatment which is usually better or more correct than what your TV comes with. But that is entirely up to you.Just know that "What the director intended" is hardly achieved anyway since the displays are made to clip highlights according to their ramp up to 1000-2000 nits~ (LCD panels ofc, OLED is lower.) Where as the bluray you're watching can be mastered all the way up to 4000 nits. So the display will have to treat the nits to a ramp so it can "keep" a decent ramp of brightness. This means that every TV out there uses different settings depending on display and software and that MadVR might be able to do something better with the HDR than what your LG, Samsung, Sony... what ever display does out of the box. So.. Let MadVR passthrough the HDR metadata, or try to have MadVR treat it - see what you like the most. It's up to you.See ya!
