Yes thanks, but the hdrVideoPeak is a parameter to set profile rules, what I mean is that madVR doesn't inform in the OSD about the selected value. So if everything is as you say it's easy to deduce, but as madhi says that the latest buids completely ignore the metadata, there is no way of knowing what value they are using.

On the tone map value in the OSD, if that's its meaning then it should be equal to the measured frame. I'm thinking that it's different because it's a rolling average.

If dynamic tone mapping is involved, the measured frame peak is always the active MaxCLL.

The magenta 4:4:4 is very obvious while this is just random color detail you have to analyze. I don't understand why it is being linked as a way to test for chroma subsampling.

Honestly, I prefer the simple images, e.g. test2 from the Chroma section of this post, it's more straightforward to see (with an image viewer/browser) whether you get 4:4:4 or not. And if it isn't then does it matter what is?

Alright guys, please don't be mad at me if this is really pleb questions, but I just got a 4k tv, a vizio e series 43" E43-F1, I have a few questions about this. The first thing is the correct setting in nvidia control panel. I set it to 60Hz, it automatically switches to ycbcr, I can't do RGB with it. I fixed the stuttering for the most part by turning off the Windows HDR, but when I play movies I'm still getting 93 to 97% from my gpu, it's a 1660ti. I want to get that down, put correct settings in Nvidia control panel. Then I would like to know how should I go about calibrating this television. Should I just try and calibrate to HDR or HDR and SD both when doing so? I know this is a madVR thread, but all of these questions are mainly for viewing with madVR. Please help

Hi, you can only do 8bit 444 full RGB, you must have set it to 12 bit.

Never use windows HDR, turn this off and leave it that way, MADVR uses NVIDA HDR API and will turn HDR for you.

Make sure you use full screen exclusing in MADVR.


If you are a total noob dont mess with the calibrating settings on your TV, for more advice on this see if there is a forum for your TV specifically on AVS

I'm a noob with HDR calibration. I had 1080 calibration down great, looked great. I am just trying to figure out all of these settings. When going to 60Hz, the only option there is ycbcr 4.2.2 at 8 bits. There isn't anything else.

current HDMI standards only allow 8 bit @ 60hz with 4k, the reason its dropping to 422 when you set your desktop at 60hz is that you must have set you grahics card to 12 bit, check again.

You can get 60hz in 4k but only at 23/24kz, you have a lot of reading to do this i'm afraid, there are a lot of pitfalls with NVIDIA cards surround bits, resolutions and drivers.

start here.

I'm actually worried that it might be the HDMI cable I'm using. It doesn't anywhere on the page about 2.0. It's a vizio cable and just says it play 4k. I'm also wondering if this is what's pushing my gpu to 94% and above. I mean I got the 1660ti to compensate for the 4k upgrade, but man, it's a huge spike in gpu usage. I can't even watch this at 94% usage.

it will not put load on your card that's not how cables work.

you need computer picture mode and UHD deep color to make 4.4:4 work on these TVs.
be aware that this TV needs "film mode" for 24p you may don't have access to it in PC mode.

I tried computer mode, didn't change anything and film mode was already on.

ok, drop into 23hz and switch to 444 full RGB, does it show 8 bit or 12bit?

if it shows 12 bit drop to 8 bit and then change to 60hz

Update 10/24/2018: We've received a few reports that the 43" model does not properly display chroma 4:4:4.
they may have a cheaped out yet again.
https://www.rtings.com/tv/reviews/vizio/e-series-2018

Checked again, at 23Hz, all options are there at 8 bit, switching to 60Hz, only ycbcr 4.2.2 comes up. There is no option to change to anything else. There is no full deep color on this model. It doesn't support WCG. I got this because of all the 43" tv's this one got the best rating on multiple sites.

this is usually not tested and doesn't matter for most user.
to fix your GPU load i need a screen of your OSD.

So I don't know what the deal is. I was able to take screenshots before, but it's giving me a black page now and the rendering times are outrageous. I can't believe it's going this high from a 1080 to 4k. I was getting about 21 to about 53ms now?!

Do you have FSE enabled? I think this prevents it, but I may be wrong. But you can also post a picture taken with a camera.

This year's model can support 4k @ 60 Hz @ 4:2:2 or 4:4:4 color on all ports, but it works only when Full UHD Color is enabled for that port.

4k @ 60Hz @ 4:4:4 + HDR is also supported.
