i know what fit to screen does unlike you.

It's older but it applies today also.

do you get 4:4:4 yes no?
do you even want 1:1 pixel mapping on this 100% 3840x2160 screen?
do you even want 4:4:4?
and you you know why you are losing some picture modes...
because it is entering PC mode.

100% 3840x2160 screen because you say so?You gave me link and I gave you too officially.
Chroma.png fails there too.....
For the last 2 sentences:I've read it somewhere too that some picture modes get disabled but what If they fixed it with the updates they've made?
To enable PC mode you just rename HDMI 1 and and put UHD color on.That's all for the TV settings.

I get 4:2:2 with Chroma.png and I've followed the instructions for both TV and GPU.

2010 and no just read the Manuel.

so paint works now?

edit:
https://abload.de/img/amdwbsql.png and you did the basic yeah?

do you really want to now why that TV is 3840x2160.
because the specs say it
because it is overscanning with a 4096x2160 input signal only left and right of cause.
because it is not over scanning with a input signal 3840x2160. not talking about video files
because the manual says that 3840x2160@60 hz is the recommended and optimal setting for a PC.
because fit to screen is made to move images larger than the screen on the screen. if fit to screen would mean 1:1 pixel mapping and the screen is 4096x2160 it would add black bars on a 3840x2160 input signal(not file!).

amd is reporting the wrong recommend resolution with UHD screens i can reproduce this here right now.

[Damien147]

What changed is the name from screen fit to screen to fit.
No vanished pixel format bug,I was talking about different thing but I am not 100% sure.What I know is that ''this guy'' sees 4:4:4 with local lan and waiting for a response with HDMI.
I can't put 3840x2160 like that,with windows happens what you said earlier.It doesn't change.Radeon settings don't have anything to change resolution for some reason.I forced 3840x2160 with Madvrs display modes to check 3840x2160.


edit:yes,I am like that in your edit pic

[huhn]

change the resolution see if the TV reports 3840x2160 if not try this.

go to display settings -> set "change size of text..." to 100%
cahnge to 3840x2160 this should force it. you can of cause change this back to what do i know 200% (1080p sized icons) after the resolution change.

and disable GPU scaling.

and yes crimson is the biggest downgrade in the history of drivers.

huhn, Ive tested 4K again tonight and confirmed that I cant get RGB @ 4K 60Hz with my GTX1080 card, all I have in the drop-down box is YCbCr, this is why my image is washed out.

I can always get RGB @ 60Hz when Im on 1080p>1080p as thats the way I always run it.

I tested 24Hz @4K and RGB appears in the drop-down box and it looks fantastic, but I want to use 60Hz @4K.

Why when you set the 1080 card to 4K @ 60Hz it doesnt allow RGB in the dropdown box, is that normal?

with YCbCr output you have to set madVR to 0-255.

the spec say it is clearly 18 gbit/s

the 1080 can do it for sure there is no question.
so how is the projector cabled?
please list HDMI repeater, AVR or other stuff that may or may not be in use and cable lengths.
and check if hey are HDMI 2.0.
there are ways to work around the AVR using an iGPU for example or an displayport -> HDMI cable

[Damien147]

@hunh

These are already done sideways and I get a big fail.


Edit:another thread http://www.tomshardware.co.uk/forum/...60hz-hdmi.html

[huhn]

someone is reporting a bug in samsung TVs:

Step 2: "UHD Color" option cycling.



Once you have the latest drivers installed and the display is setup correctly you need to press the menu button on the remote and navigate to the “UHD Color” setting on your TV for the input the computer is plugged into. The computer must still be on.
This setting needs to be cycled OFF, then back ON for the input the computer is connected to. Doing this requires the TV to restart each time.
Once you cycle the “UHD Color” option back ON the TV should now show the correct resolution on the TV’s "Info" button on screen display (3840×2160 / 60p). The display should also now correctly be displaying full 4:4:4 chroma subsampling as the CAC-1070 and CAC-1170 are meant to be able to do.
Keep in mind, after cycling the the UHD Color option OFF then back ON, the correct resolution may still not be displayed (and it will be putting out 4:2:2 chroma subsampling). If this is the case you will need to cycle the "UHD Color" option OFF and ON again, possibly several times until you get the desired result.
Also important to note that once you turn the TV off then go back and turn it on later the TV will have reverted to it’s previous state and you will have to jump through the “UHD Color” OFF-ON cycling hoop again to get back to your desired result.
Please be aware that any resolution changes/refreshes will kick the TV out of the correct mode (3840x2160 @60hz with 4:4:4 chroma) and it will revert back to the incorrect 4:2:2 mode with 4069x2180 displayed on the TV's "Info" button on screen display. This means any program that changes resolution in any way (for instance starting a game up) will knock the TV back into 4:2:2 mode. Then you must cycle the "UHD Color" setting again to get back to 4:4:4. When you cycle UHD Color back on it sometimes takes quite a while for windows to scale and refresh your desktop making this tedious and inconvenient.
This workaround method IS NOT a viable solution for people that will be going in and out of programs that change/refresh the resolution such as gamers as you will constantly be messing with the display to get the correct output.

i never had these problem on my panasonic.

but my RX 480 stayed at 3860x2160.
but as you can see he get's the rubbish 4096x2160 default resolution bug too.

i had a way bigger problem than this with HDMI handshake issues so i gave up after the 3rd card and got a 1060 that works perfectly.

I still really want to get RGB rather than YCbCr with 0-255 dont I, isnt it meant to be better?

The PC is direct to my Lumagen Pro (not the new 18 gbit/s card) all cables are short to the projector then to my McIntosh pre pro MX160, audio only. I now think the problem might be as I dont have the add on 18 gbit/s replacement from Lumagen, is that right?

Is there a work round without getting the card from Lumagen since I only want to upscale BDs @60Hz 4K?

The upscaling is all working correctly without dropped frames as I see that in the menu, it does look fantastic when Im on 24Hz with RGB, but I cant run this way @ 60Hz, without RGB its washed out

[huhn]

without removing the Lumagen Pro or upgrading the card there is no way for RGB@60 hz.

and yes RGB is preferred so it is technically possible to send the madVR image untouched.

if the Lumagen Pro is used for calibration think about a madVR 3D LUT.

in my book everything that touches the image created by madVR is a bad thing and is just degrading image quality.

but this is just me.

[70MM]

Yes I would rather not use 4K if I cant get RGB from the Pro @ 60Hz.
I dont want anything to touch the madvr settings so Im with you!
Looks like I will have to invest in another upgrade, the 18 from Lumagen.
It never stops.....

@hunh

Long story short:
Oh god...I've wasted yours and peoples energy with these bugs.Gave me wrong conclusions.SORRY guys.You are right about resolution and you are correct about the bug in TVs,it's 3840x2160.Finally! http://imgur.com/a/tZhr9 (ignore the *hitty quality).Now that I got 4:4:4 I get bad colors because of these picture modes that get disabled with PC mode..... <----edit:solved.(Found an icc profile and settings)
Just for the history about fit to screen skip this video to 1:45 https://www.youtube.com/watch?v=zsnPBuI7xIU .But it doesn't matter in PC mode because it gets disabled too.




edit:maximum reported resolution my @ss...http://imgur.com/a/vGU26 ...and still wonder where settings for resolution,underscan,overscan and whatever are.

[rebel_rebel]

Hello!

I hope you can help me.

I am looking for the best picture settings using madVR.

I am using a dell T20 and a GTX 1050 Ti graphic card.

My Display is a Dell U2515H 2560 x 1440 @60hz.

I am watching 24p movies on my computer using MPC-HC.

Settings i am using right now are attached.

[pirlouy]

huhn too stronk of cau...course ! :-)
Always believe huhn.

Are you outputting in 8 bits?

Yes 8bit, thats all it shows.

Thanks for the info. For now I downgraded my drivers to make sure it'll work this weekend: Projector, Popcorn, Action!

huhn can you explain to me why RGB is preferred if one only ever uses ripped BDs please?

Your screen is physically RGB. (let's see if I got it right)
