Can't get 4k@60hz work anymore

Hello!

I switched OS from Windows 10 last week to Manjaro, up until couple of days ago I had no problems with my new OS, suddenly my tv reseted settings to no support on HDMI 2.0 and when I switched it back on. I switched back to 60 hz my TV went dark. Then I thought the problem was my TV so i reseted settings and all, but still no go.

Then I tried to boot on to Windows and see if it works there, and funny enough it does.

As you can see the option is there for me, but when i choose it my tv goes dark.

Could someone maybe point me in the right direction here as I have no idea what to do. This was working properly before so maybe I've done something wrong, I just cant figure out what.

Sorry if it's not the proper way to ask this question.

Thanks in advance for any help and please remember I'm not expirienced in Linux so maybe it's something simple I missed here. Oh and my GPU is Geforce gtx 960 and drivers 440.82.

Is it really so that no one can help me with this problem?

Hello and welcome to Manjaro!

To be able to understand your situation better we need more information on the hardware and software you use. Please provide the output of

inxi --full --verbosity=7 --filter --no-host

and format it as described in this post.

You could try to set the resolution manually for testing purposes with

xrandr --output HDMI-1 --mode 3840x2160 --rate 60

as lined out in the Arch Wiki

xrandr --output HDMI-1 --mode 3840x2160 --rate 60

I have tried this method at results into my tv going black screen and no signal same as if I do it from Nvidia X Server Setting

Thank you for helping me ! :slight_smile:

Could you explain this part of your question? I'm not really sure what you mean. What exactly happened to your TV? What did you switch back on? Does your TV work with 30Hz on 4K?
Do you have another source that can display 4K on this TV?

Hello,

I'll try to explain this best as i can, one day my tv had reseted it's settings to default, which is hdmi 2.0 off when I switched it back on and tried to change my refresh rate to 60 hz from nvidia settings in Manjaro. This resulted in my tv going dark and and saying no signal.

Before this setting reset from my tv I had 4k 60hz working fine on Manjaro too.

I'm dual booting windows 10 and over there the 4k 60 hz works fine. Also yes 30hz works fine on manjaro too just 50 and 60hz aren't working. Also on PS4 4k 60hz works.

Your TV is connected via HDMI, right? Your Monitor is connected via DVI, correct?

The other way around, Tv is via DVI.

Are you really, really sure?

DVI doesn't support 4K60 https://en.wikipedia.org/wiki/Digital_Visual_Interface#Digital

Please check your cables and confirm that your TV is connected via DVI.

It is a connected via DVI to my gpu but on my TV it's HDMI

You may want to explain this a little more.

Ok so here goes :smiley: It's a cable which is DVI on the other end and HDMI on the other.

On my pc it's connected into the DVI port and on my tv it's connected into HDMI port.

I guess you could call it either adapter or just HDMI-DVI cable, but I dont think the issue is the cable because this works on Windows correct?

How do you know that it is 4K60 under windows? Why don't you use a regular HDMI 2.0 cable?

Could you use your monitor HDMI cable to connect your TV and look whether that works?

Well, when I choose it from my nvidia control panel on windows my tv displays message like 2160p@60hz same as it does on Manjaro, expect on here the screen goes dark. And as I said before this issue wasnt on when I had just installed Manjaro.

I dont have HDMI cable that is long enough for this purpose

This is an edge case not within the specifications. I don't know what happened to your TV and I don't know how to solve this. I guess Linux works within the spec and only some not documented Nvidia wizardry is able to make this happen.

If you really want to drive your TV properly you should invest into a long enough HDMI 2.0 cable.

Ok :smiley:, thanks anyways for trying.
