Trouble Achieving 4K@60Hz with MSI GTX 970 on TV

[dennis15510]

Hello everyone,

I'm currently facing an issue with connecting my computer to my TV using my MSI GTX 970. Unfortunately, I'm unable to achieve a 4K resolution at 60Hz. My TV supports HDMI 2.0 ports (the PS5 works flawlessly in this regard). I've also invested in a new cable, the third one, specifically rated for 4K@60Hz, but the problem persists.

Here are the key details:

• Graphics Card: MSI GTX 970
• TV: Panasonic
• HDMI Cable: multiple HDMI cables 4k @ 60
• Operating System: Windows 11 64 bit
• System Specs: PSU 750 watts
• Software Running: No software is running when this problem is occurring
• Error Messages: no errors are popping up

Despite my TV supporting 4K@30Hz, I'm struggling to figure out what I might be doing wrong to achieve 4K@60Hz. If anyone has encountered a similar issue or has suggestions on what steps I can take to resolve this problem, your help would be greatly appreciated.

Thank you in advance!

Do neither in windows directly nor in the Nvidia control panel you can select 4k60? Only 4k30? Anything else with 60hz possible (1080p60)?

Are you trying 4096x2160 or 3840x2160?

Need the specific TV model number to look at the manual and specifications. Not all TVs support 4K@60Hz and if they do, the exact settings to get 4K@60Hz can vary substantially.

Hi everybody!

 

thank you for thinking with me!

 

@FloRolf when I select 4k 60hz in the nividia control panel then the tv doesn’t output a signal anymore. Only when i select 4k 30hz (or a lower resolution). 
 

@jaslion 3840x2160. 
 

@problemsolver the tv does in fact support 4k 60hz. For example my ps5 works on this resolution and refresh rate. 
But of course you can check it! 
it’s a panasonic 55cx700

 

If you guys have any other question let me know!

Okay, I wanted to verify that there wasn't something funky going on with color depth, but the owners manual doesn't really give much in the way of specs.

 

• Make sure you've updated to the latest Nvidia driver
• Is your TV up-to-date?
• Does the 60Hz option not appear in Nvidia Control panel? Or does it appear, but when you click Apply, it doesn't work and the screen goes black and reverts to 4K@30Hz?
• Also, as an aside, you won't be able to stream 4K Netflix even if you get 4K working @ 60Hz.

[dennis15510]

@problemsolver hi thanks for replying again!

yes the drivers are up to date! I also tried to uninstall them once to see if that would fix the problem but no sadly. 
(with that special uninstaller software). 
 

tv is up to date!

The 60hz option is there but when I select the option and apply it the screen goes black. 
 

I’m aware that I can not stream netflix in 4k.

What happens when you select 1080p at 60hz? Does that work? Are you using the same HDMI Port as the PS5 for testing?

[dennis15510]

@FloRolf yes 1080 60hertz does work. 
I am using the HDMI that I usually use for my PS5 for testing purposes. 

[leclod]

Seems you've got 2 HDMI 2.0 and one 1.4. Did you catch the wrong one ? (got it from the french website Les Numeriques)

@leclod sadly no. Because i'm testing it in the same hdmi port of my ps5. The ps5 is displaying 4k @ 60hz.

I'd still try another TV hdmi port

[dennis15510]

@leclod I tried all of them at this point, sadly.

[leclod]

Can you try another TV ?

[dennis15510]

@leclod I wish, sadly I don't have another 4k monitor/tv laying around. 

[leclod]

Where do you try to set the 60Hz, in windows or in the NVidia pannel ? I guess it results in the same

But did you try the other ?

Edited December 17, 2023 by leclod

[dennis15510]

@leclod I always used the nvidia one, but now I tried the windows one. Same result sadly.

[leclod]

Did you set your tv in pc mode ? I don't know if this is important

I know I did, the HDMI port as PC input

Edited December 17, 2023 by leclod

[dennis15510]

@leclod I just looked at all the settings but I don't see anything like tv mode. I did see something like graphics mode, didn't really change anything and I coudn't select tv/pc. Just things like picture, game, etc.

I mean set the HDMI port as a pc input

[dennis15510]

@leclod you mean in the Nvidia control panel? That's not possible, I only have the option for "Ultra HD, HD, SD" not "PC"

no, in the TV,

I did set the HDMI port as a PC input, I believe it has to do with Chroma Subsampling: 4:4:4 vs 4:2:2 vs 4:2:0

[dennis15510]

@leclod I checked every setting but I don't see anything about Chroma sybsampling but I did find two weird settings:

 

HDCP-settings > I can choose between auto, 2.2, 1.4. Nothing changes when i play with these settings

HDMi automatic configure > I can choose between Modus 2 and Modus 1.

When I change it to modus 1 I will get an image but it's not really 4k 60 hertz but 720. Really weird. 

[dennis15510]

I fixed it by choosing HDMI automatic configure modus 1 + not believing what the resolution checker website was reporting because that was based on the windows 11 scaling and not the actually resolution.
