4k 60 hz is not listed, only 30hz

Fri Jun 28, 2019 7:58 am

I have a mini HDMI to HDMI cable that DOES support 60hz (https://www.amazon.com/dp/B009W9RXVO/re ... UTF8&psc=1)

But when I list out the resolution modes possible using tvservice, it does not show 60hz at all, only 30. I'm disappointed with this device. It also very barely plays 720p video on youtube, anything more is not good.

Please stop advertising it as a "desktop replacement". I have 4k

Probably best to sort out the problem you are seeing before slagging us off.

Assuming you monitor does actually support it (some don't )you need to enable 4kp60, either by using the Configuration utility from the preferences menu, or by editing config.txt and adding hdmi_enable_4k=1. Note that this will increase power consumption and therefor heat, so if 4kp30 works for you, then I would recommend using that. Note, 4kp60 only available on HDMI-0.

There is a bug in Chromium that we are currently investigating which is slowing down video playback. ONce that is fixed all should be a lot better.

i updated the packages and now it wont boot, goes blank after outputting the kernel messages. wonderful, thanks.
i have a 4gb rpi 4b and 4k monitor capable of 60hz.

How did you update the packages? Did you try enabling 4kp60 first?

I'm having a similar issue. I only can get [email protected] even though i have the correct cable and added hdmi_enable_4k=1 to my boot config.txt. It's hooked up to a Samsung 4k TV that can do [email protected]

Since I have a PS4 that does 4kp60 on the same TV that should mean the pi would as well?

One more thing to check, you must be using HDMI 0 to get 4kp60. Cannot remember the exact reason why, some weirdness in the HW clocks somewhere means HDMI 1 is limited to p30.

Thanks for the response but it's still a no go in hdmi 0. I tried 2 different cables but still the same result. I'll try another 4k tv tonight. Another thing to note is that I'm using a pi 3 micro usb power supply with a usb-c adapter on the end (I know it's a little underpowered). I've ordered the official one but still waiting on the mail. Could that be related?

I would not have thought so. Using HDMI 0, setting hdmi_enable_4k=1 in config.txt should be all you need to get it going. I've got a 4k Dell monitor at 4kp60 and a Dell monitor at 1920xx1200p59 (?) running in front of me right now, with just those settings.

In the general forum topic about the Pi 4, there's been discussion about the Pi not supporting YCbCr420 at 4K 60Hz (which unfortunately my SDR 4K TV uses at 4K 60Hz - I'm still waiting for my Pi 4 currently though).

Could this could be the issue?

Not sure. But my TV is SDR as well

Hi jamesh,
as I cant get [email protected] running, would you mind sharing your config.txt with me? I have just made a post here https://www.raspberrypi.org/forums/view ... 7#p1491293, and the display I'm using is - let me say - similiar to what you have in front of you (sorry, can't go into details on a public forum).

The config is entirely standard. Just with the hdmi_enable_4k=1 added.

Are you sure the device supports p60? You could dump the edid using tvservice, then used decode_edid to find out what the monitor says it supports.

yes, it does! It's just as usual 'error 60'!

So I'm having the same problem and tried all of this and it's not working.

However, when I boot into LibreELEC it defaults to 4k60Hz and works just fine, so I know the hardware/cabling/monitor settings are all working.

Either other suggestions? Or should I just wait it out since this is all so new.

If you have set hdmi_enable_4kp60=1 in config.txt and are using the HDMI0 port, then it should just work.

Hello Guys, I have done a little help for guys cannot switch to 4K 60Hz :

Don't forget to put your cable on HDMI at proximity of power plug not the other one.
Enjoy.

Tried it all again on a fresh install, no dice. Like I said though, LibreELEC boots right in to 4kp60 without changing anything.

Not sure what the problem is. I understand this is new and there’s a lot of work to be done so I’m not upset about it, still love the Pi, but it’s obviously still a problem for me.

I've been dealing with a similar (if not identical) issue with 4kp60.
My monitor is a Samsung U28E590. Samsung says HDMI2 can push 4kp60. I could not get 4kp60 from either my Pi42M (config.txt was correct) or my Windows 10 desktop, regardless of HDMI port. I switched my Win10 box to 2560x1440 @ 60Hz, and it worked fine. Then I switched back to 3840x2160, rebooted Win10, and [email protected] Looks great.
Later when I get time I'll try the same on my Pi4.
May be unique to my monitor, but I doubt it.

Update: did same with Pi4 and now it's running at 4kp60.
Seems to be monitor wonkiness and not the Pi4, at least in regard to my particular monitor.
YMMV.

Hi there! I baught myself a new pi 4 and want to have a 4k 60Hz output.

I am using hdmi port 0 with an amazon basics hdmi to mini-hdmi 2.0 cable.
Unfortunately is only shows 30Hz- on my TV and my monitor (both capable to do 60 Hz).

I have "hdmi_enable_4kp60=1" in my config.

Does anyone have a clue what coud be wrong?

My UHD Samsung TV is only supports 60Hz (basically HDMI 2.0) if the HDMI UHD color option is enabled on the HDMI port.

I have 2 HDMI-4k-60Hz screens (Monitor ande TV), I don't there is something wrong with them. I am trying a different cable today. I am gonig to report!
