still cant setup resolutions over 165mhz in switchresx after patch about mac-pixel-clock-patch-v2 HOT 22 CLOSED

Try if the nvidia patch works :)
For nvidia you need both

from mac-pixel-clock-patch-v2.

Floris, thanks, already installed NVIDIA patch:
MacBook-Pro:mac-pixel-clock-patch-V2-master igoralferov$ ./NVIDIA-patcher.command patch v2
SIP looks to be disabled, all good!
Keep SIP disabled, if enabled again SIP prevent the Nvidia Driver from loading
Patching NVDAGK100Hal with patch version 2
The code of the driver has changed, the patch was probbably succesfull
MacBook-Pro:mac-pixel-clock-patch-V2-master igoralferov$

But no success:

Also I installed nvidia web driver, but switching on that driver also dont help.

I can look into it a bit later, and in a few hours

from mac-pixel-clock-patch-v2.

Thank you! Tell me if you need some additional info

from mac-pixel-clock-patch-v2.

Okay let's start at the beginning:
Did this patch or the previous version ever work?
This patch does not support Nvidia WEB driver.. if i have time i'll add it!
What kind of cable do you use? any adapters?
What kind of connection does your display support? (HDMI1.4/2.0, DP1.1/1.2, DVI)

That is usefull information to have to solve this problem :)

from mac-pixel-clock-patch-v2.

This is the first time I'm trying to set up connection to the TV (Sony x9005b) from my Mac. I have tried previous patch but with no luck too. TV should support hdmi 2.0, at least it is said in the Tv review. I use techlink Iwires cable to connect Mac Mini DisplayPort to TV HDMI port ( http://www.techlink.uk.com/products/wires_cables/iwires/iwires_mini_displayport_plug_to_hdmi_plug ). It should support 4K as I understand.

from mac-pixel-clock-patch-v2.

TV should be fine cable should be fine, can you see if the drivers are loaded?
Open "System Information.app" scroll down to the software part and select extensions, let it load for 5/20 sec, then sort on "obtain from" you should see a the nvidia driver as unknown, click it and see if it is loaded properly.

Ok, it shows me this info:

Is it ok?

from mac-pixel-clock-patch-v2.

Maybe Kext signature validation error code -67061 looks like a problem?

from mac-pixel-clock-patch-v2.

Nope that looks right, that error is expected, because we change the file the code signature is invalid.. The file is loaded. Can you download an app that forces dedicated graphics gfx.io can do that.

from mac-pixel-clock-patch-v2.

It should work on the machine because it has dedicated graphics, but my 2013 MacBook does not play nice with 4k.. But my 2011 Mac mini does fine..

from mac-pixel-clock-patch-v2.

I have chosen Discrete only in gfx.io.
What I see in switchresx is that I can set resolutions with > 165Mhz pixel clock for internal LCD of MacBook, but resolutions with > 165Mhz for external TV is still not activated.

from mac-pixel-clock-patch-v2.

So you get 4k@18Hz does work? If that is the case thene there is something wrong that is fixable! Doesn't matter if the tv can receive 18Hz good.. As long as your computer is sending it, it should be able to work.

from mac-pixel-clock-patch-v2.

Do you have 2 TB ports? Sometimes it matters which has ne you use..

from mac-pixel-clock-patch-v2.

Yes, I can switch to 4k@18Hz output, but TV displays that this signal is not supported. Accordingly to TV specs it supports 4k@24Hz, 25Hz, 30Hz video input, but it is not reachable now. I tried to use different HDMI ports of TV and TB ports on Mac, all have the same result.
Maybe there is need to patch something else to enable >165Mhz pixel clock for TB video output?

from mac-pixel-clock-patch-v2.

Tv spec https://www.sony.co.uk/support/en/content/cnt-specs/KD-55X9005B/list
3840 x 2160/24p (HDMI 2/3)YES
3840 x 2160/25p (HDMI 2/3)YES
3840 x 2160/30p (HDMI 2/3)YES
4096 x 2160/24p (HDMI 2/3)YES

from mac-pixel-clock-patch-v2.

I'm sure the TV supports it well.. did you try using a normal HDMI cable? does you mac have HDMI out?

from mac-pixel-clock-patch-v2.

My mac have HDMI output but I have no HDMI2HDMI cable near me right now. I can get one on Monday and check.

from mac-pixel-clock-patch-v2.

Your mac does support 4k@30Hz without any modifications over HDMI.. still weird it does not over your current cable.. Make sure you use either port 2 or 3 on your TV the cable should be well capable of 4k@30Hz.. some strange condition it seems, can't think it's not the cable at this point

Thanks, Floris, I will try HDMI port on Monday, maybe it helps. Still I also dont understand the difference..

from mac-pixel-clock-patch-v2.

I found HDMI cable and when I use it 4k@30 Hz is available and run perfectly.
Still strange that TB2HDMI cable doesnt support it. Maybe this is due to my mac configuration.
I will change the cable for HDMI.
Thank you Floris for your help!

from mac-pixel-clock-patch-v2.

I have no idea why.. Very strange.. good it is somewhat solved now :)
