refresh rate can't be changed to correct one

[AntonSpelec]

Hello
I just plugged my old TV to pc (as second monitor) but there aren't any other settings in "display" "refresh rate" only 24 and 23,98 but when i used same setup with same cables in windows my tv was working well on 1920x1080@60
tried to change it with xrandr but i got only black screen (im not sure with this command what to do, so i tried to google it)
this modes have my monitor(tv):

Code: Select all

1920x1080 (0x5b) 74.250MHz +HSync +VSync *current
        h: width  1920 start 2558 end 2602 total 2750 skew    0 clock  27.00KHz
        v: height 1080 start 1084 end 1089 total 1125           clock  24.00Hz
  1920x1080 (0x5c) 74.176MHz +HSync +VSync
        h: width  1920 start 2558 end 2602 total 2750 skew    0 clock  26.97KHz
        v: height 1080 start 1084 end 1089 total 1125           clock  23.98Hz
  1280x720 (0x5d) 74.250MHz +HSync +VSync
        h: width  1280 start 1390 end 1430 total 1650 skew    0 clock  45.00KHz
        v: height  720 start  725 end  730 total  750           clock  60.00Hz
        ...

what to do?

[Grayfox]

Please do the following in a terminal prompt inxi -Fxxxrz and then paste the output in a code box using the </> button.

Also how are you connecting this monitor to this computer?
HDMI, VGA, DVI, Composite, Component.

[AntonSpelec]

Sorry for not responding. I thought i will get email when somebody answers me.
I'm using HDMI same as in windows one (i tried to use it again on windows and it works without problems)

Try getting the 5.11 Kernel.
To get it, open the "Update Manager"
Click on view>Linux Kernels
Select 5.11
Once installed, reboot
Test screen refresh rate

[AntonSpelec]

I installed 5.11.0-38 kernel and it didn't helped
display settings still dont show 60hz on 1920x1080 mode (only on lower resolutions)
i tried

Code: Select all

xrandr --rate 60

but monitor just stopped work until i changed settings again

[Grayfox]

How old is this TV?
TVs use either 24.97i, 25i, 29.97i, 30i, 50p or 60p vertical line draw rates.
i is Interlaced frames
HDMI 1.0 and 1.1 can do 1080p60.

Have you tried changing settings in System Settings>Display?

[AntonSpelec]

I dont know how old it is, but its old
i tried this menu bude i have only 24p
i made sure that im not using old HDMI (tried other cables) and with cable that i use now i can't set it to higher frame rate
(i have dualboot with windows and i cant use that tv without problems on 60p)

When you are at 60hz under windows, what resolution are you displaying at?

Your xrandr output shows that the TV supports 60hz at 1280x720 (720p) but not at 1920x1080 (1080p)

Could it be that you are using the lower resolution in windows and that is why 60hz is working? Have you tried the lower resolution in Linux?

If not, it looks like the system is detecting the wrong available resolution and refresh rate combinations under Linux, and that is a different problem which I do not know how to resolve.

Older TV's are honestly hit or miss with both Windows and Linux. Sometimes they work, sometimes not, and just because they work on one, does not mean they will work well on the other, unfortunately.

[AntonSpelec]

i use fullhd.

If not, it looks like the system is detecting the wrong available resolution and refresh rate combinations under Linux, and that is a different problem which I do not know how to resolve.

well, thanks all people that answered this thread, it looks like i will not solve this problem

Hi,

I haven't been following the discussion, so take this with a huge grain of salt.

Maybe this link will give you some more useful information
