Can't set higher refresh rate than 50 (59) Hz on my monitor[solved]

Primoz · 2010-11-14 16:44:15

My monitor is both Monitor and TV (it's LG M228WA). So I thought that I can't go any higher than 50Hz. And AFAIK when I was using Windows for a while I also couldn't get it higher than 50Hz.
But with googling I got the information that it's supposed vertical frequency range is from 56-75Hz. But on the other hand on the official LG site there's no information about it's refresh rate (their site is really strange like that.. some monitors have this specification an others don't).

Oh I forgot, I have KDE4.5.3 which has Monitor settings in System Settings and I use nVidia proprietary driver...

To add to confusion this is what I get if I run hwinfo:

53: None 00.0: 10000 Monitor
  [Created at fb.71]
  Unique ID: rdCR.EY_qmtb9YY0
  Hardware Class: monitor
  Model: "Generic Monitor"
  Vendor: "Generic"
  Device: "Monitor"
  Resolution: 1680x1050@77Hz
  Driver Info #0:
    Max. Resolution: 1680x1050
    Vert. Sync Range: 50-90 Hz
    Hor. Sync Range: 31-84 kHz

@77hz??? OK I won't even try to understand this anymore...

Sorry, sorry I didn't do enough research before posting this. Actually my monitor is able to have higher refresh rate, but at lover resolutions.
Well actually not everything is so clear cut as I thought, I decided to double check this and see which options the KDE system settings give me and even on lover resolution I can't get the refresh rate higher than 58hz.
Also I found this on ArchWiki:
/etc/X11/xorg.conf.d/10-monitor.conf
Which for me I guess would look something like this:

Section "Monitor"
    Identifier    "Monitor0"
EndSection

Section "Device"
    Identifier    "Device0"
    Driver        "nvidia" #Choose the driver used for this monitor
EndSection

Section "Screen"
    Identifier    "Screen0"  #Collapse Monitor and Device section to Screen section
    Device        "Device0"
    Monitor       "Monitor0"
    DefaultDepth  24 #Choose the depth (16||24)
    SubSection "Display"
        Depth     24
        Modes     "1680x1050_75.00" #Choose the resolution
    EndSubSection
EndSection

Should I do this? Or am I to expect problems if I try this?
Any kind of help would be useful.
(this is almost solved, either way, I'll just wait until someone confirms that a)monitor config isn't a sane idea or b)it's OK and I should just do it.

the proprietary nvidia driver does not report the real refresh rates to xrandr, it uses some kind of hack and enumerates every resolution starting with 50Hz.
To get your current rate you can use this:

nvidia-settings -nt -q RefreshRate

Thanks!

nvidia-settings -nt -q RefreshRate
59,88 Hz

So I guess I have almost 60hz refresh rate resolution...

Also this:

 Attribute 'RefreshRate' (goedel:0[gpu:0]; display device: DFP-0): 59,88 Hz.
    'RefreshRate' is an integer attribute.
    'RefreshRate' is a read-only attribute.
    'RefreshRate' is display device specific.
    'RefreshRate' can use the following target types: X Screen, GPU.

'RefreshRate' is a read-only attribute. darn. That's that I guess... I can't get my refresh rate higher than ~60Hz.
I guess this is solved.
