Changing default monitor refresh rate

Hello-
I have just installed x86 Solaris8 on my system at home. I have a TNT2 Ultra card and I am using the default Nvidia TNT2 drivers included with the install on a Hitachi Superscan Monitor. I am capable of displaying the Solaris CDE at 1600x1200 but I have display issuesthat force me to reset my vertical and horizontal positioning every time I turn on the monitor or ever time the screen resolution changes.
This problem has existed ever since I got my videocard back whenI still had Win98 on the machine. The only way to correct it was to set the default refresh rate for all resolutions to 60Hz.
Is it possible to do this in Solaris8 and how?
Any assistance will be greatly appreciated!
Thank you,
Daniel J. Noah

stop the dtlogin, login on the text console, and run kdmconfig.
In kdmconfig, choose the video card menu entry, don't make changes
to the video card but use on of the multifrequency monitor entries.
For example, the multifrequency monitor entry upto 110kHz should give
~85 Hz refresh rate at 1600x1200, use one of lower freq. entries to
tune down the refresh rate...

  • Monitor refresh rates and Open Firmware

    Does anyone know if it's possible to change the default monitor refresh rate of an iMac in Open Firmware and how?
    Thanks.

    Thanks but I think the iMac G5 does have a refresh rate or something analogous to one, in this case I believe it is 60 hertz. I want to know how to change it in firmware because I believe it will solve an issue my display suffers from. See here:

    Hi Portal Experts,
    How to change the UWL refresh rate for all portal users?
    Users can individually change the refresh rate through "Personalise View" in UWL.But we want this to set it for all users(we have 10k portal users).
    It was defaultically set to 5 mins for all users.How to change this to 20 mins.
    Thanks

  • Set permanent monitor refresh rate without xorg.conf

    Hi everyone,
    Came back to archlinux, made a clean install with gnome 3. Found out that my GDM and Gnome monitor refresh rate is wrong. For GDM I solved it by adding   xrandr -s 1024x768 -r 85 to the gdm init script. Maybe it's ugly, but at least working. I've got no xorg.conf and I don't want to create it only because of this problem. Using GUI screen settings in System preferences I managed only to set permanently correct resolution (1024x768) but the refresh rate cannot be changed there, so every time I boot now I have correct resolution and refresh rate for GDM, but after login I have 1024x768@60 only, so I have to manually issue   'xrandr -r 85' every time I login. Can I fix it without creating xorg.conf file under /etc/X11? What I already tried was creating the config file under  /etc/X11/xorg.conf.d/  and set proper resolution and refresh rate there, but it didn't help. If someone has advice or idea, i will be very grateful. Thanks a lot in advance.

    I think you need to specify the values from the manufacturer's website.
    Here's my /etc/X11/xorg.conf.d/10-monitor.conf:
    Section "Monitor"
    Identifier "Monitor0"
    VendorName "DELL"
    ModelName "U2311H"
    HorizSync 30.0 - 83.0
    VertRefresh 56.0 - 76.0
    Option "DPMS"
    EndSection
    Section "Device"
    Identifier "Device0"
    Driver "nouveau"
    VendorName "NVIDIA Corporation"
    EndSection
    Section "Screen"
    Identifier "Screen0"
    Device "Device0"
    Monitor "Monitor0"
    DefaultDepth 24
    SubSection "Display"
    Depth 24
    EndSubSection
    EndSection
    I probably don't need to specify "Driver" with open-source drivers, but it's easier to just replace it with "nvidia", since I sometimes switch to the proprietary ones.

  • External Monitor refresh rate conflict

    I've got the PB 12" and for a longtime have been using a 17" Soyo monitor with the computer closed and Bluetooth devices. It's a great setup. Now one time disconnected it to take the powerbook, and now I can't run it with just the 17" monitor. I don't want two screens, and I don't want a 12" screen. However, every time I now try to close and wake up the computer, it says the there is a problem with the resolution and the refresh rate, it says it's "Out of Range". Now I figure it's because the computer is trying to send signals to my external monitor just like it was my Powerbook, but my screen can't show them because it has different specs than the powerbook monitor. Please help, if you need more information, please ask.

    you have a CRT projector? If it is a 16:9 projector it doesn't really matter if the refresh rate is at 75 or 85 hz. 
    I know the x200 can do at least 75 hz at 720p, not sure if it can do any higher.

  • 27" iMac Monitor "refresh rate"

    Hello!
    I'm considering buying a 27" iMac but there's 1 more thing that I need to know before doing so.
    Before you go ahead and tell me that refresh rates on a CRT and LCD monitor are not the same: I'm aware of that. LCD screens still have a similar thing, though, refreshing the entire image. Let's call it fps as I've no clue to what it's actually called.
    Since it'll be used, mostly, for FPS games I want a screen who's able to pull off at least 100fps (like 100Hz in the old days) at various lower resolutions. Do you know if the iMac's screen able to do this, and if you do, do you know the various rates for different resolutions?
    Nicolai

    Is it less than two weeks old?  Check if your store has a replacement policy?
    Is it less than a year old?  Check with the local authorized service centers if you feel you have done nothing that could have possibly damaged the machine, as this would be a hardware issue.
    Is it under AppleCare?  Same thing.
    If it isn't expect to pay more than just adding an external display.  If you are in the U.S. http://www.dttservice.com/ is a good company to check out for under non-AppleCare replacement costs.   Mid-2011 should still be under AppleCare unless you bought it really early on.   May 3rd was when it came out in the stores, so you probably are still under the 1 year coverage, but better hurry, unless you registered it with Apple early.   At minimum buy AppleCare so you are covered for an additional 2 years if you haven't already, since it is showing signs of possible wear not normal to be seen.

  • Get monitor refresh rate

    Hello.

  • Change web service refresh rate

    I'm running LabVIEW Web Service with an application which follow the method shown in the weather monitor example. But my problem facing here is I need to keep click the refresh button then the Web Service only can update the latest data for me. So can anyone help me to show example on how to let the Web Service webpage automatically update the value without press the refresh button. Thank you
    Solved!
    Go to Solution.

    First of all your client needs to support it. If you use the LabVIEW HTTP Client (GET.vi and so on) you cannot use this method. A normal browser should.
    Take a look at FindContacts.vi from the Address Book example.
    The help topic linked in the previous post should get you on the way as well. The infos are a bit scattered all over help file but it should be possible to understand it.
    Basically there are two output options for a web service VI: Terminal mode as used in the Weather example and Stream mode as used in the Address Book example VI.
    Use the Stream mode and construct the HTML page yourself, then send it to the browser with Write Response.vi. Somewhere in the top of the HTML page you need to insert
    <meta http-equiv="refresh" content="5">
    So you should return a string like
    <HEAD>
    <TITLE>my title</TITLE>
    <META http-equiv="refresh" content="5">
    </HEAD>
    <BODY>
    <P>If your browser supports Refresh,
    this page refreshes in 5 seconds.
    And add some real contents here
    </BODY>
     See W3C as well.
    Good luck

  • Change refresh rates and resolution on another computer

    Hi, am i able to use a LAN cable from Computer A and connect to computer B then change B's refresh rates and resolution? for example from 800x600 to 1024x768 then change refresh rate from 60Hz to 75Hz. please advice thanks.

    Hi Trig,
    Thanks for your post and I hope your well today.
    There are two parts to this - in my mind:
    1. Changing Screen Resolution Programmatically From LabVIEW
    2. Use VI Server to remotely call a VI i.e. Computer A calling VI on Computer B which then runs the VI mentioned in 1. 
    1. 
    This link is a dev zone article which has code for programmatically changing the screen resolution
    http://zone.ni.com/devzone/cda/epd/p/id/1429
    Try it out. 
    2.
    VI Server
    The NI Example Finder contains some expamples for this.
    Building VI Server Applications
    http://zone.ni.com/reference/en-XX/help/371361E-01/lvconcepts/building_vi_server_applications/
    If you could provide more details, maybe versions of LabVIEW etc then maybe we can help you some more - have you got some code yet? And did you have any thoughts on how to do this?
    Another method I have consider is:
    Using a tool such that runs an exe or script which alters the resoltion.
    Then using the cmd (comand line) or in LabVIEW System Exec.vi to run the exe (via VI Server).

  • X misdetects LG Flatron F700B as 775FT - 50hz refresh rate

    Hi;
    I acquired a LG Flatron F700B today and hooked it up (nice, sharp picture, much nicer to stare at than my venerable, fuzzy Benq V772.) The issue here is that according to nvidia-settings, my computer thinks that this is a LG 775FT.
    This wouldn't be so bad, but there's a distinct difference in specifications between the two monitors - the F700B does max. 1280x1024 @ 85Hz, but the 775FT (which X seems to think I have) only does 1280x1024 @ 60Hz. Interestingly, xrandr reports the maximum resolution as 1280x1024 @ 50Hz.
    As you can imagine, 50/60Hz makes ones eyes bleed... I've tried editing the Monitor section in xorg.conf with appropriate sync ranges taken from the monitor specs at link [1], but apparently new versions of X just go ahead and autodetect the monitor anyway, which is actually working against me here (autodetection is nice, but only when it detects the Right Thing.)
    nvidia-settings only lets me push the monitor up to 60hz.
    Does anyone have any suggestions as to how I can 'persuade' X that my monitor Really Can Do 1028x1024 @ 85hz? I'm tempted to take a cudgel to it and see if it plays nice
    Cheers;
    -lws
    [1] : http://www.superwarehouse.com/LG_Electr … /ps/141938

    Nvidia actually uses refresh rate to report a completely different property, something to do with twinview mode and compatibility with TVs and such  - that's why you shouldn't really worry about what xrandr says...  You can use nvidia-settings to see what the actual refresh rate is, it most certainly isn't 50hz.  If that figure bothers you you can add something like this to the device section in xorg:
    Option "DynamicTwinView" "False"
    This will not actually change how the image is displayed but it will make xrandr return the actuall refresh value.
    This is what nvidia manual has to say about this:
    Option "DynamicTwinView" "boolean"
        Enable or disable support for dynamically configuring TwinView on this X screen. When DynamicTwinView is enabled (the default), the refresh rate of a mode (reported through XF86VidMode or XRandR) does not correctly report the refresh rate, but instead is a unique number such that each MetaMode has a different value. This is to guarantee that MetaModes can be uniquely identified by XRandR.
        When DynamicTwinView is disabled, the refresh rate reported through XRandR will be accurate, but NV-CONTROL clients such as nvidia-settings will not be able to dynamically manipulate the X screen's MetaModes. TwinView can still be configured from the X config file when DynamicTwinView is disabled.
        Default: DynamicTwinView is enabled.

  • Refresh rate settings

    I got a monitor 20.1" Samsung SyncMaster 204b, which blinks on and off when using 1600x1200 60Hz resolution.
    After extensive search I found information that setting the refresh rate to 56Hz would help, but unfortunately that option is grayed out in OSX 10.4.9. I downloaded SwitchResX program and modified the refresh rate via that and it worked! Now the problem is that the SwitchResX is about $15-20USD and to me it feels kind of silly to pay money for grayed out option that I should be able to use.
    How can I enable this option and use OSX regular way to set my monitor refresh rate to 56Hz?
    Mac Mini   Mac OS X (10.4.9)  

    Here is the specs for the Mac Mini I have: http://www.everymac.com/systems/apple/macmini/stats/mac_mini_g41.5.html
    Well, unfortunately mine does not work unless the refresh rate is set to 56Hz. I searched internet quite a lot and it seems that Samsung SyncMaster 204B (or at least some models) does have this problem. I have two of these monitors for my company, as they were cheap and work well with my laptops. Now when I tried both of them on my Mac Mini the problems appeared.
    Back to the original question, how can I force my OSX to use 56Hz instead of the manufacturer default setting? The option is grayed out for some reason and with the application mentioned in first post I was able to change that. That application costs money and it feels kind of silly to pay for grayed out refresh rate option.

  • Altering refresh rates

    Howdy folks!
    I've got an 800mhz emac. The CRT is shot. I am able to use the external monitor plug. I had (have) an external Mac monitor but it is as big as the emac and I am running out of desk space. I bought a 15" Gateway LCD off a craigslister to park in front of the emac chassis. I got the message the the input was out of range for the monitor. I reconnected the mac monitor and tried to reset the refresh rate. There were other rates listed but they were greyed out and not accesible. After lots of reading on this board I found a link to an application called SwitchResX which allowed me to make the changes I need and the LCD is working now.
    Here's the rub: SwitchResX is a 10 day limited shareware product. It costs $18.50 (or thereabouts) to register it. I will pay it in the end if I can't find relief elsewhere but I feel like I ought to be able to accomplish a change in video refresh rates without having to shell out $$ to a third party.
    Anyone know of a more straightforwad, less costly way to achieve DIY video adjustments?
    TIA!
