How do i change my refresh rate

hi all i have a new Imac i need to change my refresh rate , i have looked in system prefernces etc

There is 3rd party software like Switch ResX that lets you set custom resolutions and refresh rates. I run my 15" rMBP at 48Hz since I edit and watch nearly everything 24fps and it helps reduce GPU strain. I can also set external displays to custom resolutions that they may not support officially, for example my LCD TV supports 48Hz in addition to 24, 50, 60Hz, etc.

  • How Can I change my refresh rate to 75hz for on LCD using 91.47 drivers?

    HI,
    I use a 19" LCD and have always changed my refresh rate to 75hz to avoid ghosting in games like fifa 06 (60hz causes a nasty ghost on my 8ms panel).  I have been using the 81.98 drivers and could create an override to use 75.   The new driver will allow me to change the refresh rate to 75, but will not let me use it - I get the message "The custom resolution cannot be added".   I have coolbits2 installed.  Is there a registry setting that I can add to allow me to change the refresh rate?  If not, I'll just go back to the 81.98.  I am also using the DVI connection.
    Thank you,
    * This is on my Sli PC in my sig. *

    I know that on my particular LCD monitor, if I go above the recommended rates, then the screen will just go black and won't let me see anything.  Usually it displays a message telling me that it cannot display.  I think it especially does this with the DVI connection.
    You may have tried it allready, but just make sure that in your display properties you have unchecked the option to only display resolutions allowed by the monitor.
    You may also want to try and see if it will let you do it with a VGA connection instead of the DVI.
    Otherwise, you just may have to go back to the earlier driver.

  • How to change screen refresh rate in windows 7sp1 and windows 8.1 iso image using dism

    sir when i install windows 7sp1 and windows 8.1 then after the completion of setup when first time windows boots up then task bar is not shown and display is not clear and when i check under monitor settings the screen refresh rate is 60 Hertz and when i
    set the screen refresh rate from 60 Hertz to 75 Hertz, then everything is OK, plz tell me why this happens?
    why windows 7 sp1 and windows 8.1 automatically sets the screen refresh rate to 60Hertz instead of 75Hertz.
    how can i set screen refresh rate 75 Hertz permanently in iso image using DISM ?

    That is not a function of DISM. Resolution and refresh rate capabilities can be determined by multiple causes. Drivers are one, another is that most modern displays will report their capabilities to Windows.
    You can specify display settings with an answer file however:
    <Display>
    <HorizontalResolution>640</HorizontalResolution>
    <VerticalResolution>480</VerticalResolution>
    <ColorDepth>16</ColorDepth>
    <RefreshRate>60</RefreshRate>
    </Display>

  • How to speed Portal's refresh rate?

    Dear All,
    When I develop the portal application with some page modified,
    it seems that portal server has cached the old pages somewhere
    so that I can not see the new one immediately.
    Even I delete the __xx.java and __xx.class in WEB-INF directory of the
    application
    and clean up the temporary files browser uses locally.
    How can I speed the refresh rate?
    Clean some files somewhere else?
    Or is there any configuration turning?
    Alan.

    Alan,
    Making a few guesses:
    (a) Did your page change involve changing the page aggregation via EBCC?
    If so, did you sync the data to the WLP?
    (b) If not, check the following session-parameter in weblogic.xml:
              <jsp-param>
                   <param-name>pageCheckSeconds</param-name>
                   <param-value>5</param-value>
              </jsp-param>
    If you don't find this parameter, add this within the "jsp-descriptor"
    element and restart the server. Use an appropriate value (say 5 sec).
    I don't think browser cache has anything to do because, by default, WLP
    sets Cache-Control HTTP tag to not to cache content on the client side.
    Sincerely,
    Subbu

  • How can I change the frame rate mode?

    Adobe Premiere Pro exports my videos with a variable frame rate. Because of this long videos are asynchronous. How can i change the frame rate mode? So Adobe Premie Pro exports my videos with a CONSTANT frame rate? The original video  has a constant frame rate...

    Sorry my mistakes. I am from Germany.. so...I mean with asynchronous that the video file and the sound file are displaced. In the beginning of the Video it's normal, but if the videos is very long it goes VERY "asynchronous"

  • How can I change the scroll rate of a control

    I need the control to scroll at a faster rate than what Labview provides.
    How can I change this to make the control (with up/down arrows) scroll faster without holding the shift key down and while maintianing the same increment step size.

    If you really want to go above and beyond what LabVIEW gives you, you'll probably have to program it yourself. The best way to implement custom functionality for your controls is by using Event Structures. You could, for instance, hide the regular Increment/Decrement arrows for your control and replace them with custom controls that look the same. Then register for Mouse Down events and increment the control value as fast as you want in that event case. The only difficulty comes in when you need to have multiple such controls, or if you want to package them from one app to another.
    If you want a completely self-contained function that does it all and doesn't require specific block diagram implementation, you probably want XControls. XControls allow you not only to change a control's appearance but also its functionality. The end result would be a reusable control that would look and behave however you want, but wouldn't require any block diagram code from the target application. XControls, I would warn you, can be a bit advanced. Your first is the hardest. After that it sinks in
    XControls are available for LabVIEW 8 Professional Development System and higher.

  • How do I change the bit rate for dls?? How times can I download one song??

    I'm new to iTunes. I already downloaded 3 songs when I realized that the default bit rate is 128Kbps. I tried changing the bit rate to 192Kbps with a (Variable Bit Rate) checked.....unfortunately when I downloaded the next 2 songs the bit rate turned out to be the same.
    Do I have to restart Windows or iTunes before downloading again?
    And now that I have 5 songs with a lower br than I wanted... in order for me to have(download) the song at the higher bit rate...Is it possible to download one song more than once?
    Thanx.

    You have no choice as to bit rate when purchasing from the iTunes Music Store. The official bit rate of all tracks there is 128 kbps (a very few have been reported to be at higher rates, but that's not a choice you can make, it's how the track was encoded by the record company). The setting in the iTunes Importing preference is for tracks you import from CDs only and has no effect on iTMS purchases.
    Is it possible to download one song more than once?
    No. Except in extraordinary circumstances, the iTMS allows only one download per purchase.

    How do I change my music bit rate to accomodate more music on my ipod

    Alders,
    You don't have to change the songs in your library.  Just use the option to Convert higher bit rate songs to sync to the iPod.
    With the iPod selected, you can choose this option, as shown below.  To save the most space, choose 128.
    Note that the first time you use this option, the sync will be very slow, as iTunes needs to convert so many files.  On succeeding syncs, it will be faster, since only new or changed files will be shrunk.
    Also note that this option puts the smaller files onto the iPod but leaves the library copies unchanged.

  • How can I change the frame rate of a project in imovie 10?

    My problem is: I made a gopro movie with a frame rate of 50 fps. I imported it to imovie. So far so good.
    Scrubbing over the clip i found one single frame which looked amazing. So I draged some seconds of that clip into the timeline (the project if you will).
    The goal was to make a freeze frame out of this "spezial" frame.
    Unfortunately I could not find this frame in the timeline any more - it's gone.
    I think imovie dropped half of the frames to fit the clip into the projekt, which I assume is using 24-25fps.
    The only solution I found is to decrease the speed of the clip to let's say 50%.
    But is there a better way?
    Can I change the frame rate of the projekt somehow? I think it was possible in imovie 11.
    many thanks
    Rainer
    (from austria)

    iMovie 10 won't share at 50 fps and so for 25 fps output probably drops every other frame.  This is different from Imovie 9 which could handle 50 fps.  However, if you do 50% speed it will use all the available frames so that is indeed the way to find the frame you want.  After you have made a freeze frame I think you can switch the clip back to normal speed.  I am not aware of a better way in iMovie 10  By the way there is also no facility to export a still of a frame in iMovie.
    As a GoPro user I think FCP 10.1 would be the best choice.

  • How do you change the frame rate (or fmp) of a project once you have already started?

    I have been working on a project for a long time now, and I just reliezed that the frame rate of the project was 25 where as all my clips were in 30. Is there any possible way for me to change the frame rate even though I've already started the project? or do I have to start again?

    Hi,
    I've had a really good search through our documentation and website but there's no previous record of that error code. However, a quick google search turned up lots of things on MatLab user groups and the MathWorks forums.
    MatWork's official stance is that the PCI 7342 is not supported in MatLab. They have a list of supported hardware here:

  • How can I change the sample rate (delta X)?

    Hi, I create vi which can measure resistance, it will record the data and write to a file.
    however, I want to change the sample rate which is delta x. is that anyway I can do?
    I have try to put a clock inside the loop, it does slow down the speed but not the sampling rate.
    Please help me!!
    Thank you!

    Hello Shan405,
    Adjusting the Reading Rate of a DMM
    As noted in the above DeveloperZone article, there are a lot of factors contributing to a reading rate of a DMM. 'Sampling rate' can only be configured in digitizer mode, which can only be achieved on the flex DMMs
    Using the NI PXI-407x DMM as an Isolated Digitizer

  • Dropping frames in render.. How do i change export frame rate

    I have a film clip shot on the canon 5d which shoots only at 30fps. This was no issue in FCP as the preferences allow changing the frame rate.
    The project plays fine in color, but when it comes time to render the settings are locked at 25fps. This results in sync issues once sent back to FCP.
    Is there anyway to get around this? Is there a preference somewhere that allows me to change the frame rate in color?
    Any help would be greatly appreciated

  • How can I change the velocity rate of my animation?

    Hi all!
    I have a portion of an animation I want to play at different user-defined speeds (within a continous range of values). I saw audio and video files can be configured to that effect via their playbackRate property. Something like that but for a portion of the timeline would be great. Is that possible? I also looked into changing the framerate, but it seems it is not possible in An.
    Thanks in advance!

    Yep your are right its not possible to change the frame rate of Animate content timeline.
    But you can have the same symbol at different timeline durations and play one of them based on your parameters to give illusion of  symbol playing at different frame rates.

  • How do I increase the refresh rate provided by the Tag Engine?

    Good Day,
    Part of an application I've designed reads in various analog inputs from various sources (3 serial, a handful from the NI-6229 and some temps from the USB-9211A).  My Labview software (LV v7.1) is set to read in the values at 8 Hz (every 125ms).  Though when running, the Tag Engine online provides updated information about once a second (for the both the NI inputs and the serial inputs which have been setup to be read throug the Tag Engine aswell).  When going in the tag configurator, the groups that the channels are part of is set up with "Update Rate (secs)" = 0.20s by default.  I don't even get that.  Just a bout once/sec.
    I've tried looking through MAX a bit but can't seem to find anything there myself.
    Any ideas would be much appreciated.
    Sean

    Khalid,
    Right at this time, I don't have the ability to throw an indicator into the code and run it to display as the stand is currently running clearing out a backlog that occurred over the last couple weeks.  That's why I had loaded the tag monitor while they run, and could see there that the values updated (and were timestamped) about every second.  I may try getting in there to accomplish what you suggest when they should be shutting down in about an hour and a half (if below doesn't work).  Does the tag monitor not update whenever there is a value change (and update the timestamp accordingly)?  That's what I understood from what I've read about it.
    I think you may have pegged it though on how the server was configured.  I went into the server explorer and found a setting under LookoutOPCServer->Properties->Groups titled "Update Rate (msec)" which is currently set to 1000.  I'm going to try this out and will repost afterwards (hopefully when it works ).
    Thank you much (again) for your valueable time,
    Sean

  • How do i change Audio sample rate to suit?

    Hi,
    I Just captured a small clip from my DV camera on final express 4. At the end of the capture i got a message saying that the sample rate on my source may be different to the rate on my capture and it may cause the video and audio to go out of sync. This did happen so i checked the camcorder and it is set to 12bit. How do i set the captute settings to suit??
    Thanks,
    Dave.

    Can I ask a stupid question?
    What do you mean "if you overrun" I just encountered all the above issues. First tape imported perfectly once I changed it to 32. The next one appeared to but then like jerryws1431 said, FCE quit. I wasn't here at the point it quit, but if was either after or during the "Validating Audio". Last time I looked it was validating.
    So, if I have a 60 minute tape and I tape 51 minutes, is that too much to have on one tape, or am I completely missing something......
    Tom, thank you so much for all this information! I would have been stuck with out of sync audio had it not been for you!
