Can't change Refresh Rate

To try to get my new Samsung LN-R268W monitor to show what's on the screen of my Power Book G4 (OS 10.4.5), the lady at Samsung Customer Support said I need to make sure my Refresh Rate is 60 hertz. System Preferences>Displays>Color LCD>Display had the Refresh Rate showing a greyed-out "n/a." Advice?

Is this before or after you've got the image on your
Samsung? If it's before you've connected it, or used
the F7 key to toggle to mirror/span mode, the only
display you'll see under System Preferences is the
built in display. And the refresh rate for that will
be "n/a".
Most monitors will be auto-detected by OS X, and the
refresh rate will be set without any input. My 20"
widescreen Dell LCD automagically defaults to 60Hz.
At any rate, refresh rates for LCDs are kind of
meaningless - they don't actually refresh like old
CRT monitors do.

You're right. Today I learned from talking to somebody that I should turn on my monitor before I turn on my laptop. Page 53 of the Apple manual "Getting Started With Your Powerbook G4" suggested the opposite. However, if I had read page 53 and its reference to page 97 more carefully, I would have checked the "mirroring" box.

Changing refresh rate blanks screen indefinitely

Hi all,
I'm new to the mac world and I was exploring OSX upon bringing my new Mac Pro home.
I have an old 17" Benq LCD monitor (upgrading soon) that I had hooked up using the analog to DVI adapter. I've heard that LCD's usually always are set at 60Hz but stupid me had to try other refresh rates. I set the refresh rate to 80Hz and the screen went blank and a box came up stating the refresh rate was "out of range".
I thought that it would automatically revert a la XP but after 5 minutes nothing. So in the meantime I just swapped to a different video output on the video card.
Could someone please tell me how I can revert the refresh rate to 60Hz so that DVI output can be utilized.
Thanks for reading!

Use the "Gather Windows" button in the "Display" pane of "Displays" System Preference. You can change setting for both displays from one display. You can also check "Show displays in menu bar" to get control of both displays.
Resetting PRAM, or a Safe Boot might help.

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).

1st : It runs perfectly fine at 1280x1024@75Hz in Windows XP/Vista, so there is no reason it shouldn't work in Linux. In Nvidia-panel there is even the 75Hz option in the drop-down list when resolution is 1280x1024.
2nd : It isn't easy on the eyes at 60Hz compared to 75Hz, even more when i play games (Quake 3 for example).

I have multiple songs I would like to include in my slideshow. Can I change the rate of presentation for each song? For instance, upbeat song with a 2 secong presenation time and slower song with a 3 second presentation time?

Alternatives to iPhoto's slideshow include:
PhotoToMovie $49.95
PulpMotion $129
FotoMagico $99
Final Cut Pro X $299
It's difficult to compare these apps. They have differences in capability - some are driven off templates. some aren't. Some have a wider variety of transitions. Others will have excellent audio controls. It's worth checking them out to see what meets your needs. However, there is no doubt that Final Cut Pro X is the most capable app of them all. You get what you pay for.

Cant change refresh rate

hi
2 days ago i put in a connect3d 9600xt and it works great.
BUT my screen flicker when using 60hz refresh rate and i had it on my onboard gf4 to when using 60hz.
but its till there now when raising it and i tried all rates between 60-200 no difference at all.
dxdiag.exe reports the rate i have chosen.
i uninstalled old drivers and at the same time i uninstalled realtek drivers because i put in a sb audigy which works perfectly.
got the latest driver from connect3d webpage.
directx 9
anyone
good night

its not a stupid question when it comes to me
rebooted several times.
right now im running 1024*768 32bit and windows reports im running a refresh rate of 150.
the gfx card only supports 120hz in this resolution.
i can chose up to 200hz
my monitor supports up to 150hz
ive tried every available rate between 60-200hz no change whatsoever between them.
i hate when it flicker.it gives me headache
dont have any monitor drivers.
its running as a standard monitor.
never had this trouble with the onboard gfx before because i just change it from 60hz to 75hz or higher.
it disappears when using 70hz or higher.
its barely visible.

Can't change sample rate for digital input on Mac Pro

Hello all,
on my Mac Pro with 10.4.10 I can't change the sample rate for the digital input. Whenever I choose 48000 or 96000 Hz it returns to 44100 Hz after a few seconds. Feeding a 24 bit/96000 Hz signal from an external ADC into the optical input doesn't help. No input signal is available for digital recording software such as Sound Studio or Cubase. After changing the sample rate in audio midi configuration to 96000 Hz the sound can be heard for a few seconds but when the setup returns to 44100 automatically the signal is, of course, lost.
I've deleted all relevant preferences and restarted with resetting paramter RAM. Still the same. With external hardware such as M-Audio Firewire equipment setting the sample rates works properly.
Thanks to all for helpful clues.

Hi,
when E&M signaling is configured on digital interface like the VWIC is, 2 or 4 wires operation is not applicable because there are no wires at all, and reported only for compatibility with the analog E&M card.
Consequently, you cannot configure that and it will not make any difference to effect of the connection.

Can't Change Frame Rate in Properties

To change project properties in FCPX you click the wrench icon, which brings up a window to select 720p, 1080p, etc as well as frame rate. The problem is, there are no options in the dropdown for the frame rate in all of my projects, it chooses one automatically (seemingly arbitrarily) and you can't change it.
I thought that when the progam says it would detect the properties of the first clip and adjust the project properties to match, it would actually do that (maybe I should have known better). So I imported my standard 1080p 29.97fps footage from my Canon 7D and then FCPX automatically set the project properties to...720p at 24fps. Curious, no? No problem, I thought, I'll just go to Project Properties and manually correct FCPX. But it was not to be, as FCPX had decided to give me only one option in the frame rate selection: 24p. But no, I thought, I would very much like my properties to be 29.97 so as to match my footage. But FCPX did not agree with this, and would not change its mind.
Has anyone found a solution to this?
Do any pros still use Final Cut Pro?
Thanks,
Kurtis

It may be possible that a .jpg was the first thing in the project, which may explain the seemingly random properties (why wouldn't they just make it default to a more common setting like 1080p 29.97?) but I digress.
And it's a very stupid move to revoke the ability to change project properties while clips are in the project, that makes no sense.
I'm begining to think that Apple has really failed with this new version of Final Cut; and I've been using Final Cut for years. I am debating switching to Premiere, but I will give FCP X a bit more time to redeem itself.

Can no longer change bit rate in AAC custom import settings

I've been re-ripping all my CDs at the new higher bit rate. My import settings were AAC Encoder -- custom, originally set to 256 kbps, VBR, and auto for the other two settings. However, some CDs I wanted at a lower setting, so I would go change the bit rate to either 192 or 224 (just so I'd have more room on my ipod) and there wouldn't be a problem. But now it's stuck -- the pop-up box no longer opens when I choose import settings, AAC Encoder, Custom, so I can't change the bit rate or anything else, and it's stuck on 224 kbps. I can still change bit rate and other settings in the custom menus for MP3, WAV, etc., just not AAC. A repair install of iTunes did not fix the problem.

Hi, Ed. I am running iTunes 9.0.3.15. When I click custom, the settings description in the details box display what they were before this thing happened = 112 kbps (mono)/224 kbps (stereo), VBR, optimized for MMX/SSE2. The pop-up dialogue box that used to appear (where you could choose the specific bit rate from the drop down menu) does not appear at all.
However, when I choose anything other than AAC Encoder, and then pick custom, the pop-up box appears and I can choose the bit rate and adjust the other settings as usual. It's just not happening for AAC Encoder anymore. Since the total un-install (following Apple's specified order) and reinstall didn't work, I'm baffled how to fix this .... (If it makes a difference, I changed the bit rate in the custom box while a CD was being burned...Apparently that was stupid, but I had done it previously without incident.) Thanks.

Problem with ATV refresh rates and frame rates

I live in Australia and as such I am subject to PAL, so when I set my ATV up I set it to 720P 50Hz, when I purchased a TV season the episodes were running at 25fps and played back flawlessly with no dropped or added frames. My problem occurs when I download movies, all the movies I have bought are running at 24fps and suffer from quite noticeable jitter, almost like the 24th frame is duplicated and added as the 25th frame, I assume it is something like this as the pause happens every second.
So has anyone had a problem similar to this and if so what do you do about it?
Does the ATV playback all sources (24/25) smoothly even if it has to convert?
Could it be caused by my TV?
Any help to any of these questions would be great.
Thanks.
Tim.

With my particular Apple TV setup and TV combination, I find that setting to 1080p (60hZ) gives my the best all-round round results.
This does result in -slightly- jerky motion with 25fps material (especially old British TV shows), but it's bearable. It's particularly noticeable with sideways scrolling text and credits.
The one thing that is peculiar on my setup is if I use 720p (either @60hz or 50hz) and watch an iTunes-purchased HD episode that is encoded at 24fps I get very odd motion effects indeed. Every few seconds the video appears to speed up almost like it is 'catching up' with lost frames - very hard to explain exactly how it looks. Anyway I set to 1080p and this effect is gone completely. It also goes away if I set to 1080i. I think something queer is going on with 720p on the Apple TV (at least with my TV there is). This happens with both HDMI and component outputs.
It may be worth trying 1080i at either 50 or 60Hz if your set can't do 1080p.
I would also suggest that 60hz in theory should give a smoother motion for 24fps playback than 50Hz.
My basic problem with all this is that on even a cheap DVD player if a disk is 50Hz, the player switches to 50Hz output and if it is 60Hz, it will change to 60Hz. The Apple TV stays fixed. It's a shame it can't autoswitch refresh rates.

[solved] Tearing Problem / Refresh Rate

Hey,
i have a huge tearing problem. Watching movies is a real torture.
I think it's the refresh rate. The recommended refresh rate for my display is 60Hz (@1920x1080p). But i can only choose 50Hz in the XFCE settings (link).
Anyone can say how to change this to 60Hz? If any configs or hardware specifications are needed, please let me know.

It's a nvidia 8800 GTS.
If I choose Resolution: Auto in nvidia-settings I can only use Refresh Rate: 50Hz in XFCE settings.
If I choose Resolution: 1920x1080 60Hz in nvidia-settings I can use Refresh Rate: 50Hz or 122Hz in XFCE settings.

Ti4200-VTD8X (MS-8894) refresh rate problem

I upgrade my Geforce3 Ti200 VGA to Ti4200-VTD8X (MS-8894). My monitor is Samsung SyncMaster 955b (19").
My problem is: I can not get refresh rate 1280/1024 85 Hz (This is the recomended rate of this monitor). I have instaled the newest monitor driver.
Ah.. I have a 2nd problem. My OS is Win XP prof. In the "display properties" window there is a place called "MSI information". In that window nearly all my VGA properties are wrong. It saya my memory is 32MB and SDRAM. AND i can not change the check boxes there. Can you please help me to solve my problems.
Thank you,

drtolga,
If you want to be able to have the hidden functions, create a file with notepad and put this in it.

Save it as agpsetting.reg to your desktop or anywhere you like. Then run it and it will give you all the hidden options from nVidia which include extra Resolution settings for your desktop and overclocking for both the memory and core.

Incorrect CRT refresh rate after latest xorg update

Hi
I upgraded (pacman -Syu) a few days ago and now my CRT displays an incorrect refresh rate so it actually makes my eyes cry ! Very annoying, as you would imagine. I haven't been going with any problem of this kind for years , so i don't believe this is coming from xorg.conf (unchanged for a long time), unless newest xorg or nvidia packages require some new settings for xorg.conf that I am not aware of.

I guess this the price to pay dealing with Arch : you're always up to date, but the update often breaks something that just worked fine.
Hope someone has an idea.
Thanks/

yaourt -Syu of system messed up my nvidia or/and xorg.conf settings also. Now I can not choose 1680x1050 resolution for my 22"LCD, nvidia-settings would let me choose higher ones and lower ones but not the right one. Having only one screen and until this setting up xorg.conf have not taken that long.
[EDIT] Downgrading xorg-server and xorg-server-utils solved the issue for me, only had to to change refresh rate at nvidia-settings.

Is there a way to increase the refresh rate of the Worklist portlet?=10GR3

BPM 6.x used to refresh the worklist a lot faster. Is there a setting (in Studio and in Server) for 10GR3 that can increase the refresh rate... Did not find it in workspace.properties file... Anywhere else to look for it?

Chanege the size of the frame

Refresh rate prob w/gf4 4400

For some reason, when I go into properties and select the monitor tab so that I may change refresh rates, the window freezes, and it never displays options, and I have to kill it.
I'm running win2k and just updated to the latest drivers. If someone could help me out, please do, as my monitor is driving me NUTS.

I had a similar problem. :O I fixed it by downloading the proper moniter driver from the manufacturers web site -- Windows usually just assigns a plug and play moniter driver for most monitors.
In my case, by downloading the Manufacturers driver I was also able to adjust my screen size from the ADVANCED settings tab which previously hadn't been an option.
Dont know if that will help.
