Need custom refresh rates to fix whining/squealing CRT

My new-to-me 2005 eMac is in excellent condition, except for the fact that its built-in CRT monitor whines/squeals at lower refresh rates. The only resolution with a high enough refresh rate to prevent whining is 800x600 (112 Hz). At least in OS 10.4 on my eMac, I can only choose one refresh rate for the built-in monitor per resolution in System Preferences => Displays (all other refresh rates grayed out).
*I need a procedure that will enable me to choose the highest possible refresh rates for resolutions of 1024x768 or higher.* Surfing the internet isn't much fun at 800x600! I understand that using an improper refresh rate will probably lessen the life of the CRT, but my eMac was rather inexpensive and need only last until I've finished saving for a new Mac Mini or MacBook. I've tried shareware programs such as DisplayConfigX and MoniTOR without success. *I think that SwitchResX is flexible enough to do what I need if I input the correct settings, but I do not know what those correct settings might be.*
Thanks in advance for your help!

Thanks for your reply. I agree with you that the eMac's normal refresh rates look fine. The problem is that any normal refresh rate below 112 Hz causes the CRT in my eMac to make an irritating high pitched sound; I think that the CRT is dying.
I've read online that it might be possible to repair the CRT itself, but I have neither the experience nor the tools to safely do such repair work (at least not without a lot of guidance) and it would probably cost more that the eMac is worth to pay an experienced technician to do the work. Using higher-than-normal refresh rates would definitely be the best solution for me.

Refresh rate HP 850 G1 (Intel 4400)

Hi all, I have a HP 850 G1 laptop and in general I'm very happy with it. In the past I only had a slight issue with screen flickering at lower brightness settings, but setting the refresh rate to 40p hz resolved that issue. After updating to Windows 10, however, it was no longer possible to set the refresh rate to 40p hz. Since I hoped reverting back to Windows 8 would solve it, I performed a factory reset. I am currently using Windows 8 again but it's still not possible to switch to 40p hz, not even through the Intel Custom Mode App. The graphics report from the Intel graphics control panel confirms that the monitor supports the1920x1080x40p hz mode. Any help/suggestions to enable the 40p hz setting again is greatly appreciated! Driver Version: 10.18.14.4251

Hi
I have noticed that on some Toshiba notebooks the screen refresh rate is fixed on 60 Hz. I have two of them. On Tecra M1 is fixed and on Satellite 1900 not. I have tested it and there is no difference if the refresh rate is changed.
The TFT technology is much better than on usual monitors where the display flickering is visible on lower refresh rate. On display you will not see any flickering. In my opinion there is no reason for panic.
Enjoy the life!!!

Satellite M55-s3315: Screen refresh rate is 60 Hertz?!

I have bought Toshiba m55-s3315 analog m50-s.... with intel 910 built-in, shared dynamic 128 mb memory; screen - 14.0" WXGA widescreen display with Toshiba TruBrite . Only refresh rate i get is 60 Hertz. I have updated intel chip software and toshiba also ... I would like to know is it possible to get more than 60 Hertz. The only way is to get 85 Hertz is to add extarnal monitor. I there oportinity to get at least 75 Hertz screen refresh rate ??? It was possible with my old HP Pavilion ze 5000.
May be someone could explain me??
Thank in advance!!!

Questions
1) Accelerated Graphics Port - there is enabled if yes that that it is necessary to make that it became accessible.
2) whether Frequency of hertz with 60 can be raised even up to 75.

Hi
I have noticed that on some Toshiba notebooks the screen refresh rate is fixed on 60 Hz.
The display refresh rate is not important on the notebook screens.
TFT matrix doesn't have such thing as refresh rate. It doesn't blink.
TFT like all other LCD screens doesn't have refresh rate parameter, only reaction time.
Your eyes are safe ;)
Ps: As far as I know the AGP port is not available.

24" iMac refresh rate

I am having all those horrible problem with battlefield 2142 that everyone else is having, but i just found the file that has all the configurations for the game, such as the screen resolutions. My normal resolution is at 1920x1200, but the game resolution is stuck at 1024x800 @ 60hz. i tried to enter the larger resolutions including 1920x1200 but the game just crashes. SO thinking about it i think i have the wrong refresh rate. i went through system preferences and at the refresh rate says "n/a" as seen here....
!http://farm2.static.flickr.com/1165/1427575277e25330d756o.jpg!
i also checked system profiler... nothing....
!http://farm2.static.flickr.com/1237/1428482292a9cb9b3555o.jpg!
that being said does anyone know the refresh rates for the reolutions of the 24" iMac?
the help would be greatly appreciated by many including myself x100....

I suspect that 'refresh rate' is only applicable to CRT monitors: my flat-panel iMac has it greyed out as well.
Not sure if the lack of refresh rate selection is normal for an iMac, but I can defnitely select the refresh for my 17" LCD monitor.
It seems more likely that the game simply won't work at higher than 1024x800 - particularly as 1920x1200 is a widescreen format and the game very likely wants a 4x3 format. Try setting your monitor to 1024x768
Some games will refuse to run at resolutions lower than 1024x768 or 800x600, but I've never heard of a game that would refuse to be set at a higher resolution…

I have a macbook pro 2009 and I want to find out what the refresh rate is, I need it to be 70 hz

I need to find out what the refresh rate is. I went into system preferences and clicked on display, and saw refresh rate, but it said n/a. I need mine to be at least 70 hz, I can't find the answer anywhere.

Cannot fix Refresh rate on monitor

Hi Everyone
I used to have the choice of fixing the refresh rate on my Monitor in the
Nvidia settings window, but it is not available anymore, must come with the
Nvidia drivers package but not in the one I have now.
I was able to fix the rate at 85Hz in any game.
I am using a MSI FX5900XT driver version 7.1.8.9
on windows XP PRO
any help would be gratefully appreciated
cheers
riggie

Thankyou Frankenputer, that worked fine the overides section is back, I cannot believe that it has been dropped by Nvidia. The whole idea of good graphic cards,fast processors, etc is to show the best quality image on the screen in front of you. When I load Call of Duty to play online the Monitor reverts to 60Hz so all the money you spend on your fast components are wasted because you have a low quality picture.
I am sure people out there think that because you set the refresh rate at 85Hz in the Nvidia settings on the desktop it remains on that setting when loading and using all there software. I know my computer will not do it so I am sure everyone will be the same. End of Rant.
Once again thanks for your help Frankenputer and Deathstalker

Need to reduce refresh rate

I am running Mac os x 10.2.8 and im trying to go on a web site and all I see is a blank screen. In their FAQ section they say to have : "graphics settings to factory default" or to "reduce refresh rate". Can some body help me with this. Is this even possible? And if its possible to to do what they say I have to do, how can I go about doing this? And were would I go into to do this. Please Help. Thank You

Hello NESTO:
Post a link to the site in question - perhaps we can tell more from that.

HT3492 I have an Acer S239HL display monitor connected to my MacBook pro that just stopped working. Acer customer support said I needed to refresh the display adapter driver. How or where do I find this?

How do I update or refresh the display adapter driver on my MacBook Pro? I have it connected to an Acer display monitor that just stopped working. Acer custoemr support told me I need to refresh the display driver. ANy suggestions on how I do this? Or what I need to download or update/ Thanks.

So the display WAS WORKING connected to your Mac?
Restart your Mac.
Try the monitor on another computer, Mac or Windows, to see if it works at all.

Thanks.

I upped the log verbosity on Xorg and checked the Xorg.0.log file. I found some interesting things.
First, I found this line:
(II) I810(0): Will use BIOS call 0x5f05 to set refresh rates for CRTs.
Later on, I found these:
(WW) I810(0): Extended BIOS function 0x5f05 not supported.
(II) I810(0): BIOS call 0x5f05 not supported, setting refresh with VBE 3 method.
(WW) I810(0): Set VBE Mode rejected this modeline.
Trying standard mode instead!
Presumably, "standard mode" is an eye-watering 60Hz.
This is on a Dell Optiplex GX260 with BIOS revision A09. The video chipset is an onboard Intel 82845 and the driver is Xorg's i810.
Everything works fine with Sun's X server. I get a nice 87Hz refresh at 1024x768. I'm surprised that Xorg can't set the refresh on this machine. It's listed as Test Suite Level 2 certified in the HCL. Unless somebody can tell me what I'm doing wrong here, I'm going to post this incompatibility as a comment on the HCL.

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.

Refresh rate going to 60Hz when leaving fullscreen games

i am using nvidia blob drivers on a single monitor setup - they're working fine except that often (always?) when i am leaving openGL fullscreen game, the refresh rate defaults to 60 (from 75 Hz). anyone knows how to fix this? thanks, jose

this is actually a very good question. i used to have this connected via vga because of second monitor on dvi in my past multiheaded setup but now that i got rid of it.. i completely forgot about using vga. i switched to dvi now and i think the situation is now better - will need to test a few games though. this is how xrandr output looks now:

Refresh Rate Lines!

Hi guys,
I recently had Wifi trouble with my iPhone 3G 16Gb and I got a replacement phone today. I just noticed that the screen seems duller than my earlier iPhone and there seems to be a refresh rate problem. If I look at the screen and slightly shake the phone up and down I can see faint horizontal lines appear and disappear & these lines are also noticeable when playing videos. This is very annoying and I'm sure it wasn't there on my old phone. Can someone tell me if they are having similar issues and if there is a fix.

Yes I have tried changing the brightness.
Also you don't really need to shake the phone deliberately, it's very noticeable to the eye even when the phone's being used normally.
I noticed another problem this morning. When I view the phone by holding it directly in front of me, the blacks on the screen appear to have a brown tint.

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.

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.
