Screen refresh rate

Please does anyone know the screen refresh rate of a Macbook Pro 2.4 GHx Intel Core 2 Duo (Is this is a 60 Hz monitor?). I am conducting a psychology experiment, and I really need this information, and I cannot find it in system profiler? thank you!

just another reason why this was the best investment i have ever made. i +++++ love mac and the "family" thereof! lol
I tried to mark as "solved" but I get an error!

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>

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!!!

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 U200 - questions about screen refresh rate

Sattellite U200-148 WINXPHOMESP2
Video adapter Mobile Intel (R) 945GM Express Chipset Family
Volume of video of memory 128
Problem Accelerated Graphics Port - it is inaccessible
Frequency of hertz the screen 60
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.

MacBook Pro Screen Refresh Rate

I got one of the new santa rosa 15-inch macbook pros with a glossy display about 3 weeks ago. When i play games or look at display settings, i can't change the screen refresh rate. For example, in battlefield 1942, in the display settings i get a rate of "0"for my built in display! Not "60", or "75", just "0". Also, in the display preferences tab in system preferences, there in no refresh rate to set, but all other displays i connect have a refresh rate setting. How to i change the refresh rate of my built in display?

as far as i'm aware, LCD displays do not have a refresh rate per-se
the reason is because refresh rate is a term applied to Cathode Ray Tube monitors (read that as your standard computer monitor, not an LCD one) and in particular the refresh rate is how many times the gun in the monitor rasters a horizontal line onto the screen in one second.
with LCD displays, because they don't use a gun and are not based on CRT technology, they don't have a refresh rate
i could be wrong though, but i'm sure i read somewhere about this

What is the iPad 2's screen refresh rate?

What should my screen refresh rate be?

Hi guys, ive never really understood the refresh rate for screens. I have a geforce 4 ti4200, and my refresh rate is 60hertz, what should it be, or whats the best? Thanks sasarchiver

100 and more is the best for your eyes. 85 is the lower limit for "blindness"..... ; 60Hz is the lowest possible of your monitor and can harm your sight when long-acting.
you have max. vertical and horizontal freq. of your monitor and a screen resolution (for example horizontal 1024x768 vertical)
so you will know the max vertical freq. by counting: (max horizontal freq of your monitor)/(vertical screen resolution)*(0,95)=max refresh rate
eg: you have max 110kHz of horizontal freq. and screen resolution of 1024x768
so: (110000/768)*0,95=136Hz
this is the max refresh but the graphics cards sopports only 120Hz so you choose 120Hz in your graphics driver 120Hz for this resolution.

Boot Screen Refresh rate

Hi all
I just installed a new Xserve on my network, and i'm having a problem with the refresh rate on the boot screen. No matter what I do, it wants to use 85hz, which I know the LCD cannot handle. There must be a way to force 60hz on the boot screen. I tried the instructions at:
http://wiki.osx86project.org/wiki/index.php/TipsAndTricks#
Messingwith_the_bootoptions
But it seems to ignore the @60 I put in.
When I use a regular screen, it comes up at 800x600 at 85hz.
Thanks!

No one has any ideas on this? Still haven't been able to find a solution...

How to set screen refresh rate for linux console (runlevel 3)?

Hi,
I have a CRT monitor, so the refresh rate is always needed to configure. I use 720x400 resolution in console, but the refresh rate is 70hz. Are there any ways to get it higher in console (with KMS or without)?

thank you for replies
But setting the resolution, e.g. vga=773, would not change the refresh rate, or would it?
It would, but usually not to the maximum provided by the monitor. May be it is real to find the place, where it looks for available resolutions linked with refresh rates...
According to the Gentoo page I can use uvesafb for setting refresh rate as well as other settings. And then I found uvesafb page in ArchWiki. But the way to set proper refresh rate is not so easy as I expected, because I need to install uvesafb and it needs additional daemon. And also I think KMS can't work here. However it's better than nothing, if I don't find any other way, I will try this one.

Suggested Resolution & Refresh Rate for 19-inch Monitor

Just had to replace my old 17-inch Apple Graphite Display. I stayed with a CRT and found a new 19-inch Dell M993s for pretty cheap.
Now I'm trying to decide what the best screen resolution and refresh rate is...
The HTML files that came on the Dell CD-ROM give recommended optimal settings for Windows OS's. But I'm not sure I should go by those for Tiger.
Any suggestions?

Just to make it completely clear
You need to have the screen refresh rate set above 75hz so that screen refresh is less visible, the lower the number the slower the refresh rate and therefore the more visible it is and the more strain on the eye. The higher the refresh rate the better.
Find the resolution which gives you 85hz or higher and which also makes best use of screen without making everything really small and hard to see or to read.
I have a 19" Lacie and have it set to 1280 x 1024 85hz refresh rate.

Screen Refresh frequency on my Portege M300 stuck on 60Hz.

Hi,
I can only set my Refresh frequency to 60Hz on my laptop screen.
Watching the screen for a long time at below 75hz can give me a headache.
I all ways set my screen refresh rate to above 75Hz keeping the resolution around 1024x768, prefer 85Hz-100Hz.
Apart from buying asprins or investing in a monitor can anyone help me set my screen refresh rate above 60Hz.
regards
John

Hi,
I have just conducted a survey of Laptops around and surprise surprise. Other manufacturers notebooks can change refresh frequency to above 60Hz, at 1024x768.
I have done Monitor/TFT screen testing and it is recommended for that the higher the refresh frequency the better quality of presentation.
I think Toshiba should address this issue and allow people the ability to set the refresh rate to higher level, where technically possible, not the take or leave it attitude some people have.
So could someone from Toshiba address this issue as it will cost them customers?

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.

IPad Air display refresh rate for full screen movies?

What exactly happens if I play a movie on the iPad full screen with a rate of e.g. 24p, 25p or 50i?
The stated maximal refresh rate is 60Hz.
Will this rate be reduced when playing movies?
Or will frames be dropped / interpolated if the frame rate and the refresh rate don't match?
Or will the movie be sped up / slowed down?
When using the HDMI adapter, I can see that it always outputs 60p, regardless of the movie frame rate. But maybe this is different on the internal panel.
Thanks for any insight!

Should it happen again double tap the screen with three fingers. Then go to settings> general> accessibility> zoom> off.

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.

W540 - Get 75Mz Refresh rates on 3k screen?

The W540 with a K2100 and a 3k screen has a maximum refresh rate of 60Mz. It is not currently possible to lower the screen resolution and get a higher refresh rate of 75 or higher.
If I got to Screen Resolution > Monitor Properties > Display All Modes, they are all 60Mz even when the screen is tiny. Intel's advance feature to create a custom resolution is also disabled.
I've tried some Custom Resolution softwares, but it just made my system crash.
Are there ways around this or potential software updates that could change this?

I don't think there are any mainstream 75Hz LCDs; just a boatload of 60Hz LCDs and a small percentage of 120Hz ones.
You can't "unlock" 75Hz on an LCD that doesn't support driving it that fast, unlike CRTs, where the bottleneck was available bandwidth.
