Hello

@Brink
Yes, but I don't know, what exactly to change in the EDID, because to me everything looks pretty much normal. baarod is working on it, as it seems, so it posted my EDID here.

I had a look at that, but that only works if your monitors EDID is wrong. Mine isn't, it has the entry for 60hz at 1920x1200 but win 7 refuses to let it be set.

Well I just installed the newly released 191.07 GeForce driver and this bug still hasn't been fixed! Is this a super hard thing to fix? I'd love to be given some official update about this by Microsoft.

Super hard to fix? No not at all. Windows is correctly supplying the correct refresh rate to the monitor which is set in the modeline. However, applications are incorrectly coded to be dependent on the number 60.

Find out the real refresh rate of your monitor? Well you want to pull down the EDID of your monitor. And look at the Timing section. (This is from my Monitor)
Code:
Timing characteristics
  Native/preferred timing.. 1920x1200p at 60Hz (16:10)
    Modeline............... "1920x1200" 162.000 1920 1968 2000 2160 1200 1201 1204 1250 -hsync -vsync
Where it says "Native/preferred timing" ignore that, nothing but a human description. The real business takes place with the Modeline.

Code:
Modeline syntax: "label" pclk hdisp hsyncstart hsyncend htotal vdisp vsyncstart vsyncend vtotal [flags]
Flags (optional): +HSync, -HSync, +VSync, -VSync, Interlace, DoubleScan, CSync, +CSync, -CSync
To calculate the refresh rate you need to take pclk, htotal, and vtotal. pclk, is the pixel clock in Mhz, so first times it by 1000 twice.

Code:
Vfreq=(pclk * 1000 * 1000) / (htotal * vtotal)
60 = (162 * 1000 * 1000) / (2160 * 1250)
If your monitor is really 60hz you will get that as the answer, however if you are seeing 59hz in Windows then you are going to get 59.9xhz

Ok let me be clear why I know that there is a real problem here: When I turn on my computer, and I go to either 'Advanced Settings in 'Screen Resolution' or 'Change Resolution' in the 'nVidia Control Panel', the refresh rate is at 59Hz. Yes, it may be 59.9 or 59.1, I don't know, but that's not the issue. I can change it to 60Hz in either panel, but when I do, my screen goes black for a second and then it changes to 60Hz. This shows to me that it's really switching refresh rates, just like when you change the resolution it also goes black for an instant. However, the selection box then automatically reverts back to 59Hz **without** the screen going black to indicate that it's really reverting back to 59Hz. This is what bothers me! I don't know if my screen is actually set to 59Hz or in reality it's set at 60Hz but showing 59Hz. If I try to then change it back to 60Hz again, the screen doesn't go black - so what gives? What is it actually set to at this point? I don't necessarily complain about having to do extra things to make things work, but with this, I can't see a reason why it's not getting fixed, if for any other reason but to calm us down.

Yeah, nice maths ... but how does this help? I want f***ing 60hz
I've got no problem with 59hz or 59,95017129 (as calculated), IF and only IF I could use my monitors built-in upscaling function, but that's not the case. I tried with lower resolutions, such as 1024x768: 75hz: OK. 60Hz: OK. 59.xxxxxhz: NOT OK.

@omnimodis78, and DHAmoKK, are you both having issues when the value is DISPLAYED as 59hz? If you are not, then just ignore it. Its nothing more then a display of the actual number being used with the monitor. According to VESA (the one who writes the standard), the integer value of the refresh rate is to be rounded DOWN, not UP like it used to be.

Then get a REAL 60hz monitor. Or one that supplies an EDID with a modeline that computes to 60hz.

Been a while since I posted on this comment...

As you mentioned above, I have exactly the same problem...
Select 60, just reverts back to 59! REALLY IRRITATING!!!

I suppose we will just have to get used to it until Win 7 eventually takes over from XP (I recon a year or 2!) then, only then will this problem eventually be resolved with service pack 4 or something!

BUT, I have run into 2 other problems which I think are sort of related here, and I hope other might be experiencing it too....

Firstly, the aspect ratio thing...
I usually set the nVidia aspect ratio to "use NVIDIA scaling with fixed-aspect ratio". If I run something with a 4:3 ratio, the screen should display it as that and not stretch it.
Now, when I select this, and hit apply, it confirms the change, then just reverts back to using the monitors built in scaling?!?!?! WTF?????

Secondly, When I play games, watch a movie or basically do anything in full screen and something that is very bright comes on, the monitor blanks out for a few seconds. For example, with the new game Castle Wolfenstien. When this was released, I rushed out and bought (waiting for ages for it! Awesome game!). Now, when ever there is an explosion or something bright on the screen, and you are looking in that direction, the screen will blank out!
This is VERY irritating....

From what I have sort of worked out is that it might have something to, possibly, with DirectX and the drivers, but I am not sure...

Anybody else having this problem?

P.S. Sorry for trying to change the subject here, but these could be related somehow?!?!

Hi

@logicearth
Then tell me please, why is it possible to set 1680x1050@ exactly (and real) 60hz with beeing able to use the built-in upscaling function and on the other site setting it to 1680x1050@59hz, where the monitor gets 1920x1200 and shows a 1680x1050 picture in the middle even without any chance of upscaling?

Do you understand my problem (and my possibly crappy english)? I don't think, my monitor's messing around, but either the driver or the OS.

I want the "59hz-mode" removed, at least for lower resolutions. For example: The game "The Whispered World" (I don't know, if you can already buy it in US, or wherever you live) has a fixed resolution of 1024x768 (btw, beside that its a pretty good adventure). My computer sends a 1920x1200 picture to my monitor with the game in the middle at 1024x768 and theres no way of using any upscaling function. My monitor says, it is 59hz.

When I set my Windows desktop to 1024x768@59hz, I get the same result. But when I set it to 60hz, I CAN use the upscaling function. It is all along with that damn "59hz". My monitor shows "59,8"hz, instead of 59,9hz (real 60hz VESA are 59,9xxxx as I already know).

In short: My particular problem is, that this "59hz-mode" blocks my monitors built-in upscaling functions by just sending the native resolution to it when it shouldn't.

Logicearth, i hate to sound like a broken record, especially about an issue which, in the greater scheme of things in life, really doesn't matter at all, but listen, yes, this is an issue we shouldn't dismiss or minimize - in some games, where you can lock the frame rate, or in HTPC apps where vsync is enabled (for good reason), it causes issues. I really doubt that this issue should be overlooked by editing this and modifying that or just ignoring it due to the rounding up or down of numbers. The fact is that XP had no such issues, even Vista had no such issues, with the same hardware and drivers - and voila, Windows7 is magically rounding up numbers, which to some means nothing, but yeah, tearing in games even with vsync enabled is an issue for some, and it's impossible to calibrate apps to monitor refresh rates when my OS doesn't even give me the real and actual refresh rate. Why is there an option if we don't have a choice. And better yet, what is my monitor actually running at as i write this? I would love to know - i guess the dropdown box is at 59Hz but I changed it to 60Hz - so which one is it?

59Hz instead of 60Hz !!!
Hey guys, just some slight weirdness after I re-installed 7 on my laptop. The screen refresh rate is stuck @ 59Hz. now i have the option to select 60Hz and when i do it acepts, but then instantly reverts to 59Hz. any thoughts?

LCD Native Resolution, EDID and 59Hz issues
I'm on the trail of what might turn out to be quite a boon for those folks with resolution and refresh rate issues. Seems that Windows caches a copy of the monitor EDID since querying it can be very time consuming at startup each time. There appears to be no "protection" on that stored binary value...
