Monitor out of frequency issues

[Texascelt]

Since installing Windows 7, my monitor keeps going out of range. I have a Gateway FPD1975W monitor and an nVidia 7950 video card. I have updated the nVidia drivers, but keep having the issue. The monitor will flash black then come back after a few seconds. About once a week or so, I get the Out of Frequency message on the monitor. If I turn the monitor off and back on, video comes back. Any help would be greatly appreciated.

Have you tried lowering the frequency in the monitors settings?

 

[Texascelt]

I've already changed the refresh rate, and the monitor is set to the optimal resolution.

Try software solution first with rivatuner to see if the problem is solved then go for the flashing...

Try this... add custom resolution and manually select timing for the monitor. It's solved my shrinking picture problem... it could yours as well.

@TBone
I have installed rivatuner too but it seams that it's not functional at all. On a windows XP, setting rivatuner to unlock GPU has turn my card into a 384-bit with performance boosted to the sky-high... All new games worked on ultra high details (Turok, FEAR 2, Far Cry 2, Lost Planet... except Crysis which i have to downgrade to mix of the lower and high details) even if my card is Gainward 8500GT Golden sample. On a W7, even on a middle details is hard playable even on a DX9 mode. With or without rivatuner, it's a same performance so I must assume that it's not functional.

 

[Texascelt]

The settings won't allow me to select any timing my monitor won't support. I'm going to try to uninstall the current drivers and use an older version of the nVidia drivers and see if that resolves the issue. Otherwise, I'm screwed until an updated driver comes out.

 

[torrentg]

I dunno. This is software from the manufacturer for the monitor. See if you could do something with this.

Downloaded and installed, we'll see if it helps. I changed a couple of settings.

Didn't work. Really frustrated. Think I'll go back to Vista, at least I didn't have this problem with it.

In an earlier post you mentioned you installed the latest NVidia drivers.

Did you mean the Windows update version, or the latest from NVidia's website?

Another thing.
Have you tried another cable?

greetings

 

[SquonkSC]

Another thing.

What cable do you use? VGA? DVI?

Gateway Support - Video Modes

Resolution |  H Frequency | V Frequency |  DVI Mode?
 1440x900     55.935 KHz     59.887 Hz      Yes
 1440x900     70.635 KHz     74.984 Hz       No

Those are precise, 100% VESA CVT Standard.

Please post your EDID dump.
I've attached a custom inf that might help, but it's not based on your EDID so therefore use it at your own risk!
You need to create a custom resolution of 1440x900 @ 60Hz/75Hz(75Hz only when using VGA input) and choose CVT Standard at the Timing dropdown. That might be the reason why you cannot create any.

If still not working, there could be too high variations in H/V frequency and your Monitor Range Limits are too tight and get crossed sometimes. You could try using CVT-reduced blanking instead of CVT, if your monitor suports it (test only on 60Hz).

As a final hint, I would suggest testing the monitor on another GPU/computer with those two custom resolutions.

Good luck.

No... you didn't understand... Of course that it's hiding resolution that your monitor can't support. I said that you ADD custom resolution. Manually change timings of your monitor and force resolution and refresh that you used to have.
You have GTF, DMT, CVT, CVT reduced blank. Try one of those settings instead of automatic timing. Updating drivers won't help as far as I can see.

 

[Corpsecrank]

Yes I agree drivers would not be the issue. If the monitor is going out of frequency then the issue is with the refresh rate. To solve this you have to make sure that your forcing the monitor to run at a frequency it can handle.

You don't want anything to change the refresh rate of the monitor and that is why you have to force the refresh rate so that it can not be tampered with by anything else.

Also this is a common problem while gaming when the game is adjusted to a frequency that the monitor cannot handle however fixing that is much easier as you simply restore the game to default settings and then select a lower frequency.

At any rate the problem is not that big even if it might seem like it is you are just going to have to force the refresh rate and figure out the maximum frequency your monitor can handle at the resolution you want to set it at.

The optimal resolution is usually pretty high I know my optimal was the maximum resolution these monitors could even produce. Try setting the resolution to 1024x768 as that resolution is fairly easy for any monitor to handle. If it does not go out of frequency at that resolution you can bump it up a notch until you get a resolution that does not stay stable. Should give you a better idea how resolution effects refresh rates.

What I don't understand is... your post. It seems that I suggested the exact same thing, only more precise: "You need to create a custom resolution of 1440x900 @ 60Hz/75Hz(75Hz only when using VGA input) and choose CVT Standard at the Timing dropdown. That might be the reason why you cannot create any. [...] You could try using CVT-reduced blanking instead of CVT, if your monitor suports it (test only on 60Hz)".

Are we talking about monitor drivers? Because if we do, then I have to disagree with both of you. We need to get the facts right:
- It used to work before Windows 7, so we can rule out bandwidth problems (resolutions, frequencies).
- The cables are prone to failures but for that you cannot blaim Windows.
- The most relevant changes are... the GPU/monitor driver. Those two are interconnected.

Windows learns about the capabilities of your monitor from the device itself (i.e. EDID), if it supports PnP. Sometimes manufacturers update those by means of a custom driver inf, with stuff like maximum resolution supported, refresh rate limits etc.

The reason I asked for an EDID dump is that I suspect Windows 7 does not get the right timing definitions and sync scheme reported by the monitor. It's known that Microsoft changed something in this aspect, leading to all sorts of problems. Until I see that EDID dump, I have created a custom monitor driver based on a compatible EDID. It will inform Windows that it prefers the 1440x900 resolution at those exact timings (CVT) as specified by the manufacturer. It should work by its own, but if for some reasons those preferred detailed timings are ignored, you need to mirror them in the GPU driver by adding a custom resolution of 1440x900 with CVT timings.

Let's wait for Texascelt.

 

[Texascelt]

From nVidia's website, I am using version 190.62. I have not tried another cable, slipped my mind. I'll give that a shot.

I'll also give the EDID dump a shot. Can't hurt. I'll let you know how it works out.

 

[bobdynlan]

Let me be clear: the inf i've attached in the previous post it's a driver for your monitor, not for the geforce. It takes few moments to open the Device manager and update the monitor driver with the custom one, it will not blow up your hardware so please give that a shoot, too. If anything goes wrong (out of range at windows startup), you can press F8 at boot and choose Enable low-resolution video and then remove the custom monitor driver. Or you can wait for me to take a look at your EDID dump (that you need to post here) and see if it's the real culprit.

I haven't tried the monitor driver yet. I'm also using VGA due to the DVI port on the monitor not working. Known issue with the monitor.

I haven't tried the monitor driver yet. I'm also using VGA due to the DVI port on the monitor not working. Known issue with the monitor.

That's why I asked.

But your kidding about DVI not working right?

Known issue? And you accept that?

DVI gives so much better image than VGA, and it doesn't have issues with refresh rate.
You should not accept it not working.
Let your supplier supply you with another model that does what you pay for.

Good luck.

Excuse my ommision, but a more complete dump would be possible with softMCCS from entech. Select your monitor's name. File -> Save EDID as... and choose Save as type Raylar EDID file (*.dat). This may help identify the reason why the DVI port is not working (I suspect a bad EDID).
