Is there anybody who could help me with eyes killin' 60Hz refresh rate, before i'll go blind for f***s sake. I am willin' to pay for an effort. Can't find EDID for my Plasma Panasonic TH-42PX80. I have been playin' on XP 1920x1080 100Hz, so i know it can go better then 60Hz..

Regards people.

I'm 100% sure that the set supports 1366x768. On the xbox 360 it displays full 1080p no problem and the same on ps3. Ps Tried in Vista, Xp and Ubunthu, no luck.
Suggestions anyone?
Thankyou in advance.
Did you edit your inf & update your windows driver to this inf?

I just received a new ATI Radeon 5870 video card, and since installing it I've been unable to run my monitor at any 4:3 resolutions above 1600x1200, or refresh rate above 60 Hz.

Previously, I had been using an NVIDIA 9800 GTX video card, which allowed me to select my typical monitor setup (1600x1200 @ 85 Hz), but only through the NVIDIA control panel.

I never really worried too much about resolutions above 1600x1200 or higher refresh rates, but it might be nice to have access to them. Being limited to run everything at 60 Hz, though, is a deal-breaker.

Some searching on the web indicates that this issue was only addressed recently in the NVIDIA drivers, and may just not have been implemented yet in the ATI drivers. But I imagine that if I could get a properly updated INF file working so that Windows 7 allows the proper resolution/refresh combos by default, I could probably get it working with the ATI drivers too.


My monitor is an NEC Multisync FP2141 SB, from 2002. I've had it since 2003 or thereabouts; it is quite old, but still chugging along happily. Until now.

It supports the following resolutions, according to its manual (which can still be found at http://www.necdisplay.com/cms/docume...anual_0803.pdf):

640 x 480 @ 50 to 160 Hz



800 x 600 @ 50 to 160 Hz
1024 x 768 @ 50 to 160 Hz
1280 x 1024 @ 50 to 127 Hz
1600 x 1200 @ 50 to 109 Hz -- 85 Hz recommended
1800 x 1350 @ 50 to 98 Hz
1800 x 1440 @ 50 to 92 Hz
1856 x 1392 @ 50 to 95 Hz
1920 x 1440 @ 50 to 92 Hz
2048 x 1536 @ 50 to 86 Hz
Because of the age of the monitor, there are no updated Windows 7 (or Vista) drivers. I do have a Windows NT/XP INF file, which I've included in the attached zip file.

This monitor is NOT plug-and-play. When I attach the monitor, it shows up as a "Generic non-PnP Device", and I can update the driver via the included INF via the "have disk" method. I do not need to touch any pins for it to show up as a non-PnP device. The monitor itself only supports a VGA cable connector, which I have running (via a DVI adapter) to one of the DVI output ports on my new video card.


I've attempted to fillow the tutorial instructions, but I'm stopped almost immediately because my monitor does not seem to support EDID at all, and no option to read one appears in Phoenix. Nothing shows up in softMCSS, either, as far as I can tell.

I've tried reading through the linked Microsoft "How to Use an INF to Override the Monitor EDID" document, and unless I'm mistaken it, at least in theory, should be possible to just add some EDID override blocks to the INF I already have in order to make the other supported resolutions and refresh rates available.

But since the tutorials all seem to assume an existing, "bad" EDID is available and I do not have access to one, I'm out of luck regarding how exactly to set these parameters in order to get things to work properly.


Any help would be tremendously appreciated.
You have to change the inf file according to the "How to Use an INF to Override the Monitor EDID" .
Then you can update the windows 7 standard driver to the one that you've changed via previous method (inf file).
If you've done that you restart and then you can readout your EDID with Phoenix.
Then follow the guide from here on.

Edit your inf via method http://www.microsoft.com/whdc/device...edid_over.mspx
Then update windows driver to this modified inf file.
Restart, load your edid into phoenix & follow guide then.

Luwie, thanks for the response.

I mentioned above that I had already read the "How to Use an INF to Override the Monitor EDID" word document previously, but I've got a major issue when it comes to actually implementing the changes described there:

The example provided in that document is completely generic, and I don't know what -- specific -- lines to add/remove from the existing INF file I have on-hand in order to get it to work properly. In particular, there are a couple blocks of hex numbers which, it seems, should be inserted. But I don't have any idea what to set for them.

I guess I was hoping that someone more facile with the process of fixing these INF files might be able to take a look at the one I already have (which doesn't seem to work properly in Windows 7), along with the how-to document, and would have more luck trying to figure out the specific lines needed to bring the INF file up to snuff.

Thanks Luwie, i'll read it tomorrow and try to do it as they say. Have no idea if 100Hz is a supported rate, but i found that: ''Panasonic TH42PX80 Review: 42 Viera 24p 100Hz Plasma'' on google?!

Just wanted to post an update regarding my own situation: with perseverence, I was able to find a successful workaround to my problem, making use of the tutorial.

I was able to construct an INF file to use as a monitor driver that includes proper EDID override information, allowing me to select most (though not all, because of the 123 Hz cap in the allowed refresh rate values in the EDID override fields) of the defined resolutions and refresh rates specified in the original documentation for my monitor.




For those who might be interested, here is what I found out:
  1. By doing more research, I confirmed that my monitor is still officially "Plug and Play" and should have been sending EDID information to my computer.
  2. As a result, I thought it might be a hardware issue (monitor or video card), or failing that a cabling issue.
  3. I checked my VGA cables and VGA-DVI adapter for any missing pins, and couldn't find any. I tried a different VGA-DVI adapter, and tried swapping which video card DVI port the cable was connected to, with no success.
  4. I found at least one place elsewhere on the web where someone mentioned they had "lost" their EDID information when using a very long cable. Since I need a VGA extension cable to reach from monitor to computer , I thought this might be my problem.
  5. So I moved my monitor temporarily and plugged it into the video card without using the extender. No luck.
  6. Finally, I noticed that my monitor has 2 different VGA input ports available, and swapped the (single, shorter) cable to the other port on the monitor.
  7. Ta-da! My monitor now showed up as a PnP device, with EDID information!
  8. Now, I could finally continue through the tutorial. I ran Phoenix, saved the EDID information as a .dat file, and loaded it back up in MonInfo.
  9. It turns out that the EDID information was slightly wrong (some refresh rates were lower than the hardware allows), so I figured I might as well correct those. I might not plan on using them, but just in case.
  10. I generated an EDID override INF.
  11. I moved the monitor back to where it should be, and reconnected it using the extender cable. Now it showed up as a Non-PnP device again; it looks like the attenuation in the cable is a major factor.
  12. Finally, I updated the "Generic" device driver for the monitor using the EDID override INF file.
  13. Everything seems to be functioning properly. I can select resolutions up to 2048x1536 @ 85 Hz, 1600x1200 @ 100 Hz, 1280x1024 @ 120 Hz, etc. Interestingly enough, these resolution/refresh rate combos are available for selection from the regular Windows 7 settings menus, and through the ATI Catalyst Control Center.
So...success! I'm very glad to discover that it was not a problem with my new video card. Instead, it was a combination of the length of VGA cable I was using and the VGA port on the back of my monitor the cable was connected to.

It seems to be a failing of the ATI drivers that I needed to go through all this trouble at all, since with the NVIDIA drivers I was using with my 9800 GTX, I was able to select higher refresh rates and resolutions just fine, regardless of my lack of proper EDID (or overridden EDID) information.

In my case, I was mostly interested in getting the default EDID settings functional again, rather than correcting any problems with the EDID itself, but I was very lucky that I was able to reconnect things in such a way that I could load my "real" EDID information into Phoenix and save it off, for use in generating a new INF file. There was absolutely no way I could have built up a proper INF file from scratch, without having some raw EDID information to base it on.


Thanks to everybody in this thread who have tried to explain and help those in similar situations, and in particular baarod for his tutorial.

hi to all whose reading this. hope i can get a lil help on solving this resolution and refresh rate im facing on my current setup

currently im running on a ati 5770 on my viewsonic vx2835wm. connecting it with a DVI>VGA cable frm card to monitor. after changing to windows 7. i can no longer display 1920x1200 @60hz. currently im stuck at 1600x1200 @60ghz

have tried >
- changing settings inside catalyst. (disabling edid and set max range to 1920x1200 @60hz)
- uncheck hide modes that monitor cant display

Note - monitor is currently shown as Generic Non-PNP Monitor in device manager

none of those works. saw the guide posted on the 1st page. but upon opening up the files after extraction and installation.

i got no idea on how to go about changing which figure to what is required for me to lemme display my monitor resolution @1920x1200 60hz.

Can i get some help please? attached is my dspinfo incase its needed.

Thanks guys, im hoping this can help me. I have done two infs now. The first one worked (after giving me an out of range, but I have two monitors so it got sorted out, until reboot then = no luck).

Bobdynlan: You say:

"Setup your native resolution and refresh rate:
On the Detailed Timings Tab, select the Descriptor Block featuring Timings, Stereo Display and Sync Scheme.
Use the PED Helper again, with the resolution you want to be selected by Windows as default (native). Input the generated values in the Timings Descriptor Block:"
On what block?

Also, you say "
The Pixel Clk is the one responsible for the refresh rate on your selected resolution, you will have to experiment on that as not all dividers are available (Mod-lines). Please dont exceed the monitor's range limits (Block 2)."

It seems block 2 on default is odd. 1.) It doesnt show a refreshrate my monitor is supposed to support (120 hz, I have the vx2268wm viewsonic).
Also the max v and h values are lower than the min ones.

Can you please clarify what blocks to use when reading default timings and putting new ones?
