Generic timing details for 1776x1000:
HFP=166 HSW=88 HBP=274 kHz=34 VFP=44 VSW=5 VBP=76 Hz=30
interlace +hsync +vsync

Powerstrip doesn't work with my video card, but perhaps these settings will work with the techniques here?
It ought to work.

HELP!!!
I carefully removed pin #7 (DDC Data) from one end of the DVI cable by bending it back and forth with a needle nose plier. After breaking off that pin and plugging the cable back in, the screen remained black and the monitor stayed in stand-by mode.

Then I went ahead and also removed pin #6 (DDC Clock) and it's still not working, the monitor remains in stand-by mode. What can I do to solve this?
Note: I didn't bend and break pin #6 but just completely pulled it out (came out really smooth, like a half an inch long piece)

Did I just ruin my cable? By the way it's a single link DVI-D.
Do I have to remove these pins on both ends of the cable?
EDIT: Just removed the pins #6 and #7 on the other end of the cable as well, but to no avail.
Please help me

Additional Info: the monitor is an LG Flatron W2361V.

I wanted to say that I'd been having headaches over the last few days....... Today I thought to myself, maybe it is my resolution.

Ancient Cornerstone p1700 - no chance in hell of getting drivers......

Sure enough, 60 Hertz

I went through the tutorial and got it working. My eyes feel better already

Sony G400

Hallo,

I hope somebody is still reading this thread.

I want to use my old Sony G400 monitor on my new PC (Radeon HD5670 and Win 7 32 bit, Catalyst 10.8 driver). The old monitor is hooked up using a VGA to DVI adapter.
In order to brake to 60 Hz barrier I wanted to do the trick described in this thread.
Unfortunately I cannot read my EDID, neighter by Phoenix nor by softMCSS.

All I have is an INF-file for that G400. I cannot figure out how to make this instruction ("How to Use an INF to Override the Monitor EDID") work, in order to gain my needed EDID file I can work with.


ANY help is highly appreciated!


My INF-file can be found here (http://***************/files/422935335/G400.rar).

Yea of course people are still reading this thread, it seems to be very popular. It's a good source for information regarding custom resolutions and refresh rates.

I think the current generation of ATI 5xxx series graphics cards communicates in its own very (restricted) special way with the monitor and the Windows Registry.

What OS are you using? What are the native specs of your monitor? Max res. & refresh rates? Is it an LCD or a CRT?
If you're using Windows 7 in combination with an ATI 5670, you're gonna have a hard time getting your monitor past the 60 Hz vertical refresh rate limit without attempting to do the physical pin removal from a regular DVI or VGA cable/adapter. Good luck! (unfortunately it didn't work for me, see above post.)

Okay I'm not the smartest tech-savvy guy around, but I've messed with my monitor (LG Flatron 2361V LCD) and my HD 5870 for a month and I couldn't figure out how to trick the graphics card to accept the monitor's modified EDID. I tried everything from adding custom registry entries with custom resolutions and refresh rates manually to the Windows Registry, to using EDID overrides with modified drivers, all the way to flashing my monitor's EDID chip using an old nVidia 7800 gtx that I temporarily plugged into my Computer. Even though that old nVidia graphics card should be supported by Powerstrip, I had some problems flashing the monitor with PS, so I also used a prog called DELL EDID Writer or something like that (in DOS mode) and it actually worked, but I'm not sure if it also writes that extended EDID information onto the chip...
I might have to reformat or find a way to delete all the registered Monitors from my Windows 7 Registry in order to successfully trick the ATI 5xxxx series graphics card to function with a custom resolution.

Anyways, back to your problem:
Unless your monitor is being recognized as a Generic Plug n Play monitor, there should be some kind of monitor EDID stored in your registry.
If you're running Windows, open up your regedit under start>run>regedit.exe
Then navigate to the following directory:
Quote:
[HKEY_LOCAL_MACHINE\SYSTEM\ControlSet001\Enum\DISPLAY\YOUR_Monitor\YOUR_Monitor_ID_Number\Device Parameters]
And inside that directory, you should see a key called EDID. Double-click it and copy paste the values. Open up notepad and paste them and there's your EDID. You might have to reformat it manually by deleting unnecessary spaces. Then try opening it up in PHOENIX EDID DESIGNER and try creating a modified inf file from there.

Where did you get that INF file you mentioned? Does that INF file contain any EDID information? If yes, you should compare it to the EDID information you might find stored in your Windows Registry. Did you try modifying it with PHOENIX yet and creating an EDID override? At which step exactly did you get stuck?

What can I do if my display actually does show up as a Generic Plug-n-Play monitor? I am running Windows7 and and using a DVI-to-RGB adapter on my ATI Radeon HD 5450 video card (that came stock in my HP HPE-210F desktop) to connect to an old Mitsubishi rear-projection CRT-based HDV. Does the pin removal on the adapter help me at all? I get the impression is doesn't. I'd really like to be able to get the 1776x1000 resolution (that I've read these old Mits will display).

Another issue I'm having is that I cannot get the PC/video card to drive both the DVI (with the DVI-to-RGB adapter) and HDMI outputs at the same time unless the desktop is spanned across the two -- but I want them cloned. I think this might have to do with the fact I don't have the same video settings (that I want) available for both the HDMI and DVI outputs.

Any help on either issue would be greatly appreciated!

Actually my old Mits is showing up as "Generic Non Plug n Play"...still not sure what that means for me though.

OK, thanks for all the happy thoughts thrown my way, and thanks to Digital Artist for stepping in. Something went wrong between my thread subscription, mailservers, MX records and whatnot and needless to say, I was not getting all the responses to this thread. I'm going to try to go back from today and answer each post newest to oldest in the hope that I'll get the majority of the folks solved even though it's not fair to the posters that queried first. The tendency to give up while working on this issue is easy -- just buy a monitor with an EDID that works for those of us rolling in the dough or make due with the wrenching headaches, aspect ratio perversions, and technical furor due to failed 1x1 pixel mapping.

BTW, I'm not a monitor designer nor a digital imaging expert. I'm just a guy who came to sevenforums.com and some other folks helped him out with where to look and now what wrote about what I found is turning out to be a hit on Google. Rather than post all this on my own blog or website I'm continuing on here just because sevenforums.com is the best place for this kind of information on the 'net all the way back to when 7 wouldn't even run on most machines. I also have to give shout-outs to entechtaiwan.com for their moninfo app as well as their forum people Rik Wang and Ashley Saldanha.

Now to the point:

1) Cable modifications are an absolute mess and completely subvert the entire purpose of this exercise. This includes any "adapters" you might have. Dump 'em -- they CANNOT provide better performance than the native electrical signals that are generated by your graphics adapter. At best they hide a required signal by cutting a lead, at worst they marginalize it by throwing a resistor into the mix that may, due to temperature gradients give you one result in the winter and another in fall. Or the worst case that was reported to me -- when the kid went to a LAN party his monitor flickered so bad he couldn't play. The box was on the floor with the adapter in front of the power supply exhaust. When he was home it was not.

2) Don't fondle the pins when attached to live equipment. This is mostly TTL (transistor to transistor logic AKA 5V low amp) stuff here folks. A walk across the carpet in winter can fry the I/O in the monitor or graphics and it may NEVER be detected by either monitor diagnostics or graphics card software. Pay as much attention to plugging in your monitor as your CPU. Just to be safe.

3) Just because 7 says it's a Default Plug and Play Monitor does not mean it's not recognized. There is a three letter code that has to be registered (AKA paid for) from Microsoft that determines the Manufacturer that Windows reports to you. Actually the PNP ID has to match and then it can get it from the driver inf so you can name your monitor as you will to impress your friends

4) There is no single utility available from anyone that can to this stuff. Pay me and I'll build a database. Just don't use the X.org unofficial database as there are some wiseacres who submit to it. I tested one of the modelines that looked completely out of range for a used monitor I had in the shop here and sure enough -- smoke. Then fire when I went in to tell the wife not to worry about the smell as "I'd take care of it". Pay attention.

5) Pixel mapping. You can get it. My next tutorial is almost ready.

Ive followed instructions from that topic, created .inf driver, installed it and all went well - after restarting Ive got my custom resolution and refresh rate BUT in device manager I got error 38 under my monitor: "Windows cannot load the device driver for this hardware because a previous instance of the device driver is still in memory. (Code 38)" and after system restart my refresh rate is rejected and unable to be set. Could there be any viable solutions (besides "do not turn off your computer" ones or"install drivers before every restart") ? My monitor is Syncmaster 797DF CRT, videocard ati hd 4770.

Edit:
I enabled "show hidden devices" and deleted all entries under "display device" and installed edited drivers - so far everything is perfect

How do you delete all the display devices from your registry? Even though I only have 1 monitor, I've got like 5 or more display device entries in my Windows Registry (probably from all the EDID overrides that I have tried in the past) and I am unable to delete them because they are locked and I just can't get the permissions, even when logged in as admin and running regedit as admin under safe mode...
