It worked! My ViewSonic VP2030B has been acting funny and refused to work. After many hours of experimenting I finally ended up on this site. It didn't work immediately, but after hours of work and search for EDID file I brought my monitor back to life! Advice: make sure you use older graphic card. It didn't work (can't fined EDID EEPROM error) with MacBookPro and some new ASUS computer. It did work with an old PC with GT6600 videocard. Go figure... Thanks Komeil!

Hi Anton. Looks like ViewSonic VX2025wm doesn't like the way newer Nvidia cards set refresh rate. On the day I replaced my 8800 GT with an XFX nVidia GTX 460, the ViewSonic was acting strange when Windows 7 x64 booted up. Right before the password screen, hardware initialization takes place. That's when you can hear your modem's relay ticking, and on the exact same time, monitor resolution and refresh rate are being set. VX2025wm makes a bit of an audible chirp noise here when mated to a GTX 460. Later on, I observed my screen is stuck at low res (1024x768) on a fresh start. Contrary to Vista, Windows 7 SP1 64 bit has let me adjust the screen to its native 1680x1050, but after checking the Device Manager and seeing the horrifying phrase "Generic Non-PnP Monitor" I knew my EDID has been erased. Tried reprogramming the ViewSonic EDID utilizing PowerStrip and the XFX Nvidia GTX 460 itself, but it complained that the DVI cable is too long. I knew it's not the cable being too long, but it's the GTX 460 blocking PowerStrip from accessing the monitor's EDID. Tried the 8800GT, but the same error popped up. Replaced the GT with an 8400 GS, and it showed the same error, but managed to fix the EDID.

Now to stay on the safe side, I boot the Windows 7 up with monitor TURNED OFF, and when I hear the chimes sound, I turn it on. This is the solution for me.

I still have my old ViewSonic, because my eyes are in love with it! I don't know what's the magic behind its old panel's technology, but it's the only thing not causing me computer vision syndrome (CVS)... NIOSH says computer vision syndrome affects some 90% of the people who spend at least three hours a day at a computer; I'm on it all day long.

I bought a new GTX 560 Ti and got this error with my vx2025wm. I've never had problems before with my 8800GT. I did the EDID-flashing and it seemed to work but when I reinstalled Forceware it went black again and the problem is still there. The EDID shows up in Powerstrip though. I'm going crazy with this thing and nothing seems to work and I just want to buy me a new monitor. It just sucks because I can't use my vx2025wm as a secondary then.
I might add that everything works fine when I plug the power cord off the monitor but I don't wanna have to do this everytime I start my computer and I want to be able to use the sleep mode too.

Does anybody have this same problem with a new nVidia card and vx2025wm?

My GTX 560 Ti works just fine with other monitors.

Many thanks mate! You have just saved me many hundreds of dollars on a new monitor! Glad to have this old VX2025wm going again :)

2011-04-03T16:26:35.393-07:00

@Matt, if possible, try with older PCI-E VGA cards like nVidia GeForce 7300 GT or nVidia GeForce 8400 GS, or even a laptop equipped with HDMI/DisplayPort converted to DVI. Chances of updating EDID using newer PCI Express cards like the nVidia GeForce GTX 460 are next to zero, and even if the EDID is being detected, an error will occur during the update nagging about the DVI cable length being too long!

2011-03-24T01:03:03.479-07:00

@Alex
Unlike Windows Vista which sticks to 1024x768 on a bad monitor, Windows 7 lets you manually choose 1680x1050 right after 1024x768 display of the desktop. Problem is yours might not have been fixed. To see if the EDID has been repaired, check for your monitor in the Device Manager applet of Windows 7 / Windows Vista, whether it's listed as "Generic PnP Monitor". If it's listed as "Generic Non-PnP Monitor", it means the EDID's not properly restored.

2011-03-23T07:41:14.389-07:00

Ok good news so far: I managed to do all above, plugged the monitor over a HDMI->DVI cable onto my laptop, works fine, can use it in 1680x1050.
Now the Problem: My old WinXP PC to which the Monitor belongs, still has Problems to recognize it. It shows me 5 different Monitors in the control center, deinstalling all of them en searching for new devices results in all 5 of them to come back. Ideas?

Just fixed my fried Viewsonic monitor using your work. Thanks a bunch! My DVI port thought it was an analog somehow with the Nvidia card. Everything works like a charm. Saved me a few hundred $$ on a new monitor.

2010-07-09T08:45:22.304-07:00

I have a RCA LCD HDTV 42' as my monitor, RCA does not offer drivers so it only comes up as Generic PnP Monitor :(, I just got a new(er) vid card ATI HD 3650 and the proper drivers installed but cannot get resolution higher than 1024x768, i spoke to ATI tech they said it's the driver for the TV, spoke to RCA tech they said they don;t offer drivers so it's the microsoft driver. I run vista 32bit, and it's an AGP card, my older card PCI9 yep not pci-e) 256 radeon 9800 runs the resolution at nearly twice this better card is allowing me. Any ideas how to reset/replace/repair the EDID for my problem?

2010-07-06T08:08:27.664-07:00

I used PowerStrip version 3.83 for this and received "An EDID EEPROM was not found" error when scanning for the EEPROM. But this is because this version didn't have support for updating the EDID on a GeForce GTX 275. Tried the same procedure on a GeForce 6600GT on my old PC and it worked perfectly.

2010-07-06T00:56:06.726-07:00

Jarrett, Both DVI and HDMI carry data in their TDMS (transition minimized differential signaling) channel, with the DVI carrying no audio. Being mostly compatible with each other, you can connect your graphics accelerator to the monitor using HDMI-to-DVI (DVI-DL, or dual link, for high-resolution monitors, with all 24 digital pins present on the DVI connector).

I cannot predict what happens if you use the HDMI on the GeForce GT 240 using HDMI-to-DVI-DL, but I think chance of not working (acting the same as the DVI) is more, because I think something is wrong with the monitor, not the VGA.

It’s really complicated, because the DVI connector includes pins for the display data channel (DDC / DDC2, a newer version of DDC) that allows the graphics adapter to read the monitor’s EDID (extended display identification data). If a display supports both analog and digital signals in one input, each input can host a distinct EDID. If both receivers are active, analog EDID is used.

2010-07-05T10:41:21.889-07:00

I have the VX2025WM too, except I never experienced this DVI issue with my 7600GT (it has two DVI ports and both work). I ran into the issue when I bought a GT240 and the DVI failed, but the VGA was fine. I had to return it, but I am wondering if I use an HDMI to DVI cable (the GT240 has DVI and HDMI) will the display work? Does this issue only effect the DVI port?

2010-06-13T17:27:37.226-07:00

I have an LG w2252tq and I'm not sure if the DVI's EDID is corrupted or what. I tried plugging it to our PS3 using a HDMI to DVI cable and the PS3 could not recognize it (black screen for a few seconds then screen comes back on AV cables, had both plugged at the same time). I tried every single trick to make it work but no dice. I know it should work since the monitor is HDCP compliant and I've seen hundreds of other people post PS3 setups with the same monitor using an HDMI to DVI cable or adapter for at least 720p output.

I'm think the EDID is messed up because the only resolutions I get in windows are 800x600, 1024x768 and 1280x720. I also get no screen during POST and the windows loading screen. I tried powerstrip and it says that it can find an EDID EEPROM after scanning. Might be because I'm using a gtx 275, so I'll try again using my 6600 on an old pc. I'll try flashing in the VGA EDID converted to digital, hopefully things get better if it works.

Thanks a million Komeil Bahmanpour.
It is fixed now, I popped in my old graphic card ATI X800 and was fine. Most likelly Powerstrip doesn't like to work with new graphic cards :) Just DVI cable wasn't working at all with ATI X800 so I was pluging and unpluging my VGA cable. Powerstrip detected that DVI EDID was corupted.
I owe you a beer mate.

thanks for the article Komeil,

I have my problem with VX Viesonic 2025wm DVI since build my new PC (and Graphic card from Nvidia 8800GT to ATI 5770) no signal on the screen till system boots up and after that I can see just 1/4 of the screen and by moving the mouse to the sides or top and bottom of the screen to see rest. I tried all the tricks and nothing.
I tried to download your EDID files but I got a message "This item might not exist or is no longer available".
How can I download your VX 2025 wm files? Could You email them please :)
