Resetting a lost ViewSonic DVI connection

I recently upgraded to a shiny new graphics card (NVIDIA 7900 GT) and was bummed when the DVI connection on my ViewSonic VA2012wb LCD monitor couldn’t detect a signal from it and just stayed in standby mode. At first I thought the card was just dead, until I tried using the DVI to D-Sub (analog VGA) adapter to send the monitor an analog signal, which worked fine. This mystified me, since the card and physical port were apparently working, but refusing to output a DVI signal. I’d just unplugged the monitor from my old DVI card, so I figured the monitor wasn’t the problem. Turns out the monitor was indeed (partially) the culprit.

I contacted support at XFX (the graphics card maker) and they recommended the usual (check connections, update motherboard bios, Windows drivers, etc.) but ended up advising me to return the card. Newegg, as usual, was great with their RMA support. Unfortunately, I experienced the exact same problem with the replacement card!

I eventually found the solution in some threads on the Anandtech and [H]ard|OCP message boards. It turns out that there’s a common problem with NVIDIA cards and many of ViewSonic’s 20″ widescreen monitors (most commonly the VX2025 but with mine as well), in which the monitor’s EDID settings get “stuck” into a state in which a DVI signal can’t wake the unit from standby mode. There are two possible solutions. The first, which worked for me, is to take the following steps:

  1. Connect both DVI and D-Sub when the computer and monitor are turned on
  2. Turn off the computer
  3. Disconnect the D-Sub, leaving the DVI in place
  4. Unplug the monitor’s power for at least 5 seconds
  5. Power the computer back on

When I did this, suddenly my monitor recognized the DVI signal and I got a nice digital picture. Another approach, which seems to have worked for a lot of people, is to use a utility called DVI Recover. I’m not sure where that program came from and can’t vouch for its safety or effectiveness, but from reading the message threads it sounds like it’s helped quite a few people.

Anyway, I was pretty frustrated with this problem at first and wasn’t finding much through general Google searches, so I hope this post helps someone in a similar situation. And ViewSonic definitely needs to get their act together and fix this problem!

  1. Hi,
    Thank you so much for posting this. I lost almost all day trying to fix the same problem with my Viewsonic vx2025 and 7600GT, before I found your post here. Thanks bro.

  2. Oh glory! What a great post! :) You’ve saved me many potential hours of frustration. Thank you very much. I was running on an analog kvm and getting ready to buy a pricey dvi kvm but I thought I’d try using my second input and just pushing an extra button to get the DVI signal from my machine that needs it… DING! I was having trouble getting the DVI to show up until I found your post. Thanks again.

  3. Thank you so much!

    I’ve had my Viewsonic VA2012w for nearly a year now along with my 7600gt, and until I read this post I’ve never been able to get the monitor to pick up a digital signal.

    Thanks again :D

  4. It works. Yes.
    Viewsonic VX2235WM and ATI XT850. Your simple solution save me a lot of time and effort to talk to those Viewsonic / AMD tech support.

    KUDOS for you. Thank a lot.

  5. Viewsonic just swapped out my monitor which was having the same problem. Ooops.

    Thanks for the post – at least I know where to look when it happens again …

  6. Is this normal behaviour? I’m thinking of buying a new monitor and I need it start when I turn on my PC. I use a ‘smart’ mains panel and I can’t turn my monitor on before the PC. Surely these monitors are broken and you should be able to get a refund… or is this another example of a unique feature that you should feel privileged to have?
    PS. Is the fix permanent or do you need to apply it regularly?

  7. Andy,

    For the most part, you only need to do it once. In my case I had to do it when I changed graphics cards.

    – rdo

  8. When you to unplug the monitor (step 4), do you mean power or the DVI? I am trying your recommendation with no luck… (have a XFX 7900GT and Viewsonic 2012wb)

  9. You sir, are an absolute legend! I was tearing my hair out on this one till I stumbled across this article, can’t believe how simple it was.

    If the internet had a front page, then this should be on it!

    Cheers,

    Mark

  10. Thank you for doing this website. This has worked for Viewsonic 2025 and XFX 6800.

    As ppl say “Computers can make your life very difficult”.

  11. How you find time for this Ryan, I have no idea but great post.
    i was Having Similar issues with my good but Severely outdated Nvidia geforce 3 ti 200 when Anna bought me a shinny new 20″ Samsung 205bw. Took some troubleshooting but i eventually got it. I still have constant issues with “flickering” wherein graphically heavy Programs, ie one the 90th line of the feature tree in swx, would cause the monitor to blackout for 2 seconds then come back… annoying but definitely better than using an analog signal. I was wondering if you ever experience this kind of issue, and if so, any remedies?

    Well anyways, thanks again for the reference. My employers Bow down to the surfacing skills i learned from you

  12. Thanks again for this as it worked for me too. I just bought this computer less than 2 months ago. Yesterday I had no problems but today, no digital signal upon boot up. I used your fix and everything is OK now. By the way I have a Geforce 8800 GTS card and a Viewsonic VX2235wm flat panel LCD moniter. So far so good!

    :)

  13. Same damn problem with a Macpro and a viewsonic 2025, I´ll try what you posted and let you know if it worked.

    Thakns in advance

  14. Thanks for the tip :D

    I just managed to use this tip to get the DVI signal between my 7950 and Dell 2047 working.

  15. you are a legend had this problem since upgrading to vista veiwsonic were no help did’nt have a clue nvidia mumbled somthing about edid settings but did’nt give a cure thanks a lot steve.

  16. I have a similar problem with a new Sapphire Ati HD 2600 XT & a Viewsonic VG2030wm Monitor. There is no display at boot up. I used the VGA connection to install the new 8.1 Catalyst ,then the DVI would work once Windows was booted up.

  17. I forgot to mention I am running Windows Xp Pro & my X1900 All In Wonder card with DVI always worked,So how can that be a stuck EDID??? I would like to try a LG monitor just to rule things out. My computer is only about a year old, I have the Asus P5W64 WS Motherboard Bios 0215.Hopefully someone can come up with a solution??? Or I guess I will have to try a new Monitor (LG) with HDCP.

  18. Had this problem earlier but forgot how View sonic support helped me resolve which is exactly what you have posted here.Could not remember for the life of me , thanks for the post . Actually had to send one back for a replacement as it had same symptoms but was actually screwed.

  19. Just an update for everyone,the problem is with my Viewsonic. I bought an LG L206WTQ-BF 20.1″ Widescreen,I can see the boot screen now.Monitor has a 3 year warranty & was only $219.99. It also has better specs than the Viewsonic.I am not even going to waste my time with my old monitor,it either works or it does not.You pay a premium price for the Viewsonics so there is no excuse. I think they just went down hill with their LCD line,the CRT’s were amazing, I still have a GT775 graphic series & it’s still as good as the day I bought it about 8 years ago.

    I think Viewsonic just got lazy, as they do not even have a monitor with HDCP, they are not keeping up with the latest standards.

  20. thanks heaps… i got the vx2025w… pain in the ass, with 7600GT. had this problem for months. thanks again!!

  21. YES! That did the trick. I too thought it was the video card (in my case its a 6800). I have the same monitor, with both cables plugged in, but only the d-sub worked. By unplugging the Monitor ( and the d-sub) that managed to reset the monitor (who would have thought you’d have to reset a monitor) and poof, digital days are here again.

    Thanks!

  22. Chris, how do you like your LG L206WTQ-BF ? I’m looking into getting (frys.com $199) but can’t find a review on it. Can you tell me what your experience with it so far?

  23. DVI-I Integrated DIG/ANA Dual , has anyone tried this method? its the connection on both the viewsonic 2025 and the 8800 gt card. i was thinking of getting this cable to try and fix my comp problems, niether the download nor the reset seems to work, i loose signal after the running bar at startup.

  24. my VA2012W does not wake from standby on a macbook running os x leopard, I found that removing the power from the monitor waiting a few seconds that powering on works with that too. May be of use to other mac owners.

  25. The DVI recover program worked brilliantly! I truly appreciate your help. I have a Viewsonic VA2012wb and switched from Analog to DVI. At first the monitor was not recognized, however, running the utility you mentioned fixed it. Thank you so much.

  26. OMG, thank you so much for this info. I formatted comuter like 5 times because I thought there’s something vrong with my GPU, i tried about 20 different drivers for it, and then I found this, pure gold. Thank you one more time!

  27. Hi, this has been helpful till Explorer booted and it got f*ked up again.

    I followed all your steps and when I booted up the monitor found the digital signal I was stoked. But, once, Explorer loaded up it lost the signal and blanked out.

    I have a VG2030wm with Nvidia FX 5200, PLEASE HELP

  28. Thanks for the post. It works!!! I’ve had my VX2235wm Monitor for a year and a half now and I’ve always used it in analog mode. My new laptop comes with a HDMI port, and I wanted to start using the monitor in digital mode. When it didn’t work, I tried everything, but no success. It worked on another monitor, so I knew it wasn’t the laptop. I was thinking time for a new monitor until I tried your simple steps. Thanks.

  29. Hey thanx for the post, it really worked… to some point. Now i can see the computer bios and everything starts well but when the bar of my windows vista fully load then my DVI lose signal again. I can go on safe mode and there is no problem, but when i try to load the windows normally it will just lose the signal.

    I got a ViewSonic vx2025wm and a evga9600 dual digital

  30. Just one update.
    DVI disappear two times in two days. So I have solution that work’s. Disconnect d-sub and DVI cable’s. Leave monitor turned on and on AC. Disconnect AC cable. Press and hold the [Up] buttons on front panel. Plug AC cable, and wait for message NO SIGNAL – DIGITAL ( or ANALOG ). Plug in DVI cable, and you should have DVI connected. Hope it will help somebody.
    Cheers

  31. Thank you! Your post saved me countless hours that I was expecting to spend trying to figure this out.

  32. this is working so WELL for everyone, and not for me – I think I may be doing something wrong, or in the wrong order – I am completely computer ignorant. Can anyone walk me through again? I am turing computer on – getting the no signal digital note (additionally – no sound) from here I am disconnecting the dvi and dsub from the monitor end, and reconnecting. I turn off the computer by holding the power button down (since no screen can not shut down correctly) then i disconnect the dsub from the monitor end. unplug the power from the monitor end. wait – plug back in, and trun computer back on…at what point to reconnect the dsub? or have ai already messed up a step. this is only a year old computer and videocard and monitor. before it went to no signal message on black screen, i noticed the screen would shut down after being in standby mode for more than 12 hours or so, and i would have to reboot the computer to get it going up again, but now nothing works. i am at my wits end, any help is so appreciated :)

  33. I made sure that the DOS CD booted the computer in analogue mode. Then I pulled the analogue cable completely off, and connected only the digital cable. I turned of the monitor. When I booted off the CD I noticed the monitor turned itself on. I pulled the CD, booted off the hard drive and was able to see the graphical boot.

    I am limited to 640 x 480, but that is an improvement over _no signal_. Thanks!

  34. Three years later and this blog is still being helpful. Thanks, Ryan!

    I found that unplugging the power cord of my VA2012wb, with DVI cable in place, then rebooting my computer, then re-plugging the monitor power cord, and then turning on the monitor did the trick.

  35. Same problem suddenly appear with my VX2255wmb

    => solution describe by rikee is OK & save me => Big thanks!

    Since this problem seems to happen regularly on several models of Viewsonic monitors for 3 years, I hope that the information is rising to the manufacturer …

  36. I was having the same problem with my vx2025wm and macbook. I would connect the DVI cable to the mini-DVI adapter but nothing would happen. Finally I unplugged the power to the monitor and connected the DVI to the macbook again and the display was detected, even with no power to it. Once I connected the power all was well again.

    thanks!

  37. I have a Veiwsonic VS11349 with a card 8000gt. Have had it for 1 year and 2 months. Never had a problem with it until 2 days ago. Monitor stays on, just can’t see picture, and I can’t shut it off. Did what you said about like rebooting it, and it wont work, Maybe my monitor is just fried after a year?

  38. Ryan!

    I had this issue after upgrading to Win7 x64v yesterday and this was the #1 google response! Small world!

    BTW, I’m moving to the bay soon…I’ll be in touch.

    K

  39. Thanks a lot for your information!
    In fact i recognized, that if you remotecontrol your computer, the monitor turns on, as soon as the Windows-Login-Form appears.
    So, there is some bug perhaps?
    Something with resetting the card-drivers??

    Greetz

  40. Oh thank you very much! It worked with Nvidia Geforce 8800GT and an LG Flatron W2261VP! You’ re a god! ;)

  41. thanks a mil man… i use a Benq screen and a geforce card and had the same problem and was going to buy a new card loool thanks for this as it now works :-)

  42. Thanks, this saved my day!

    Your fist steps with unplugging the monitor worked for me.

    vNidia 9xxx-series and a ViewSonic VX2035.

  43. Thank you so much! Have this old but huge and only slightly used 23″ Viewsonic that I’d started using recently, and it was doing this, but as soon as I tried your solution if fixed it right up.

  44. I have a ViewSonic VX1962wm with a DVI connection that is unstable (on a Radeon 9250). The D-Sub and DVI cables are both connected, though I’ve only been using the D-Sub because it actually works. I will try the technique above of removing the cable. Cheers!

  45. THANKS A LOT!!!
    FOR GODS SAKE I LOST THE WHOLE WEEK TRYING TO FIGURE OUT WHATS WRONG WITH IT!!!!!!
    THANKS MAN I LOVE YOU!!!

  46. Hi there. Tried this with my Viewsonic VX2025 + Nvidia 7800GT.

    Worked great.

    I remember a few years ago I had this with the same Nvidia 7800GT when the screen’s DVI went screwy.

    I let my sister use my LCD for a couple years (who used an ATI card), and the DVI still did not work.

    Brought the LCD back home tonight and found this site. I saw all the positive feedback so I thought I’d give it a shot too! and IT WORKED YAY! :D

    The only thing I did different was for step 3- disconnect the D-Sub from both the PC and the monitor to ensure only the DVI was present.

    Thanks a lot!

  47. Thank you many times over for this post. You just helped me fix a Viewsonic VG2030wm that stopped sending signal over the DVI port (though the VGA port still worked). I thought the DVI port was dead due to a chip or some connector burning out. Thanks so much for posting this 5 step method and saving me time and money!

  48. I had the exact same problem on my vx2235wm, previous computer was on VGA port, then I hooked up my new computer on DVI, all was fine for 3 months, then it wouldn’t work, tried this method and now it works perfectly.. who would of thought..

  49. Glad this post is still around. Was having the same issue as everyone else with my 2245. If I hadn’t found this I would have probably given up and used the vga.

    Thanks a million..
    JC

  50. I’ve even tried going into the master menu

    hold 2 whilst you press power. Then press 1 and you will be taken into the master menu or via the F in the main menu.

    Either method gives me no DVI
