| 756843 | 2009-03-16 01:03:00 | Hi, I've got an aging ViewSonic P90f CRT Monitor hooked up to my equally aging Windows XP desktop. About 6 months ago I upgraded the original Radeon 9700 TX graphics card to a slightly newer Radeon 9800 XT. Everything was fine until last week when I got a "View Meter" error message: FH: + 14.5Hz, FV: + 13.6HZ, Status: OVER. The monitor then shut down. Restarting the monitor just refreshed the error message. It seems somehow the frequency was exceeded (with the readings were likely to be missing the '100'). Closing down the computer temporarily fixed the problem but it reoccurred and finally the monitor switched off as fast as it switched on. I connected the monitor to the laptop and it worked fine with the "View Meter" reading FH: + 93.5khz, FV: +84.8hz, Status: OK. I then tried turning down the monitor settings - making the horizontal and vertical settings as small as they'd go and also the "Viewmatch Colour"(whatever that is) from 9300k to 5000k. I then tried attaching it back to the desktop and it worked. I adjusted the Viewmatch Colour back to 9300k and so far so good. Anything I've done is purely "hit and miss" and I'm just waiting for the error message to come back. Does anyone know what's going on with this and better still some suggestions for a permanent fix (apart from purchasing a new LCD)? Thanks in advance Phillip |

| 756845 | 2009-03-16 02:14:00 | The short of it OP.....start the computer in safe mode, that will give you default basic vga settings, once at the desktop change you settings to align with the monitor... | SolMiester (139) | ||

Its funny you say that, cause I've tried it and it doesn't always work. I.e if the resolution is set to a resolution the monitor doesn't support , it works. But not for refresh rate. No idea why. But it should-since it reverts to the default vga driver. Blam |

| 756847 | 2009-03-16 04:05:00 | Hi Thanks for the suggestions. I've checked the settings in both the display settings and in the graphics card settings. They're set the same 1280x1024 85hz (which is the recommended setting for the monitor). I also checked to see if there were any conflicts in Device Manager but there's no problem there. The view meter is consistently showing FH: +63.9khz, FV: +60.0hz. It's discernibly flickering but at least it's not overloading. I've also just downloaded the latest "Standard Monitor Driver" but that hasn't changed anything. Have I missed/misunderstood anything? Thanks Phillip |

| 756848 | 2009-03-16 04:07:00 | Put it on 60hz | Speedy Gonzales (78) | ||
| 756849 | 2009-03-16 04:12:00 | You shouldnt use "Standard Monitor Driver" Try the manufacturers .inf ViewSonic Monitor Installation Disk (driveragent.com) |

| 756850 | 2009-03-16 05:22:00 | Changing to 60hz doesn't seem to have made any difference so I'll leave it on. It looks like there weren't updated drivers from ViewSonic so I'll just install the original drivers if necessary. Dumb question: are the ViewSonic drivers for the graphics card? Is there a conflict between monitor and graphics card drivers? | phijoa (14702) | ||
| 756851 | 2009-03-16 05:24:00 | No the viewsonic drivers are for the monitor The videocard drivers will be for whatever the video card is (Intel / ATI / Nvidia) Dont think the video and monitor drivers will conflict Might be the monitor itself, if its got settings / options, change them back to the default settings |

| 756852 | 2009-03-16 21:42:00 | This morning when I turned the computer on the settings had changed back to 85hz. When I went to change it back to 60hz I noticed that the monitor was now listed as viewsonic p90f. Previously it had just been listed more generically as monitor or referred to by the video card. I'm guessing that when I changed video cards it altered the settings to a generic monitor and since I loaded the viewsonic "Standard Monitor Driver" yesterday (now rebooted) it's now recognising it correctly? I had intended to dig out the viewsonic disk and reload the original drivers but I'll leave it to see how things go. One of the effects of the new drivers (?) is that 60hz is just too much of a strain so I've gone back to 85hz. So far the view meter is giving a consistent FH: +91.1khz, FV: +85.0hz so hopefully my problem is solved. Thanks for all the help Phillip |
