HP w1907 19" screen shaking

[Albion72]

Tried messing with Refresh Rates = Nothing

It only happens on 1400x900 Resolution, which is the Resolution made for this monitor.

My video card is a ATI Radeon 4850, although I doubt it is a video card related issue.

If I change the Resolution, it all goes away, but the next best resolution from 1400x900 is really really crappy and I don't want to use it.

Any ideas?

I also noticed the adapter that plugs into my 4850 that then allows me to plug in my monitor has a pin thats shorter than all the others? Is this normal?

Are you talking about dvi-agp adapter?

If so, there are four pins that are around the long rectangular contact that are shorter than the other ones.

What monitor are you using?

What monitor are you using? lolol



As per title.

HP W1907

Yes I am talking about that Adapter.

There is one pin within the 8x3 pin area that is shorter than the others. Its one of the pins at aren't around the rectangular contact? Is this a problem?


I am coming to suspect my display drivers. When I uninstalled them the shaking stopped. And yes I am using an HP w1907 monitor.

Are you connected with a VGA cable or a DVI cable? If your screen is shaking then usually you can adjust the refresh rate and up it to stop the shaking. If you dive into the advanced settings of your video card, then sometimes you can set custom resolutions where you can mess with the pixel clock and calibration from there.

The easiest thing to do is to actually drop the brightness and contrast and see if the flicker goes away. Sometimes the CCFL's that act as backlights can flicker to some people at diff brightnesses, but lowering or upping it can cause your eyes to not see it.

Gamma/Contrast drop is a no-go. I'm using VGA I believe, I have limited experience with monitors, the chord that COMES with a monitor is VGA right? I've tried adjusting the Refresh Rates, but that hasn't done anything.

Have you tried to see if there are some drivers for your monitor that are newer, and have you tried updating your vid card drivers?

If the cord has blue ends and has 15 pins in 3 rows, then that is a vga cable, if it is white with 2 groups of nine pins in a square separated by a space, then a horizontal big bar to the left of one of the groups of 9 pins, that is a DVI cable.

Its VGA. I was not aware there were drivers for monitors.. :D

Yes I have the newest available drivers for my video card.

EDIT: I installed my monitors drivers, didnt change anything.

with your monitor drivers, you should be able to now select the right resolution for your monitor 1440x900. Try this and see what your monitor does.

Ive always been able to select 1440x900. The funny thing is, 1440x900 is the only resolution it shakes on.

That isnt what you said in your original post, you said that it shook at 1400x900.

It is very rare, but maybe your vga cable is bad. Since your monitor supports DVI, i would suggest you try it on DVI and see what it does. You really shouldnt be running your LCD off of vga anyways, you just cause more analog to digital conversion to take place.

Yeah I tried the switching the VGA cable I was using. I may go pick up a DVI cable (I don't have one) and try it.

You are mistaken, your monitors native resolution is 1440x900 not 1400x900.

read the specs for yourself if you dont believe me. You should always run your LCD in its native res for everything. When you drop out of its native res it can cause problems cause it has to use multiple pixels to try and make one big pixel for a lower res. This can cause ghosting, blurring, shaky picture, etc. If you are at 1400x900 then im sure it is shaky as the display is trying to display an off resolution and is probably trying to auto adjust all the time since that isnt even a standard supported resolution of any monitor that i know of.

It was a typo. If I check my settings I cannot run it in 1400x900, its either 1440x900 or the next one down is like 1360x700, which looks like utter crap.

I've made sure that my resolution for control panel - display options is the same as my resolution for catalyst control center, and that the refresh rates match up. I rolled back to the drivers where I was not experiencing this, and its still happening, so I'm ruling it as the monitor getting worse. I can get a new one fairly cheap anyways I suppose.

Thanks for the contributions to trying to fix this issue.
