I bought a new 20" Widescreen acer monitor a couple months ago. I love it but my only complaint is that when it displays dark colors, it's kind of wavy looking. I was thinking this might be the refresh rate being set too low, but when I go to change it my only choices are 59hz and 60hz. I even unchecked the box that says hide values not supported. I have the latest drivers for my video card, which is an ATI Radeon X1900GT. Here is a link to my monitor on Newegg: http://www.newegg.com/Product/Product.aspx...N82E16824009108 . Thank you for reading this, I really appreciate it!

I would suspect it's a video driver issue. Try rolling back the driver

LCD monitors are not affected by refresh rate settings. In fact, setting the value higher than 60hz can damage some monitors.

What type of cable does your monitor connect with, dvi or vga?

DVI looks like this:

VGA looks like this:

Im not sure I understand exactly what you mean by "wavy" Do you mean the image "waves" on the screen, i.e., that the wave is moving, or do you mean that the geometric accuracy is poor?

Thanks for the replies! I realized the link I sent is to the wrong monitor. That model is an AL2016WBbd, while mine is a AL2016WBb. Mine has the same specs, but only has a VGA port and no DVI.

My monitor uses VGA, but to hook it up to my graphics card I have to use a VGA-DVI adapter.

By "wavy" I mean that on only dark colors like black, dark browns, and dark blues, you can see slow moving waves, going in a certain direction. The waves look exactly like waves in water. It's like the lcd fluid, or whatever is in it that produces the picture, is having a pebble thrown into it and the rippling out is what I see. The waves are not different colors then the color that section of the screen is suppose to be displaying. I tried taking a screen shot, but there were no waves, so its a monitor problem.

It only happens on dark colors. Right now since this website is mostly white with some blue, I don't see any waves at all.

This isn't a big problem, but it would just be nice to fix it.

I'll try rolling back my drivers too.

Do you have another VGA cable you can try? Try moving the VGA cable away from power cables, or other transmission wires, as this can degrade VGA's preformance. See if moving the cable around changes the bad effect. Most vga systems cannot take resolutions above SVGA (1280x1024). Therefore, your cables need to be unusually good for your monitor, which is 1680 x 1050.

If moving the cable helps, than we have found our problem :thumbsup:

Thanks for the reply! I tried moving the cables around, but it didn't really help anything. I then started messing around with the different monitor settings, and I found one that makes these waves less noticeable. I think I'll just leave it how it is.
