LCD monitor question

Postby DelPen on Thu Feb 09, 2006 11:03 am

So my 17" CRT which was 8 years old died. Got a new 19" LCD yesterday and it's great. Except when the background is dark, like this site, it has a weird buzzing sound. It's not too loud but if it's quiet it's noticable. Anyone know what is casing this?

Just did a quick search and there are others with that issue. What manufacture/model is it? How easy would it be to return it?

Just out of curiousity, when you crank up the brightness a bit does it go away?

It's a Westinghouse I got at Best Buy so it should be very easy to swap and return. I'm using the onboard video but I am going to try a Radeon 32MB AGP card and maybe even try the DVI connection after installing that if I can find a cable. Adjusting the birghtness didn't really do much either. I also have only two refresh rates come up on auto detect, 60 and 75. Tried both, no difference. I also searched for drivers but found nothing on the Westinghouse site.

It's a shame, the whole thing was $300 including tax and looks great, no dead pixels, good color and brightness. Just a very low buzzing. I'm betting it's the video adapter though, at least I hope.

I used to have a monitor that was shielded so poorly, that the frequencies of the monitor and light would play hell on each other, with the light strobing and the monitor making a quiet screeching noise. ;-)


Nope, it's completely fine with a light back ground and the buzz only comes up when the background is very dark, like this site. You ever get a buzz on your TV when the picture is very, very white and bright? It's like that but reversed and not nearly as loud.

I know, I took it out when I was having some power issues with my USB WiFi and never got around to putting it back in after I switched to a PCI WiFi card.

I still prefer CRT monitors to LCD....

OK, so the new AGP card did not fix it. A DVI cable did not fix it. A replacement of the same brand did the same thing. So Westinghouse sucks. I'm glad I found this out on a $300 19" LCD before I migth have spent $3000 on a 37" LCD HDTV.

I exchanged it for a MAG Innovision from best buy, 19", analog only but no weird noises and it's a decent monitor for the price if anyone needs a 19" LCD on the cheap and wants to go through an actual store and not roll the dice online.
