Possible problem with my 710N LCD

[TheGreenGoblin]

I got myself a Samsung 710N last week and I've noticed some "waviness" for lack of a better term. When set to 1280X1024@70hz I can notice lines of slightly different contrast moving diagonally from upper left to bottom right or vice versa.

It's noticeable on web pages with a uniform color background and it only seems to happen when set to 70hz ,at 60hz I never see them. It's intermittent , the waves might appear for a few seconds then fade out , then reappear a few seconds later.

Any other 710N owners notice something similiar? This is my first LCD and I'm quite happy with the image quality but this effect is slightly annoying.

Have you tried 75hz?

I had my old CRT set to 60hz, and unless I'm mistaken, I swear I saw in the manual on the CD that I'm to run this monitor at 60hz. I was having some issues with text showing up looking like crap along with some pretty pathetic shading and color display. The main issue with the text is that in half inch increments it would look fine, and then look "fat" from left to right from one side of the screen to the other.

Then I saw on the box the monitor was sent in that it's to be run at 75hz. I set it to that, and now it's beautiful.

LCDs are supposed to be set at 60hz, normally. Setting it higher potentially is damaging to the LCD. Set it to what its supposed to be, which is 60 or there abouts. LCDs don't refresh like CRTs. Its a dot per dot refresh, not line per line. That's why you're having problems at 70hz. Go lower, not higher for LCDs.

60 hz doesn't work with this monitor.

Hmm, what is it supposed to work at? The manual should say yadda yadda, don't set it above yay refresh rate. And the op says himself, at 60hz, he doesn't have the problem...

I don't have the documentation in front of me at the moment... I'm at work on my lunch break.

But the box the monitor came in says "optimal 1280x1024 @ 75hz." What's odd is that when you install the drivers you have to deselect the check box that says "only display monitor supported refresh rates" to get 75hz to show. Personally, I think this is a glitch in the drivers.

Since my documentation is at home I'll have to wait to go through it again to see what it says the recommended refresh rate should be. But since it says 75hz on the box, and I have a three year warranty, I feel pretty safe in running at 75hz. Especially since the monitor really doesn't like any of the other settings.

Alright, I know this isn't much, but scroll to the bottom of the page and read the second to last paragraph...

I've been running searches on Google and it seems that others are having this same issue.

The driver won't let me set it to 75 unless I uncheck the "Hide modes that the monitor cannot display". I'll try it and let you guys know if the problem persists.

And according to the setup guide , 75hz is the recommended refresh rate for this monitor.

Thanks for the help Mykl. Looks like you were right. 75hz is fine. Damn driver

Glad I could be helpful.
