| Is it normal to see extreme pixellation and that which I think, but am not sure, is called "rainbow effect" on a brand new LCD monitor (Benq FP71V)? I'm considering returning this monitor and get a CRT again, but before doing that I'd like to know if this problem can be remedied by tweaking some settings or by simply getting another unit because this one happens to be defective. Thanks! |

Did the cable come with it?
Are you trying to extend the cable with an adapter cable...the reason I ask is that when I hooked up my LCD monitor it did similar... I was fearing that I would have take it back until I replaced the extender cable that I was using with a previous monitor. I replaced that extender and the LCD worked like a treat every since.

A LCD monitor only work well at is native resolution. You check the box or the manual if it says max resolution 1280x1024, you go into your display property and you set it at 1280x1024. Everything else will look like sh...
As for the "rainbow effect", there's no such things in an LCD monitor because, unlike DLP projection television, both RGB color are displayed at the same time. That said, what you see is probably some kind of moiré effect. When you run a LCD screen at lower resolution than it's native, The screen have to "scale up" the image for you to see it, resulting in artifacts like pixellisation and moiré.

| Thanks for the replies. I should have given more relevant info. The monitor is running at its native resolution, which is 1280x1024, and connected to the computer with its own cable; no extender or anything like that. It's also been calibrated with a Spyder2. Pixellation occurs particularly in mostly featureless single-color or gradient-color areas such as the sky, and it's an ugly sight. Additionally, the effect is gone when the image is resized to smaller than about 1000px on the long side, however it's very much visible in RAW files and full-size PSD/Tiff/Jpeg images. |

| Ah... I see... Shouldn't be that way. How does the desktop look? Is it crisp or is it pixelated as well? |

I don't know what LCD model you have but most of the ones I saw doesn't respond well to high saturation and gradient...

Everthing other than my photographs that have clear, blue skies look fantastic. In fact, I was very impressed and happy with the monitor until I opened a RAW file and saw the horrid pixellation. Well, since I can't afford an Apple Cinema Display that everyone raves about, I guess I'll have to be content with a new, decent quality CRT for now. |

alot of displays say they support 16.7 million colours but will only display 18bit colour.. so if you have a gradient then it will more than likely be dithered..
