^ Nope, no problems with my DVI port, had the monitor for about 6 months now IIRC.
That being said, I know some folks are more sensitive to flicker than others so if it's at a very high frequency then I just might not be seeing it.
I do remember reading something about how some monitors control brightness by variably strobing the screen at very high frequencies... at high brightness levels the strobing is so fast that it's pretty much imperceptible (unless you're superhuman), however at lower brightness levels the strobing slows down such that it can be noticed by more sensitive types. Unfortunately the PA248Q is one such monitor that uses this technique, but FWIW I have my brightness set at 20 and still don't perceive any flickering.
Perhaps your flickering is happening at lower brightness settings?
You would think its a problem with the GPU but its not. Using any of the other inputs work fine. --- Corsair 500r ~ P8Z68-V Pro ~ i5 2500k ~ Hyper 212+ ~ Corsair 2x4gb ~ TX750w v2 ~ 560 Ti ~ F3 1TB ~ Crucial M4 128GB ~ Xonar DG ~ Tt Meka G1 ~ Asus PA248Q
At least the monitor has a 3 year warranty and rapid replacement where they cross ship a monitor to you free of charge. I'm just too lazy to do it right now. --- Corsair 500r ~ P8Z68-V Pro ~ i5 2500k ~ Hyper 212+ ~ Corsair 2x4gb ~ TX750w v2 ~ 560 Ti ~ F3 1TB ~ Crucial M4 128GB ~ Xonar DG ~ Tt Meka G1 ~ Asus PA248Q
As someone who's redgreen colorblind and can't ever tell if there is a 43 in that blotch test or not I'm glad I don't have to pay extra to enjoy a monitor. --- I think I'm the only person on gamefaqs with a daughterboard - ToastyOne New with a moderation history more plentiful than karma. - Fossil (Moderator)
One of the reasons why the iMac/rMBP screens look so impressive is because the don't have an anti-glare coating on top, it will be more reflective yes but it is also crystal clear. If you really want that clarity then I would recommend a glossy IPS instead of that Asus.
This is the reason I will never be using anything with anti-glare again http://www.overclock.net/content/type/61/id/954440/width/563/height/429
I am using the X-rite i1 to calibrate my monitor, no experience with any Spyder whatsoever but from what I have heard you will be fine with either.
What monitor (w/o anti-glare coat) would you recommend/have? I'm still leaning toward the Asus as it has less coating than the Dell, and is 8-bit instead of 6-bit. My computer will be in my 'study' with a darkened window. The amazon prices for the Asus are about $50 more than the Dell but that's minimal. --- http://zengraphics.webatu.com
