Samsung S23A750D 3D LCD Display

Most TN panels that I have seen seem to have uniformity issues around the panel, but this is also probably that TN panels are usually found in less expensive monitors that use less expensive backlighting systems. The Samsung isn’t an inexpensive monitor and has much better uniformity than most panels out there.
Other than the bottom of the display, the Samsung is as uniform a monitor as I have seen so far, and maintains its low dE across most of the screen. Samsung has done a much better job with their TN panel and color uniformity than most vendors out there. That darker lower-right corner doesn’t seem to cause much of a color shift at least, as an uneven backlighting system often can.
Despite only being listed as covering the sRGB gamut, which would mean 71% of the Adobe RGB gamut, the Samsung measured out to cover almost 78% of the Adobe RGB gamut. Compared to a normal sRGB monitor, most of that extra range seems to be in the additional blue colors that are available. As one of the samples used to calculate the dE value that is blue is typically outside of the sRGB gamut, the extra gamut can bring the Samsung closer to being able to display this color, which helps the overall dE.

I agree. I probably wouldn't have said anything for fear of coming across as a douche, but since you said it first I feel a little more justified. It reads like a high schooler wrote it, or an educated ESLer.The0ne - Tuesday, December 20, 2011 - link
As I've said before, the reviews here are better than most places but they are still written for the masses. In this respect they are meant for the common, average Joe. Writing a technical review or article is nothing like this, I should know I do this for a living. But if they were most people would probably fall asleep. Might as well pick up a technical journal or magazine. Some people are glad it's not like that and some people are not.Blogging mixed with technical reviews is a touchy subject and while I don't really like them I can live with them knowing that they are not meant to be the same as what I do for work.

Any chance you have a Mac with Displayport there?I'd love to know if a display like this will work at 120Hz on a Mac.

I did hook it up to my Macbook Air (I hook everything up to my Air actually), and it ran at 120Hz just fine I believe. I can't check anymore, but I believe with 99% certainty that it did.tzhu07 - Saturday, December 17, 2011 - link

If I wanted to have a mirror to shave with I could get a mirror a lot cheaper than $400. I've switched over to my tablet for most things because I find all these reflections very annoying.cheinonen - Saturday, December 17, 2011 - link
It could be dependent on how it operates at 60 Hz vs 120 Hz. If it runs at 120 Hz when fed a 60 Hz signal, but just repeats the same signal twice, you would expect identical results. If it runs at 60 Hz, the decay time could be slower than 120 Hz possibly. It's unlikely, but without being able to test both, there is no way to know for certain.Conficio - Saturday, December 17, 2011 - link

Is there a technical limitation that prevents an IPS panel from displaying 120hz? I can never go back to TN panels...ananduser - Sunday, December 18, 2011 - link
TIME...that is the limitation, be patient, soon 120Hz IPS will be available. :)
