Samsung S23A750D Viewing Angles and Color Quality

The Samsung is a TN panel but Samsung advertises improved viewing angles as one feature of the S23A (with the name "Magic Angle Vertical"); you can read about this and additional features on their product page. As you'd expect there's plenty of marketing hyperbole to be found, but in practice I did notice that the S23A has better viewing angles than competing TN solutions.

Most TN panels experience huge color shifts when viewed from the top or bottom of the monitor, and once they get past 20” or so in size you start to see the shift even when attempting to view straight on; by comparison, the S23A looks good when viewed straight on and I didn't see noticeable shifts from my normal viewing area. However, this remains a TN panel and when viewed from accute angles the shift in color and contrast is still present.

Unfortunately, while viewing angles are better than most TN displays, the pre-calibration Delta E numbers are as bad as we've come to expect from consumer displays.

With an average dE over 8 and some of the worst overall numbers occurring the grayscale, the initial numbers for the Samsung aren't very good. The result is similar to competing displays, but still disappointing. Let's move on to calibrated results.

Using the color settings to get the white balance as close as possible to D65 and then setting the brightness and contrast to get 200 nits of light output, I ran the calibration routine in ColorEyes Pro to see if the Samsung could perform any better.

The numbers for the Samsung are overall very good once calibrated. Not only do we get an average dE of 1.77, but the only large errors at all are once again in shades of blue, including the shade of cyan that falls outside of the sRGB spectrum. The entire grayscale spectrum is under 1.0 dE, and only 3 of the 24 swatches are above dE 3, which is the visible level if ColorEyes uses dE76 (which I’d assume, but can’t confirm). Hopefully in the near future we will be able to get all these results in dE94, which is more accurate for measuring color error. I also went ahead and did the same test, though at 100 nits instead of 200 nits, which is what might be used if you are doing print work.

Here the performance is almost identical to the 200 nits data. The grayscale isn’t quite as good, but still virtually perfect, and almost all the issue falls at the same three sample points. Overall the performance here was much better than I expected from a TN panel.

    The Samsung S23A750D is tested and certified by AMD to work with their cards in 3D, and so that is why it was tested with an AMD card. It appears on the AMD website as a supported device for 3D, but not on the NVIDIA website. Reading up on the matter showed that you can force it into 3D mode to work with NVIDIA cards, but at the moment it works more easily with AMD cards. Hopefully there is a unified standard soon so this won't be an issue going forward. Reply

    Samsung has had issues with touch for quite some time and I'm kind of surprised they still have not fixed it. I have used them almost exclusively since my first syncmaster 15 back in early 90's right up to the 2693 HM I have now and as far as picture quality I love them. The touch is horrible (all your same issues then some) and has always been a problem including several periods of time where it had a mind of its own. Nothing like being in the middle of a game and having it shut off or worse yet pop up the menu and go ape cycling menu's and changing settings at random. I still have occasional power button response issues but the menu cycling finally went away after I readjusted the front panel a bit by pulling it out around the touch panel. I have a much older Samsung 22" with real buttons and it is flawless to this day. Reply

    I'm not sure why you would have a non-gamer test what is obviously a gamer oriented monitor. I hardly think there are many people who would buy a 3D monitor to watch movies on. That's what 3DTV's are for.

    If Samsung wants to sell 3D monitors, they're going to have to make sure that everyone's current favorite games look great in 3D. Skyrim, Battlefield, SWTOR, etc. Unfortunately this aspect of the review was simply glossed over with small references to WoW and Half Life 2.

    If you enjoyed 120hz (I've been enjoying 120hz for quites a whiles now,) Sony is going to be releasing a 240hz gaming screen soon, which I have my eye on..... Although, in all fairness, you won't find many games that run >120fps these days, even if you buy top end hardware. I think the only way you're going to get this kind of performance, is through Source games (l4d, hl2 etc.) and the COD series.

    Wouldn't it be nice if they shifted their arses into gear, to develop a 120hz IPS screen? It's been nearly 10 years since CRTs were outlawed, and flat panel displays STILL haven't caught up in terms of all-round performance in one panel standard (colour reproduction, contrast, refresh rate etc.)

    I wish I could beat whom ever came up the 60hz is smooth. I can see motion up until about 90hz. Its subtle over 60hz, but certainly detectable. Back in the CRT days with larger monitors it was really easy to see this flicker in your peripheral vision. Reply

    Why is there no comparison to the Acer GD235HZ or LG W2363D, two very popular 23" 120hz displays. I own both and while the response times are very similar the input lag is miles apart. The "thrumode" on the LG makes it perform so close to a CRT I can't believe it.

    I use my 120hz displays for 2D desktop/gaming and the LG is the benchmark (even against a CRT, yes really) in my opinion. It's a pity this display wasn't compared to it's direct competition. I'd bet this monitor is best in 3D tests, but that's not how everyone uses them. The only way I care about another 120hz display is if it's 27" and has zero input lag like the LG.

    why was my comment deleted? It was on topic, well thought out, and made good points. That's just not okay. Reply

    I don't know where you arrived at nearly 12ms - the real figure for this series of monitors is around 4ms and I can say from experience they are as close as you can get to a CRT in terms of input lag. Reply

    Chris, even though I feel the rest of the guys here make a few valid points regarding the structure of the article and perhaps a bit on the technical side, there are a few things I think you should know:

    There are people like me, who would never use an Nvidia graphics card, simply because they a) just really don't like Nvidia and enjoy supporting the underdog (I know several of them) or b) people like me who absolutely require a silent PC. AMD are way ahead of Nvidia when it comes to the maximum performance of passively cooled GPUs and that is why I liked this article. I have been waiting for ages for an AT article regarding how AMD 3DHD folds out.

    While I know this is not a 3DHD in-depth review, the fact that you blamed the artifacts in the games on purely the monitor (it seemed that way), is a bit disappointing. There are also the IZ3D drivers. This article also has a mission of showing a glance of the 3D gaming capability of the monitor. It would have been nice to see you try another driver, especially since there's only -one- other. That might have given you a better experience.
