Samsung SyncMaster 915N: 8ms Response Times

Quantitative Analysis
For the duration of this review, we connected the Samsung SyncMaster 915N to a Radeon X800 Pro with factory default settings on the Analog connection unless stated otherwise. Brightness has been set to maximum as well (with the exception of some of the application tests). Our lab is set up in a controlled white room with two incandescent and two florescent light sources.Luminance
Brightness ranked as one of our most important display qualities. In a well lit environment, a bright display will actually offer less strain on your eyes than a dimly lit one. Below, you can see a comparison of the brightness for each of our LCD monitors.
Our Contrast Ratio
We will use the same observation from the 19" LCD Roundup several months ago. Using PreCal and our ColorVision Spyder, we will measure the luminance of a pure white image and a pure black image on the LCD monitor. The observed contrast ratio is simply the highest recorded luminance divided by the lowest. All measurements are in candela per meter squared; larger contrast ratios are more desirable.| Observed Contrast Ratio | |||
| Highest Recorded (white image) | Lowest Recorded (black image) | Observed Contrast Ratio | |
| BenQ FP931 | 256.4 | 3.6 | 71.2 |
| Dell 1905FP | 234.6 | 2.6 | 90.2 |
| LG L1980U | 254.6 | 2.8 | 91.0 |
| NuTech L921G | 278.2 | 2.6 | 107.0 |
| Planar PE191M | 234.0 | 3.0 | 78.0 |
| Samsung 193P | 230.4 | 2.2 | 104.7 |
| Samsung 910V | 219.8 | 2.6 | 84.5 |
| Samsung 915N | 264.2 | 2.6 | 101.6 |
| Sony SDM S94 | 233.8 | 3.0 | 77.9 |
| ViewSonic Q190MB | 261.8 | 2.6 | 100.7 |
Samsung actually doesn't perform too badly with regard to contrast ratio. Although our equipment is not particularly sensitive on the low light luminance recordings, the disparity between the Samsung 915N and the Dell 1905FP is more than apparent. The Samsung is the brighter monitor, but it cannot produce a dark enough of an image that many of our other displays can. You may recall that the Hitachi CML174B had very similar problems two years ago when it was the only 16ms display available.
With some applications, the "wash out" effect is slightly more prevalent on the SyncMaster 915N than on other displays. We use Dell 2005FPs almost exclusively for day-to-day operations in the lab, and going from one of those displays to the 915N is almost painful. However, when compared to the ViewSonic Q190MB and the NuTech L921G, the result is fairly comparable. The Samsung 193P and Dell 1905FP (which both use the same 25ms Samsung panel) lead the pack for 19" displays as far as real world comparison with the contrast ratio goes - even if the NuTech unit scored slightly higher in our Observed Contrast Ratio chart.

Okay so I'm looking for a 17"-19" viewable 8-bit 8ms LCD panel. Who makes them?(Getting tired of seeing reviews for 6bit panels.)

I'm having trouble understanding your contrast ratio chart?I assume higher white numbers are better and lower black numbers are better.
This panel has the second lowest black number (2.6) in you chart, yet, you don't like it and pronounce it "not dark enough".
I'm confused?

Keep the LCD reviews coming, since this is an area of computer products that is only going to continue to grow for the forseeable future. Hopefully, as reviewers get more familiar with these monitors they will be able to tease them apart the way they do when they discuss a motherboard or a graphics card, discussing the components that make up the product and how these have an impact on performance. Just as knowing whose chipset and what audio solution is being used on a motherboard tells you a lot about what to expect from a motherboard, knowing more about the panel and the circuitry being used with an LCD will eventually be a big tip-off as to what to expect from a LCD. Anandtech is already moving along this route by taking the time to disassemble and confirm what is being used in the constrution of the LCDs they review.As noted, the real competition for this monitor might be from the Hyundai L90D+, at least as long as it is using the same (presumably) panel as the 915N, since it does come with DVI. The other competitor that may make the 915N obsolete is the recently released Samsung 930B (as also noted above). Actually, a side by side comparison of the L90D+ and the 930B might be interesting, since it would allow us to see if we need to look a bit beyond just what panel is being used in a monitor and ask whether the supporting circuitry also makes a significant difference in final quality of a LCD's image.
(As mentioned previously, one of the disappointments for me in the Dell 19005FP, compared to the Samsung models, was the lack of ability to make adjustments to the monitor's image with the OSD controls. This really hurt the Dell 1905FP in my eyes, despite it using the same panel as the Samsung 193P.)
Finally, it might be worthwhile to look a bit more at the viewing angles when reviewing LCDs, especially when discussing TN panels, since my understanding is that this has always been a weak point for TN monitors.
You can see this in the specifications that Samsung lists for the panel used in this monitor (the link is given in this article in the first line of the page titled, Panel). On that page Samsung list the monitor's viewing angles as 75/60/75/75 (U/D/L/R), which seem more realistic than those given for the monitor, itself. Notice in particular how the when viewing the panel from below the viewing angle is less than from any other angle, this is characteristic of TN panels.
It seems to me that the narrow angles of a TN panel coupled with a stand that has very little ability to pivot (as with the 915N) could become a problem in actual use.

shiznit - he just recommended it in the latest buyer's guide and he just reminded you that he didshiznit - Wednesday, May 25, 2005 - link
if you want this exact same display but with DVI and pivot, get yourself a Hyundai L90D+, which has been out for some time and somehow anand never noticed.Zebo - Wednesday, May 25, 2005 - link
" However, as TN displays appear to be the only ones that can really offer substantially better response times than SIPS displays made by LG.Philips LCD"I've read every article at anandtech for four years and don't know what you're talking about... How about spelling out acronyms like TN and SIPS to make articles more inviting.:-)

I've been using my 193P for 10 months now. Still no reason to change, and the fact that I got it so long ago and still nothin' better (both looks and quality) has come out during that time proves to me it was a great purchase =)I really wish manufacturers would keep on designing stuff which looks like the 193P though. It probably doesn't cost that much more, and it makes a huge difference on the desk. This 915N looks like crap.

4 - Which is why I recommended the Hyundai in the recent Buyer's Guide. The problem is that Hyundai could switch panels at any time, which could suddenly make the L90D+ a poor choice. Anyway, 6-bit color isn't great, but for gaming the panels are really nice.IceWindius - Wednesday, May 25, 2005 - link
This is the same TN panel they use in the Hyundai L90D+ which I own and it totally freaking rocks!
