Subjective Analysis
For this portion of the benchmark, we will pit the SyncMaster 915N against the other monitors benchmarked in our 19” LCD roundup and comprehensive 19” display reviews since then. This is a subjective test that relies on our overall experience with the monitor after several hours of casual and thorough use. We also use test patterns and guidelines from the VESA FPDM to rate each unit as fairly as possible.Here is generally how we rate a category:
5 - Outstanding; we have not seen anything to date that could rival our impression of this monitor's performance.
4 - Good, but room for improvement. There are units on the market that perform better.
3 - Average; this monitor performs well enough to maintain the status quo, but does not excel.
2 - Improvement needed; this monitor performs poorly in performance of this category.
1 - Unacceptable; this product does not pass even basic performance requirements.

Note: the streaking/ghosting mentioned in this portion of the analysis refers to streaking and ghosting as interference, not as a byproduct of poor response time.
Notes from the Lab
As we somewhat suspected, the real weak points of the display line up with the intensity range check and black level adjustment. LGE recently had similar troubles with their L1980U (6-bit TN) display as well. When compared to the L1980U, Samsung clearly had an edge on color reproduction. Part of this may be due to Samsung’s slight change in the TN mode itself, but more likely has to do with the color interpolation – which does not use a square matrix like many of the other TN displays that we have seen. This image quality is not flawless, of course. Even though the interpolation might be slightly better than other 6-bit TN displays, some of the same issues with text present in the L1980U are present in this display as well.The other low point for the SyncMaster 915N is the analog only cable. Dell uses expensive, but versatile Genesis digital signal processors for all of their displays. As a result, almost all of their displays are capable of multiple inputs and, at the very least, DVI and analog. Samsung displays very commonly have DSPs that are custom designed just for that display, and tacking on a DVI input isn’t just a matter of plugging the interconnects into the chip. In any case, we appreciate the fact that Samsung gave us so many levels of control in the DSP, like sharpness and coarse adjustment, but a DVI interface would have done this display a lot of justice. There were several instances while playing games where we could pick up small artifacts along the edges of the screen, and this anomaly seemed dependent on where the analog input cable was positioned on the desk. Analog interconnects need to disappear off the face of the earth, and fast.
Gaming was one of the better qualities of this display. Since the colors seemed accurate enough and wash out occurred infrequently, response time became the focal point of the display again. World of Warcraft and UT2004 received a noticeable boost in performance when rotating the camera. Motion blur was considerably less on the SyncMaster 915N when compared to the Dell 1905FP. One way to really differentiate this display from a display like the Dell UltraSharp 1905FP was to rotate the camera, but leave something in the center field of vision. LG’s L1980U performed great in this category as well, but the fact that the SyncMaster 915N came out ahead in several other tests really sets it apart from LGE’s alternative.

Neogodless, I think they do qualify their objective analysis by saying that their equipment doesn't do a very good job of measuring the blackest blacks. This means that the black measurements are somewhat misleading; they appear to be more similar than actually is the case. In actual use, the difference is apparent. The monitors that have PVA panels (Samsung 193P and Dell 1905FP)and even a IPS panel (Dell 2005FP) reproduce something much closer to true black compared to what the TN panels are capable of, regardless of what the "spyder" says.Space

"The Samsung is the brighter monitor, but it cannot produce a dark enough of an image that many of our other displays can."The only display with a lower black image reading was another Samsung (at 2.2). Please explain!

LX, Samsung has a 19" panel, LTM190E4, http://www.samsung.com/Products/TFTLCD/Monitors_n_... , which appears to have the same specification as the LTM240M1 that you mentioned (except this this 19" panel does not use a wide screen format).I believe that this LTM190E4 panel is what is being used in the Samsung 193P Plus or 193P+, http://product.samsung.com/cgi-bin/nabc/product/b2... . But, I don't think this monitor is widely available (yet?).
I'm eager to hear, myself, whether any PVA panel, even with a 8ms response time, really is suitable for dynamic images, such as in gaming. The problem with PVA panels to date has not been that their white to black response times (which is usually the specification given) are that high, rather it is that this measurement doesn't convey how poorly PVA panels do with more subtle black to grey or grey to grey transitions. Unfortunately, a relatively low black to white response time doesn't necessarily mean you can expect a similar improvement in the black to grey and grey to grey response times.
So, I remain interested in learning more about these 8ms PVA panels, but I'm also skeptical of them, until I see a thorough review done.
(The Eizo L778 is another 19" PVA based LCD that sounds like it might be a relatively low response time monitor, at least based on the specifications. I'm not aware of any thorough reviews of it, either.)

I posted this in the previous LG review, but I don't recall seeing an answer: does anyone know who builds Dell's LCD monitors, and how do their retail versions compare to the OEM version produced for Dell?LX - Wednesday, May 25, 2005 - link
The Samsung LTM240M1 panel used in the Dell 2405FPW has excellent specs:http://www.samsung.com/Products/TFTLCD/Monitors_n_...
Unfortunately, 24" wide screen (1,920 x 1,200) is not the best choice for crowded workplaces, mid-range graphics cards and/or tighter budgets.
Are there LCD monitors that use panels with comparable specs but smaller sizes?

This was a great review... I own the 930B (the newer version of this screen with the DVI input. Also, no one has noted this about the 930B yet, but one other thing the article had on it's wish list (software to control the DSP settings) is included with the 930B. The 930B is an awesome display, and since I got it for only $320.00 (and there were 2 mail in rebates for $80.00 on top of that) at my local Fry's, I could not help but buy it. I love the damn thing! Also, this is the first LCD I have ever had (I have owned 6 of them before this one) that does not have even 1 single dead pixel. Great job on a great screen Samsung!!WT - Wednesday, May 25, 2005 - link
19" LCD reviews = HAWT !!! (as Paris would say)Keep them coming .. these things have become the new Ipod and every semi-hardcore PC user I know is contemplating an LCD purchase. I'm buying one myself in 3 weeks (leaning towards the Fuji FP-988D).

yacoub, what you are looking for is a LCD that uses a IPS panel (In-Plane Switching). All the TN panels (Twisted Neumatic) are only capable of 6 bit color, and all the PVA (Patterned Vertical Alignment) monitors will have too slow a response time, especially once you get away from only talking about black to white transitions.Unfortunately, the IPS panels are pretty much only found in 20" displays (and larger), such as the Dell's that RaidenSix mentioned.
Perhaps as consumers become better educated about the limitations of "low response time" TN panels, there will be a growing demand for better quality monitors, such as those built around an IPS panels, in a greater range of sizes.

yacoub, you can look at the Dell monitors (2001FP, 2004FPW). You can get them at a good price with their coupons.
