Subjective Analysis
For this portion of the benchmark, we will pit the UltraSharp 1905FP against the other monitors benchmarked in our 19” LCD roundup. 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
There were a few specifics that stick out to us with regard to this display. We were particularly disappointed that the intensity range and black level adjustment did not live up to some of the L1980U’s competitors. Even after compensating brightness and contrast in some of our trial runs, the darkest darks on the LG display just don’t stack up to the other displays – particularly Dell’s 1905FP, which is based on a Samsung panel. Samsung’s SyncMaster 193P is also based on the same Samsung panel and out-performs the LG L1980U in that regard.Perhaps we are just overly sensitive to the interpolation effect created by the 6-bit display, but this also proved to be a low mark for the L1980U. Granted, the difference between all of these displays is so miniscule in many instances that they have to be lined up next to each other to tell the difference. (Of course, at AnandTech, that’s exactly what we do). One visual analysis that we use to identify color intensity ranges is to display anti-aliased multi-color text on the screen of various sizes and thicknesses. On close inspection, there is clearly a noticeable difference between a display like the Dell 1905FP and the Flatron L1980U; the Flatron’s text comes out jagged, and even slightly distorted.
Gaming on the L1908U was right about where we expected. We didn’t find any fault with the response time of the monitor; the display was even a little more responsive than our Dell 2001FP (16ms TrTf, Super IPS panel). Response time is highly subjective to the user and while we feel that the display was quick enough to not detect any motion blur, our level of sensitivity may not be as high as others. When compared to a CRT display, the L1980U does not present the same level of responsiveness, but then again, no LCD does.
Like all LCD monitors, we highly recommend that only the DVI adaptor is used for this display, at least as a primary adaptor. For casual use, the 15-pin analog input seemed acceptable, although we could detect some minor distortion from time to time. The DVI signal was flawless.

I have used the LG1980U for the past two months and agree with the AnandTech review. The darks are washed out. I was also surprised by the narrow viewing angle especially from above the screen. However the display is not unpleasant to use and the exterior design is just wonderful. I was very concerned about blurring having previously used a CRT and I wanted an LCD with good response. This screen is fine. If exterior design must be visually appealing to you and accurate colour rendition is not vital then I highly recommend the LG1980U. I was able to purchase the screen for £350 and at this price have no complaints. It is excellent value.Micronaut - Wednesday, May 18, 2005 - link
We just got a 1905FP and it's HORRIBLE for gaming. The blur is very very bad. I cannot recommend it to anyone that has anything moving on the screen (and yes, I've loaded drivers, played with the vscyn, everything). :(Spacecomber - Tuesday, May 17, 2005 - link
The 910N sounds similar to the 910T, though Samsung lists the 910N's specifications as 250cd and 800:1, while the 910T's specifications are listed as 260cd and 1000:1. Both have 170/170 viewing angles. Perhaps these are the same 25ms PVA panel, but tweaked differently by the monitor's circuitry and backlighting. The main difference is that the 910N looks to be a budget version, in that it is analog only, while the 910T has a DVI connection. Perhaps the lack of the DVI connection has something to do with the lower specifications?(Just to make things more confusing, there also is a 912T, which is specified at 250cd, 700:1, and 170/170. This actually sounds closer to the 910N.)
Looking at Samsung's list of current panels isn't much help in sorting this out. They only list one 25ms PVA panel, the LTM190E1, which they specify as 250cd, 500:1, and 170/170. The only other PVA panel they list is the 8ms LTM190E4, which they specify as 250cd, 1000:1, and 178/178.
In any case, without a DVI connection, I think the 915N is destined to be an inferior monitor to most of the other 19" LCDs that you've reviewed, including the Dell 1905FP.

Space: I have a review of the 910N coming up - which I believe is identical to the 910T.You are also correct on the "overdrive" circuitry - although it is all the same stuff. Each company just feels like calling it something different.
JNo: Those ultra low repsonse times are unfortunately just hype. I can report a 4ms GTG response time, but that probably isnt the average and most likely a single scenario where the crystal is capable of twisting from one shade to another. Marketing seems to have gotten the best of that specification.
nserra: The interpolation is quite noticeable.

Someone offer up a comment on the Acer AL1914smd ... its available for $280 and seems like a great deal. DVI, 500:1 contrast and 12ms response seem like just what I want .. and its under $300. I can't determine whether its a 6 or 8 bit panel and whether that really, truly bothers me as a hard core gamer.LCDs ... about as confusing as wimmin during that 'monthly' thing .. *shrug*

How bad do these lcds look if one game doesnt run good at 1280x1024? And i have to go for 1024x768 or even 800x600.ElFenix - Monday, May 16, 2005 - link
yet another low resolution 19" LCD. is everyone blind that uses these things?Spacecomber - Sunday, May 15, 2005 - link
These low grey to grey response time monitors, I believe, are all taking advantage of this so-called "overdrive" circuitry. I think that it also goes by the term "feedforward driving", and apparently it was developed by Mitsubishi.This seems like one of those technologies that it would be useful for the reviewers to take a look at and try and separate out the facts from the marketing hype.
It may be that this is nothing that unusual and that it is being used in a wide range of LCDs. Perhaps some manufacturers have made a point about it just to dramatize their low response time numbers.

I know anandtech focuses a lot on the Dells and Samsungs in the LCD world (this review notwithstanding), which is in many ways fair enough given their marketshares, but there are other LCDs coming out which I'd like to see reviews of. I know response time isn't everything and is often a controversial subject but I'd love to see priority reviews on the reported 6ms Gray To Gray (GTG) BenQ FP91V+ and the reported 4ms GTG Viewsonic VX924. As #6 puts it, inquiring minds want to know....MrEMan - Sunday, May 15, 2005 - link
Does anyone know which OEM produces Dell's LCD monitors (I recall that some of their CRT monitors were manufactured by LiteON, but I have no idea who makes their LCDs)?I would be interested in how their retail monitors compare to the models they produce for Dell.
