LG L1930B... IPS?

  • Hi. I'm looking for an LCD monitor to replace my CRT. I would use it mostly for surfing the web and although I'm not a big gamer, I do play games every once in a while so it has to be fast enough to play mid paced games without too much blurring. Originally, I wanted the Samsung 193P but since it has a PVA matrix it's probably too slow for anything. At work, I use a Benq LCD which has a TN panel and while it's an OK monitor, I hate the narrow vertical viewing angles that make the top of the screen look darker than the bottom. So, I figured I need a monitor that uses a S-IPS panel. Now, 20" inchers are too expensive for me so it has to be 19". I was looking at the LG L1930B which I can find for a very good price but I don't know for sure what panel does it use? Is it S-IPS or MVA? Also, does anyone own this monitor that could tell me how it performs in games and how is the image quality in general? Thanks.

  • Refering to our Database the LG1930B has an S-IPS Panel. For your purpose it is surely qualified.

  • Thanks. Just a couple of more questions: I know IPS panels have a poor contrast ratio, but how bad it really is? The benq that I use has a TN panel which are known for poor contrast ratios as well but although I can see the blacks aren't truly black, it doesn't bother me THAT much. My question is, are IPS panels actually WORSE than the TN ones in this regard or they are the same?

    I've seen people complaining about some "crystal effect". What is that? Is that the same as the "screendoor effect"? Also, am I correct in saying that a 25ms IPS is much faster than a 20ms PVA?

  • Contrast ratio/black level:
    All LCD panels included IPS panel types are characterized by a remarkable higher contrast ratio than CRT monitors. Usually every TFT monitor provides more han sufficient contrast ratios. Of course, more is better.

    The contrast ratio doesn't say anything about black's reproduction. It just is a value between the lowest and the highest brightness the screen can show. Black level is generally weakness of TFT monitors. Most CRT monitors shows a deeper black that TFTs.

    The panel type itself has no influence to the black level. But you can see in average cheaper TFTs, which contains often a TN panel have got more problems with illumination uniformity than expensive ones (with IPS or VA) because of worse housing contruction and backlight assembling. Bad illumination uniformity has worse impact to black level reproduction, therefore its results in only a dark grey. Thus the probability of a good black is higher for TFT Models with IPS/VA panels, but there is no guarantee.

    Crystal / screendoor effect:
    The "crystal effect" is special for LG S-PS panels. It seems like a soft glint or glimmer of the panel surface. A few users don't like it, but most haven't got any problems with it. The screendoor effect is different. In that case the panel shows stripes because of missing uniformity brightness of the pixel lines. Also this effect is special for LG S-IPS panels.

    Response times:
    In general a 25ms IPS is faster that a 20ms VA panel and thus more suitable for gaming. The responsibe times of the TFT specifications just shows the time between switching black/white/black but not between any colours between. Here VA panels are quite worse the IPS panels.

    If it's just a value between the lowest and the highest brightness the screen can show, it does say something about the reproduction of blacks doesn't it? I mean, I've seen some PVA monitors like the 172T and the black is much darker than on any TN + Film panel I've ever seen. I have also used a Samsung 172X which is not really a cheap monitor and blacks were much brighter due to the TN matrix (or at least I believe so anyway). Tomshardware measured the level of black of the Samsung 193P and it was only 0.19cd/m2 which means the backlight luminance is practically invisible when showing black screen.

    What do you think is the better monitor, Samsung 193P or LG L1930B? I was leaning towards the 193P but the catostrophic response times on grey-to-grey transitions puts me off the PVA panels. Now that I've heard about the crystal effect problem on the LG I'm not sure what to do anymore ?(

    The contarst ratio only specified the difference between the brightest and darkest grey value be able to show. Thus the same ratio value is valid for shining white and dark grey as well as very bright grey and deep black. Therefore the ratio give you not a dedicated information about the black level, but a TFT has probably a better black if the TFT ofers higher contarst rations, that's right.
    Consequently PVA panels in averag shows better blacks than TN ones.

    I am myself really not a big gamer, I am am still quite happy with my slow 1980SX (PVA inlcuded). Its hard to advised you a TFT model, if you don't now how slow response times and/or crstal effect lokks like in reality. The impression of such kind of optical effect strongly differes individually user by user. I assume, that slow response times can probably more bother you if required for games that the crystal effect, if I summarize the TFT users opinions here in the board.

  • I have the same dilemma between LG 1930B (S-IPS) and Belinea 101920 (PVA). Basically I use my computer for internet-office (40%), fims (40%), photo editing-webdesign (10%) and games (10%).

    P.S: I was told that a lot of LG's monitors have pixel problems. Is that true?

    I apologise for my English :)

  • What kind of games do you play?

    Pixelproblems? You mean dead pixels? That is not true. Pixelproblems can happen to every device.

  • Yes, I mean dead pixels.

    I usually play strategic games, football games, sometimes rally games and rarely FPS.

    I know that S-IPS panels is better for allaround use. So I'd prefer to buy that one. On the other hand I read in other Totamec's posts that the build quality of LG's monitors is not the best.

    I am sceptic about Belinea's support in Italy and in Greece (I'm greek but for the time being i live in Italy). Maxdata products are not used a lot in these countries, so I don't have any experience with this company.

    Thanks for the reply :)

  • First, we had some problems with links in signatures, can you please remove them? Thank you.

    You really need an IPS device. Can´t you get a NEC 1960nxi, Iiyama 481 ? They have a better quality.

  • Thank you :)

    Give me a link to a shop were you want to buy and we will take a look for what they have. Don´t care about the language! ;)

  • These are the link for the eshops I have found with "good" prices. Let me know which monitor you suggest to me. Thank you very much in advance :)

    Budget max 550 euro.

    Why should I buy a S-IPS monitor? Because they are allaround panels?
    Which is the reason I have to avoid VA panels such as Belinea?

  • For your main use cases internet-office (40%) and films (40%) VA-based as well as S-IPS based TFTs are adequate solutions without any restrictions.

    For photo editing-webdesign (10%) and games (10%) the situation differs. If colour accuracy is most important for the first use case S-IPS panels are better suitable. Only the first imprsssions is not as brilliant as of VA panels, because S-IPS contrast ratio is farther low compared to VAs but anyway more than sufficient.

    Also S-IPS panels offers the overall faster response times for games, especially 3D-shooter and similar ones.

    Thus - you have just to aviod VA TFTs deppending on your profession of the use cases games and webdesign.
    For example: If colour reproduction is not deppest improtant and shooters are not your couple of tea, VA panels are as well a good choice. If not, they could also annoy you..

  • Thank you very much Weideblitz for the explanation :)
    I have to make myself clear: When I said 10% photo editing and webdesign I meant occasionaly and not at professional level (I'm a university student).
    I will wait for Totamec's proposal, about wich monitor should I buy, from the links above.

  • So, as you said, if you play games, than mostly strategic games. Therefore I would propose you the Belinea 101920 mit PVA panel, as long you do not have the possibility to buy a NEC 1960SXi or an Iiyama 481. If there is any chance to look at that monitor before buying, take it to create your own impression. ;)

  • Yes I mostly play strategic and football games (PES 4), when I rarely decide to play a game and almost never FSP.

    Finally, I have ordered Samsung 910T, which should have the same panel as Belinea but I am sure for a better after sales support in Greece and Italy. Also maybe it has better eletronic parts than Belinea as well ?(
    I have found it only 35 euros more expensive than Belinea, so I decided to buy that one (Samsung).

    I have seen Samsung's 192V panel. I don't know if it's the same, but it should be a similar PVA panel. Do you know if they have the same panel?

    Thank you very much for your help ;)

  • That' also a good choice.
    Yes, I guess both panels are identical. Probably the electronics differs, because the 910T offers more options, e.g. colour management.

    I would look forward to read your experience, after you got and tested your TFT. ;-)
