Looking at it from normal distance I see no dead pixels. But I don't really know how visible a dead pixel is (?). When I make the a 100% white image and put it full screen and look very very closely, I can count 11+ tiny dots that either flicker a bit or are black. Dead Sub-pixels? Anyway there are no problem.

Maybe it is dust on the surface? Sometimes dust any real defect pixels looks the same.

Anyway searching for dead pixels needs displaying not only white, also black, red, green and blue. Pixels, which constantly shows everytime the same colour are full dead pixels. If they shine only in some of it and not all, that it's a dead sub-pixel.
But anyhow, if it they not bother you, maybe it is better not to search something for.

But some problems show..
Button for Auto configuring the screen gives only a OSD message "digital video input no access". And I do have this connected with DVI-D cable.

Also they were no drivers of any type on the cd's and there is no downloadable drivers for photon19vision on LaCie website. I now have set up as "Plug and Play monitor". Windows doesn't regonize it as anything else.

Usually you don't need any monitor driver. It does not make anything better any it will not solve your problem.
I assume, that the DVI port of you grafic board is not activated. To do that, you have to go in th setup of you grafic card driver and activate the digital output. After reboot the LaCie should react on the DVI connection.

Also consider to output digital DVI only at 60Hz. TFTs don't need higehr frequencies.
Also some TFTs can be disturbed by conecting both the analog DSUB and digital DVI at the same time. But usually only TFTs can be affected by this, if they don't offer a switch button between both inputs or a similar option in the OSD.

I hope, I could help you a little.

If you want to buy the Sony HS94, please consider the mirror surface of this TFT. In rooms which lights below the ceiling the reflections can be very annoying. However, many users like impression of higher contrast and stronger colours, which results because of the shining surface. In fact this TFT is nothing for office areas.

For my point of view the view area of the Hyundai is too small. 135° in vertcal direction is visible below the 160° of the Samsung. Maybe it will not bother you, only you have to decide it yourself.
The Hyundai leads in features, but I assume, that the lack of view area is more strong to see than the difference between analog DSUB and digital DVI (if you have a state-of-the-art grafik board).

For my point of view most statements in the review are near to the reality. There are quite lots of TFTs worse the Samsung. If Samsung inside this Dell, I don't think you make something wrong - except, if you are a hardcore gamer..

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.

Das kann mehrere Ursachen haben:

a) Die Grafikkarte. Ausgefraste Grafikdetails bei Bewegungungen können ein Treiberproblem darstellen. Da hilft nur ein Treibertausch, falls es überhaupt einen neueren gibt.

b) Möglicherweise laufen andere Applikationen im Hintergrund, die stark bremsend auf das Spiel einwirken.

Ein TFT Problem kann ich mir so noch nicht darunter vorstellen. Typischerweise tritt ein solcher Effekt eher auf, wenn die Grafikkarte der Darstellungsgeschwindigkeit auf dem Monitor hinterherhinkt.

es gibt doch die S-IPS panels mit 17" in 16ms und auch die 20" S-IPS mit 16ms.
warum gibt es dann keine 19zöller? kann mir das einer erklären?

Keine Ahnung, möglicherweise sind diese für den Massenmarkt zu teuer um in geeigneter Qualität hertgestellt werden zu können. Und 20" TFT mit S-IPS sind auch heute nicht gerade ein Massenprodukt.

Quote

und hat ein S-IPS panel wirklich alle 16,7mio. farben oder wird da auch interpoliert wie bei TN panels.

Üblicherweise ja.

Quote

und gibt es irgendwo ein test der reaktionszeiten über die ganze farbpalette hinweg? also rot, blau grün, grau?
würde gerne wissen wie schnell so ein S-IPS im durchschnitt ist im vergleich zum TN.

Nein, die gibt es nicht. Jede Panelbauart und auch jedes Paneltyp hat einen etwas anderen charkteristischen Reaktionszeitverlauf. Daher liefert der reine Durchschnittswert keine Mehrinformation.

Well its not like it has explicit names. DV-Mode OFF, DV-Mode 1, DV-Mode 2, DV-Mode 3. The manual tells these different modes are meant for working with text, video watching etc...but it does not specify which is for what exactly. I guess we will need another NEC user for this one

As I found on NEC daatsheets they call it "Digital Visual Modes" but there is no detailed explanation about the technical background of this feature. Anyhow I guess, that this DV-modes are presets of gamma values. My 1980SX doesn't offer DV-modes in its standard menu (also not in the advanced menu), but im the advanced menu I can change the gamma values free as I prefer. There are also presets called "No correction", "2.2"; and "S-Curve". I assume that's the same.

Also, I would like a program that would provide me a fast way to change between different contrast & brightness profiles. Neither the monitor software (Naviset) nor my graphic card drivers (Catalyst) provide me with this function.

Have a look at to the brightness controller tool from NEC: [/URL]

You can not freely setup own profiles for brithness control, but you are able to distingish the brightness setup between different types of applications.

Hopefully it helps you.

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..

No, unfortunately not. But taken experience with old Samsung TFTs and users opinions into account the 920T is a good choice for everybody how whats a PVA panel with its pro & cons.

The 920T offers features like changeable interpolation modus and rotateable foothold the 109020 doesn't have.

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?

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.

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

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 believe *VA has strong, saturated colors, but when it comes to color *accuracy*, S-IPS is probably better.

What do you guys think? Am I wrong?

You are totally right. Colour quality contains of some different aspects, whioch has to be considered.
If the colour "shining" is the most important one, VA panels are the best choice. The offer the highest contrast ratios, which are responsible for luminous colours. For most users colour quality is evaluated at first at this aspect, because it is very fast to see.

Photographers and especially everyboy in DTP and other colour reproduction jobs needs screens with high colour accuracy. That meens, that green is really green, red is really red and blue is really blue. At this job IPS panels are superior to VA panels.
Furthermore: IPS panels shows are bigger colour space/range of colours. Only the best (and most expensive) TFT models like the EIZO CG-series offers colour spaces which are compareable to CRTs. Consumer TFTs only provide a limited colour space, but for general applications this is no big restriction.

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.

Vielleicht medelt sich dazu noch mal ein HS94P-User zwecks Nachvollziehen. Ansonsten würde ich dann mal den Sony-Support bemühen, denn dazu fällt mir jedenfalls nichts weiter ein.

Versuche mal, den TFT und PC nacheinader anzuschalten in beiden Varianten, ob sich dann etwas ändert.

Edit: PixPerAn muß man nicht installieren -- man startet es einfach

Danke für die Blumen.

Entpacken und ins richtige Verzeichnis kopierten ist auch eine Art der Installation.

Hallo Montecore,

sorry, wer lesen kann, ist klar im Vorteil.

Wenn der DOS-Modus auch nicht funkioniert, gefällt deinem TFT die Wiederholfrequenz bei VGA-Auflösung nicht. Der TFT sollte auch unter Windows mit 60hz angesteuert werden. Wenn die Frequenz höher ist, könnte es ggf. sein, daß der Treiber bei VGA die Frequenz nicht angepaßt.

Dies würde sich erhärten, wenn du im abgesicherten Modus von Windows unter DOS nun ein Bild bekommst. Dazu muß Du wahrscheinlich auch erst mal den alten CRT dranhängen, um Windows in diesem Modus hochfahren zu können.

Eine andere Möglichkeit besteht darin, den Radeon-Treiber gegen einen aktueller Version auszutauschen. Möglicherweise ist er buggy.

Ich denke, du must den Treiber für den Grafikchipsatz nachinstallieren. Gemäß des Bildes werden dir ja 32-Bit Farbtiefe vorgegaukelt, was aber nicht zu stimmen scheint. Standard VGA-Treiber (ich vermute, daß dieser gerade läuft) vermag die Grafik-CPU wohl nicht korrekt anzusprechen.
