Samsung SyncMaster 570V TFT 15" Flatscreen Display
Samsung SyncMaster 570V TFT 15
Abstract: The 570V shows a nod towards the impending power crisis which is gripping areas like California with rolling black outs and power shortages.

The Details are in the display

The display on the 570V TFT is very sharp and very bright. Bright colours are vibrant, and black backgrounds are even and dark (contrast is 250:1 and brightness of 200cd/m2). This contrast value as we mentioned previously defines how dark the darks are and how light the whites are. If the contrast is low, everything is somewhat dull. With a high contrast, black and white characters when placed next to one another are very highly defined. Typical contrast ratios sit in the range of 150:1 to 300:1. From what we've seen in the past on other TFT displays anything above a contrast of 100:1 is pretty much fine in an darkened room. Where the differences stick out is in bright rooms, where the lower contrast display's can sometimes appear dull.

Brightness or Luminance defines how much light is coming at you. Basically the brighter the display is, the better the colours. For instance, if a display has a low brightness rating the whites can sometimes seem pinkish. With a very bright back light, the whites are comparable to that of a CRT display. The Samsung 570V has a luminance factor of 200cd/m². Most TFT displays range in brightness from around 180cd/m² to 250cd/m².

The dot pitch for this panel is 0.297mm for the horizontal and the vertical. The viewing angles are 60 degrees left, 60 degrees right, 55 degrees up, and 55 degrees down. These ratings are commonly written out like this in the specs; 60/60/55/55 (L/R/U/D). Those numbers mean a person can be at a 60 degree angle to the screen and still be able to view the screen clearly. Laptop displays typically have very shallow viewing angles to prevent people from seeing what you are doing over your shoulder - a sort of privacy screen as it were. About the best set of viewing angles you could ever expect to see would be about 80/80/80/80, the tightest would be around 15/35/45/45 (on a notebook TFT display).

Samsung do not list the response times of the display, so we can't say what they are exactly. Measured in milliseconds, the response time relates to how fast a single pixel can change from one colour to another. The faster the response time, the better. On displays with relatively slow panel response times, text or images can begin to streak if they are moving quickly about the screen real estate. We've saw a bit of this happen on an earlier display. In that instance, what we saw when moving a full page of text up or down quickly was a reddish shadow following the black text as it moved. On the SyncMaster 570V, there is no visible streaking that we could see - which is a good thing as that streaking was distracting.

Resolutions with flat panel displays are a bit different than with their CRT relatives. With LCD displays you always want to operate the display at the maximum resolution - in this case at a resolution of 1024x768 pixels. With the computer set at this resolution there is no dithering effect because the dot in the panel accurately corresponds to the resolution setting. The full list of supported resolutions and frequencies are listed below:

Display Resolutions:
Resolution Freq Hor. Freq Ver. Pixel Clock Standard
640x350 31.5kHz 70Hz 25.2MHz VGA
720x400 31.5kHz 70Hz 28.3MHz VGA
640x480 31.5kHz 60Hz 25.2MHz VGA
640x480 37.5kHz 75Hz 31.5MHz VGA
640x480 35.0kHz 67Hz 30.2MHz MAC
800x600 35.2kHz 56Hz 36.0MHz SVGA
800x600 37.9kHz 60Hz 40.0MHz SVGA
800x600 46.9kHz 75Hz 49.5MHz SVGA
832x624 49.7kHz 75Hz 57.3MHz MAC
1024x768 48.4kHz 60Hz 65.0MHz XGA
1024x768 56.5kHz 70Hz 75.0MHz XGA
1024x768 60.0kHz 75Hz 78.8MHz XGA

The On Screen Display for the 570V TFT is typical of other Samsung displays we have looked at previously (identical in fact). Navigation through the menus are achieved via four of the buttons on the front bezel of the display.
