[Nishikawa Kazuhisa's irregular column] Nippon Samsung "S27A850D" ~ 27 -inch PLS panel 2,560 x 1,440 dots LCD display -PC Watch

　On January 10, Samsung Nippon announced that the 2012 model will renew the lineup of LCD displays and ship 20 models from January 19.This time, I would like to introduce the "S27A850D" equipped with a 27 -inch PLS panel.

　This is the first time I tried the real machine, although I knew the PLS (Plane to LINE Switching) LCD panel.I'm curious how it is different from IPS.According to the table of the "LCD panel feature comparison" listed on the website, the biggest difference is "permeability", and the PLS type is said to be higher than the IPS type.Karakuri wants to see the page, but the higher the transparency, the more bright, so if the same brightness is the power saving than the IPS type.

　There are two PLS recruitment products announced on January 10, 27 -inch "S27A850D" and 24 -inch "S24A850DW".The outline is that the former is 27 type/2,560 x 1,440 dot/DVI-D x 2, DisplayPort/69,800 yen, the latter is 24 type/1,920 x 1,200 dots/DVI-D, mini D-sub15 pin, DisplayPort/39,800 yenIt will be before and after.Although the input configuration is partially different, the difference is 30,000 yen depending on the type 3+resolution.This time, the editorial department received the 27 -inch "S27A850D".The main specifications are as follows.

　The screen size is 27.As I wrote at the beginning, it is a PLS LCD panel.It is non -glossy with LED backlight.The maximum resolution is 2,560 x 1,440 dots, the largest general display connecting to a PC.

　The color gamut is 100%compared to SRGB.The viewing angle is 178 degrees up and down/left and right, the response speed in the middle color is 5 ms, the brightness is 300 cd/square m, and the contrast ratio is 1,000: 1 (dynamic contrast ratio 5 million: 1).This class can be a standard performance.

　The input terminal is dual link DVI-D × 2, DisplayPort × 1, USB 3.0 × 3, USB uplink x 1, line input, headphone output, power input.3 -port USB 3.The point is that the built -in HUB is high.The speaker is not built -in.It also supports PBP (Picture by Picture), which displays two inputs on one screen.

　The maximum power consumption is 69W (53W without USB).According to the company's explanation, the power consumption is 30%lower under the same brightness conditions.For reference, the EIZO "CG245W" owned is up to 100W, the Apple "Thunderbolt Display" is up to 250W (Thunderbolt Display, which is charging MacBook Pro), and the HP "ZR2740W" is up to 120W (factory initial setting 95W).The power consumption is considerably reduced from the same size and resolution ZR2740W.

　In addition, the "Eco Motion Sensor" and "Ecolite Sensor" functions can easily set back light from the menu in three stages (50/75/100%) from the time of normal use, and "Magic ECO function.(Eco Saving) is equipped with a function that supports energy saving more easily.

　The height is up to 150 mm, 2 degrees before tilt to 25 degrees, swivel 270 degrees, and pivot.The size is 642.5x442.5x224.It is 5mm (width x depth x height), but it contains a stand, and the thinnest part of the liquid crystal panel (border side) is quite thin at about 2 cm.Weight is 6.6kg (including stand), without a stand 4.It will be 5kg.

　In the viewing angle, the photos of the door are quite angry both up, down, left and right, but it can be seen that there is almost no change in color and contrast than the front photo.It can be said that it is almost the same as the IPS type.The coloring is accurate, the standard setting is a little flashy, but it is sharp and the contrast is high.It's more than enough for a general display.

　The design is a calm atmosphere in a glossy black only on the border side, and the others are matte black.I just think the pedestal is a little big.The weight is 6 including the stand.Because it is 6kg, it does not bother a little movement or positioning.

　Adjustment of height, tilt, swivel and pivot is not too heavy and not too light.It moves smoothly and stops.It is stable without rattling and it is a good impression.

　Cable management is simple as you can see from the photos.It may be a bit cramped if you put all the AC cables, DVI cables, DisplayPort cables, and four USB cables, but there is no problem in normal use.

　What is interesting is the AC adapter.When it was taken out of the package, the cable from the AC adapter was strangely short (about 50cm), and the position of the power switch and the AC inlet (there is a Mickey type connector on the back of the power switch) is not normal.It was a dent that could store the AC adapter at the top of the back, and it was a crisp.

　This is my first time, though I have tried various displays for many years.It is unknown whether it emphasized the thinness of the specifications or that it could be easily replaced even if the power supply was broken, but it is a reasonable implementation.

　OSD is quite abundant, including ECO -related mode settings.To briefly explain only a little difficult part, "Magic Bright" optimizes image quality according to the environment, and "Magic Color" achieves vivid natural colors without reducing image quality with the image quality improvement technology developed by the company.do.

　The contents are as follows.

　Video → Magic Bright (user adjustment/standard/game/cinema/dynamic contrast).Video → Magic Color (off/demo/full/intelligent).Full is image quality improvement with skin color, demonstration is a comparison screen with normal mode, and intelligent improves image quality other than skin color.Video → brightness/contrast/sharpness/reaction time (standard/high speed/highest speed).

　Color tone → red/green/blue/color temperature (blue system 1/blue system 2/standard/red system 1/red system 2/user setting)/gamma (mode 1/mode 2/mode 3).

　Size and position → PBP (Picture by Picture) → Mode (on/off)/Contrast.At this time, the left side is 1 digital or DisplayPort, and the right side is digital 2.The resolution is 1,280 x 1,440 dots or 1,280 x 1,024 dots.

　Size and position → Image size (automatic/wide/4: 3/screen)/H-position/V-position.

　Size and position → ECO → ecomotion sensor (off/5 minutes/10 minutes/20 minutes/30 minutes/1 hour)/backlight (off/dark)/eco light sensor (off/on)/sensitivity (high/medium)/Low)/Brightness level (bright/maintained/dark)/Eco -saving/Eco -icon display (off/on).

　Size and position → Menu transparency (off/on)/Language/PC/AV mode (PC/AV) Image size expand/automatic source detection (automatic/manual)/display time (5 seconds/10 seconds/20 seconds/200/200/200Second) Time/Repeated number (fast/1 second/2 seconds/repetition) Response speed/customization key (ECO/MAGIC/image size)/off timer on/off(Off/on)/off -timer setting (1-23 hours)/Reset.

　The consumers are all included, and although there is no particular dissatisfaction, the color tone is that the expression is ambiguous and you want to change the notation a little."Standard/Gamma 1" is SRGB (6500k/2).It seems to be 2), but there is no specific value for the color temperature or gamma, and I am worried that it is really there.

　The included driver CD contains a display driver, manual, and setup program, including ICM profile, "MagicRotation Auto".MagicRotation Auto is a mechanism that detects the rotation of the display with a sensor and automatically rotates the Windows screen.

　"SMS27A850" for reference.It is a chart listed with SRGB compared to SRGB in the ColorSync utility of Mac OS X (SRGB is the light part of the back side, SMS27A850 is the dark part of the table..ICM).

　As described above, the S27A850D has two DVI-D and one DisplayPort, and the use of a PLS panel is attractive to save energy while taking over the size of the IPS viewing angle.USB 3.The point is that the built -in HUB is also high.

　Although the LCD display that has recently adopted the IPS panel has become relatively inexpensive, this content is reasonably reasonable.It is one that can be a candidate for users looking for a high -end 27 -inch LCD display.
