The film-theatrical ruler from the largest manufacturer LCD-matric for projectors has replenished with model Epson EMP-TW700. We also bring its review to your attention. The stylish case of graceful contours has got to this projector from only in slightly modified kind. The large strongly acting objective rushes to eyes. The case, except for a silvery plastic insert in front, is made of plastic with milky-white smooth (but not glossy) a covering. The case rather nonspottable, prints of fingers and a dust on it are not allocated. On the top panel is closer to a back part buttons of management and indicators of a condition are located. Besides on the back panel the socket and the mechanical switch of a feed, a socket for lock Kensingtona and round window IK-priemnika are placed. The second IK-priemnik in a forward part. Vozduhozabornaya the lattice is located on the bottom, fulfilled air through a lattice on the forward panel is blown. The projector is equipped by two legs unscrewed from the case, allowing to eliminate a small skew and-or to raise a forward part of a projector at its accommodation on a horizontal surface a little. For fastening to an arm in the 1750 notebook satellite toshiba bottom of a projector metal plugs with a groove are fixed. Matovo-bely'y the board large enough and weighty, it all such okrugly'y, and, despite of narrowing in the central part, little bit thickish. Nevertheless, the majority of buttons to press conveniently and as it is not enough buttons, they are located freely, distributed on groups, and not all identical, that the necessary buttons easily are to the touch. There is the light-emitting diode illumination, joining the phosphorescing button. Functions of inclusion and deenergizing are prodigally carried on different buttons. About pressing the button the winking red light-emitting diode signals. On fresh batareykah and in a small premise of a command of the board reach a projector at any mutual orientation of the board and a projector result of work of two looking hardly in parties Ik-diodov of the board, two IK-priemnikov a projector, multiplied on reflections IK-luchey from subjects and walls. from sockets 1750 notebook satellite toshiba standard, for connection to them of sources of video signal of any specific cables it is not required. Unusual to home appliances socket D (or it is simple D) is offered to be used for connection to sources RGBS-signala, equipped socket SCART. At the complete set of delivery there is an adapter from socket SCART on D-vilku and on RCA-shteker which is connected to a composit input of a projector and serves for input sinhrosignala. Basically, input D is compatible and with componental cvetoraznostny'mi signals. Using D for SCART-podklyucheniya, it is necessary in the menu for D-vhoda to choose a corresponding operating mode. Switching between sources is carried out or search of all by means of button Source on the case of a projector, or 6-th buttons on the board in group Source everyone corresponds to one video input. Autorecognition of active connection is not present. The screen with an electromechanical drive can be connected to output Trigger out at the included projector on it moves In (if 1750 notebook satellite toshiba this function is not disconnected). The design of the menu ascetic is not present any cvetasty'h ikonok, animation transitions and other ukrashatel'stv. A font of the menu legible, but the menu as a whole a little melkovato, that reduces its ergonomics. It is a lot of adjustments, all of them are not located on pages of the first level are born, not always opravdanno, on pages of the fourth level of an investment. To move under the menu it is convenient, the help with current functions of buttons (it can be disconnected) is below deduced. At adjustment of the parameters influencing the image, for the screen the minimum of the information only the list of modes or toddlers that facilitates adjustment of a picture is deduced. For operative adjustment of the image it is 1750 notebook satellite toshiba possible to take advantage to the one-line menus containing a number of the important parameters. This menu knopami Select on the case and on the board is caused, and parameters get over arrows vverh-vniz. The menu is not Russified. Focusing of the image on the screen is carried out by rotation external obodka with a notch, and change of a focal length of a wide ring of an objective. Two ridge kolesika near to an objective allow to shift an objective vpravo-vlevo and vverh-vniz so, that the image thus moves a maximum on 1 % from height upwards and downwards on a vertical and on % from width to the right and to the left across concerning the central position. At shift across the range of vertical shift decreases and on the contrary. The central position of an objective is noted easy, with click, fixing kolesikov. There is a function of digital correction vertical trapeceidal'ny'h distortions (+/- degrees). Adjustment of a projection can be facilitated, having displayed a test pattern button Pattern of the board. Modes of geometrical transformation 6: Normal the image without distortions increases for all screen, is optimum for viewing films in 1750 notebook satellite toshiba a format 4:3, Squeeze the picture increases and stretched up to a parity 16:9, it is ideal for anamorfirovanny'h films, Zoom increase till width of the screen, the variant of viewing of a picture 4: on the wide screen approaches for format LetterBox, Wide increase and non-uniform extension across so, that in the center of distortions is less. And modes without increase: Squeeze Trough with a stretching, and Trough the pixel of a matrix corresponds to pixel of an initial picture. In mode Auto the projector tries to define itself an optimum mode of transformation, choosing from Normal, Squeeze and Zoom. Only in mode Zoom there is an opportunity hardly to draw in the image on a vertical and to move it vverh-vniz so that on the screen subtitles were located. Adjustment Output Scaling influences on a scrap of edges of the image, at value Normal the picture increases a little and on perimeter leaves for area of a projection, at Larger nothing obrezaetsya a little. Functions stop-kadra and are not present scaling, the conclusion of the image temporarily stops button Blank. In the menu the type of 1750 notebook satellite toshiba a projection (face-to-face / on a gleam, usual / potolochnoe fastening) gets out. The projector srednefokusny'y, and at the maximal focal length of an objective so in general dlinnofokusny'y, therefore at its face-to-face displaying is better to have approximately on a line of the first of some spectators or for it. On a picture very big influence renders a current color mode, therefore to begin adjustment of the image better with a choice of a mode. The mode defines capacity of a lamp, a structure of color correction, and also vklyuchenie-vy'klyuchenie firm Epson Cinema Filter. In mode Dynamic and Living Room the filter is disconnected, in others is included, in modes Theatre Black and capacity of a lamp (and noise from system of ventilation) decreases. In a management the illustrated recommendations on use of modes in various conditions of viewing are resulted. It is a pity only, that the user cannot directly operate the correcting filter and capacity of a lamp. The adjustments influencing on yarksotny'y and color balance many. In some cases for achievement of the same purposes it is possible to take advantage of alternative ways. So yarkostny'y balance it is roughly possible to arrange habitual 1750 notebook satellite toshiba brightness (Brightness) both contrast (Contrast) and adjustments a level white (White Level) and a level black (Black Level). For thin fine tuning yarkostnogo balance it is necessary to pass to page Gamma where it is possible to choose the preestablished values or most to correct a curve gamma-korrekcii. Thus the corrected level of brightness can be chosen as on stylized gamma-krivoy, and it is direct on the current image, having taken advantage kursorom-ukazatelem. The color balance is adjusted intuitivno-ponyatny'mi a saturation (Color Saturation), a shade (Tint), color temperature (Abs. Color Temp., from 50 up to 10000) and a shade of a leather (Skin tone). The advanced users can adjust brightness and contrast of three colors (RGB) or a shade (Hue) and a saturation (Saturation) six (RGBCMY). In case of when the most light parts of the image peresvecheny', inclusion of firm mode EPSON Super White can help. Function Auto Iris automatically adjusts a diaphragm covers, when the image basically dark, and opens when light. Modes of adjustment of planimetric sharpness two: Standard a traditional toddler, and Advanced the whole toddlers defining, what contours, in what direction and how much to allocate. (Depending on a current mode and type of connection some 1750 notebook satellite toshiba adjustments can be inaccessible.) For orientation near to each filled cell the name of the mode which has served by a starting point is deduced. In addition adjustments of the image and modes of transformation are automatically kept for each type of connection and-or a kind of video signal, and-or a mode. There is a function of automatic inclusion at submission of energy (Direct Power On, it it is possible to switch on and off), the timer on deenergizing at absence of a signal (Sleep Mode, it it is possible to switch off or choose an interval of operation from 5, and mines), protection against casual inclusion a projector will join only after second pressing button Power the case (Child Lock), blocking of all buttons on the case (Operation Lock), and the prompt can be changed for the grasped picture (User's Logo). The projector, most likely, can be operated on interface RS-232C (if it is not intended only for updating an insertion), but in a management except for raspayki the socket is not present any other information concerning this interface. For correct comparison of the given projector with others, having the fixed position of an objective, measurement were spent at shift of an objective 1750 notebook satellite toshiba upwards hardly more than on % (the bottom of the image was a little above an axis of an objective). Results of measurements by technique ANSI for Epson EMP-TW700: The maximal light stream practically corresponds to passport value. We shall notice, that only in mode Dynamic of adjustment stole up so, that brightness would be maximal. In particular we have established Abs. Color Temp. = 65 K and Skin tone = 4. Non-uniformity of light exposure is enough greater, but visually it almost imperceptibly is simple in below in the center the screen a little svetlee, and to edges and above darkens, sharp differences are not present. However, the manufacturer warns, that uniformity and a light stream reach the best values at the central position of an objective. Contrast very high. Attention! The resulted values of a level of sound pressure from system of cooling are received on and they cannot be compared to nameplate data of a projector directly. The lowered brightness (Theatre black and 2) Projector silent, especially in modes Theatre black and 2. Unfortunately, to the user the option is not left if it would be desirable to achieve 1750 notebook satellite toshiba the maximal silence, necessary to be reconciled with very low brightness as in mode Dynamic with the minimal correction of color and without the light filter it is impossible to include low capacity of a lamp compulsorily. Noise from system of ventilation does not irritate. Testing VGA-podklyucheniya was spent at the sanction 12 on 7 pixels (vertical frequency of Hz). White and black weeding are subjectively perceived as very uniform. On a subfloor of patches of light is not present. Geometry ideal. Details differ both in shadows, and in svetah (after small fine tuning White Level and Black Level). The scale grey in regular intervals grey, its small color shade is defined by the chosen color temperature. Colors bright and correct. Clearness very high. Chromatic aberrations of an objective are minimal only in the top corners it is possible to notice thin (less than 1/ pixels) svetlo-fioletovuyu kaymu on borders of contrast objects. On usual images autofine tuning under parameters VGA-signala works unsatisfactorily. 1750 notebook satellite toshiba The parameters found by automatics are remembered, and compulsory start of autofine tuning is not present, therefore a unique variant to receive a precise picture it to adjust parameters manually. The mode 12 on 7 pixels at connection to DVI-vy'hodu (by means of kabelya-perehodnika with HDMI on DVI) videocards of a computer is supported (the projector informs, that is ready to accept a signal up to 19 on 10 pixels). For correct display without interpolation it is necessary to establish Output Scaling = Larger. HDMI-podklyuchenie it was tested in modes 480p, 576p 720p and 1080i at connection to DVD-pleeru. YArkostnaya and color clearness surpass parameters of a source more than 5 and 2 TVL accordingly. Both at DVI-, and at HDMI-podklyuchenii for display of all range of brightness of shades it is necessary to expose DVI-Video Level in Expanded. As a whole, digital connection, in comparison with componental analog, is characterized, first 1750 notebook satellite toshiba of all, by high microcontrast. YArkostnaya clearness very high. Color clearness at composit and S-Video-podklyucheniyah could be and above. Test patterns with gradients of colors and with a scale grey have not revealed any artefacts of the image. Weak gradation of shades in shadows and on light sites of the image well differ (insignificant blockages in light and dark areas do not leave for safe borders). Color balance correct. Parameter Progressive defines an operating mode of function deinterleysinga: Off the image is deduced on fields, Video for motionless parts of the image (i.e. conterminous for two staff) is carried out fair deinterleysing, and varying are deduced on fields, Film the projector tries to restore completely initial the staff. Quality deinterleysinga depends on type of a signal, for PAL in modes Video and Film on the frequent motionless worlds it is possible to notice set of artefacts which are absent at NTSC-signale. In any case, the projector is not capable to execute correctly transformation 2-2, i.e. easier to stick together the staff from two adjacent fields, nevertheless, 1750 notebook satellite toshiba with transformation 3- projector consults, correctly restoring staff in a second from NTSC-signala. Smoothing of borders of objects is not made diagonals on objects in movement have expressed a step. It is possible to approve, that Epson EMP-TW7 it is slightly modernized. TW7 has received new optical system, with very good objective and little bit increased range of a focal length (due to its long part, unfortunately), well and works a little bit more silently, than TW600. It has not affected at all the list of merits and demerits it has remained practically without changes. Completely the potential opens a projector at connection to a source with qualitative progressive development (better on HDMI) as the algorithm built in a projector deinterleysinga not always works ideally. It is impossible to operate directly capacity of a lamp, a diaphragm and inclusion of the optical filter Other discussions in conference:
