H. Size Adjusts the horizontal size of the screen.

(Analog input only) If the “AUTO Adjust function” do not give you a satisfactory picture setting, a further

tuning can be performed using the “H.Size (V.Size)” function (dot clock). For this a Moiré

test pattern could be used. This function may alter the width of the picture. Use left/Right

Menu to center the image on the screen. If the H.Size (V.Size) is wrongly calibrated, the

result would look like on the left drawing. The image should be homogeneous.

Fine Improve focus, clarity and image stability by increasing or decreasing this setting.

(Analog input only) If the “Auto Adjust function” and the “H.Size” function do not give you a satisfactory

picture setting, a fine tuning can be performed using the “Fine” function. For this a Moiré

test pattern could be used. If the Fine value is wrongly calibrated, the result would look

like on the left drawing. The image should be homogeneous.

Auto Fine This function automatically and periodically adjusts the “FINE” setting for change in signal

(Analog input only) condition. This function adjusts approximately every 33 minutes.

H. Resolution Adjusts the horizontal size by increasing or decreasing the setting.

Press “Right” button to expand the width of the image on the screen.

Press “Left” button to narrow the width of the image on the screen.

V. Resolution Adjusts the vertical size by increasing or decreasing the setting.

Press “Right” button to expand the height of the image on the screen.

Press “Left” button to narrow the height of the image on the screen.

Expansion Sets the zoom method.

FULL: The image is expanded to the MDview model’s native mode, regardless of the

resolution.

ASPECT: The image is expanded without changing the aspect ratio.

OFF: The image is not expanded.

CUSTOM: When CUSTOM is selected as the Expansion mode, it becomes possible to

adjust the H. ZOOM., V. ZOOM, and ZOOM POS.

H.ZOOM The image is expanded from 1 to 3 times in the horizontal (H. EXPANSION) direction by

(Available in Custom 0.01 increments.

Expansion mode only)

V.ZOOM The image is expanded from 1 to 3 times in the vertical (V. EXPANSION) direction by

(Available in Custom 0.01 increments.

Expansion mode only)

ZOOM POS. Sets the point from which the screen will be expanded when either H.ZOOM or V.ZOOM is

(Available in Custom selected as the expansion method. Options are CENTER and LEFT TOP.

Expansion mode only) CENTER: H.ZOOM expands the image from the centre outward to the sides of the screen.

V.ZOOM expands the image from the centre towards the top and bottom of the screen.

LEFT TOP: Indicates the set point for image expansion (TOP in V. Zoom, LEFT in

H.ZOOM). If the resolution does not fill out the screen, when expanding, the image will not

expand past the TOP or the LEFT of the screen. The image can be expanded past the

right and bottom edges of the screen.

Tag5 Gamma Selection Allows you to manually select the brightness level of grayscale. There are five selections:

NO CORRECTION, 2.2, OPTION, PROGRAMMABLE and CUSTOM.

NO CORRECTION: No Correction possible.

2.2: The value is fixed at 2.2.

OPTION: There are two ways of OPTION selection.

1: This setting is recommended for Video sources. Gray areas look much brighter than

with the NO CORRECTION setting.

2: A factory preset DICOM like gamma correction is enabled. This option provides an

essential improvement for viewing DICOM compliant medical images. However, this

option does not substitute a true DICOM Part 14 GSDF curve.

PROGRAMMABLE: The programmable Look-up tables in the display are used. NEC

GammaCompMD software provides calibration to a true DICOM Part 14 GSDF curve.

CUSTOM: Below items can be adjusted when CUSTOM is selected as the GAMMA

SELECTION setting.

Custom Value: The gamma value is selected from the rate of 0.5 to 4.0 by 0.1 steps.

When the COLOR CONTROL is sRGB, the value is fixed at 2.2 and NOT ADJUSTABLE.

Offset: The OFFSET digitally adjusts the black level after the signal is converted from

analog to digital.
