Maintenance  
Screen Cleaning  
Periodically clean the screen surface using ammonia-free cleaning wipes (Marshall Part No. V-HWP-K). A clean micro-  
fiber cloth can also be used using only non-abrasive and ammonia-free cleaning agents. Do not use paper towels.  
Paper towel fibers are coarse and may scratch the surface of the polycarbonate faceplate or leave streaks on the  
surface. Antistatic and fingerprint resistant cleaning agents are recommended. Do not apply excessive pressure to the  
screen to avoid damaging the LCD.  
Faceplate Dusting  
Dust the unit with a soft, damp cloth or chamois. Dry or abrasive cloths may cause electrostatic charge on the surface,  
attracting dust particles. Neutralize static electricity effects by using the recommended cleaning and polishing practice.

As the V-R261P-AFHD monitor has a native resolution of 1366 x 768 RGB pixels, incoming images are automatically  
scaled to fit the screen:  
Inspect the unit for any physical damage that may have occurred during shipping. Should there be any damage,  
immediately contact Marshall Electronics at (800) 800-6608. If you are not located within the continental United States,  
call +1 (310) 333-0606.  
In 16:9 mode, images are scaled up or down to fill the entire 16:9 screen (1366 x 768).  
In 4:3 mode, images are scaled to fill the maximum 4:3 portion of the screen (1024 x 768), with black bars filling  
the remainder of the screen.  
Installation  
The V-R261P-AFHD monitor provides a VESA standard 200 mm x 100 mm hole pattern for attachment to VESA  
mounts supporting at least 15 lbs. An adapter plate is also included, providing both 75mm and 100mm standard hole  
patterns.  
4:3 Mode  
16:9 Mode  
The V-R261P-AFHD can be configured as a desktop monitor with an optional stand (Marshall Part No. VP-LCD171H-  
ST-01).

Scanning Modes  
Connections and Power-On  
Use this setting to switch between normal and underscan modes:  
Plug the V-PS24-7.5 power supply into an AC power source (100-240 V @ 50/60 Hz). Attach the 4-pin XLR connector  
to the back of the monitor. Please note that 24VDC can be also supplied directly to the monitor from a variety of  
sources. The monitor will draw approximately 4.2 Amps at 24 Volts in operation.  
In normal scan mode, the active portion of the video signal is displayed on the screen, with 0% overscan.  
In underscan mode, area around the active video area is displayed on the screen, resulting in blanking intervals  
being shown around the perimeter of the active image. Use this mode to clearly view the edges of the active video  
area.  
Connect the required cables for video signal input and output. (Power must be applied to the V-R261P-AFHD for the  
active loop-though outputs to be activated.) All BNC connectors are rated at 75Ω.  
Turn on the unit by pressing the power button located on the front panel. Select a video input by pressing the  
corresponding input select button.  
Delay Modes  
Use this setting to enable one of three delay modes (H/V, H, V):  
In H/V delay mode, both horizontal sync and vertical sync are delayed, resulting in both horizontal and vertical  
blanking periods being shown on the screen.  
In V delay mode, vertical sync is delayed so that the vertical blanking period is displayed on screen.  
In H delay mode, horizontal sync is delayed so that the horizontal blanking period is displayed on the screen.  
Note: Delay modes are only available in normal scan mode.
