Question 1

Can this monitor be used with old DOS resolutions (320x200, etc.)?

Accepted Answer

No, the LCD2190UXP monitor does not support true classic DOS resolutions like 320x200 or 640x350. This monitor has a native resolution of 1600 x 1200, which is well beyond DOS standards.

However, it has an EXPANSION function with several modes:

FULL - Enlarges the image to 1600 x 1200 regardless of the input resolution
ASPECT - Enlarges without distorting proportions
OFF - No enlargement
CUSTOM - Independent adjustment of horizontal and vertical zoom (1x to 3x)

The lowest supported resolutions remain 640 x 480 (60-85 Hz) and 720 x 400 (70-85 Hz). To display a true DOS resolution, the monitor would first need to interpolate it before enlarging. On an LCD screen, text may appear different compared to an old CRT screen, as enlarged pixel interpolation does not exactly reproduce the original sharpness.

Summary: Limited display capability for old DOS applications. If this is your primary need, a vintage CRT screen would be more appropriate.

Question 4

Why does the red light blink when I press the power button?

Accepted Answer

A blinking red light on the NEC E556 monitor indicates that the device has detected a problem and has entered automatic protection mode to prevent damage to internal components.

Main causes:

No video signal detected - The monitor is not receiving any video input from the source equipment (computer, media player, signaling system)
Internal overheating - Thermal protection has been activated (blocked ventilation or ambient temperature too high)
Internal power issue - Malfunction of the power supply unit or an internal component
Startup fault detected - Internal self-test revealing a hardware issue

What to do:

Turn off the monitor and wait 30 seconds
Check that all cables (power and video) are properly connected
Turn the monitor back on
If the red light blinks again, try another video input or another video cable
Ensure that the fan is not obstructed and that the device has adequate ventilation around it
If the problem persists after these checks, the monitor requires professional repair

Refer to the technical manual for your model for specific LED codes and advanced diagnostic procedures.

Question 5

The locking mechanism of the base of my MultiSync 1940CX monitor is broken, with a screw stuck inside. How can I fix it?

Accepted Answer

The base fastening mechanism of your NEC MultiSync 1940CX uses locking tabs that align with holes at the back of the stand and are held in place by a screw. Your tab has fractured, which is a serious physical damage affecting the stability of the monitor.

Immediate Steps

Remove the stuck screw: Use an appropriate screwdriver (probably M4) and apply slight downward pressure while turning slowly to avoid further tearing the plastic. Be patient - forcing it could worsen the damage.
Extract the fragments: Carefully remove all plastic pieces from the locking mechanism and the support base. Ensure that nothing is blocking the threading.

Repair Solutions

Replace the original stand: Contact NEC support mentioning the 1940CX model and request a replacement part for the base stand. This is the best solution to restore factory stability.
Use VESA mounting: According to the technical specifications of the 1940CX, this monitor supports VESA mounting 100x100 mm with screws of depth 2.0-3.2 mm. You can use an articulated arm or a VESA wall mount instead of the provided stand. Remember to first remove the 4 mounting screws and the metal plate from the factory stand.
Professional repair: A screen repair shop can replace the entire stand if NEC spare parts are not available.

Important Warning: The locking mechanism is essential for the stability of the monitor. Do not use the broken stand - the risk of the screen falling is real. The VESA solution is safe and recommended while waiting for a stand replacement.

Question 7

How to use the built-in speakers of the NEC MultiSync LCD2170NX monitor?

Accepted Answer

The NEC MultiSync LCD2170NX monitor is equipped with built-in speakers that allow you to play sound from your computer directly without the need for additional external audio equipment.

Connecting the speakers to your computer: The first step is to establish a separate audio connection between your computer and the monitor. Plug an audio cable (standard 3.5 mm audio jack) into the audio output of your computer. This output is usually found on the sound card of your PC or on your Mac, and is marked with a speaker symbol. The other end of the cable should be connected to the audio input of the monitor, located on the back panel of the device. It is important to note that video cables (VGA or DVI) alone are not sufficient to obtain sound - the audio cable must be plugged in separately.

Turning on the monitor and checking the connection: Make sure the LCD2170NX monitor is powered on and that the power indicator (located on the front panel) is lit. You can also check that the audio cable is not damaged and is securely plugged into both connectors.

Adjusting the volume via the OSD menu: Use the control buttons located on the front panel of the monitor to access the OSD (On-Screen Display) menu. Press the SELECT or MENU button to open the interface. Navigate to the Audio or Volume section using the arrow buttons. You can then increase or decrease the sound level according to your preferences. The menu will display the volume level in real-time as a progress bar.

Checking your computer's audio settings: If you hear no sound despite the proper connection of the cables and checking the monitor's volume, check your system's audio settings. On Windows, go to Audio Settings and ensure that the monitor is set as the default audio output device. On Mac, check System Preferences > Sound to confirm that the audio output is directed to the monitor.

Testing the sound: Play an audio file, video, or multimedia application on your computer to check that sound is correctly emitted through the built-in speakers of the monitor. You should hear sound coming from the speakers located at the base of the monitor.

If you still do not have sound after checking all these elements, ensure that the audio connector of your computer is not faulty, and consider using a higher quality audio cable or checking the audio drivers of your sound card.
