Frequently Asked Questions - LEM-250A TVLogic

How can I prevent burn-in on the OLED display?

To prevent burn-in or image sticking, turn off the monitor when not in use. Avoid displaying static images, markers, or overlay graphics for more than 10 minutes. Use the Orbiter Circuit (in DISPLAY menu) to shift pixels slightly every 10 minutes. You can also set IMAGE STICK MIN in the SYSTEM menu to automatically dim the screen after a set period of inactivity.

What input signals are supported?

The LEM-250A supports a wide range of signals: SDI (SD, HD, 3G, dual-link), Analog (Composite, S-Video, Component, RGB), DVI (Analog and Digital), and HDMI (with HDCP). It can handle formats from 480i up to 1080p at various frame rates, including PsF and 2K formats.

How do I use the waveform and vectorscope functions?

Press the F4 button (default) or navigate to the WAVEFORM menu. You can select WAVEFORM (luma), VECTOR (chroma), YCbCr or RGB components, and W+V for both. Use WAVEFORM INTENSITY and WAVEFORM TRANS to adjust brightness and transparency. The RANGE ERROR submenu allows you to set min/max luma and chroma levels and blink overexposed areas.

Can I display multiple inputs simultaneously (PBP)?

Yes, the monitor supports Picture-by-Picture (PBP) mode. Press the PBP button on the front panel to cycle through layouts: PBP (two images side by side), 1x1 (single full image selection), and FULL (single input). Use F1 to select which screen to control. You can also adjust border color and thickness in the DISPLAY menu.

How do I set up markers and safety areas?

In the MARKER menu, enable MARKER to choose from various aspect ratio overlays (16:9, 4:3, etc.). Turn on CENTER MARKER and SAFETY AREA (available sizes: 80%, 85%, 88%, 90%, 93%, 100% and EBU presets). Use MARKER MAT to darken the area outside the marker, and adjust color and thickness via MARKER COLOR and MARKER THICKNESS.

How can I calibrate the monitor's color?

Connect a supported color probe (e.g., K-10, i1Pro) to the USB port on the front. In the SYSTEM menu, go to PAGE III, set DEVICE to your probe, then enable COLOR CALIBRATION. Set TARGET LUMINANCE, COLORSPACE, and K-10 CHANNEL. Select CALIBRATION START to begin the process, which takes 20-60 minutes. The probe measures patterns and adjusts internal settings automatically.

What is the function of the GPI (General Purpose Interface) and UMD?

The GPI allows you to assign functions to the 8 pins of the REMOTE connector (RJ-45). Default mapping includes analog channel select, tally indicators, and power on/off. UMD (Under Monitor Display) shows source identification or tally data in a black bar at the bottom. You can customize characters (up to 8), colors, and transparency in the GPI menu. UMD can also be driven via TSL protocol over RS-422.

How do I perform a firmware upgrade?

Save the firmware file to a USB thumb drive. Insert it into the front USB slot. In the SYSTEM menu (PAGE IV), set S/W UPGRADE to ON. The S/W UPGRADE START option becomes available; select it to begin the upgrade. The screen will turn off during the process (20-30 minutes). Do not disconnect power. After completion, the monitor reboots automatically.

How can I adjust the screen brightness and contrast?

Use the front panel CONTRAST and BRIGHT knobs for quick adjustments. For precise control, go to the PICTURE menu where you can set BRIGHT (offset, -100 to 100), CONTRAST (gain, -100 to 100), CHROMA (saturation), PHASE (hue), and APERTURE (sharpness). When using NTSC, you can set NTSC SETUP to 7.5 IRE or 0 IRE.

What are the available scan modes and how do they differ?

Press the SCAN button to cycle through modes: OVER SCAN (96% zoom), ZERO SCAN (no overscan), UNDER SCAN (shows blanking data), 2:1 SCAN (2x zoom, if image is small), 1:1 SCAN (pixel mapping, with pan/zoom using ENTER), FIT WIDTH (stretch to width), and USER ASPECT (custom H/V size). Mode availability depends on the signal type.

Precautions

- Pixel Defects

The OLED panel used in this monitor is manufactured with state-of-the-art technology and has more than two million pixels or more than six million sub-pixels to reproduce the high resolution images. But, some of the pixels in the OLED screen may be stuck to show either always on (red, green, blue) or always off (black or dark). TVLogic guarantees more than 99.999% of the subpixels are operating normally and less than 0.001% of the sub-pixels may be defective. Some subpixels may spontaneously become defective after long period of time, but this is not a malfunction of the monitor.

Burn-In

Similar to CRT or Plasma display, OLED is also a self-luminescence display and due to the characteristics of the materials used for this technology. Burn-In, Image Sticking or regional brightness reduction may occur when displaying a static image, markers, characters, overlay graphics or masked images for specific screen ratio over a certain period of time. To prevent burn-in, it is highly recommended to turn off the power of the monitor when it is not used. And displaying markers, characters, overlay graphics, static images or masked screen for more than 10 minutes are not recommended. Please turn off these functions whenever possible.

2) 16:9 mode : Stretches the image in "1) 4:3 mode" to fit to 16:9 aspect ratio.

3) 4:3Ex : Extends the image vertically without altering the source image. 4) 16:9Ex : Stretches the image in "3) 4:3 mode(extend)" to fit to 16:9 aspect ratio. NTSC and PAL signals are known to be 4:3 aspect ratio signals, but their aspect ratio is not exactly 4:3. Therefore, select "1) 4:3 mode)

to display the exact 4:3 aspect ratio, select "3) 4:3 mode (extend)" to display the image without altering the source image.

1. When input signal is COMPOSITE 1/2/3, S-VIDEO, RGB, DVI ANALOG, DVI DIGITAL or HDMI mode, all "1 - 1),2),3),4)" display the image in 4:3 and 16:9 without altering the source image.

2. For the above aspect modes, ZERO SCAN is the standard scan mode. And, in the other scan modes, aspect ratio changes using the image in its selected scan mode.
