Lenovo Oem Logo Bmp 120x120 High Quality Review
Even with the correct file, issues arise. Here are solutions based on crowdsourced data from IT teams:
| Problem | Likely Cause | Solution |
| :--- | :--- | :--- |
| "Invalid logo file" | Wrong dimensions or compression | Verify 120x120, 24-bit, no RLE. |
| Logo appears squashed | Aspect ratio mismatch. | Center the logo on a 120x120 transparent canvas. Do not fill canvas. |
| Colors are inverted (blue=orange) | BMP saved with top-down vs. bottom-up row order. | Use Photoshop; ensure "Flip row order" is correct. Or use ImageMagick: mogrify -flip |
| Logo shows, but low quality | Used MS Paint or JPEG conversion. | Recreate using vector source and "Nearest Neighbor" resampling. |
| Flashing works, but logo never appears | Fast Boot or Full Screen Logo disabled in BIOS. | Enter BIOS Setup (F1 on boot). Enable "Display Full Screen Logo." | lenovo oem logo bmp 120x120 high quality
First, let's address the core technical limitation. Unlike consumer motherboards from ASUS or MSI that accept high-resolution JPEGs, Lenovo’s UEFI BIOS (especially on ThinkCentre, ThinkStation, and older ThinkPad models) adheres to a strict legacy standard: EPA (Energy Star) logo compliance. Even with the correct file, issues arise
Historically, the EPA logo displayed during boot was a 1-bit or 4-bit bitmap. Lenovo maintained this standard for custom boot logos. Through reverse engineering and official BIOS documentation, the accepted parameters are: If you try to upload a JPEG, PNG,
If you try to upload a JPEG, PNG, or a BMP that is 300x300, the Lenovo BIOS Flash utility (usually WinFlash64.exe or the BIOS Setup utility) will reject it with a vague error: "Invalid Logo Image."
| Problem | Likely Cause | Solution |
|---------|--------------|----------|
| Pixelated or blocky | Source was low-res or compressed | Redraw vector at 120x120 |
| Colors washed out | BIOS forces 16-bit color fallback | Ensure 24-bit BMP, not 32-bit with alpha |
| Logo not showing | Wrong resolution | Verify exactly 120x120 |
| White lines / noise | BMP header uses invalid DPI fields | Use tool like bmps2bootlogo to clean header |
