What does “scanlines” mean?

What it means

Scanlines are the visible horizontal banding patterns that simulate the electron beam raster sweep of vintage Cathode Ray Tube (CRT) monitors. In the video game collecting niche, they refer to the visual effect, either inherent to the original hardware's output or deliberately added by modern emulation or display filters. This is not a defect on the game media itself, but rather an artifact of the display technology used to view the game. For collectors, the presence of authentic scanlines confirms the viewing experience matches the original hardware intent, distinguishing it from a clean, modern digital presentation.

What it does to price

The presence of authentic, hardware-level scanlines (i.e., viewing on a proper CRT or an unmodified original console output) generally adds a minor premium, typically in the 5-15% range, when compared to a pristine digital screenshot or a modern HDMI capture that smooths the image. If a game is being sold as "original hardware condition," the ability to demonstrate the authentic scanline effect justifies a slightly higher price ceiling. Conversely, if a seller claims scanlines are present but the media is visibly damaged (e.g., screen burn-in on the cartridge), the damage outweighs the aesthetic value, leading to a price reduction of 10-25%.

How to spot it

Authentic scanlines are tied to the display, not the cartridge or disc. To verify the effect, sellers must provide video evidence of the game running on the actual intended hardware, not just static photos. Common mistakes involve sellers applying a "scanline overlay" filter in photo editing software; these overlays look too uniform or sharp compared to the subtle, slightly imperfect lines of genuine CRT output. Look for slight color bleeding or phosphor glow artifacts in high-resolution photos; these are indicators of true vintage display characteristics.

Buying smart

Paying a premium for scanlines is worthwhile when the buyer specifically seeks the authentic, period-accurate visual experience, often for display purposes or deep emulation enthusiasts. This premium is unwarranted if the buyer is primarily concerned with high-definition clarity or portability, as modern upscaling often renders the scanline effect moot. A fair deal involves the seller clearly stating the viewing method (e.g., "Viewed on original CRT") and the asking price reflecting the slight aesthetic niche appeal, not a major functional difference.

Selling smart

Listing the item with a clear reference to the authentic visual style drives buyer interest among dedicated retro enthusiasts. The most effective listing tactic is including a short video clip showing the game running on the original hardware, clearly displaying the scanlines. A simple descriptor like "Authentic CRT Output Visuals" earns the premium. If the listing only shows static photos, the seller forfeits the value associated with the hardware's specific visual output, forcing the buyer to assume a standard digital presentation.
