Set up an old CRT monitor for retro gaming and was struck by how different the visual experience is compared to modern LCD displays.
The phosphor glow creates a warmth and depth that digital displays struggle to replicate. Colors blend naturally at pixel boundaries, creating smooth gradients that LCD pixels render with sharp edges.
Response time is effectively zero – no motion blur or ghosting that affects fast-moving graphics on LCD panels. The electron beam draws each frame instantly, making old games feel incredibly responsive.
The curved screen geometry creates interesting visual characteristics. Slight pincushion distortion and brightness variations across the screen surface add character that perfectly flat displays lack.
Scan lines and dot pitch create texture that many retro games were designed around. Pixel art that looks harsh on modern displays gains softness and atmosphere when viewed as originally intended.
The analog nature means infinite resolution within the bandwidth limits of video signals. Text and graphics scale smoothly rather than being constrained to fixed pixel grids.
But the drawbacks are significant too. The bulk, weight, and power consumption are enormous compared to modern displays. Heat generation and electromagnetic fields create environmental concerns.
High refresh rates were standard on CRT monitors when LCD panels were limited to 60Hz. Gaming enthusiasts maintained CRT displays for competitive advantages long after LCD technology improved.
Color calibration and geometry adjustment require analog controls with complex interactions. Getting perfect image quality requires patience and understanding of analog circuit behavior.
The distinct visual characteristics influenced artistic choices in older games and software. Developers worked with CRT limitations and characteristics rather than fighting against them.
Modern CRT emulation attempts to recreate these visual characteristics in software, but capturing the analog subtleties in digital form remains challenging.
