Digital TV almost always wins when it comes to resolution.
Analog TV
Bottom line: Analog TV never matched the resolution potential of digital. At best, analog gave you a softer SD image; digital enables HD, Full HD, and 4K.

Analog TV
- Standard resolution only: Traditional analog formats like NTSC (in North America) and PAL/SECAM (in Europe/Latin America) topped out at what we’d now call “standard definition” (roughly 480i for NTSC, 576i for PAL).
- No fixed pixel grid: It was a continuous signal, so in theory you could get good sharpness if the broadcast chain and the TV set were top quality. But in practice, noise, ghosting, and interference reduced clarity.
- Quality varies: The picture could degrade gradually with weak signal strength, showing snow or ghosting rather than cutting out completely.
- Much higher resolutions possible: Even the early standards (like DVB-T and ATSC) supported SD at the same quality as analog, but also 720p, 1080i, 1080p, and now 4K UHD broadcasts in some regions.
- Consistent quality: A digital signal is either decoded correctly (and looks very sharp at its intended resolution) or it doesn’t come through at all (“cliff effect”). No gradual fuzziness like analog.
- Compression trade-offs: Digital relies on compression (MPEG-2, H.264, etc.), so artifacts can appear with low bandwidth, but resolution is still higher.
Bottom line: Analog TV never matched the resolution potential of digital. At best, analog gave you a softer SD image; digital enables HD, Full HD, and 4K.
