LCD monitor display quality depends on the video source, though performance varies with the brand you own or buy. Across monitor types, video source quality depends on 6 factors:
- Resolution
- Bandwidth
- Signal quality
- Cable & connector quality
- Sharpness & Focus
- Electronic component stability (capacitors, circuit boards, SMPS, etc.)
In my own experience, Samsung, Apple and Sony have some of the best performance monitors for PCs & laptops while LG monitors are cost-effective alternatives.
