Multiple monitors and the graphics card that can't keep up
Four screens, twelve charts, each with indicators. A modern desktop can handle it, in theory. In practice, a weak graphics card or integrated graphics can start to stutter when the market gets busy.
The symptom is subtle. The platform feels slightly sticky in fast moments, and clicks land a beat late. Task Manager shows the GPU at high utilization, or the CPU waiting on rendering.
Screens at different resolutions and refresh rates complicate things. Mixing a 4K display with a 1080p one forces scaling, and some platforms handle high-DPI settings badly, with blurry text or slow redraws.
Cables and ports matter too. An adapter that limits bandwidth can cap refresh rates without warning.
A sensible approach is to build the setup around the platform's needs, not the other way around. Use identical monitors, connect them to a card with adequate output, and keep the number of live charts to what's actually watched.
A stress test helps: replay a fast market in a demo or open many charts and watch for dropped frames.
Trading screens should be boring in the best sense: smooth, predictable, and never the thing that needs attention.
Live charts at once: how many, and was a graphics bottleneck ever found?
