The best monitors for trading.

Charts, order entry, news and a watchlist, all visible at once, without a bezel cutting through the middle. Our picks from the Deco Gear lineup.

227-inch QHD screens’ worth of space on one 5120 × 1440 panel
0bezels down the middle, so a chart can stretch across the full width
2computers on one screen at once with picture-by-picture
What matters

Three things to look for.

Width without seams

One 5120-pixel-wide panel shows two QHD screens’ worth of charts with no bezel in between.

Two computers, one desk

Picture-by-picture shows a work PC and a personal machine side by side; a built-in KVM shares one keyboard and mouse.

Contrast for long sessions

QD-OLED blacks are true black (1,500,000:1 typical contrast), which keeps dense dark-theme charts readable.

Questions

Answered.

Is one ultrawide better than two monitors for trading?

For most setups, yes: a 5120 × 1440 ultrawide has the space of two 27-inch QHD monitors with no bezel through the middle, so a chart can run the full width. With picture-by-picture you can still split it into two inputs.

Can I show two computers at the same time?

Yes. The 49″ 5K and the 49″ QD-OLED support picture-by-picture, and both have a built-in KVM so one keyboard and mouse controls both computers.

How many monitors does a trader need?

It depends on how many windows you watch. One 49-inch 5120 × 1440 screen replaces two 27-inch QHD screens; some traders add a second screen above or beside it. The 49″ 5K and 49″ QD-OLED mount on standard 100 × 100 VESA arms.
