How to setup multiple monitors for trading?

A trader needs a setup of multiple monitors for trading. Because he needs high resolution when he zooms out on a trading graph. This is the most popular necessity in traders.

So mostly the trader uses 4 to 8 monitors at the same time.
If you want to setup multiple monitors for trading. First of all, you need to know your computer has a port like HDMI, DVI, D-sub, and Displayport.


You can easily connect your multiple monitors with the help of these ports.
You will need a product like a USB to display port, a VGA hub, and an HDMI hub to connect many monitors, such as you can easily connect all those Monitors.

How you connect your laptop to multiple monitors for trading?

When you start to connect your monitors then if already VGA port available on your laptop and your monitor port is also a VGA port.

So you can easily connect it. This method is just for one monitor to one laptop.
For connecting multi monitors you need a product HDMI hub and VGA Hub. This product will help you to setup multiple monitors for trading.


This is the easiest method for the setup of multiple monitors.

There is probably no choice, the creation of a 4-8 display configuration is the only opportunity to simultaneously follow the main trends.

The whole question here is how to setup multiple monitors for trading – buy a lot of cheap video cards or a little more expensive, but with a large number of connectors, or give preference to a specialized solution for multi-display configurations.

Some users who, due to budget or space constraints, have one computer for two, are considering connecting a second monitor for simultaneous use of the PC by multiple users.

Requirements for Multiple monitors setup for trading

It is desirable that all displays used at the same time be as identical as possible – have the same size, resolution, height, tilt, screen quality, and, if possible, narrow frames.

It is also highly desirable that they have several different modern digital connectors (DVI, DP, HDMI), which will expand the possibilities of their simultaneous connection to different connectors of the video card and motherboard.

If you want to create a frameless or multi-display system, then the monitors must have special mounts (VESA type) to securely connect them to each other on a bracket that must be selected in advance.

Some manufacturers (eg DELL) have displays that support Multi-Stream Transport (MST) technology specially optimized for creating multi-display configurations.

They not only have thin frames, but they can also be connected to a PC with just one DisplayPort (DP) cable, and then they are connected to each other with the same cable through the DP connector.

Those. only one cable is connected to the computer, which is very convenient and does not require additional connectors on the video card. 

Up to 4 displays with Full HD resolution (1920 × 1080, 1920 × 1200) or 2 displays with resolution 2K (2560 × 1440, 2560 × 1600) can be connected to one video card connector so that the total resolution of all monitors does not exceed 4K (3840 × 2160, 4096 × 2160). 

This limitation is caused by the bandwidth of the DisplayPort v1.2 standard.

How to connect multiple monitors to one PC

Connecting two monitors with different interface connectors to a computer with a modern video card usually does not cause problems.

 They simply connect each to its own video card connector, the maximum is that you need to buy the corresponding cable if the one you need is not available.

Problems start when there is no suitable connector on the second monitor.

In some cases, this can be solved with an adapter or a special cable (DVI-HDMI, DP-HDMI, etc.) – this is the simplest and most correct solution.

But, if the monitor only has an outdated VGA (D-SUB) connector, this can be a real problem. The fact is that old video cards had a DVI-I output with the ability to connect such monitors via a DVI-VGA adapter.

Modern video cards use a DVI-D connector, which does not output an analog VGA signal and there are no corresponding outputs for connecting such an adapter and it is impossible to connect a monitor through it.

Yes, there are special converters (DVI-VGA, HDMI-VGA), but the image quality suffers greatly during conversion (the picture becomes soapy, the color rendition deteriorates), so this is a bad decision.

Modes of operation of multiple displays

Monitors connected to a PC can operate in several modes, the simplest of which is screen mirroring.

In this case, the same image is displayed on all displays (as when connected through a splitter, but then it also deteriorates in quality).

This mode is usually used to output images to a TV for watching videos or from a laptop to a monitor for working on a large screen.

The second mode is desktop extension, in which the entire workspace is evenly divided across all connected displays.

In this case, you can drag any window to the desired screen and arrange them as you like.

In this mode, you can also stretch one window over several screens, which will be useful when working with large projects (design, video editing), watching videos, and playing games.

In general, this model is flexible enough to allow you to display the image however you like.

All settings (location, resolution, operating modes) of the monitors are located in the “Settings” snap-in on the “Display” tab.

Here you can change the layout of the screens by simply dragging the mouse.

And just below you can select the parameters and modes of operation of multiple displays, everything is done very simply and intuitively.

As for the simultaneous use of a computer by several users, it is possible, but with some restrictions.

For example, one user can work, play, surf the Internet, while the other can watch a movie online.

At the same time, it is possible for each user to use not only a monitor but also his own mouse, keyboard, and even headphones (everyone will hear their own sound).

But this use of a PC assumes that one of the users will be in a passive mode with rare use of input devices (mouse, keyboard) since they work synchronously.
