Multi screen problem

General Discussions
1

I wish to follow live three different indexes.
For each index I have a workspace, so 3 workspaces.
For each index I have 5 windows. So in total 15 windows.
I have three 34 inch monitors. 3440x1440.
So for each index I have a 34 inch monitor.
I can use Nvidia Mosaic to connect the three monitors in one landscape format.
I should then put the 15 windows in one workspace that covers the three monitors.

Problems:

  • I cannot open three workspaces simultaneously, so I have to make one workspace with the full content of the three individual workspaces. So 15 windows. And then I put each index on another screen.
  • For the graphic card I need to know what the resolution of that card should be: 3440x1440? Or 10320x1440? The graphic card has 3 Display Port outputs.

Is there anybody who did something similar?

Not I. You have me beat with my one chart taking up half my 34 inch monitor.

Willing to help. I’ve used Nvidia Quadros with multiple monitor setups in the past and predecessor to Mosaic, can’t recall name but same thing.
Graphics card resolution: ‘I need to know what the resolution of the card should be’ - the card doesn’t have a resolution as such, the ports and number of determine what it can support. You have 3 x Displayport each of which can support one of your monitors at full resolution so you’re good to go (given that mosaic is for RTX Quadros they’ll probably do 3 x 8k res if you had it).

You don’t have a problem with what you’re planning to do. If I’ve missed or misunderstood something, elaborate….
Best,

Multi-monitor graphics cards don’t quote a ‘combined’ resolution, so you’re looking for a minimum of 3440x1440 support – if the card supports multiple monitors, each monitor output port should support the same resolution.

I’ve used this 6 monitor video card,
VisionTek Radeon HD 7750 2GB GDDR5
$192 USD on Amazon

This is a newer version of the same card,
VisionTek AMD Radeon RX 580 8GB GDDR5
$237 USD on Amazon

Both cards offer 6 Mini-DisplayPort outputs for multi-monitor setups. You’ll probably need to purchase 6 adapters (I currently still use my DVI-to-MiniDP adapters), so research available options and factor in the cost for 6 of those as well.

I never saw the need to ‘connect’ multi-monitors into one giant landscape, Windows does a fine job of handling all my monitors just fine – I can move my mouse seamlessly across all monitors, and Windows makes moving individual windows across monitor boundaries a breeze.

For easy layout and placement/resizing/positioning of windows using hot keys, I have enjoyed WinSplit Revolution on Windows 7, but it’s no longer available. It’s been rebranded into something called MaxTo.

I have also used special multi-monitor software, mostly UltraMon, but I think I’ll switch to DisplayFusion eventually. On Win7, UltraMon was especially helpful because it provided a taskbar on each monitor – and it only showed taskbar buttons for the windows resident on that monitor.

I hope DisplayFusion combines the best of both worlds. But I absolutely can not live without my WinSplit Revolution hot keys to auto size my NT chart windows – so, if DisplayFusion doesn’t do that part well, I’ll be checking out MaxTo.

Yeah, you’ll need everything saved into one NinjaTrader workspace, so design and layout all your 15 windows across all your monitors and then save into a workspace. Easy peasy, esp using auto-sizing & auto-positioning software, like WinSplit Revolution, or MaxTo.

In case I didn’t say it well enough, I absolutely love WinSplit. Precisely because I have multiple monitors and precisely because all NT windows are completely independent windows and thus can be re-arranged quickly with the default WinSplit hot keys. I have high hopes for MaxTo, but have not tried it yet.

Good luck!

TO: brucerobinson and bltdavid:

Thanks for your very helpful confirmation of what I was thinking.

I got confused because of Chatgpt, that proposed me cards in a range of $5-10K. So I needed some confirmation after Chatgpt giving me several strange answers.

I bought my first dual screen Matrox card around 2000, together with two 17” screens. At that time almost nobody knew that they existed. So I am familiar with them. But as I did not follow the technical evolution anymore, I was not sure what to do.

I was assuming that adding up the resolution of the three cards resolutions was wrong. I was thinking that each DP output gate would serve just one screen, so why add up the resolution of all screens? You both confirmed my opinion.

Because of the way Ninjatrader is build I need a three monitor landscape as all 15 charts (windows) need to be together in one workspace. As I will use a Nvidia card, and as they have special multi-monitor software for their own cards, I will use Nvidia Mosaic.

But I will first try out my “MINISFORUM UM890 Pro” computer, which pretends to support four 4K screen simultaneously. Later I would like to switch to a more powerful CPU (AMD Ryzen 9 9950X3D).

Thanks to you both!

You’re welcome. You say you have an Nvidia card and will use Nvidia Mosaic, so I’ll take a guess that you have an RTX card. If so, you may want to seek out Nvidia Desktop Manager software also, and combined you will be able to do all the wonderful things David describes but without 3rd-party SW add-ons (I believe Mosaic works only with Nvidia-based ‘Professional’ cards Quadro & RTX, Desktop Manager only with RTX). Can’t vouch for either but in the past have used their predecessors with Quadro cards and they were extremely comprehensive and robust (Desktop Manager is designed for managing financial markets workflows, and others).
Good luck

My tiny mini PC from Amazon can support 3 x 4K displays and was like $400.

What you’re trying to do is feasible, and you’re thinking about it the right way. A few clarifications may help.

1. Workspaces vs. displays
Operating systems (especially Windows) cannot show multiple virtual workspaces at the same time. So your conclusion is correct: if you want to see all 15 windows simultaneously, they must live in one workspace, arranged spatially across the monitors. Virtual desktops are for separation, not parallel visibility.

2. Mosaic vs. independent monitors
Using NVIDIA Mosaic will make the OS see the setup as one ultra-wide surface. In your case that surface would be:

  • 10320 × 1440 (3 × 3440 horizontally)

That is the logical desktop resolution when Mosaic is enabled.

If you do not use Mosaic, then:

  • The GPU still drives three independent 3440 × 1440 displays
  • Window managers can snap windows per monitor
  • You can still place 5 windows per screen without Mosaic

For most trading setups, Mosaic is not required unless the software itself demands a single contiguous surface.

3. GPU resolution requirements
From the GPU perspective:

  • Physically: 3 × DisplayPort @ 3440 × 1440
  • Logically (with Mosaic): 1 × 10320 × 1440 surface

Modern mid-to-high-end NVIDIA cards handle this easily. The key specs to check are:

  • Maximum desktop resolution (well above 10k × 1.4k on recent cards)
  • Total pixel clock / bandwidth (3440×1440×3 at 60–100 Hz is fine)

4. Has this been done before?
Yes—this exact layout is common among:

  • Traders monitoring multiple indices
  • Control-room / ops dashboards
  • Simulation and data-analysis setups

Most experienced users eventually avoid Mosaic unless strictly necessary, because:

  • Window snapping and taskbars behave more naturally per-monitor
  • Fewer edge cases with fullscreen apps
  • Easier recovery if one display resets

Practical recommendation

  • Use one workspace
  • Keep three independent monitors (no Mosaic unless required)
  • Arrange 5 windows per monitor
  • Let the GPU drive 3 × 3440 × 1440 via DisplayPort

Mosaic is optional. The resolution your card must support is trivial; the decision is really about window-management ergonomics, not GPU limits.

I have this one: Mini PC|MINISFORUM UM890 Pro
It’s the only one with liquid metal cooling. Heat is many times a problem, but with this one not anymore. I can run four 4K screens. I use it when I travel because it is 50 times smaller than a desktop and has even the same performance.

I use four 4K screens (currently, they’re 32" but it has changed over time) on my main workstation, and dual screens on all of the others. I’ve tried a lot of different configurations, and this is a pretty productive arrangement for the way I like to work. I’ve found that having one gigantic screen isn’t productive without adding a lot of aftermarket software to snap things to little blocks of space (Windows by default only snaps to quadrants as the smallest division) and I don’t like adding any more aftermarket software than I have to because then I can’t be certain when I see strange behaviors whether I’m seeing something that’s just an artifact of what I’ve done to Windows with the aftermarket software. So, four screens is a decent compromise - that gives me sixteen little “snap” areas where I can dock something, which is more than I usually use (often, I only use 4-8). So much depends on your workflow, and what you are doing, and also how comfortable you are with tilting or turning your head or even your shoulders or your whole body (which can happen if the screen space gets too big relative to your distance from the screens).

One other thing I would add is then when doing development/testing, often I will keep some of my screens at HD resolution rather than 4K, because it’s more common for end users to be running 1920 x 1080 than anything else, and I need to know if things work and look reasonable at that resolution. That’s in fact more important than jamming more small text onto the monitor (to me).

With Miscrosoft’s PowerToys one can create window grid to snap windows to. PowerToys also has (windows) workspaces feature which may be of interest to you.

Windows can combine multiple monitors into one virtual desktop, I’m not familiar what Mozaic does. Each monitor should run at it’s native resolution. Like @marcus says, even PC with discrete GPU (like Ryzen 8945HS) can drive multiple monitors w/o a problem.

My Mini PC has a AMD Radeon 780M GPU. Max resolution 4096 x 2160 for each screen. I run it at this moment with two 34" screen at 3440 x 1440 without any problem at all. And I have two USB4 connections on which I can add two extra screens with that same resolution (did not try that).
All this under W11 without any problem and without any additional (needed) software.
So I was surprised that Chatgpt told me to take very expensive GPU’s (between $5 and $10K), and mentioned other nonsense. As I never take AI for the holy Bible I double checked their info, and it is now clear that AI sometimes creates Artificial Nonsense instead of Artificial Intelligence.
I just need charts, no video’s or gaming.

Personally, I would be careful with these mini pc purchases. If you search on Youtube, some have been found with factory installed spyware.

Yes. I use 4 monitors. I have one Workspace that displays my 3 futures: Q-R-S for my live account divided into one each on 3 monitors and on the 4th I have my control center and reports. My BACKUP system is from 2016 (Win 10) and has an NVIDIA GeForce GTX 960 (2 GB; 1080) card and the displays are just 1080p and are as crisp as anyone would need. My main system (Win 11 from 2024) is an upgrade using 4K monitors and an NVIDIA GeForce RTX 3080 (10 GB; 8K) card. Total overkill and not really needed. Moral of the story: you don’t need a high-resolution card for a crisp, multi-display NinjaTrader setup.

You mean spywear like used by Microsoft, Google, Facebook, Snapchat, Apple, Whatsapp… who are stealing, abusing, selling all your personal information?

I found even messages on internet about Tradestation…

Do Chinese Mini PCs Have Spyware?

Not really. The vast majority of Chinese mini PCs from reputable brands like Beelink, Minisforum, and GMKtec do not contain spyware or malware.

Is Beelink safer than Minisforum, or vice versa?

Both brands have excellent security track records with no reported malware incidents. They’re effectively equivalent in security terms. Your choice between them should be based on hardware specifications, price, customer service reputation, and specific model features—not security concerns.

You do you. Let me know when you see the companies you mentioned have software that steal your passwords, files, various credentials, tries to evade antivirus software and more from your system.

I have proof that Google gave the government access to one of my 2FA email addresses at Google. I have screenshots of the actual moment when it happened with the IP address of the intruder and the exact time when it happened.
I went to a cyber security department of the government and also went to court. The case was dismissed and I never received any explanation. I was able to trace back the IP address, which was from a tax department. I never got accused of anything as there was nothing illegal going on with that email address. I immediately created new email addresses outside the countries who help each other to invade in our privacy. The so called Five eyes, Nine eyes and Fourteen eyes. I also installed a VPN with a company outside the before mentioned areas. I have only three email addresses, that I never use. I use aliases, so nobody can ever find out my real email addresses.
Just keep on dreaming that the US is not spying, but that China is the only danger.
All this happened 10 years ago.
If I go on internet, depending on which server in which country I log in, I get publicity in the corresponding language. So it changes constantly between English, German, French, Norwegian, Russian, etc…

I am not going to waste a lot of time, so just a few examples of the real world.
Just Google the internet and you will find everywhere proof. Just a few examples:

Which one of those companies installed spyware onto your system to “steal your passwords, files, various credentials, tries to evade antivirus software and more”? “Just keep on dreaming that the US is not spying, but that China is the only danger.”… I never mentioned anything about any country. I think it’s naive to assume that companies, especially social media companies, won’t share your information from their system with a government entity. That is different than companies factory installing spyware on consumer purchased products.

I must admit they did not steal my password, they just skipped with the same result as stealing it.

Minisforum is Chinese. If you even did not know that, how could you then make a intelligent statement they are a danger?

I see that it’s difficult for you to understand the difference between a company factory installing spyware on a system compared to a company that may give your information to a government entity from their system. My comment was to “be careful with these mini pc purchases”. You are the one projecting your bias based on my comment.
