I'm trying to wrap my head around what my GPU can handle when it comes to multiple monitor configurations. I've done a ton of reading, especially regarding gaming performance, but I can't find much info specifically about monitor setups. I want to know how to assess a GPU's specs to see if it can support setups like three 27" 1440p monitors at 120Hz each, or a combination of a 38" ultrawide 1600p 240Hz and a 27" 1440p 120Hz monitor.
Is it all about the gigabits per second that the GPU can deliver versus the requirements of the monitors? How do I correlate the specs of GPUs with those of the monitors to determine what's feasible? I understand that there might be other factors, such as cable types and docks, but my main goal is to get a better understanding of GPU capabilities. This setup would mostly be for productivity, especially for trading with fast-moving charts, but I also want to game on the main display. Oh, and just to clarify, this is for a laptop, and I'd be connecting everything through a Thunderbolt 4 dock.

When you mention running multiple monitors at full potential, are you planning to game across all of them? It’s important to know that while a GPU might list a max resolution, you often won’t get the same performance across multiple displays. Generally, for high-end GPUs, you could expect around 4x 4K at 240Hz, but once you start stacking multiple monitors, the performance will dip, especially with higher resolutions like 1440p. So gaming on three 1440p displays might not yield the same framerate as just one 4K monitor, given the increased pixel count.
You're right, one port typically means one monitor. If your GPU has three HDMI ports, you can connect three monitors, as long as they support HDMI. There's no need to worry about bandwidth splitting across multiple monitors; just hook them up straight to the outputs.

To get a grip on what your GPU can do, just Google the GPU name and check the official specs. For example, an RTX 5050 might state it can handle 4K at 480Hz or 8K at 165Hz with DSC. That gives you a solid idea of what resolutions and refresh rates it can support. For practical comparisons, sites like TechPowerUp also detail the outputs available on your GPU. Just keep in mind, newer GPUs tend to support modern displays really well.
Just remember, although you can show a static image at high resolutions, gaming at those resolutions may still be a different story.

Basically, your GPU can usually run one monitor for each output it has. The catch is that the quality of the output matters. For instance, if you're using HDMI 2.0, you'll be limited to 4K at 60Hz. But with HDMI 2.1, you can push that to 4K at 120Hz or more, which is a lot better when you're running multiple monitors.

That makes me think since I'm comparing the 5070 TI and the 5070. Does that mean I can't exceed 120Hz across multiple 1440p monitors combined or separately? I plan to use them for productivity with fast-moving graphs but will game on just one. Also, I edited my post: this is a laptop and will run through a Thunderbolt 4 dock.
