I’m currently trying to run four monitors off my 4070 GPU: two 1080p screens at 180Hz (which I’ve reduced to 60Hz), one 1440p ultrawide at 165Hz (also down to 60Hz), and a 1440p monitor that I want to keep running at 480Hz. However, whenever I connect all four, one monitor just won’t turn on. I’m wondering if I’m hitting some kind of pixel limit on my GPU and if there’s any way to work around this? I have the most demanding monitors connected via DisplayPort and one 1080p screen via HDMI.

First things first, go into your Windows Settings and make sure that each monitor is set to “Extend” rather than “duplicate” or “disabled.” Also, check if it’s always the same monitor that’s going black—if it is, ensure it’s set to the right input. If you swap cables or ports and still have the same issue, that might indicate trouble with a specific monitor or cable. Lastly, double-check the model of your 4070; some manufacturers limit the number of active outputs to save on costs.
It sounds like you might be facing a resolution issue rather than a pixel limit. GPUs don’t have a general “max pixel limit” but rather a max resolution for each monitor. So making sure that all monitors are set to their maximum resolution is key. You should be able to run all four monitors at their default settings as long as they are set correctly.
Yeah, I’m just trying to get them all to work without dropping the quality too much.
That makes sense! Just to confirm, have you checked the settings on each monitor to ensure everything is set properly?
