Hello, I have a question for anyone who might know.
I want to use a Framework laptop board to run four small screens at 120Hz, or at least 60Hz (with a maximum resolution of 1080p, although the screens res can be smaller).
Thank you for your replies.
If it doesn’t work and you’re running Windows, another option could be a DisplayLink adapter. It technically works with Linux as well but is more difficult to setup than just installing a driver.
Note however that I’m not recommending this or any DisplayLink adapter, as I personally avoid them; personally I would only use one if absolutely necessary as several (6+) years ago I had to use it at work and it would always crash at inopportune times. That and I’m using Linux 99% of the time and don’t want to deal with getting it working with Wayland. Therefore I’m mentioning it merely as a possible option to achieve whatever it is you’re trying to do.
Both those platforms support 4 displays and the resolution/refresh rate is mostly a bandwidth limitation at that point. You should be able to run at least 3 1080p60 displays over even an ancient DP1.2 mst hub without dsc.
The minimums Intel guaranteed for most 11th gen Core processors are 4x 4k60 or 1x 8K60.
FHD@120 requires less bandwidth than 4K60 (around half of it actually). So yes, easily. And those minimums are regardless of memory. So with appropriate memory config, you can easily exceed the 4K60 per monitor (somewhere above 8K30 or similar you need to expect one output to consume the hardware of 2 outputs, because that is what Intel uses to reach 8K60 bandwidths).
New Intel CPUs are even increasing the total limit to include 4K60+8K60 as the top guaranteed minimum.
We do not know where the actual practical limit on total bandwidth across all monitors is and for which memory config.
