Problem with graphics after buying a new PC and monitor

[equu]

I recently got a new PC and a 34" ultrawide monitor (3400×1440), but the graphics look really off. When the image is still, everything looks pixelated and jagged. As soon as I start moving, it becomes extremely blurry - so much that I can’t even tell what items are on the belts until I stop. There also aren’t many graphics settings to tweak (like resolution), so I’m not sure how to fix it.

This sounds like a “Motion Enhancement” feature on your monitor.

Tell us which monitor. It sounds like it is simply too slow, like many VA panels.
Often there is a option "Overdrive" which you might try playing around.
Also it's better to NOT use VRR for Factorio, else monitor Hz is locked to 60 Hz which again is bad for motion blur.

Also please show Display panel settings in your OS showing currently used resolution and refresh rate.
