Is a 4K front dash cam worth it over a 2K (1440p) model?

Specialist testers we read are split. Independent dashcam forums repeatedly point out that some budget '4K' cameras use upscaled or 'fake 4K' sensors that don't resolve much more real detail than a good 2K STARVIS 2 sensor, and several record 4K at reduced frame rates (25-30fps). If clean, smooth footage and reliable plate capture matter more than the spec sheet, a well-implemented 2K HDR camera often satisfies. True 4K front sensors mainly help when you frequently need to read plates from a distance in good light.
