I'll be either creating a short video or long post here about the following subject: video player image quality.
The Dashcam may record perfect 1080p or 1440p resolution MP4 footage but -some- Media Players display poorly, distorted or nothing at all.
MP4 is very commonly supported these days but not with older Media Players. My point is don't fully trust the playback quality from your Program, instead view the footage on many different and recommended Players for your OS. Another tip is to copy MP4 footage clips to USB stick and play from SmartTV, they all support MP4, only issue is with 1440p (2K) resolution clips on 720 or 1080 LCD TVs. Once you determine which Media Players display best use that for all viewing. Always test with bright daylight to check focus, remember to clean both sides of windshield, if you have a sun/moon roof park infront of building and record through windshield then while holding out roof in your hands to confirm the windshield isn't the blurry cause. Suggest using strong flashlight to shine into dashcam lens while off to reveal smudges or streaks.. see my Lens Cleaning videos for effective method..
