About Missing dots

I have been using it for about a year. However, about 3 months ago, missing dots have been seen. Can I repair it with a warranty?

Do you have any symptoms of missing dots?

Hi @20centuryboys We regret to hear you are having issues with your VAVA 4K UST Projector. Would you be so kind to try the following steps to see if it solves the issue?

Please try performing a factory reset by going to Settings> General> Factory Reset.
Once the projector is reset, please make sure that the projector has the latest firmware.
This can be done by going to Settings>General>Update version. Please update the projector if it is not up to date.

If the issue is still not fixed, kindly take a video of it and send it to support@vava.com. Thank you!
