Hi ehsan_sarshar and thanks for contacting us.
We understand you're concerned about the resolution of your new Quest 3 and we would be happy to provide some tips to ensure you have the best possible VR experience.
First, clean your lenses: using the dry, clean microfiber cloth, start from the center of the lens and gently wipe the lens in a circular motion moving outwards.
Next, adjust the IPD or set it correctly: IPD stands for inter-pupillary distance, meaning the distance between your pupils. To change the lens spacing on your Meta Quest, gently move the slider under your headset until your view is clear and comfortable. If you know your IPD, this table shows which lens spacing setting we suggest.
You can also check in-game settings as some games may have their own resolution modes and setting that can be adjusted.
These tips should help make your VR environment less blurry and pixelated, however, if you require further assistance, please feel free to get back in touch. You can also send us a private message by select our name to get to our profile page and clicking "Send a Message." Please remember, you must be signed into the community first to send us a private message.
Have a good time in the Metaverse and remember, we're available 24/7 if you need us!
