I'm using a Samsung 8.7" tablet as a car head unit, and it looks blurry if I look closely, when driving it's not so noticeable since there is about 1m distance. But I'm planning to upgrade to a 10-11" tablet, then it will definetly more noticeable

Update (05-Dec-24): I did buy a 12.1" tablet and it definetly more noticeable, the kinda pixelated/blurry album art
