Using Chromecast, displaying Google Photos has a resolution limitation of 720x1280, according to Google official developers documentation.
This amounts to less then a single megapixel, while TVs today generally output 2160x3840, which is over 8 megapixels. The current state is close an order of magnitude loss of fidelity. I've seen several year old feedback on this, and I'm bewildered that the situation is static.
So there is a huge opportunity to make Google Photos immensely more enjoyable by supporting the actual resolution of the source material, combined with the supported 4k resolution of TV sets.
Google Photos with webinterface on desktop is fantastic, as it uses the full resolution of the source material and of a monitor. Pictures immediately look sharp, and when zooming in, you can see the software buffering lightning fast to show the full information available. A true pleasure. In other words, the Photos team has the backend implementation ready to dynamically handle variations in both input and output resolution to offer the optimal experience.
The next piece of the puzzle is that 4K TVs are almost without exception the largest and highest resolution screen in a house. To support the best screen in the house is a no-brainer use-case. In the link above, users have already expressed the impact this has on sales.
My feedback: please reap these lowest of low hanging fruits!
Now imagine also supporting HDR photo formats on Google Pixel and Chromecast, and the viewing experience this gives on modern HDR screens! Google Photos has an immense opportunity.
