You actually do have a screen with 50k pixels. Many more than that.
A continuous heat map over two dimensions, at 500x500 pixels, is 250,000 pixels. Of course, to generate the heat map, you have to aggregate (binning on two dimensions), but you don't have to downsample.

Right. I was thinking only of time series.
