I've found this much more stable than the Firefox nightlies. Note, don't use Canary. I'm not sure if Beta has the hidpi changes.

On older builds (in particular while I had a X1 Carbon 2 through work, which had a 14" QHD display), I used the command line flags shown here:

The experience was not super, but it was enough to prevent it being entirely useless.

There may also be a setting in chrome://flags in some versions.

On Firefox (although this seems to also be unnecessary in the newest Nightly builds) the setting in about://config is "layout.css.devPixelsPerPx" -- setting that to 2 (for example) would double the size of everything while leaving font rendering smooth.
