The Chinese monitor maker Dasung is now selling its 4th-general monitor, the Paperlike 3, on Indiegogo, for $900. This started out a crowd-funding campaign, but it is already fully funded so we might as well call it a sale with a delivery date in July.
It's not just that the Paperlike 3 has a higher resolution screen (2200 x 1600) but also that its drivers are more sophisticated. (In fact, you don't actually have to install the drivers any more.) With the last model I shared detailed tips on how to get the most out of the hardware by changing system settings in Windows and tweaking apps.
The new model doesn't require as much effort, and in part this is because you can change the contrast on the monitor itself (you can easily change the contrast setting when you switch apps). But after a weekend's use, I have concluded that the tips would still be useful to a longtime user, however.
At $900, the Paperlike 3 is considerably more expensive than its closest comeptitor, the Onyx Boox Max ereader. But it is also a much better monitor than Onyx's ereader.
I think it's worth the cost.
