We already reviewed Lenovo's new ThinkPad X1 Extreme with the optional 4K HDR screen. It is a good screen, but there are some drawbacks as well, so we were eager to find out how the standard 1080p display of the entry-level SKU performs. We already have a test unit and want to compare the basic measurements of the two models ahead of the complete review.
