According to that comparison the L194WT has better viewing angles, a slightly higher ppi (dpi) and costs less. It also offers HDCP and a sRGB profile (though those are often badly calibrated anyway). Video will have the advantage of stretching better to 16:10 than 5:4 (smaller black borders).
On the other hand the L1970HR displays slightly more pixels (14720, not really a big difference) and in case you're playing lot's of 4:3/5:4 games (like Battlefield) you will have a smaller picture with black borders on the widescreen display.
