Aside from the extra buffer from the THS7374 the THS7314 and THS7374 are almost the same. However, on the board I use a different voltage divider for red compared to green and blue. You can see in the measurements that red has a lower Vpp coming out of the S-CPUN than green and blue. The simple correction with the 1.1k resistor at every R,G,B wire to ground (parallel to the existent ones) won't change that. What you can observe is that the color feels a bit different if you compare both methods.
