Our Verdict
Samsung CU8000
Samsung DU8000
The Samsung CU8000 and the Samsung DU8000 are very similar, but there are a few differences. The DU8000 has better contrast and black uniformity, so blacks are a bit deeper on it during dark scenes. The DU8000 also has a much better response time, so there's less blur behind quick motion. However, the CU8000 has better SDR brightness, so it overcomes more glare in a room with some lights on. Colors are also more vibrant and lifelike on the CU8000 due to its wider color gamut and better color volume.
