DLP televisions are fully capable of displaying 1080p. LCoS does *NOT* offer any higher resolution than DLP, and suffers a slower response time and lower contrast levels than does DLP.

DLP response times are measured in microseconds, whereas LCoS, being an LCD based technology, offers response times in only milliseconds.
Many lamp based DLP units offer 10,000 to 1 contrast ratio, and the new generation of LED based DLP units offer up to 100,000 to 1.
The LED based units have a lamp life in excess of 40,000 hours, and a wider color gamut than any other technology available, including lamp based DLP.

The only advantage that LCoS has is that the they tend to have a brighter picture…but this leads to a significantly shorter bulb life.

Please, do a little research next time. Your claim about resolution is completely wrong.
