We can't really tell with that test if there is more lag than there should be. Could be either the DAC is laggy, the LCD is laggy, neither, or both. Going by the photos I'm only confident the CRT is between 0ms and 40ms faster than the LCD, which isn't enough information to make a conclusion.since the CRT on the analog port seems faster, can that mean that the analog port on the gtx 980TI has not really slower latency than the digital one? or maybe the LED tested is just slower even with the advantage of supposed faster HDMI digital port? what you think?
If you're using a high framerate v-sync off test(first reaction), a CRT should have an absolute latency <2ms, and a fast LCD can be <5ms. However a timer in the middle of the screen only measures the one point, so the measurement is heavily impacted by refresh rate.(so you need a lot more data to figure out how big the difference is between the two monitors)
It's like trying to figure out if runner A is slower than he used to be, but our only data points are what lap runner A and runner B are on at the moment.
