I realize that this may not be specifically related to your query...
While the size and weight may be more than you are looking for, after playing on multiple different display technologies, I've really been nerding out on my older plasma displays.
They are a middle-ground between CRT and OLED, usually have a wide selection of legacy input options and can be found dirt cheap on the 2nd-hand market. After doing the lag compensation on one of the guitar games on console, I was surprised to see the lag compensation number come up at 0ms! I think I would be surprised to see that even on a modern OLED. And to top it off, little if any "motion-smear". YMMV depending on the set, but the higher-end Panasonics are usually the best to be on the lookout for.
IMHO, if you can deal with the weight and power consumption, they are still one of the best 16:9 format display options for classic (and even modern) gaming, especially if on a budget.
