> I've actually had someone tell me that no monitor during the XP era would've been a CRT

That person is incorrect. WinXP started selling at retail in Oct 2001. I started using it at work in early 2002 and as a senior employee in a tech company I had a pretty deluxe 21-inch Viewsonic CRT which ran at 2048 x 1536 resolution. That Viewsonic cost $1600 new in 2000 and looked great. The company didn't upgrade to flat screens until about 2006 when the Viewsonic was replaced with a 20-inch Dell 2005fpw with native 1680 x 1050 resolution for $800. That's the year Windows Vista came out.

Even in 2006 corporate priced LCDs at the 20-inch size didn't look quite as good as the high-quality CRT I switched from. In some ways (like sharpness) a good LCD could look better but in other ways (like contrast) it wasn't as good yet - so it was still a mixed bag. About 2004 the company started buying newly hired entry-level employees 15 or 17-inch LCDs but they were typically 1024 x 768 and the quality wasn't great. A designer like you would definitely have stuck with a CRT longer both for quality and screen size at a reasonable price.
