Are there any particular displays that stand out for performance and quality? I assume the two are not necessarily congruent, meaning, a gaming display may not provide the best image quality, otherwise? Is this so?
If what you mean by gaming display is one with the fastest response time, then yes, there will be tradeoffs for other uses like photo work, video editing, movie watching, etc. Anything where you display real life images, a fast response TN panel with 6 bit color depth is going to fall short of the task.
TN panels don't actually have a 16 million color palette like the advertising would lead you to believe. They have to dither (pixel blend) to synthesize many of the colors, whereas 8 bit panels don't, being capable of a full 16 million separate colors. The result is color smearing and noticeably inaccurate colors on faces in real life movies, videos, etc.
You should probably look for at least a PVA type display, and even those can exhibit color shifting at wide angles of view. It is only the high grade IPS panels that don't have these problems, they're the closest thing to CRT in an LCD. The problem is you can only get limited sizes in IPS and they are fairly expensive.
In the UK there is the Hazro brand that makes a 24" IPS. They're the only ones I know of making one that small. Elsewhere you can get a DoubleSight 26" IPS, and they are down to $600 now. I have the chance to buy one for $500 by the end of Feb because I registered for their newsletter/contest before they had a raffle for that display.
I must say it's quite tempting, though I don't plan to build my next system until the end of the year and I was hoping someone would make a 16:9 IPS.
