That depends partially upon application but I'll assume you mean high fidelity to life. In that case, computer monitors can be very nice because they weren't designed with the limitations of over the air broadcasts in mind, since the image was locally sourced. Therefore, computer monitors usually have the lowest dot pitch and highest resolution support.
There are several caveats though. One is that they don't support standard definition signals natively, so if you're using them with S.D. sources you'll want an external upscan converter, which basically upscales the image. The other is that what's typically considered a true computer monitor has a maximum size constraint of approximately 20" viewable area, which is likely because they were designed to be viewed up close at the work desk (There were some 24" 8:5 models but these won't make the viewable 4:3 area any bigger).
If these restrictions don't bother you look into FD Trinitrons and later Diamondtrons: Those are truly flat glass models, which should minimize geometric distortion, with aperture grilles which should maximize potential brightness and give more consistent pixel arrangement. You might want to look into the N.E.C. MultiSync FP2141sb. Other noteworthy models include the LaCie Electron Blue IV and the Sony GDM C520k. These are all 20" size class monitors with a recommended resolution of 1600x1200 but could also support Q.X.G.A. (2048 x 1536).
