There are also 21.3 inch IPS and VA 4:3 panels made. They are in models like the NEC 2190, the Samsung 213T and 214T and some others as well. They are the biggest ever in LCD 4:3
I prefer the also no-longer-made 25.5 and 27 inch 16:10 models. They are even bigger for 4:3 images, yet not too wide. It still looks pleasant to the eye. This size was also available in IPS or VA, even with wide-gamut: it gives an image quality that is no longer made, sinds LED-backlight does not offer the awesome colours. Screens to look for: Dell 2707, Dell 2709, Samsung 275T, Eizo 2731sx, Acer 2623 or 2723, Nec 2690, Hazro 26w, Planar 26something, LG W2600HP. These 25.5 and 27 inch beauties are BTW mainly targeted at Europe. USA-ians did not care ---steaming pile of meadow muffin--- about image quality, so they did not get most.
