Sadly more $$$ may be needed.

Calibration works better with better screens, = more darn money.

The commonest screen is TN (twisted nematic) type because it is cheap to make and the contrast/saturation/colour appears to change as you move you head around, despite careful calibration.

The good ones are IPS (in plane switching) type and used to cost many times the price of the TN types, but luckily now I have seen LG brand IPS screens advertised for much more sensible prices.

The IPS screen stays with constant contrast/saturation/colour as you move your head around and also have a better colour gamut than the TN types. They are usually listed as "178 degrees viewing angle".

My various TN screens on notebooks in the house maybe can display 60% to 70% of the sRGB colour gamut, as long as your head is held square to the screen.

A decent (read expensive) thing I bought is the 24" Asus ProArt 1920x1200 IPS screen and will display practically 100% of the sRGB gamut plus make my E-PL1 look like a way better camera.

There's a big difference in the quality of the image displayed.

Monitors like that come with selectable profiles and do have a canned sRGB profile but of course proper calibration improves on that by varying degrees.

Keep saving those $$$$$.
