The contrast control on my 19" Hitachi CM752ET CRT display is now approaching maximum when calibrating. If I cannot correct it then looks like its on end of life. I already have a 17" TFT extended display but I prefer using the CRT as Primary for Photoshop use.

As I see it I could:

(a) Use the displays external controls to lift the R, G and B settings. These are set to give grey with 6500K white point and Hitachi phosphors and I have no tint just now.

(b) Seeing if there is an internal contrast (voltage) adjustment which will boost the guns individually or together.

Of course in trying (a) if one of the guns is already at max then I will never get proper display hardware calibration.

I don’t think Hitachi supports CRTs any longer.

Similar problem with my 4 year old Mitsubishi 2070. Calibrating with Spyder2pro requires contrast and brightness be set to 100%. It’s just getting by but I think it’s about time to bite the bullet. CRTs are relatively inexpensive these days ‘tho.

My 5 year old mitsubishi 2060u has brightness of 50% and contrast @ 79%.

Calibration is with Spyder 2 Pro.The thing is nearly as good as the day I got it.

Monty,

Is viewing at 100% contrast too bright?

How are you calibrating? I believe seat-of-the-pants calibration was to crank contrast to 100% and then adjust brightness until the deepest blacks could be discriminated.

I am looking to buy a new monitor for use with Photoshop. Any recommendations? I’m currently using a Sony GS420 but after 6 years, it’s getting a bit tired.
