macuser: LED doesn't actually provide anything positive to LCD accuracy, at least not several years ago anyway. ?CCFL backlights are usually more able to deliver more?accurate?colour, due to them being a more mature form of backlight and I guess more adaptive? ?Only problem is that they 'drift' over time, for example slowly colour shift and get dimmer, and they are also less bright than most LED displays.
Dell is the best in my opinion before you go to a super high end display, but only the high end Dells. ?U2410 for example. ?Also if your Spyder provides an option to sample ambient light, In my experience it just messes everything up.
6bit v 8bit is important, but not as important as a calibrated display - unless you are working with very large commercial clients, it's unlikely that they will have the technology to see the difference. ?Remember that if you are using a laptop, Display port offers higher quality image via large bit depth, then DVI/HDMI, then VGA. ?
Also remember that if you are going to be using a laptop with Nvidia Optimus, it constantly will mess with your calibration, but there is a work around which you can find on google.
You can also can make things better for yourself if you always edit in 16Bit, which is higher than most cameras, but it allows you to have more flexibility in photoshop with intensive edits - If you are doing consumer work though - Probably not a big deal. ?Edit in Adobe RGB 1998, BUT remember that Adobe RGB has a larger amount of gamut, or colours than a regular consumer monitor so the image will look crap for most people and the web if you don't convert to sRGB first before delivery to client. ?If you are dealing with a commercial client then deliver in whatever format they ask for, and if they don't ask for a format, sRGB.
Yes you are right, and I think that is the reason why the dell 2410 is still available, as it is CCFL, and is used by pro photographers.
