For most users, the i1Pro2 and the i1Display Pro are going to be the optimal choices.
For the i1Pro 2 (if just getting the i1Basic 2 which is same device but fewer other elements), that may get a bit costly as they currently sell for $1200-1350 now many places. This is a spectrophotometer that reads in 10nm wavelengths the color spectrum, but can be put in a higher detail mode which is around 3.5nm wavelengths. This will be fine for most users, but if you absolutely need more detail, you would need a CR-250 for about $6000 (IIRC), a Jeti for around $9000+, or even more expensive reference equipment. You can also pick up a used i1Pro 2 on ebay if needed.
For the i1Display Pro, you will want to pick up a 2018 or newer model OEM variant which can read to 2000 nits. This is a colorimeter, not a spectroradiometer/spectrophotometer. These are better at luminance readings and use tri-stimulus filters that more approximate how the human eye sees color. This can be purchased for $200-300 usually.
For more information on the two recommended color analyzers, you can go to X-rites' web page or review Ted's page discussing both of those products. https://www.displaycalibrations.com/...ions_info.html
Another option, instead of buying the spectrophotometer is to contact a local calibrator with reference grade equipment. He or she will be able to create a CCSS spectral profile of the display with the reference spectrometer and can create a colorimeter correction matrix compared to a reference colorimeter like a Klein K10-A. With the spectral profile and the colorimeter correction matrix to use with your i1Display Pro, you will be able to do an excellent profile and calibration of your display. You will need a CCSS for each display you plan to calibrate, including monitors for your computers and laptops, so you may want to count up what you want them to do a CCSS for and work out the pricing ahead of time.
Then there is the matter of patterns. Some programs have an in-built pattern generator. But, due to the complexities of where errors can occur, you may want, at minimum, to get something like Ted's disc or R. Masciola's patterns to have something to compare the pattern generator to, as missing a setting in Nvidia's control panel or MadVR or any of the other options there are could introduce errors, before discussing the problems with HDMI port inaccuracies, etc. For Nvidia's control panel, there are two places you need to go to set the range for output. First, go to Video>Adjust video color settings, then switch to with Nvidia settings, go to the advanced tab, then set that to Full (0-255).
The Second one is under Display>Change Resolution. Here is where you should select the output color format (RGB or YCbCr) and the Output Dynamic Range (full or limited, which is the same as 0-255 or 16-235, respectively). If using MadVR and Nvidia graphics card, in addition to what I just told you, you will also have to set the MadVR dynamic range as well.
Because of this, having patterns already checked is needed to make sure you don't miss set those other settings.
If you really want to go big, you can buy a pattern generator. The better ones will set you back $1000-2600, depending on mfrs., models, and features.
