Color Calibration Software and Advice

I just bought an iDisplay Pro Plus and looking to buy a new monitor. I've been using DisplayCal to do my calibration for years, but lately my calibrations look terrible. Hence me buying a new colorimeter. I'm trying to decide if I should continue using DisplayCal or switch to the iProfiler. Does anyone have any advice or opinions on how to calibrate.

I am a small video production company, I do mostly web stuff for clients, but on occasion will do a film or something for TV. But I want a solid monitor calibration that can handle my day to day life. If I need to do special adjustments for film or tv things later, I can.

Also, do people do special luts that they use in Resolve? I've always just calibrated my monitor and left it at that. I know DisplayCal can create luts for Resolve, but never tried it. Should I be doing that?

And do you have any general calibration advice? I feel like I read so much info from so many places, I almost feel more lost on what I should be doing.

What monitor are you using?

Sorry, I am using a Dell U2410, but I am also looking to upgrade my monitor very soon. So I wasn't sure if I should include it in the post.

I'm using DisplayCalc with a SpyderX Elite calibration device. I do calibrate my monitors every 2-3 months (probably should do it more). It does work well for me and I'm happy with it. I was looking at the x-rite i1 display pro but the difference I see gaining from the i1 is its software generating better profile when compare to the Spyder. Since I am the device with the DisplayCalc software, I found that difference to be irrelevant (at least for the time being).

I also generate a LUT for Resolve using DisplayCalc which I use on the reference monitor.

Thank you, it fits for me, I even build a DisplayCalc LUT for Resolve I am using on the comparison monitor.
