Images looks soft in Lightroom

When I view or edit in Lightroom (latest version) images don’t look that sharp (24” Dell Monitor) and yet when viewed in Photoshop they look pin sharp. I’m wondering if there is something Lightroom calibration setting I may have wrong? Can anyone help please.
Also, I try not to crop but unfortunately, sometimes I don’t have a choice? I know cropping can cause the image to lose some quality but a friend said rather than crop it’s better to use the scale slider on Transform.
Anyone know which would be the best option to give best quality?
Look forward for any advice.

I use RAW for landscapes and Portraits and I use both for sport, generally jpg as I can take between 1500-2000 images. If it's a really cloudy, rainy or a particular rider I want to take I use both RAW and jpg. Checked the Lightroom preference and the Smart Previews is not ticked. I edit in Lightroom and then if needed open in PS via 'Open as Smart Object in PS'
