A little more detail would help here.
Native resolution is the big factor here, not screen size. Using a 32" TV with 1080p output but a native panel resolution of 720p will give drastically inferior results to a proper 2560x1440 display and will result in the blurry interlaced text you are experiencing.
If your 32" display is actually a repurposed TV, get shot of it and get a proper monitor on the go. As mentioned by many, QHD (2560x1440) is the sweet spot for most.
Personally I use a 34" ultra wide alongside a 27" in portrait with the secondary display bi-wired to both the PC and Mac.
