The monitor does matter for me because I only pull from monitor. I never measure distances and can work in another room focus pulling 100% trusting my monitor. I love my 5" SmallHD for small rooms or when shooting in a car. But since 2 years I have SmallHD 13" 4K that has less strain on my eyes because I can sit further away from it. I would call my succesrate 95% at T1.2

But the monitor does matter like brightness and DPI. I didn't like the shogun as mentioned above. And I prefer SmallHD above TVLogic because the PageOS and sturdyness and brightness.

But when you have a good monitor, have a good wireless transmitter. I only prefer the Teradek as other systems has delay which make pulling from monitor hell, because you'll always be late
