FPV tx/rx channel selection

So I'm just starting to dive into the weird and wacky world of FPV. Just wondering if it matters what channel I use and if so, how do I determine the optimum channel.
 
OK thanks. The reason I ask is I can't seem to get a view on my monitor. Pretty sure my TX & RX are just not compatible. Aomway 32 channel diversity reciever and Helistar FT958 40 channel transmitter receiver. Even the frequency charts aren't the same. Transmitter has frequencies A to E with 8 channels each, but receiver has frequencies 1 to 4 with 8 channels. And I've tried different combos with zero results. LOL I'm typing this at work and just noticed that the only frequency that matches is 2/8 on my receiver and B/8 on my transmitter which are both 5866 mhz. Hmmm

That should work, say you're sick and run home hahahahaha.
 
I give up :( I've tried multiple frequencies on the VTX, programmed matching frequencies in the VRX and also used the auto search feature each time. I'm bench testing this and tried multiple locations. RX is diversity and I've tried 1, 2 and both. Tried different antennas. RX is fully charged and I've tried powering TX with both fully charged 2S and 3S batteries. I know I'm receiving some kind of signal because monitor screen shows a little bit of change the odd time, but just not getting an image. I guess the only thing left is to try a different TX. TX is Helistar and RX is Aomway and maybe they just don't play well together. Funny thing is when I got the monitor on Saturday, I did have a perfect image for just a bit.

I've had Txs come and end up being listed as the wrong band hahahaha Might get one 8ch and one 32ch, or triple check that you will have overlapping frequencies.
