OK, thx!

I plugged 4 monitors and 4 GPUs working well!

Dummy VGA is a good solution.

3 work properly. 1+2+3, 1+2+4, etc. 4 does not work.

I put 4 R4770 to one box and they were joined by CF. Each card is working correctly in other boxes. I see 4 GPU in CCC and in Boinc.

When I give "<count>2</count>" two cards work quickly and correctly:

Unfortunately, when I give "<count>1</count>" everything works terribly slow. CPU load at 100%, GPU load very low.
