Swansea City's Marvin Emnes and Southampton's Sam Gallagher were in top form for Blackburn with Watford defender Tommie Hoban playing a full 90 and West Ham United attacking midfielder Martin Samuelsen coming on late.
In the opening minute of the second half, Emnes teed up Ben Marshall who produced a beautiful left-footed curler to make it 3-1 prior to Ward's second for the Millers in the 83rd minute.
But Gallagher wrapped it up in injury time when he simply tapped home his third league goal of the season after being unselfishly set up by Emnes.
Check out the highlights below, courtesy of Blackburn's official YouTube channel:
Rovers boss Owen Coyle spoke glowingly of loan pair Emnes and Gallagher after the game.
He told Radio Rovers: "I thought Emnes and Gallagher were outstanding.
"They really showed their quality, the two of them together were terrific.
“They gave us pace, they gave us strength, and today they gave us goals.
"I thought it was a wonderful team performance and the strikers were pivotal to how we played and long may that continue."
On the other side of the coin, Brown was clearly frustrated with the result:
