Can I ask what make is your monitor? I had the same issue whilst others hadn't. I tried some things that didn't work for me. The only thing I could think is the monitor mine is AOCI've raced 12h of Sebring at SRC, and it was perfectly fine, but here I can't see anything past 150 meters. Headlight don't light up anything and I think that would be a big issue come on race day.
