Thanks for that, only problem is that the monitors dont have a minus sign on them. Their model number is E151FPb. Thanks,

in the FAQ - Burnin Mode left on from the factory

I've seen a few others with the same problem - those instructions don't work for all monitors. ChrisM had a few suggestions here.

mc_tintin,

* Press the Menu button to enter the OSD (On Screen Display)
* Choose Factory Reset
* Choose All Settings

Chris,
I've tried resetting the monitor to the factory default settings but it still does colour cycle. Only seems to do it when the monitor isn't receiving any signal.

Thanks,

mc_tintin,
