I got an Acer XB241H for Christmas, which I've enjoyed. It's 144hz and supports overclocking up to 180, which is advertised on the box. Every time I try to overclock it though (using Nvidia Control Panel), the monitor goes black and only turns on when I exit test mode. I made show that i turned on overclocking on the monitor, but I guess it doesn't work. I can only get to 146hz and anything after that crashes the monitor. Are there any solutions to this? Thanks.
