Overclocking L24q-10

[Gloredex]

So I got an L24q-10 (1440p 60hz) yesterday and have been trying to overclock it, but something weird seems to happen once I try to go over 66hz; it will still work, up to 73hz to be exact, but a message pops up on the screen saying 'Input Signal Out Of Range', and there doesn't seem to be a way to remove it, it's just there on the screen. I've even tested it on sites like testufo.com and it still works perfectly at framerates above 66 but for some reason that message seems to still pop up on the screen. I was also wondering if it could have something to do with the GPU, since I'm about to upgrade from my current one (Radeon R9 380 4GB) to probably an RTX 2070 or RX 5700XT, so maybe that could that change potentially affect the overclocking? Becuase right now the AMD Radeon display settings doesn't even let me try setting the resolution higher than 73hz, because it says that the monitor 'doesn't support it', which is weird since it actually doesn't 'support' any framerates above 60.

 

Picture of the message that pops up when trying to configure refresh rate to over 66hz:

 

Any advice is appreciated.

Basically it is telling you the overclock is too high. Reduce it.

That means the max you can overclock that monitor is to 66hz. Anything higher the overclock is unstable.
