Hi nit sunlight readable 24" monitor

[r3g]

Does anyone have any recommendations for a 24" monitor for outdoor (dry) use with a high nit (brightness) so I can see what's on the screen when the sun is out My bog standard Dell is not cutting it, even with the brightness and contrast at 100%. Not sure what the standard nit is, but some light research seems to indicate pretty much all the mainstream stuff tops out around 300 nit.

Annoyingly, every site that flogs monitor does not mention the nit.

Thanks
