RazerBLade wont connect to new sony tv

I dont understand why its not working. The tv works perfectly fine i can cast any other device on it. i can even connect my razerBlade via BT but only as "other divice" its like my laptop is not seeing the tv as a monitor. so when im looking to cast\\project my screen (even if im connect to it) it doesnt show up as a display to conect to. im on the same wifi to, i even tryed to direct connect to it but it makes no difference. also it was working with my old tv
