LED SCREEN KNOWLEDGE :
Dont be cheated when you choose LED screen and people tell you 7680HZ refresh rate is better than 3840HZ . We know that for film shooting we use this 7680HZ , but the LED screens for this is customized with high end materials and well designed PCB and together with Novastar A10S PRO card can achieve it . Any other LED Screens in the market with 7680HZ refresh rate ,it is just a figure ,never improve the performance , it is using normal IC and sacrifice the gray scale and color performance to get that figure . Especially those low level LED screens suppliers just want to use 7680HZ as a selling strategy to get customers ,because their product no special feature or value .
For 3840HZ already very high refresh rate for events LED screens and it is camera friendly . A normal IC 7680HZ performance is worse than 3840HZ . For example same IC company ICN2153 IC cost price for 3840HZ rate is expensive than ICN1065S for 7680HZ rate .
How can a 7680HZ refresh rate IC cheaper than a 3840HZ refresh rate ? I guess you got the point .
