Macbook Pro Early 2011 (Intel HD3000 GPU) , can i run an external monitor @ 75HZ

[Aleks Ippolito]

Hi


I'm thinking to buy an external monitor that runs full HD 1980x1020 @75hz refresh rate.


Can my GPU work with that refresh rate ? if not , can i still run @60hz with no issues ?


Many Thanks

Tech Specs say it supports 2560x1600 display (assuming 60Hz).

That means it should be able to do 1920x1080 144Hz 8 bpc (347 MHz) or 120Hz 10 bpc (286 MHz) so 75Hz should work.
For 8 bpc, the limits are: 360 MHz for DisplayPort 1.1, 340 MHz for HDMI 1.4, 330 MHz for Dual Link DVI.
For 10 bpc, the limits are: 288 MHz for DisplayPort 1.1, 272 MHz for HDMI 1.4, 264 MHz for Dual Link DVI.

Have you disabled the AMD graphics? If so you're out of luck for using external monitors.

@hftvhftv I haven’t got any AMD applications running on my macbook.. and i am already running an external monitor.. so i m not sure what you mean..

@joevt Not sure what bcp are... anyway , as long as i am able to make the screen work , i don’t really mind wether it runs @60hz or @75hz

so..my definite question is :

will the 75hz monitor work?

thanks

It'll probably work. Is it a 13" model?

Yes it s a 13” model

Not sure what bcp are

bpc = bits per component. Three components: Red Green Blue, or Y, Cb, Cr.
So 8 bpc = 24 bpp (bits per pixel)
10 bpc = 30 bpp.
12 bpc = 36 bpp (Mac OS supports this but I don't know a utility to select it - there's also no utility to switch between RGB and YCbCr or from 4:4:4 to 4:2:2 or 4:2:0)
In Windows, you can also select 6, 8, 10, 12, or 16 bpc, switch between RGB and YCbCr, switch between 4:4:4 and4:2:2 and 4:2:0.
