Maximum resolution with U2713HM and HD 4400 via HDMI

post #1 of 3
Thread Starter 
Hello all,

I know there have been many posts about it, but I couldn't find an answer for this specifically.

Got a laptop with HDMI 1.4 (though as I understood U2713HM is HDMI 1.3, can someone confirm?).
Laptop model is: S7-392 with a monitor of 2560x1440.

Connecting it via HDMI to U2713HM and trying to add a custom resolution of 2560x1440@55hz with CVT-RB with no success (though in a guide it says that it should work). 2560x1440@30hz - works, but I don't like the flickering.
Tried 2048x1152@50hz - works, if I set 55hz it already stops working.
2304x1140 doesn't work with any hz above 30hz at all.

Cloning or extending or showing only on the external monitor doens't change anything.

1. Can someone tell me what is the maximum resolution@hz they managed to achieve?
2. Any idea what to try to achieve the 2560x1440@55hz?

Thanks

You can probably do 2560x1440@42 hz. However, the Intel driver might not let you do that. The U2713hm itself will not let you run at 2560x1440 @60hz via HDMI1.4.

Could you clarify which Acer Ultrabook version you have?

It may have a mini-Displayport output.


You may be able to get full 2560x1440 resolution using a Mini-DisplayPort to DisplayPort Cable.

For some reason Laptop hardware board makers do not allow 2560x1440 even though they are using HDMI 1.4 without having to mess with the refresh rate.
