[測試] U2515H HDMI

A brief report on the newly arrived U2515H

mon: U2515H
cpu: G3258
gpu: G3258 internal
mb: Asus H81M-A
link: Sunon HDMI cable (1.3 rated)
Max. rate: 2560x1440 50 Hz 32 bit color

May be due to driver issue, 2560x1440 60 Hz cannot be set. Intel driver tells that this resolution exceeds max. bandwidth.

Anyway, the mon displays very good. 4K movie is very brilliant.

In win7, font can be set 200 % enlarged. Letter becomes big and clear. It is very comfortable for normal distance view.

you need to use displayport for 1440p 60Hz...

I did a search in Intel forum. It is not related to hardware. All Haswell igpu can do 2560x1440 60Hz via HDMI. It is related to the Intel driver. Intel driver limits the HDMI Max Pixel Clock to 225 M. This bandwidth is slightly less than 2560x1440 60 Hz. Someone can do HDMI 2560x1440 60 Hz under Linux.

Yes, may be I need a DP cable to try again.

according to the manual, you can't do 2560x1440 @60Hz through HDMI port...

P.12

and I believe you can't too run 1440 or 1600p on U2715H and U3014 @60Hz through HDMI...

Page 13 said that 2560x1440 60 Hz needs 251M bandwidth. But Intel driver limits HDMI to 225M bandwidth. It may be the reason.

Anyway, 2560x1440 50 Hz performs good at the moment.

我試過U2713H + Z97 + 4590T(HD 4600)用HDMI可以出2560*1440@60 Hz

I think you are not gamer (intel graphics), cause I would like to know, if 2K mon  run 1080p Game is it clear or not,

why I want to know 2k mon run 1080p game, cause I think my GTX 970 cannot run high quality effects on 2k resolution (low FPS), hope some one can test it or report

I am not a gamer. I am overage.
