Intel HD 4000 HDMI 2560x1440 resolution???

[idata]

Hi,

I recently bought ASUS Zenbook Prime UX31A with "Intel GMA HD 4000 ".

Is it possible to get a resolution of 2560x1400 on my external DELL monitor? (Monitor supports the resolution)

I tried in the Intel Graphicoptions to add a manual resolution, but I get an error

"The user defined resolution excesses the maximum bandwith capacity" (translated from german...)

Maybe u guys have a solution.

Thanks

In case you get here by a post, I'd like to share some factual information on the matter:

1) You can set whatever resolution and refresh rate you desire as long as:

1. Your monitor supports it
2. Your cable supports it (e.g. an HDMI 1.2 cable on an HDMI 1.3 port is limited to HDMI 1.2 bandwidth)
3. Your output type supports the bandwidth required (http://www.kramerelectronics.com/support/bwcalculator.asp use this web page to check)
   1. HDMI 1.0-1.2 = 4.96Gbps
   2. HDMI 1.3-1.4 = 10.2Gbps (max usually advertised as 2560x1600@60hz, but can just do 3840x1440@60hz)
   3. HDMI 2.0 = 18Gbps (max 3840x2160@60hz:10-bit colour)
   4. DVI-D = 3.96Gbps (max 1920x1200@60hz)
   5. DVI-D Dual-Link (2x DVI-D, one cable) = 7.92Gbps (3.96Gbps x 2) (max usually advertised as 2560x1600@60hz)
   6. DisplayPort 1.0-1.1 = 8.64Gbps (max usually advertised as 2560x1600@60hz)
   7. DisplayPort 1.2 = 17.28 Gbit/s (max 3840x2160@60hz:10-bit colour)
   8. DisplayPort 1.3 = 25.92Gbit/s (etc)

2) You can't set a custom resolution in Windows, because Intel's software has a critical bug. A bug that's been there for, literally, YEARS.

• 4 years later from this initial post, and Intel still haven't fixed it as of February 2016.
• Maybe Bryce@Intel might update /thread/78158?start=0&tstart=0 this thread with some good news about bug # 9024844 (Raised in August 2015)

3) How to enable custom resolutions in Ubuntu (linux):

1. Find out which output name represents the port you want to add a custom resolution for:xrandr (mine was listed as HDMI1)
2. Generate a mode configuration string with cvt or similar:cvt -r 2560 1440 60 (application, options, pixels wide, pixels high, refresh rate) 
3. Copy the second line of text returned from the program, but without the word ModeLine:ModeLine "2560x1440R" 241.50 2560 2608 2640 2720 1440 1443 1448 1481 +hsync -vsync
4. Run this command (with your own text of course)xrandr --newmode "2560x1440R" 241.50 2560 2608 2640 2720 1440 1443 1448 1481 +hsync -vsync
5. Run this command (use your own values)xrandr --addmode HDMI1 "2560x1440R"
6. Activate the new monitor mode! (use your own values)xrandr --output HDMI1 --mode 2560x1440R
7. Congrats! You get what thousands and thousands of Windows users haven't been allowed to have for over 5 years! Hooray for privileges!
