Using this info, I was able to set my HD 4600 graphics drivers to get 3840 x 2160 at 60 HZ interlaced to drive my new AOC 32" display with the built-in HDMI port in my Lenovo E540. Previously, I was limited to 30 HZ.

Yes, many thanks, another success. Your advice worked for me too, setting up a Custom Resolution. I have a Dell Inspiron 17R SE 7720 made in 2013. The graphics adapters are Intel HD Graphics 4000 and a Geforce GT 650M. With your help I got 2560x1440 (WQHD) on a Dell U2715H and a good quality HDMI cable.
Hi, under the heading "Nvidia GeForce graphics card without Optimus", you say "(despite with Optimus, the HDMI port is directly connected to the GeForce G210M), driver: 313.96". I tried to install the NVIDIA 313.96 driver on my ASUS UL50VT (Win7 32), but it says that it cannot find a compatible graphics card. The standard (native) driver found at the ASUS webpage does not have an option for adding a custom resolution.
I recently bought a Hanns G 1440 27" monitor. With VGA or HDMI, my laptop would only show a max of 1080. I could get 1200 with some fiddling.
With the same laptop, connected to my cheap Korean 30" monitor, I could get 2560 x 1600 with a bog standard VGA cable or HDMI. No issues at all.
My desktop connected to the Yamakasi 30" monitor via HDMI works fine also at 2560 x 1600.
Why do more expensive apparently 1440 or 1600 monitors struggle to give their maximum resolution via HDMI and why do they just not give any resolution over 1080 via VGA, when a cheap Korean Yamakasi monitor can do it just fine???
I had the same problem with AMD Dual Graphics on Asus N56DY and Dell U2515, and could not set resolution to 2560x1440 with HDMI. The problem with AMD HD graphics is that there is a pixel clock limit of 165 MHz for single-link DVI and HDMI, and that doesn't allow higher resolutions over HDMI. There is a patcher for it. After patching and restarting the resolution will be available. Here is the link: http://www.monitortests.com/forum/Thread-AMD-ATI-Pixel-Clock-Patcher
Hey guys, Please excuse my ignorance here. I have a Lenovo Z50 that has a GeForce 820M that according to Lenovo is rated to "Max video resolution: [email protected] (HDMI 1.4a)". Are you guys saying that with this I can still force it to go to 2560x1440 through a custom resolution? I'm considering whether to buy a new 2560x1440 monitor or stay with a standard 1080p. I use this system for work, browsing, Office suite... Thanks all!
