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: 1920x1200@60Hz (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!
This was hugely helpful! Lots of forums talked about how maybe it'll work, maybe it won't, who knows? But this website actually answered the question! That intel driver thing did the trick. It took some fiddling, trying different settings and (especially) unplugging and replugging the HDMI cable, but it eventually worked. The Intel driver user interface is really not very well written, but whatever; it can be made to function eventually, with enough patience. It's frustrating that this was necessary when connecting a Dell laptop to a Dell monitor, but now that problem is finally solved. Many thanks!
Thank you very much in deed for this article. I recently bought a new 27'' high res monitor (2560x1440), based on a positive review conducted by a German web side famous for its monitor tests (www.prad.de). It is the iiyama ProLite XB2779QS-S1. I connected it to my 2010 Sony Vaio VPC-F11M1E. Since my Vaio notebook only features a HDMI (and a VGA) port I decided to connect it via the DVI cable (which came along with the monitor) with an adapter to HDMI. However my displayable resolution was limited to HDMI standard resolutions only (e.g. 1080p). When I applied the steps described above I was able to exploit the available native monitor high res! I had to set "CVT reduced blanking" instead of "automatic". The picture is sharp and clear!
I did as described with BENQ BL 2710PT and DELL Latitude E4630 but after 10-15 sec the screen started blinking and failed in black. This Dell notebook has only VGA and HDMI. Contacted Dell support and they told this notebook has HDMI 1.2 which doesn't support 2560x1440, only starting with 1.4 version according to them. But advised a solution - the doc station. I bought a used one (10 times less expensive than a new device) and connected via the display port normally. Hope this might be helpful for someone.
Thanks so much for this article. Having had the issue of only getting 1920 x 1080 as an option I thought I'd wasted my money buying an expensive high res monitor. I followed your instructions and it's all working perfectly now at 2560 x 1440. As many others have said. You've made my day!!!
Awesome! This actually got me up to 2450x1600 progressive-scan 60Hz CVT-RB on my HP laptop with an Intel HD Graphics 4600 controller! (It also has an Nvidia 840M discrete GPU but I don't think that matters because the video outputs are both hooked up to the Intel controller--you can see that in the Nvidia control panel's PhysX tab).
