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).
I was going to give up; but a further attempt remained: to try the conversion DVI (monitor) to HDMI (notebook). Truly, this allowed me to (Selected the Display) set again the 2560x1400 32bit 30p Hz CVT through the INTEL function above (last update here: http://downloadmirror.intel.com/23885/a08/win64_153322.zip) Note that this setting was apparently rejected, but after closing and opening again (mouse right-click on the desktop) this new option was visible in the Custom Resolution list. So far, going to the Display Properties I could see not only, near the 1920x1080, the 2560x1400 for the Dell "U2713HM (Digital)", but even this time it was set as (Recommended). Bingo! Don't warry if on your click to Apply, the sistem hangs again. Be patient, on restart it should be all right, perfectly working (or at least still adjustable): to me, no icon displaced now and the hibernation is immediate and fully functional. If you use Virtualbox, don't forget to run-update the Extension_Pack thereafter.
I could obtain the visisility 2560x1440, 30 with a Dell UltraSharp U2713HM on NVIDIA 630M (notebook TOSHIBA Satellite 875-P, Windows8) after several OS' hangs (even with the monitor off) and re-boot, making the setting accepted by the INTEL Graphic Options/Custom Resolution, and retrying to set the display properties after booting.
BUT I meet repeated desktop icons displacements and above all it seems impossible to recover any hibernation (that I must use daily). The ibernating process is very slow, and on restart it ends into a black window, no mouse or keyboard working; must power off.
Firstly may I thank you for writing such an excellent and comprehensive article. This really helped me to resolve the problem. Much communication with the help desks of Toshiba, Samsung and Intel failed to resolve the resolution problem but your article did so again thank you. To the specifics: I have a Toshiba Portege Z930 laptop running Windows 7 professional. I have this linked to a Toshiba tower dock (which I have to say I am very disappointed with). I purchased a new Samsung S27B970D ultrahigh definition LED monitor with a native resolution of 2560x1440. I was completely unable to get the remote monitor to work at this resolution. It would not go beyond the native resolution for the laptop of 1920 x 1200. After reading your article I found it impossible to increase the resolution until I bypassed the Toshiba dock and took the HDMI cable straight from the monitor to the laptop computer. I was then able to achieve a resolution of 2560 x 1440 at 55 Hz. I also discovered that I needed to change the refresh rate to 55 Hz in the summary Intel graphics and media control panel. As you suggested I also adjusted the timing standard to CVT-RB. Success!!! Photographs and YouTube videos look fantastic
