What is the maximum display supported by an Intel HD Graphics 4000 chipset on a Lenovo t430? I am considering buying a 1920x1200 monitor and wanted to make sure my graphics could support said resolution first.
Intel HD Graphics 4000 supports resolution up to 1920×1200 through HDMI and 2560×1600 through DisplayPort. You should be safe.
Your Lenovo T430 has Mini DisplayPort connector on left side, so you can even reach for 30" or 32" displays with 2560×1600 (like Dell UltraSharp series).
I'm writing this answer from Lenovo with HD Graphics 4000 connected through HDMI to 1920×1200px LCD – so yeah, it definitely works.
It seems to be impossible to find specs document for HD 4000 directly at the Intel site (it was there before), but it is possible to find this information on many 3rd-party sites. Or check specifications of your laptop, it could be there. This is the best what can be found at Intel but specs are only partial there.
Additional note: 16:10 screen ratio is a good choice for productivity, I definitely recommend it over 16:9.
For a Lenovo T430 Maximum external resolution:
- 2560x1600@60Hz (DisplayPort via optional Mini DP cable)
- 1920x1200@60Hz (single-link DVI-I via optional Mini DP cable)
- 2048x1536@75Hz (VGA)
Is 3840x2160@25hz (with reduced blanking).
xrandr --newmode "3840x2160x24.99" 218.500000 3840 3888 3920 4000 2160 2163 2167 2186 +HSync -VSync xrandr --addmode HDMI1 "3840x2160x24.99"
Then apply this setting with your favorite "Display Settings" utility.
I just bought an UHD 4K screen in 27" (a Benq2711U) despite the limitation resolution standard : officially it's not possible to have an external monitor in resolution of 3840x2160 with a thinkpad x230 or T430 due to "Intel HD Graphics 4000" limitations.
But I like to try myself ... and with a active adapter dvi to hdmi & a custom mode at 30 Mhz it's possible ! Imagine an old laptop of 2012 with this wonderful display resolution :)
My configuration, a Thinkpad x230 with a docking station ThinkPad UltraBase Series 3
DisplayPort 1.2 to Active HDMI 4K (UHD) Adapter or if you don't use a docking station, this adapter also works: : Mini DisplayPort 1.2 to Active HDMI 4K (UHD) Adapter
At your own risk, create a custom mode : 3840x2160 @30mhz:
In MsWindows CustomModeApp.exe from intel should be very helpful: install the lastest driver, & launch custommodeapp.exe with the help of windows shortcut: Win + R, in the application, select relevant screen, create resolution with 3840x2160 @30mhz & CVT-RB, disconnect, reconnect & change resolution.
In Linux, call
xrandr --newmode $(cvt 3840 2160 30|tail -1| perl -pe 's/^Modeline\ //') xrandr --addmode $(cvt 3840 2160 30|tail -1| cut -d ' ' -f2)
Think to cvt -r (= with reduced blanking) if it's better for you, & if you prefer to apply this display with command line, think to use && sleep 5 && "return to your own safe default display" ...
I have been using a Lenovo T430 for a very long period. I recently bought a new 4K monitor (Samsung U28E590) and it delivers me a 2560x1600@60Hz resolution with its Mini Display Port via Mini DP cable which I bought separately.
Before buying this cable I used an HDMI cable to connect the laptop with this monitor and the supported maximum resolution was 1920×1080.
It at least has 3840*2160 at 30 Hz. (Confirmed it by using xrandr)
