More than two screens on intel graphics?

#1 Post by tecmes » Mon Aug 02, 2021 9:37 am

It seems that intel integrated graphics (older models??) can't extend the desktop on more than one screen (i.e. you can't have three+ screens). I just realized that now...
My newer T560 with Win10 can do it. So...
Is that an issue with older intel graphics? With Win7?
Typer: X61s. Drawer: X31. Office: T560. First crush: X20. Nostalgia: SXGA+ 770 (one busted power card too many)
Gripe: why nobody makes recessed laptop power jacks?

Older Intel graphics.

Already on Ivy Bridge (**30 generation) it sorta became possible to get 3 screens with Intel GPU, but only under specific conditions. The conditions got more relaxed with subsequent generations.

You can get many screens working with USB-to-DVI or USB-to-HDMI displaylink adapters.

I've gotten as many as 5 screens to work with my X220/X250/T480s using 2 displaylink adapters

The X61 is dead... long live the X61

Well, W7 was never that great with multiple screens. You can get 3 but usually one has to be the ThinkPad's display. It's easier with an advanced dock (T61 / T500 era) or the newer dock for the T410 / T510 / W510 and later models.
