| From: Giles Orr <gilesorr@gmail.com> | I assume you mean this: | | http://www.bestbuy.ca/en-CA/product/philips-philips-40-4k-uhd-60hz-3ms-gtg-v... Thanks for posting the link. The ad I got said that this was a two-deay sale. I think that today is the last day. | Is there any practical way to drive this from a Linux-based laptop | that doesn't currently have an appropriate video card / output? (I | don't consider "buy a new computer" to be a helpful answer: I'll be | ready to do that in about 18 months. But I'll understand if the | correct answer is "no." :-) I'm OK with 30Hz. I better be, since that's what I've got. Your ASUS-ZenBook-UX305CA-UHM4T ultrabook can drive my monitor (UltraHD at 30Hz, through HDMI). I know because I tested the same model here. I just checked again (Fedora 23). It uses the integrated GPU of the Intel Core m3-6y30. I just now tested my Lenovo Yog 2 pro, and it could also do UltraHD at 30Hz through HDMI. That has a two-generations-older intel processor's integrated GPU (i5-4200u). It is kind of neat having a 3200x1800 notebook display PLUS a 3840x2160 monitor at the same time. On the other hand, appropirate scaling for the two displays is quite different (13.3" vs 39" for not-too-different pixel counts). I haven't tried to scale two displays on one desktop differently. Summary: I consider 30Hz "practical", so I would answer your question "yes".
