SE2719HR, Lenovo ThinkPad T470s, can't detect HDMI
Hi,
I use a Dell monitor (unknown type) everyday with my Lenovo ThinkPad T470s for work. I decided to buy another Dell monitor for when I study at home.. using my Lenovo laptop. I can't seem to get the Dell SE 2719HR monitor to connect.
- I have tried "Hard" reset of the monitor
- I have tried the "Run the monitor Reset, Self-Test, Built-in Diagnostic" which came back clear
- I have tried connecting the laptop with the NEW HDMI cable provided with a different monitor and it worked!
- I have tried connecting the NEW monitor with the new HDMI cable to a different computer, which also worked!
Essentially they both work...they're just not communicating to each other.
When i connect the HDMI cable from my new monitor to my Lenovo ThinkPad, the Dell monitor remains black, as if it was turned off. HOWEVER when i go to display settings, the laptop picks up the monitor and can identify two screens but can't detect two.
I'm not too bad with tech so i have had quite a play around etc. but i cant seem to fix this one
your help would be appreciated!
thank you!
Vanessa

@VanessaVanessa Do you have admin access to your work system so that you can update the BIOS and graphics drivers? If so, I’d try that, or otherwise ask if your IT Department might be willing to help you do that.
However, you might want to consider a different display anyway. That display appears to be a 27” 1080p model. 1080p resolution is more commonly used on 24” displays, and even there the resulting pixel density is lower than the Windows “reference” of 96 pixels per pinch. Stretching that same resolution out to 27” will only drop it further, which will lead to a grainier image that would be especially noticeable on text — and your also end up with a larger 27” display without actually having more space to work with. That’s why the more common resolution for 27” displays is QHD/1440p (2560x1440), which is a bit HIGHER than Windows reference pixel density for a sharper image AND gives you a lot more workspace. I use that type of display and I’ve noticed that in Word and Acrobat, it’s possible to display two 8.5x11 pages side-by-side in their entirety (margins and all), in either portrait or landscape orientation, at full print size, i.e. matching the size of a physical sheet of paper held up to the display, with room still left over for Word/Acrobat’s menus and such.
A 27” 1080p display makes sense for a kiosk display meant to be viewed from a distance where size and low cost matter more than sharpness, and it would also make sense for people with impaired eyesight where they specifically WANT things to be bigger than normal rather than using the extra size for more workspace — and I guess it would make sense for media-centric uses — but not so much for a work display.
