Since I bought it, my Dell Inspiron 15 (7537, with Nvidea GeForce GT750M graphics) was plugged into an old 1920x1200 24" monitor... until, recently, the (very-old) monitor spectacularly died - with a bang. The old set-up was good.
I've been looking for a replacement external monitor. I want to run it to extend the laptop display (as I did with the old 1920x1200 display) but I am finding compatibility information very hard to come by.
Over the weekend, I managed to hook the laptop up to a 4K TV... it would drive it, but not simultaneously with the display in the laptop... and the frame rate when playing back a 1080p video was shockingly bad. These glitches have persuaded me that I should not try to use a 4K monitor for everyday work.
These days, large, new 1920x1200 displays are rare... I am trying to establish whether a WQHD (2560x1440) display, when connected to the Dell over HDMI, would provide me with a sensible refresh rate... while extending the display in the laptop.
Does anyone know if (or how I can find out if) my laptop will drive a WQHD display "properly" over HDMI, while also driving the internal 1080p panel?

to get the resolutions you want. The specifications are very helpful.
