Choose a Monitor?

[eninja]

I don't understand the concept of dedicated video card.

lets say my laptop got dedicated video card, does this feature only work for my built in monitor? or this feature will also be extended to the external monitor?
if yes, will I stress the video card, if the higher the resolution of my external monitor connected in my hdmi port?

what if I add video port thru usb? will I be using the video card of laptop?

architecture wise, how is the block diagram connection of video card -> built in screen -> external monitor with reference to Video Signal?

I've been asking this at the back of my head ever since.

Hope someone can shed a light.

UHD for better for sure.

You can get the Dell UP2414Q: wide gamut, uniformity compensation, high bit internal LUT, direct current driven LED backlight, UHD, IPS for $700-something now.

27'' is fine if you have the room, but it doesn't give you any better res - in fact lower - than the 24".

I saw that as a plus, at the moment, given all the complaints about scaling and how small the fonts and icons are in Photoshop and Lightroom on a UHD monitor. I don't have CC, so I don't have that experimental 200% font feature that they added.

Lightroom scales the entire UI perfectly on UHD.
Photoshop CS6 and better do too on the MAC.
Photoshop CC does on Windows.
