[SOLVED] How should I calculate the possible supported resolutions of my GPU?

Hey everyone!

I would love to update my current setup and buy an ultra-wide monitor, main purpose would be work: I am a software engineer and I spend most of my time either on Visual Studio Code or in GitHub reviewing someone's code.

I narrowed down my options either to:

1) Samsung C43J890DKU - (43°) 3840 x 1200

2) Samsung LS49A950UIUXEN - (49°) 5120 x 1440

I'd love to make sure that my purchase would also work for my private laptop which is a MacBook Pro mid-2014 (Intel 2.6 Ghz I5-4278U). I did some investigation and the internal GPU (Iris 5100) seems to support up to 3200x2000@60Hz via DP and 3280x2000@60Hz via HDMI.

Now... the supported width is clearly less than even the 43° inches but I was wondering (and this might sound incredibly dumb), is it that I should consider? or the multiplication of 3200*2000 to get the total number of pixels? because in that case the 43 inches should work. I mean all of that at 60Hz, because less than that I am afraid it will not look smooth at all.

Thanks!
 
The size of a monitor in inches is irrelevant.

What matters is the capability of your laptop's graphics adapter when connecting to an external monitor.

For an older gen laptop, that may be a problem.
You will get the size and real estate you want, but you may have to run at less resolution than what the monitor is capable of.

Once you have the monitor, personalization in windows should give you the possible options and associated refresh rates tha are available.

Thanks for your replies!

@geofelt
So essentially what you are saying is that, even if it runs at 60Hz, it might still feel sluggish?

@Glenwing
Thanks for sharing this calculator, from my understanding:

3840 × 1200 (16∶5 ratio) at 60 Hz
8 bpc (24 bit/px) RGB color
Uncompressed
CVT timing format

Data Rate Required: 9.29 Gbit/s

Should fit well within what the display port on my Mac allows, am I calculating it right?

(The 5120x1440 also fits with 15Gbit/s but it's a way closer call).

Yes
