DVI vs HDMI vs DP 2019

I've almost completed a new gaming/media rig, and I'd like to get a EVGA 2070 XC ultra gaming (I hate the names all these cards and mobo's, u never really know what's what). And I just noticed it only has HDMI 2.0 and DP. My qnix 27" 1440p only has working HDMI1.4 and VGA, DVI-I (duallink) stopped working and this monitor is a few years old, so I'll probably upgrade it too.

I have no idea what monitor to get next year, the prices of 1440p 144Hz and 4k 60Hz are as horrible as NV and intel, plus NV g-sync monitors are milking everyone as well as probably screwing over people if they have to use an AMD card at some point. No way am I spending +800CAD on a monitor (I say now). No wonder people just get xbox/ps, so much cheaper/simpler.

I know HDMI 2.0 can do 4k 60Hz, I watched this

What's the best GPU output options going forward ? And how much does converting between formats with cables/adapters make a difference w.r.t. lag in games ?

There's different versions of HDMI/DisplayPort and different versions can do different resolutions at different refresh rates. There is no image quality difference between them as long as you're comparing good quality cables vs good quality cables and are staying within spec.

Use whatever can support your monitors refresh rate and resolution. DisplayPort 2.0/1.4/1.3 or HDMI 2.0 ideally.

Image quality on adapters depends on the adapter and what you're converting to/from.

Don't use VGA in 2018 unless you're hooking up a CRT. It and molex need to die already.

and it's still 2018 btw not 2019

Hi,
G-Sync monitors only have display ports so maybe that will narrow the question down a little
Plenty of them for 250. & upwards.
144Hz monitors will usually have either all three connections dvi-hdmi-dp we're talking 3d vision...
DVI being the most reliable of the three

I didn't even realize DVI->VGA was holding me back, so I've switched to the HDMI port on GPU/monitor.

Yup so go for latest HDMI/DP, DVI last option

It and the four pin AMP, now TE Connectivity MATE-N-LOK 1-480424-0 disk drive power connector need to die already. --ftfy.

While Molex makes (and has made) a lot of connectors, most of what you see used today in PCs and their peripherals are only available today via companies like TE/AMP, JST, and a whole slew of cheap you-know-who wannabes.

Since we're being anal...

most likely not a problem nowadays but make sure the display supports HDMI-PC (even the manual explicitly stated HDMI-PC not supported)
I have a monitor that has HDMI but doesn't support HDMI-PC and it has overscan issues and image quality issues when hooked up HDMI.
Single monitor setups, use whatever supports the highest refresh rate.
Multi monitor, windows 10 and displayport have issues regarding icon and window placement. HDMI doesn't have this problem. Freesync seems to play nicer with displayport than HDMI. (generally it should be problem free though)
After trying all 3 for quite sometime, DVI ended up having the least amount of problems but has the most limited functionality.

Displayport is for monitors, HDMI is typically for TVs and has a royalty attached to it.


If you intend to use adaptive sync such as GSync or Free-sync, Displayport generally is the best. Displayport 1.2 can already support 4K 60Hz , version 1.3 can do 4K 120Hz. HDMI 1.4 can only do 4K 30Hz ; HDMI 2.0 supports 4K 60Hz.
