Picked up a ASUS VG248QE Gaming Monitor. Wanted to use this will my Xbox One as well.

Xbox One is just running HDMI output. Trying to get 144hz or 120hz, chart says that this only works with DVI-D. If I were to use a HDMI to DVI-D adapter would I be able to get the 144hz or 120hz refresh rate? Would HDMI on 1 end stop this? (Not sure is it matters but Xbox One ship with HDMI cable that works with 4k as well)

If the adapter will work then what is the best brand of adapters to use for high quality?

Thanks for any help on this.

you wouldnt be able to use the adapter with xbox-one due to the coding of the hdmi port. Must be hdmi to hdmi unless you buy a special adapter, and to my knowledge these are very hit and miss. Using hdmi you will be able to make use of the 120hz, but at the same time, the xbox one only runs at 60 fps, and for a gaming monitor, it won't make use of anything more than 60hz.

The only reason 120hz is good for consoles is for tv applications where the refresh rate is smoothed out (makes things look more fluid)

hdmi can output at 120hz at 1080p however, so you'd be fine with the 120hz monitor

HDMI versions up to 1.2 support the same data throughput as single link DVI-D.
A HDMI to DVI or DVI to HDMI adapter is converting to or from single link DVI-D, as the video signal for these two is identical and it is just the adapter that is required (HDMI can carry audio, but this is lost with an adapter).
This is sufficient for 1920x1080 (or 1080p) at 60Hz.

The monitor requires dual link DVI-D or display port for 120 Hz or 144 Hz.
These standards include support for higher resolutions and refresh rates.
Technically HDMI 1.3 or higher has the bandwidth required, but I'm not sure that refresh rates over 75 Hz are part of the HDMI standard.
HDMI 1.4 does support 4K signals at 30 Hz.
HDMI 2.0 supports 4K signals at 60 Hz, although this is very new and not yet implemented in any device I have seen.

I haven't seen any HDMI to DVI adapter claiming to support more than 1080p at 60 Hz.
Note that while the adapter may claim to be dual link DVI, this could just be that the plug as the dual link pins.
These can be connected to DVI-D or DVI-I connectors on your graphics card or monitor.

The Xbox was designed to connect to a TV and these don't support refresh rates over 60 Hz.
Just use a HDMI to HDMI cable to connect your Xbox to the monitor. This will give you 1080p at 60 Hz.
