Carbon X1 (3444-G7U) - DisplayPort to HDMI cable Not Working

2016-05-06, 20:05 PM

I purchased a MiniDP to HDMI cable that is capable of 4k resolution. I hooked it up to my X1 (Gen1, model 3444-G7U) laptop into my LG TV (which also supports 4k). I can't get the TV to go above 1080p! Again, the TV is brand new and 4k capable, the MiniDP to HDMI cable is 4k capable, and it's connected from my X1 laptop's MiniDP port.

What I understand is that hdmi cable can only support 1920x1080 resolution since I never seen anyone use hdmi cable on 4k if you want 4k you would have to have screen with dp port and then use a dp to minidp cable for the actuall 4k support.

That's a good question but I still doubt it will ever support 4K on 1 single monitor through HDMI since all the modern monitors uses DP for higher resolution than 1920x1080 due to HDMI does not support more than this so let's say if you buy Asus gaming monitor it will only have DP port due to I uses 2560x1440 resolution which HDMI cannot support so therefore they used DP due to that port supports up to 4K or so.

I just did a little digging - turns out that HDMI 1.4 does 4k, but only at 30Hz. HDMI 2.0 on the other hand does support 4k at 60Hz! I'll be buying this guy and trying him out: http://amzn.com/B0194F1MPI

you can bookmark this url https://en.wikipedia.org/wiki/HDMI#Version_comparison it will tell you each version what it supports :)

 

Just keep in mind cable itself must be 2.0 as well so adaptor you got linked may not work well so if you got the adaptor and then a 1.2 HDMI cable then adaptor will act as 1.2 or may not work at all depends but it wont be able to give 2.0 use through a 1.2 or 1.2 HDMI Cable with the adaptor.
