Will G-SYNC monitors support HDMI?

Muaz Hassan · Dec 21, 2013

I was just wondering, Ive seen that the asus vg248qe monitor doesn't have an hdmi port which is a bad thing for me. I know that g-sync technology isn't possible over hdmi at the moment but they should still include it for other reasons, for example i like to have my wii u and ps4 both connected to the same monitor. So will g-sync monitors eventually get this or is hdmi abandonded.

BTW i only plan on using hdmi for game consoles only, for pc i will be using display port ofc

side note: if anyone has a g-sync capable monitor then it would be very helpful if they tried playing on a ps4 or other games console via this g-sync monitor with some sort of adapter.

Thanks

the monitor may support hdmi. but G-sync currently only runs on display port.

The G-SYNC version of the VG248QE doesn't have HDMI or DVI ports.

The non-GYNC VG248QE does have HDMI, DVI, and DisplayPort outputs.

You would still be able to use that for your other inputs if you get one without the GSYNC Kit. However, due to the nature of HDMI and DVI (timed signals, instead of packets of information like DP is) GSYNC won't be coming to HDMI or DVI, but it's very possible other monitors that add it will still support other inputs, but only time will tell.

Gsyc fail right here
HDCP over DisplayPort is not validated in Windows 7 Media Center. How would I be able to run it with my cable card setup? http://support.microsoft.com/kb/2392252

HDMI, until version 2.0 comes about, does not support 120+hz. You aren't going to want to use HDMI with that monitor.

G-sync requires displayport due to technical reasons. G-sync can't work with other connection types with their current versions. Having one connection type also reduces input latency, so it is generally a good idea, for a gaming monitor, to only have a 1 connection monitor.

Actually I am researching in the same topic as well...

Despite not having an HDMI port, would it still be possible to use an HDMI to Display converter to connect a PS4, obviously loosing g-sync but in general would it even show the picture at whatever Hz or it wouldnt work at all ?

CraigN · Mar 24, 2014

It *may* show the picture at 60Hz, but I'm not sure, never tried testing it on my GSYNC Asus. But definitely not at 144 Hz.

HEXiT · Mar 24, 2014

depends on the monitors available refresh rates. some support a spectrum of frequencies 29 up to 144, others are very limited .

HEXiT :

I've learned recently that I can go into the Nvidia control panel and create custom resolutions with different refresh rates not normally given. I can also create resolutions beyond my monitors capability, which results in downsampling, though I am not thrilled with those results, but it is nice to have different refresh rates. If your game can run at a constant 80+ FPS, you can create a custom 1080p resolution at 80hz, and have smooth V-sync game play.

That's only assuming that the "strobe hack" isn't receiving its configuration from the computer, and doesn't reset when a new source is added.

Considering the PS3 doesn't even output past 60Hz, I doubt the PS4 will (you can say "but it's a next gen console" all you want, but the PS4 already has less media player features than the PS3 does, it wouldn't surprise me in the slightest if it was missing) so you won't be able to take advantage of strobing either.

The cable will most likely work for playing your PS4 at 1080p@60Hz, though, which I suppose as far as your question goes, that's all you need.

Edit: Just looked it up, the PS4 and XB1 both use HDMI 1.4 ports, similar to PCs still. So your max output will be 1080p@60Hz.

CraigN :

Strobing with G-sync is no longer a hack. It's simply an option to turn on from the monitor. Though it may have a refresh rate requirement, which may not work with a PS3/PS4.

CraigN · Mar 24, 2014

bystander :

I'm aware of this, I own a GSYNC VG248QE. I believe KevinAr18 was referencing the "hack" that gets it to work with Non-Nvidia systems. Although I believe the monitor button should work with non-Nvidia systems now.

It definitely has a refresh rate requirement at 120 Hz. 110 Hz might work too, but not 100% sure. I'd have to be in front of my home computer to check.

CraigN · Mar 24, 2014

Unfortunately I don't have a HDMI to DisplayPort cable, so i can't test it on my end.

Now that I am home, I can however confirm that it requires 85 Hz, 100 Hz, or 120Hz, and the PS4s HDMI port won't output past 60, so, even with the switch, you won't be hitting 144Hz on the ASUS unfortunately.

bystander · Mar 24, 2014

KevinAr18 :

Back in the CRT era, 75hz was really the point where the flicker no longer was a problem, with 85hz and above being pretty ideal. It should be fine with strobing at 85hz.

yeah nvidia recently released that option to allow people who can, to overdrive(overclock) there monitors.
came about the time g-sync went beta.

Gabor Petlyanszki :

Thats what I was thinking, I wonder if there is a HDMI splitter so one end takes the video and the other end takes the audio. Its really annoying because I really want a PS4 as well.

KevinAr18 :

Yes, an HDMI to Displayport cable will work on the monitor... even at higher refresh rates.
* but I'm guessing that the G-Sync "g-sync" mode will not work.
* However, G-Sync's "strobe mode" will still work in this setup! "strobe mode" requires a 120Hz refresh rate.

1. To drive the display at 1920x1080 @ 120Hz, you will need a cable like this:
http://www.monoprice.com/Product?c_id=102&cp_id=10246&cs_id=1024603&p_id=9475&seq=1&format=2
However, I would actually recommend that you chose a "high speed hdmi" cable that can support more bandwidth just to be safe:
http://www.bhphotovideo.com/c/product/889553-REG/Comprehensive_disp_hd_6st_DISPLAYPORT_to_HDMI_HI_SPEED.html

2. Go into the Nvidia control panel and enable "strobe mode" (and disable "g-sync mode")
3. Set your computer to 120Hz

For computer use, this will enable both 120Hz refresh rates and the "strobe mode" which gets rid of blurring during any type of motion in games, scrolling, etc.... This turns off variable framerates, however.

For the PS4, I am guessing that you will be stuck with 60Hz (simply because I don't think it runs any faster??) and can't have g-sync or strobe mode. If a PS4 can be set to 120Hz, and you find you really like strobe mode, then you can use a utility like this to enable strobe mode on the monitor itself even when connected to non-nvidia systems (like the PS4): http://www.monitortests.com/forum/Thread-Strobelight-LightBoost-Utility-for-AMD-ATI-and-NVIDIA

That cable you recommended is mini display port from HDMI, correct me if I'm wrong but aren't all G-sync monitors display port?... or are you suggesting I use a mini display port to full display port adapter?

Another problem is how can you get audio from the PS4 isn't display port video only but hdmi is video and audio?

CraigN · Jun 10, 2014

DisplayPort is also Video & Audio.

120+ Hz HDMI doesn't work on the VG248QE because it is HDMI 1.4a, not 1.4b or 2.0. Most HDTVs also use some trickery on the TV side to make even non-HDMI 1.4b compatible devices display the content in 120 Hz (similar to how 240Hz is really 120 Hz with inserted frames, or something like that).
#2 of what Kevin said is correct.
3) Also most likely correct.

You need HDMI 1.4B (not A) to get up to 120Hz at 1080p, but it's dependent on the device on the other end supporting it as well.
The VG248QE ONLY Supports up to 60Hz over HDMI. It's 144 Hz functionality is locked to its DVI and DisplayPort interfaces, because it's HDMI is only a 1.4a version port.

bystander · Jun 10, 2014

To be clear, HDMI 1.4b does not support 120hz either. It only appears to in HD3D by using a trick, but that trick does not work for 2D. Only HDMI 2.0 supports 120hz. HD3D supports 60hz (120hz if you add up both eyes) by using frame packing.

http://en.wikipedia.org/wiki/HDMI

HDMI 1.4b was released on October 11, 2011.[153] One of the new features is that it adds support to 3D 1080p video at 120 Hz – allowing frame packing 3D format at 1080p60 per Eye (120 Hz total).[154] All future versions of the HDMI specification will be made by the HDMI Forum that was created on October 25, 2011.[43][155]

Notice that it added support for 3D at 60hz per eye at 1080p (1.4a only supported up to 720p), but it does not support it in 2D.

CraigN · Jun 10, 2014

Ah, good catch bystander, my mistake.

Muaz Hassan · Jun 10, 2014

Just to clarify, I don't want to use 3D on the PS4 I just want 60Hz on my G-sync monitor (e.g ROG SWIFT PG278Q) via a HDMI (from PS4 or PS3) cable to a display port which connects to my monitor. I am aware G-sync will not work on the PS4 via my G-sync monitor. Can anyone find a HDMI to display port adapter or a HDMI that splits into display port and a audio end. The PS4 probably will never go past 60 fps anyway.

If anyone has a G-sync monitor then it would be amazing if they could test to see if a HDMI (from PS3 or PS4) to display port (connected to G-sync monitor) adapter works.

Thanks for your support
