Need help getting 120hz on an external display with my laptop.

post #1 of 8
Thread Starter 
So I just recently got an ASUS G73JH, and it's quite the workhorse considering it's a laptop. Unfortunately, I cannot stand using 60hz panels anymore since I've gotten used to my Samsung 2233RZ which supports 1680x1050 at 120hz.

The problem:
The notebook only has VGA and HDMI outputs. I've tried VGA, and I cannot even get a signal using a VGA -> DVI converter. I've also tried HDMI -> DVI, and that produces a signal but I can only use 60hz. Catalyst Control Center says "Maximum reported refresh rate: 120hz", but nowhere can I actually select anything above 60hz.

I'm thinking it may have something to do with the built in display limiting the refresh rate in some way, but I cannot be certain. The GPU (ATI Radeon Mobility 5870) supports HDMI 1.3 (which supposedly has the bandwidth required for such resolutions and refresh rates). I have an HDMI 1.3 cable as well. These are connected to my monitor via an HDMI female to DVI male connector that appears to be dual link.

So, to summarize: I'm trying to use a 120hz LCD monitor with only a DVI input on a laptop that only has HDMI and VGA outputs. I get a signal with an HDMI cable plugged into the monitor via a HDMI female to DVI male connector, but I cannot select the proper refresh rate. The GPU supports HDMI 1.3 and the cable is in fact 1.3.

So, please OCN, help me out. I'd really like to use this laptop as my main gaming rig while at my parent's house and this display issue is my only motivation for getting rid of the laptop.

Hi,
Are you cloning the display, extending or using it as a single display only, ie when you get the 60hz source on ya monitor does the laptop screen go off?, if not then try single display then try 120hz wink.gif.

As far as I can tell, I've been telling the computer to only use the Samsung 2233RZ. I've disabled the laptop's monitor through CCC, the hotkey on the keyboard, and even tried in the device manager. There is only output to the external monitor.

Thanks for the suggestions.

idk it might be the laptop. my rig puts out 240Hz no problem on the big tv in my living room but when I hook up my laptop it won't push past 120Hz. It's an nvidia card on both though so I don't know if there is a difference when talking about ATI.

Can you click "show all modes" under the screen resolution options?

mobile cards usually have an output limit (certain res @ certain refresh rate). although I realize you have a beast laptop, I'm not sure it will do 120Hz

Yea, it shows all kinds of different variations of resolutions and refresh rates, none of which are above 60hz. CCC seems to be detecting the connection as single link DVI, so I figure that this may be caused by some software limitation. Doesn't tell me a lot though. Could be the laptop GPU, or it may even be the HDMI to DVI converter. The converter seems to be dual link (plug is full of pins, not like some DVI plugs that have two packs of pins that make squares).

ATI's spec sheet claims that this GPU (5870 mobility) supports HDMI 1.3, and from what I've read, that supports 3D/120hz.

Heading to sleep for the night. I'll check back here in the morning for suggestions. Thanks again, folks. I may have to look into an LCD monitor that natively does 120hz over HDMI sad-smiley-002.gif Pretty costly, and I'll definitely want to make sure that works beforehand.

Slight update. I can get up to 75hz on any supported res without issue, using Powerstrip. Anything above ~76hz will cause the monitor to either act like it has a signal but not show anything, or do the same but show a bouncing box saying, "not optimal mode" or something along those lines.

I'm beginning to suspect that I'm missing some other timing required for proper functionality.

Any tips or ideas? Still cannot select a refresh rate over 60hz in CCC or Windows, but Powerstrip allows me to force 75hz.

I've tried countless registry tweaks and reforce, but no progress.

Powerstrip seems the most promising, but I need to figure out why anything above 76hz causes the screen to go black but the activity/signal LED stay lit.

I'm in the same boat as you. I have a Sony Hz800 (240hz) 3d monitor. I've already used the laptop to watch 3d bluray on the monitor (using the glasses and emitter that came with the 3dtv). However, it would be nice to get games to run 3d too. I've connected my laptop (using HDMI to HDMI cable) to the 3dtv and when I use PowerDVD10 to run a 3d bluray (Mkv on the hard drive or a 3dbluray in the drive), the laptop take the 3dtv into a 3d mode full screen mode (and I can't click on the mouse or do anything until I click on the the powerdvd icon in the taskbar (to get out of 3d mode). At this point the 3d movie runs double (side by side and not in fullscreen).

Just want to know if you've managed this much before we go on.

Let me know if you got any further in 3d gaming on the laptop?

Thanks
