6990m and 120hz is it possible?

Hi

I have called samsung/futureshop/techs, I have googled for hours. I have a np8150 with a 6990m. I bought a samsung 23inch 3d monitor that is 120hz. I am using Dual Link DVI to the monitor. I am Using catalyst 12.3. I have installed all the drivers that came with the laptop. I Have installed the monitor driver.

I cannot select 120hz in windows nor catalyst. Is the reason my 6990m?

 

well I may have answered my own question after 4 long hours of searching.

I found this: Benq XL2420T PROBLEM! Cant set 120hz at 1080p. Only lower res. - Overclockers UK Forums

Sounds like the np8150 is single link dvi. however im going to look into this further to see if its true! Also in display properties List modes for the 6990m all the modes are 60hz or less and thats linked to the card itself I assume, however I could be making an " out of U and ME".

says its dual link DVI, interesting problem. So what do you guys figure the problem is?

 

however im going to look into this further to see if its true!

 

Use the HDMI.

 

actually the dual link part of the dvi is only available on a nvidia cards bud, looks like your out of luck .

anthony says its dual link so im confused!!

why would the dvi port be differant for a nvidia card? the motherboards are the same!! or are they not? like cant i put a 580m in my 8150? or did sager develop a nvidia 8150 and a amd 8150? never heard of that before!!

well I dont know whats going on but I get 3d perfectly fine with the tridef software included and it looks amazing i moved into a plant in crysis warhead and got the plant to pop out about 1.5 feet sitting at a distance of about 3 feet from the monitor and all I can say is wow. It runs side by side 1080p and vsync is at 50fps so im happy with that because ill never hit 120 fps in 3d ever. infact the highest i get with a modern game is 70fps so 120hz is kinda pointless with a 6990m.

I have one question!!

when I turn crysis 2d into 3d using tridef it can popout quite a bit like over 8inches from the screen. when I use the tridef media player the image doesnt popout at all and the 3d effect is barely visible! Why would the game engine have better 3d than the movie engine? doesnt really make sense to me!

 

I'm not completely up on the ins and outs of 3D, but aren't those screens 120Hz because they refresh twice per frame so you get both the left and right image? So in other words, 70FPS in 3D is actually 140 frame refreshes on the monitor per second?

 

You half the FPS generated by the card too.

60FPS 3d will have the smoothness of 30FPS 2d.

 

Oh, I would have figured that 60FPS 3D as reported by the GPU would be 60 3D frames per second, effectively 120FPS. 3D without vsync must look terrible; potential tearing both within the frame and between left and right channels.

 

Nope, frames per second is frames per second, each eye gets half the frames.

You need 120fps to get 60 frames per eye.

The tearing will likely be very similar on both eyes due to the small times between frames.

 

depends on the monitor. on one mode its limited to 24fps but i dont lock the frame rates at 24 i play at around 50fps and experience zero trng with this monitor not sure why as it should tear?

 

Tearing is the difference between the FPS and refresh rate, so if you had it fixed to 24fps then there was no difference.

 

no what I was saying is I had it stuck to 24fps at first and had no tearing. I then turned off vsync and did not notice any tearing. maybe its the response time of the monitor 2ms ect im not sure why it doesnt show tearing. ive been trying to calibrate my monitor and find the best settings ect and testing it out and one thing it has yet to do is tear.

 

I have a similar setup as you but i'm running in xfire. I connect it to a samsung S27A750D 27-inch 3D LED through display port and I get 120hz. I think you can only get 120hz through display port because I also connect it using a hdmi and it only show 60hz.

 

edit: according to malibals website dvi dual link is only supported on nvidia cards the p150hm.

interesting and very bad news for me! thanks a million aduy you saved me alot of trouble. rep

I dont see the purpose of 120hz with a 6990m anyways. no game runs near 120hz for me! and besides amd hd3d needs a hdmi cable to work and thats what counts i guess.

I thought i was missing out 3d wise but im not. I have 2d-3d conversion without fps loss and its pretty good. I have tridef side by side that has incred depth, and if I get a hdmi cable Ill be able get better depth at 1920x1080 with amd hd3d. I might go as far as to say this monitor is absolutely amazing. the response time is the lowest possible, the 2d-3d conversion built in is simply mind blowing, the brightness is very very bright, with magic angle on the angles are unreal, stock the colors are amazing and rival IPS as I have seen in a comparison video, adjusting a few things makes something awesome even better. its only 23inches but to be honest just pull the monitor closer and walla

 

All current consumer 3D-display technologies are gimmicks. That is all.

 

interesting master chief. I think im going to return a monitor that gives me an extra dimension and more immersion with games and movies because someone thinks his opinion is fact. you trolled me twice! for the record

 

The DVI link on the MXM board must be single link.

 

Sirmetman,

The program will run as fast as it can to push out FPS. So if the game is running 100fps in 2D mode, It will only run 50 in 3D Mode. That is because it must render each eye as a separate frame, which takes processing power.

Also, if you are using shutter glasses, you get about 1/2 the brightness out of the 3D too.

 

Well, there are other things that happen in the game loop besides rendering... but yeah, I would expect it to be roughly cut in half. My point was that I would expect the system to report the number of full frames (for 3D, that's effectively 2 full res sub-frames per frame) rather then the number of half-frames as the frame rate. People are saying here that is not the case.

 

There is extra CPU overhead too, all of the geometry has to be calculated too for each eye.

 

i have a 3d hd tv, one of the cheap passive ones, and basically every other line is split between the two eyes with a polarizer, so you are really seeing two images at 1920x540, that are interleaved. nvidias crap 3d tv play just has frame stacking, which runs at essentially 1920x2100 at 24fps. however tridef 3d has interleaved output which interleaves two 1920x540 images, and outputs them at 1920x1080p. so basically i get 1080p quality 3d images at the 150% of the cost of normal 1080p rendering and at as high as 60fps.

 

aduy is the man, nice to read intelligence

passive 3d is pretty awesome as you don't need batteries. I have samsung battery powered glasses and for 5 batteries lasting 70 hours costs 2bucks on amazon. but over a few years its pretty expensive.

also

Samsung 2d-3d FTW

 

once youve played bf3 in 3d its hard to play it in 2d, and even with my machine and my passive tv i can play it at 35fps with medium settings on 1080p in 3d. unfortunately both tridef and 3dtv play are about 50 bucks.

 

I have 3DTVPLAY on my HDMI output only 560M GTX hooked to an Asus 120hz V278h monitor.

In order to use 120hz out of my monitor I need dual link DVI so Im stuck with playing at 720P@60hz or 1080p @24-30hz
thru this GPU

Both displays suck balls when playing BF3....Im ditching this laptop ASAP
