What is the Refresh Rate of Sager NP8657-S's Display?

I'm looking to buy a Sager laptop, either the NP8657-S or the NP8658.

The customization options for the display are:

15.6” FHD 16:9 LED Backlit Wide screen (1920x1080) Super Clear Matte Type Screen (SKU - S1R327)
15.6” FHD 16:9 IPS LED-Backlit Display with Matte Finish w/ G-SYNC Technology (1920x1080) (SKU - SSC884) ( + 80 )
15.6” 4K QFHD 16:9 Display with Matte Finish w/ G-SYNC Technology (3840x2160) (SKU - SSC886) ( + 200 )

Anyone know what the refresh rate on these displays are?
Thanks,
Ed

 

If it says gsync, it's probably 75Hz at 1080p and 60Hz at 4K. They're all 60Hz panels, but the 1080p ones will be overclocked via the BIOS, most likely.

Let me be clear: there exist no currently-created post 60Hz panels for laptops anymore. 120Hz is dead right now, and 144Hz has never existed to my knowledge for laptops.

And if they exist, absolutely nobody is using them.

 

On my P770DM-G (Eurocom Sky X6) the panel came running at 60Hz. I OC'd it myself to 75Hz.

 

What about the one the that's not G-SYNC? And for the ones that are GSYNC, are they overclocked already? Or do I have to do it myself?

 

The gsync ones are pre-overclocked. I don't think the non-gsync versions are at 75Hz, but I could be wrong. Call a reseller and ask.

 

Ok, thanks. Slightly off topic, but since it would be at most 75mhz, is it true I won't notice much performance improvement between the 980M and the 970M? I play mostly crappy (non-GPU intensive) games like DOTA 2.

 

Most probably not.

 

Correct. 1080p gaming will not stress out a 970M enough for you to notice the difference between 970M / 980M.

 

Well I would still get the 980M if you can afford it... It's more futureproof...

 

My Clevo P870DM-G (GSYNC) came with a 17.3" LG Philips LP173WF4-SPF1 IPS FHD Matte Screen and it is 75hz by default. I didn't need to overclock anything. In fact, there is no option to choose 60 HZ. Only 75 HZ

 

In the case of the games he listed, yes. In the case of other games? A single 970M is a joke to me

If you can't set 60Hz in NCP or in windows, something is wrong.

That is a 60Hz panel overclocked to 75Hz in the BIOS, just know that

 

I'm glad that I can't, I don't even wanna see the light of that jerky 60 Hz motion I can feel the jerkiness of a 60 HZ panel even when moving a window quickly in a circular motion in 2D Mode. Let alone 3D Games

 

You should not be glad you can't. There's games that need 60fps/60Hz. There's games that won't use 75Hz or 120Hz. Your monitor should be capable of choosing 60Hz.

 

Well I don't see a problem here, everyone told me before I bought it when I asked if its 75hz by default or do I need to overclock it, that it is 75 HZ by default as it's factory overclocked. I can always create a custom resolution of 60 hz if I need to.
PS: this is both on the official CLEVO driver that came with the laptop and the latest garbage drivers from nVIDIA

 

Well then you can set it to 60Hz. I was under the impression it was not possible for you to do so.

 

Just Oced my LG 1080p IPS display to 75Hz... Let's see what happens in games...

 

Thanks D2 this is very helpful! I have a Clevo Vortex with i7 4800MQ + GTX 880m + 1080p display. Problems I have with overclocking the refresh rate:
1. I don't have any display related options in BIOS (F2). Not sure how exactly can we change it in BIOS?
2. I saw from some other threads nvidia control panel has this "create custom resolution" function. But given i'm on a laptop it runs HD4600 when in desktop, so i don't even have the option display menu in nvidia control panel.
3. I did manged to find a similar function in intel graphic settings, however when trying to setting any refresh rate above 60 (even 61Hz) it prompts " custom resolution exceeds the maximum bandwidth capacity"

So does this mean my display just cannot be overclocked?

Thanks!

 

I don't know what a Clevo vortex is, but if your laptop is non-SLI, then your GPU is the intel GPU. Your 880M is a glorified number cruncher and does not affect your display in any way, so you cannot overclock in Windows until Intel fixes their custom resolution feature in drivers. I.E. makes it work at all.

You don't get overclocking options even in laptops that DO overclock via BIOS keys. The overclocking is automatic, and you cannot use it if your display is your second monitor (it'll max out at 60Hz).

See first sentence. Blame Optimus. Realize Optimus is bane of existence for all gaming laptops beyond midrange and that MUX switches are the king. Eternal sadness.

That'd be the LVDS limitation, most likely. Even if Intel fixes their custom resolution feature, you may saturate the LVDS bandwidth, and you don't have eDP on that machine, so you're likely stuck at 60Hz.

That it does, sir/madam!

 

Thanks!

So if i get a SLI, increasing refresh rate is possible then?

Or can i get a 60+ on an external monitor? Not exactly sure what you mean by the second monitor being maxed out at 60Hz.

 

You don't need a SLI machine. Any machine that's got a mux switch or is directly wired to the nVidia/AMD card can technically do it. The P7xxDM and P870DM machines are hard-wired, and the P65xRx3 and P67xRx3 models have mux switches so they can do it in dGPU mode.

If your laptop monitor is your primary display, it will allow the BIOS OC of 75Hz default to be shown if using one of those gsync models. If it is your secondary display (and an external is your "primary display") then it will be locked at 60Hz, because the screen isn't naturally rated for 75Hz.

If your second screen has 120Hz or 144Hz or any post-60Hz resolution built in, then you can enable it as a secondary display. Otherwise, custom resolutions do not work for secondary displays. If it does not have such refresh rates built in, but you make it your primary display, you can custom-resolution-overclock it as normal.

 

super helpful! very much appreciated sir!

 

i'm looking this model: Sager NP8658-S. It says the model has g-sync built in monitor. So assumes it can go 75Hz and i don't actually need to manually change it from BIOS?

 

Oh. My absolute bad, sir. Sager model names confuse me, I for some reason thought you had a P15xSM-A instead of a P65xRx.

Yes, that model has a MUX switch and a built in 60Hz (BIOS OC'd to 75Hz) monitor with Gsync support.

 

If you've overclocked your panel, you might want to check that it's not skipping frames using the following link, you use a digital camera with a fairly long exposure to take pics of the screen during the test - after taking multiple pics of the screen in each photo you should see no 'missing/skipped squares': http://www.testufo.com/#test=frameskipping

Also, I'd recommend overclocking as far as you monitor will allow without crashing the screen and without frame skipping (test above). That's how I arrived at 78Hz - 79Hz crashes & there's no frame skipping at 78Hz for me.

 

hi D2, thanks for the help along the way. I've got this Sager N8658 model w/ g-sync screen - have looked through BIOS and seems there's not option where i can change the refresh rate (re your point BIOS OC'ed to 75hz). Assumes i cannot manually change it and it already is 75hz capable?

Also i'm not quite sure of the MUX switch - i'm a heavy bettlefielder and is there anything i can do with MUX to maximize the performance? (now i'm running ~150 - 180 FPS, with of course the monitor being 60hz g-sync)

 

As long as your primary screen is the laptop display and it's a 1080p gsync panel, it should be able to set to 75Hz via either nVidia Control Panel or the Display Properties window via Windows' own display settings.

The MUX switch changes from the iGPU running your screen/games to the dGPU running your screen/games. I believe it should have an Optimus feature too (where the iGPU runs the display but the dGPU is a number cruncher for framerates; I believe I explained that in this thread already) but the best performance is from dGPU only. If you already have the ability to enable Gsync, then you must be on dGPU-only.

 

is it possible to overclock y50 display?

 

With Optimus, no... It won't be possible... Also Y50 doesn't have a dedicated only mode so that is a definite no no..
