[Review] Sager NP9870-G / Clevo P870DM-G Review by HTWingNut

You can use Aida64 for verifying your screen panel.

 

Also installing MadVR will recognize the name and model of your screen panel, but Aida64 provides much more technical data

 

Thanks for your help! I will try it later after I get home! Thanks again!

Hello guys! I Tried to install aida64 extreme, I can't find the model in the this view. Is there any other view to see the model or it is all?

Sorry I am so noob with this, thanks a lot!

@t456 Can you take a look ↑↑↑?
This is from my P870DM

 

It is not the original SPF1, at least, that'd have PnP id LGD0469, not LGD046E. MSI has used the same display in some of their laptops, but unfortunately these too have an incomplete edid (the part nr. has been left out). Best option is to check the sticker on the back, but you could also try MonInfo and copy/paste the 'Raw data' section. At the very least it'd be possible to narrow down the list.

Mind that it isn't a bad display per se; all characteristics are nearly identical to that of the SPF1. Likely this a different production run or the official non-gsync version of the SPF1 <- scratch that, this one should also be g-sync capable.

 

Wow thanks for the image! I will try to reinstall the driver and see if it will display more details.

 

Hello guys! I tried to dig some more information but it seems that I am using a different panel. Also when I tried to install NVidia driver from fresh download it is giving me this error "the graphics driver could not find compatible graphics hardware", but I managed to fix it by updating an .inf file in NVidia driver folder.

Also my problem now is that I can't see any G-Sync option in NVidia control panel, I am thinking if it was caused by a wrong installation of driver or the panel is really not G-Sync certified?
Plus, Output color depth is turning to 6bc if I set it 100hz, and turns 8bc when I set 60hz (native) or 75hz (custom). Please see attached file below.

Update: Uploaded NVidia control panel image.

 

It's one of these four.

Unfortunately, you have a non-gsync edid. It's the same with the SPF1's; some are certified and will run, others are left at the stock 60 Hz. Whether this has anything to do with its actual capabilities and binning or whether it's just a matter of flashing a different edid is up for grabs. At any rate; if you paid for an original then you're good to RMA (since it's not an SPF1). Then again, that model also had gsync and non-gsync varieties, so there's still a chance the replacement will again have a non-gsync edid.

Flashing a validated 75 Hz edid should work too, of course, but not sure if anyone has managed to do that on this specific laptop. Also, to start with you'd need to find one. Have those of the SPF1, but couldn't find any for this unknown panel. Might ask in the MSI GT72VR and HP Omen 17 Owner's Lounges for a MonInfo dump.

 

Thank you very much sir! I am now trying to contact the reseller to clear things up, I will be really disappointed if this is not a gsync panel. I have waited almost a month for the RMA and this is what I get, very disappointing. But nonetheless thank you very much for helping me! Really appreciated!

 

If you have Thunderbolt enabled, will that only sacrifice just one of the DisplayPorts?
Can you have 2 external displays plugged in to the thunderbolt port and one display plugged in to the mini displayport all at the same time then?. I know this is late. But I really need answer. How would you plug in 3x acer predator xb271hu and achieve the max refresh rate? the predator has HDMI 1.4 by the way, so the highest refresh rate would be 60Hz. But it also has a mini displayport capable of 165Hz max.

 

And is this the same with P87Km1?

 

You can configure each passthrough individually in the BIOS so yes you can run 1 + 1.

 

Thanks. I have seen the BIOS. I will put one monitor in the mini DisplayPort and two monitors in each of the Thunderbolt 3 ports, so that will be a total of 3x Acer predator xb271hu 1440P monitors on at the same time. I hope that the Thunderbolt 3 controller will split one of the DDI bandwidth to 2 displays to each of the 2 Thunderbolt 3 ports that are available. I will not use the HDMI at all, as the 27 inch Acer predator xb271hu HDMI 1.4 will only support 60Hz. I will post the results on the P870KM board stating my max refresh rate on each monitor. See you all soon. Time to get some equipment then!

 

The displayport signal from the GPU is not there when directed to the thunderbolt ports.
