How to upgrade the Phoenix (Clevo P870DM-G)from FHD to 4K (PICTURE GUIDE)

That was a great thing to learn. I think they are blue leds paited with phosphor, as I found an extented paper on the matter and tried figuring out this too. That would result in white light, without being white leds.

I would love to have one of this colorimeter things to calibrate my displays, but they seem so expensive.

 

Definitely they are LED painted with phosphor, but what I need to know is what color of LED with what color of phosphor... so Far people from Spectracal tells me I have to use the profile of a Blue Green LED Wide Gamut P3, but that is an option for their software and colorimeter ONLY.... on other softwares probably one would have to select Wide Gammut RGB LED since they do not have any other option. Not a problem for Spectrometers.... those do not ned calibration. The Spyder 5 is not that expensive.... and you might be able to get a Spyder 4 cheaper and use it with DisplayCal which is a fantastic software and free

 

Yeap, im pretty close to where i want my calibration to be, gonna try and see if i can get my hands on a spectrometer type device. Would be interesting how much of a difference that will make.
I got my Spyder 5 pretty cheap, so it was a no brainer choice.

 

I like where this discussion goes...interesting stuff!

 

So with the help of Prema and the instructions from Akaraah I was able to replace the FullHD panel with the 4k panel. Thank you guys! I run the phoenix now with g-sync 4k and sli (2 x 980m). The 4k panel has much better colours. However, I have the feeling that for the mobile version of g-sync to work correctly you need a higher refresh rate than 60 Hz, I guess in fact the 75 Hz of the Full HD panel would be optimal. Why? Because when the refresh rate gets lower than 40 fps the 4k panel starts to flicker when g-sync is enabled. It doesn´t flicker when the fps is above 50 fps or g-sync is disabled. The FullHD panel doesn´t show this problem.

So the biggest advantage of g-sync, namely smooth gameplay with low fps is not obtainable with this 4k panel. Ironically you see low fps particularly when using 4k resolution... I tried to overclock the 4k panel with custom timings but 62Hz is the maximum stable frequency. Reducing the resolution does not help to get a higher frequency because the pixelcount of the panel stays the same. I will do more testing, but I fear we have to wait for a 75Hz 4k-panel to enjoy the advantages of mobile g-sync.

On a side note: Because of the highly efficient frostbite 3 engine star wars battlefront is the only newer game that I can play with graphic settings maxed out at 4k and still maintaining fps of 50-62. In this case no flickering and the visuals are THE BEST I have ever seen Unfortunately other games like The Division have much lower fps in 4k and flicker with g-sync.

 

I have being playing ... well my son.. me watching.... The Division, without G-Sync, I we see no flickering or tearing at all...

 

interesting article about the evolution of LED backlights.

As I said, g-sync is causing the flicker

So i went back to the FHD panel for a 2 weeks and now im back to the 4k. The color quality and the gamut is way out of the FHD panels league.
Every single video or picture i could see banding in most of the places.

Sure i dont get G-Sync, but at this res it really doesn't matter. This panel is just beautiful.

I also compared it to my friends DreamColor laptop panel, and the stats on this one are way way better with more DCI P3 and Adobde RGB volume.

btw @victorwol his display had that clipping issue. Im still trying to find which panel his laptop is using, but it just doesn't look at good as this one. Will it be possible to share that final calibration data for DisplayCAL after you used the ColoMunki calibrate the Spyder?

 

LED technology has come a long way it's one of those background techs most people don't look at.

 

I approve this pun.

Thanks for posting that article, @victorwol. A good overview, and interesting to read through it.

 

Victor i dont understand why this same panel of auo 4k has different specs in the alienware,msi or this clevo laptops,supposedly this panel the auo B173ZAN01.0 should have the same specs in all the laptops but if you see the test in the alienware for example is diferent than the msi GT73VR in the alienware the brightness is higher than the msi GT73VR and the color is about 98% on the alienware and about 60% of the ARGB on the msi GT73VR,i really dont understand why using the same panel with the same backlight led and the same 400nits in the measure test's are different,it is just about the calibration or there is something else?the panel cannot be modified by the brand so how is possible that the alienware 17r3 get the 355nits on the highest bright point and the new msi gt73vr 6rf get only 325nits on the highest point also??is about the voltage?is higher on the alienware the voltage and in the msi less?all this don'st have sense because the panel cannot be modified on itself,if you see the measurements of the alienware on the website notebookcheck you will see higher brightness and much better color accuracy on the standard ARGB than the MSI GT73VR 6RF,how is possible that with the same f+`ng panel the measurements are so different?¡¡thanks in advance

 

I think you're right, calibration and power supplied by motherboard.

Also measuring display output is very finicky. The result is highly dependent on the testing procedure. Make sure the 400nit vs 355nit vs 325nit are all using the exact same methodology and equipment. I go by notebookcheck since they seem to be very standard in their tests and have been for a long time.

Also, this laptop from the OP will be soon re-getting a 4K panel, the original 4K was broken in transit to the buyer before me so it's got the original 75hz in it now. New panel enroute from china. Hope the cable still works since it RRP's about the same as the 4K panel!!

 

@Akaraah

I just installed the 4k panel on a P870dm-g and am having the issue with the gpus being stuck in low power mode. Are you saying flashing a non -G system bios from the link you provided earlier in the thread would fix the issue?

Will a P870dm system bios actually work on a P870dm-g?

 

Yep. It will, but for specifics I'd recommend talking to your reseller about receiving and flashing it, or messaging @Prema for extra help above all else to ensure it's done right (not assuming expertise I don't have) Check his site (premamod.com) for a flashing guide and go to the clevo repository for files, though that is riskier than getting the files from the company itself or from Prema (sometimes there's no telling how recent the files are compared to your stock bios and EC, just to consider all the caveats).

 

Are parts still around to do this?

 

of course,you just need to put in ebay the laptop screen and there is a lot of sellers, AUO109B

 

Yes. I also recently found out recently that on rjtech that they now offer the 4k 40-pin edp cable for only $45 usd, as opposed to the nearly three times I paid through Eurocom at the time: http://rjtech.com/shop/index.php?dispatch=products.view&product_id=30473

 

Another page from Rjtech: http://rjtech.com/shop/index.php?dispatch=categories.view&category_id=239

All parts for the p870dm models (1/2/3) they have. They even sell the gtx 1070 by itself for $750 which is pretty alright as far as notebook graphic card prices go. Heatsinks and fans too!

 

this link is compatible with other laptop models like msi gt73vr? the screen is the same auo109b so should be the same 40 edp pin connector right?

 

The GPUs wont be interchangeable.

 

Can't confirm for myself but I'm sure it should work if it's the same screen and the model in question has a skylake board. I'd recommend asking a reseller directly that sells the model for clarification though.

 

I saw the screen and cable for it on aliexpress and I am tempted to give the upgrade a try now. what other parts do i need?

 

Brains , Gonads and patience.

 

So long as it still works with the GTX 1070 I have

 

OK, so attempting to get a compatible 4K panel was a complete clusterf*** because the seller screwed me over. So Instead I found a compatible 1440p panel model from the P870DM model.

I'm hoping it works.

 

Is there a fix for the lack of brightness control on the P870DM-G with the 4k g-sync display? I understood the limitation when i first bought it, but I read some things about a possible fix for it. I just sold the laptop to a friend and would like to get it working for him if it is possible.

 

Got a n173dse-g31 today as a replacement for the Panasonic b173. However now I don't have any screen, and just have a black screen on boot with two tested GPUs.

 

2 out of 3 aint bad?
