Clevo P650RA Screen Upgrade

Hi.

I bought a Defiance II laptop from PC Specialists a while ago and recently damaged the screen.

It was a 15.6" 1080p60 screen which shows as a "LG Philips LP156WF6, and is an eDP, 2 channel, 30 pin lower right side (I think). The motherboard is a Clevo P65-P67RGRERA

I can replace the screen myself but I'd like to upgrade it to something better, preferably a 1440p 120Hz or 144Hz but I'm not sure a compatible display exists for this.

If not then a 1080p 120Hz or 144Hz. I play a lot of Rocket League on my laptop so the higher frame rate would help. My GPU is a 980M and it can run the game at well over 200fps in Ultra settings so I think the upgrade is worthwhile.

What would be my best option to upgrade to?

I have spent a bit of time looking through the old threads on here but would just like some updated info if there is any as a lot of the threads about compatible displays are years old (because my laptop is over 3 years old )

I'm in the UK and cannot find any official sellers for a BOE displays (for example). All I can find is "compatible" or "like BOE" displays. I found some displays on AliExpress which might be real but it's obviously a gamble that they'll just be the same "compatible" fake versions.

Thank you in advance.

 

I cannot find any 3k 120/144Hz display that would be compatible. Is there one?

I think the best option for my system would be a BOE NV156FHM-N4B which is 1080p144. Are there any better alternatives?

A guy is selling them on the US eBay site. https://www.ebay.com/itm/Dell-Lenov...reen-Display-LED-144hz-IPS-15-6-/293073041861

Are these genuine BOE screens or are they "like BOE" displays fakes?

Thank you.

 

That is probably the best screen you can get for 30 pin as that's the one I have. I wrote a long review about its and a number of other people have it here . You can find it here if you want to read it . Just try and go from a reputable dealer. Your best bet is probably rattikin or AliExpress if you don't mind the long shipping.

 

I did read your review and that's why it's in my wish list.

Do you think the displays in that eBay auction are genuine BOE?

Cheers

 

According to the people I talked to, they get it direct from the factory there. Haven't gotten from an eBay dealer myself and I am pretty impressed with the quality of it. Otherwise AliExpress probably your best bet.

 

The seller confirmed that these are genuine BOE parts so I've just ordered one. I will update here after the upgrade.

Cheers.

 

Hi. So I received the display last Saturday and finally got around to installing it today (literally takes less than 10 minutes, I was very surprised how easy it was!).

First off, the display is much brighter than the LG display I replaced, I have the brightness setting set to 50% whereas I was using about 80% or 90% previously. One down side is that the colours seem more washed out but I altered them in the Intel Control Panel by increasing the saturation a little bit and it seems much better. The function brightness keys work the same as before, which is good.

I played a game of Rocket League at 144Hz and it was pretty awesome. Very happy with the upgrade so far (30 mins in! )

A couple of questions;

1. Is there a driver to use for this screen? Windows still recognises it as a Generic PnP 143Hz monitor (not 144Hz). I saw you say this was a native 150Hz screen, but V-Sync limits it to 144Hz. Windows Monitor Adapter properties also gives me only the choice of 60Hz or 144Hz too.

2. Are there any colour profiles I could load into the Colour Management settings for this display?

3. The first three times I loaded up Windows 10 and tried to open the Display Settings Menu, it gave me the White screen of death. Anything I did in the background, such as press the Windows key, could be seen when I slept and woke up Windows again but the screen was totally white until I pressed the power button to sleep the laptop. What's up with that?? Do I need to change some Windows setting or driver for the new display?

Anyways, thank you for your thread about this display. Your recommendation led me to getting one and it seems excellent for the money.

Thanks.

 

So there is still something not right and I think it's related to the white screen of deaths I was getting earlier. I have an issue where if I try to open this particular webpage then the screen goes very white and it looks like the image is being displayed at the wrong refresh rate or something and the image is rapidly overwritting itself.

I can make out where the cursor is and close the web browser, but the rest of the programs continue to display with this issue until I put the laptop to sleep and wake it up again, and then everything is normal

If I change the monitor properties in Windows to 60Hz then this issue seems to resolve.

Is this an issue with the type of display port I'm using and the signal needed to display this webpage? Do I jut leave Windows in 60Hz all of the time?

Also, changing the refresh rate from 60Hz to 144Hz gives me the white screen of death until I sleep and wake the laptop.

So my question is, if I set Windows to 60Hz but I run games with VSync turned off so they run at 144Hz, is the monitor actually displaying 144Hz in game or is it displaying 60Hz and missing the extra frames? The FPS counter says 144Hz but is this then restricted by the Windows frame rate?

 

Well I'm glad you're happy with that so far. There are no driver's that I am aware of, in fact I believe only dedicated screens that are external have drivers. Ask for display profile so you'll have to get a spider device to get one custom. As for getting the white screen of death, are you sure the EDP. Port is plugged in all the way? I said it could go up to 150 Hertz oh, but I do not recommend it. Just stay at 144. If you're not getting 144 you should be able to set it to custom as that.

 

I'm not certain about this and I had it happened once because I decided to set at 30 Hertz switch entirely screwed it for a brief while. Just turning off the computer for a little while same to cure it.

 

The difference between 144 and 60 should be literally. Obvious

 

I did play around with it for a couple more days and if I set windows to 60Hz then I cannot play a game in 144FPS using my discrete GPU. It says 144FPS but it's still 60Hz.

I made another thread about the white screens of death and issues I am having. Hopefully you can help me out?

It seems then the screen is using optimus and you may have to set 144hz via the intel menu rather then nvidia. I have a laptop that uses solely the gpu for display, so I dont have this issue. Perhaps Gsync has something to do with this? You may have to play around with your bios as well, maybe disable either optimus or gsync, I am not certain.

 

Where you ever able to figure this out OP? It was just re-seating the cable that fixed it?

 

Apparently I never had it in all the way... It has to snap in with a definitive sound that you heard while taking it off.

 

Hi. Sorry I never got an alert for your post.

No, I haven't resolved that issue and I've lived with it. Actually I'm trying to fix it now with a new thread, here....

http://forum.notebookreview.com/threads/laptop-screen-issue.832441/

Do you have the same issue and did you manage to fix it yet??

 

I've gone into great depth on a similar issue with the same model display, check my post history.

Only up to about 30% of my display can be covered by pure saturated colors before it cuts to no image. This doesn't include black, white or grey. This means that display usage is fine 99% of the time, but some websites or images/videos will cause occasional picture loss. I can mitigate this by blocking certain problematic website elements permanently with an adblocker, or by using the color calibration tool in windows to lower all values.

Your problem doesn't look like the eDP cable but it's possible. Probably G-sync is the problem as I've seen issues before where people with g-sync laptops have problems with display upgrades more often, even if the upgrade is also g-sync compatible and gets g-sync data on the same pin as the original screen. I'm not sure why but g-sync seems to be finicky. If you can find a way to disable that if you're using it, or continue to mess with video drivers you might be able to fix it.

For my issue, the most likely reason is the wiring in the cable. When the display logic is asking for a certain voltage over each of its input power wires it usually can get exactly what it wants, but the specific eDP cable HP uses in my laptop (15 bs234wm) doesn't have an individual wire for each of the four input power pins to the display, but rather solders one wire to a pair of pins. This would then mean when the screen needs to lower voltage for a certain circuit (like for green pixels) on pin 1, but keep pin 2 high, it can't get it with my specific eDP cable because both pins would share the same wire. Again this is only a guess. But because the display can show full white, grey, and black, it means it doesn't have a problem getting the power it needs for max brightness on sub pixels, ONLY when one subpixel is very low and one is very high, and that color takes up more than 30% of the screen.

 

Hi.

Thanks for the info.

I've adjusted my RGB values down to 225 each, so I'll see if this affects anything to do with the issue.

I've taken the 30pin eDP cable out and I dont have multimeter probes small enough to check continuity on that cable. The cable I have is a 6-43-P6501-042-1C.

My monitor is a BOE NV156FHM-N4B.

My laptop is a Clevo P650RA 6700HQ.

Do you know if the two are compatible? If not can I just replace the cable?

Thank you.
