I am Thinking to Replace the laptop screen from TN to IPS panel. Is it possible? (Clevo P770ZM)

Currently I am using Clevo P770ZM. I do believe Clevo P770DM is using IPS panel, so I thought I might able to replace my tn panel to IPS panel. I've been researching which IPS panel is compatible with my 17.3 inch screen, and I've found this.

This is LG IPS panel, that is widely used by other 17 inch laptops. Is this screen compatible? The seller said this monitor is not compatible with my laptop, but when I chekced EUROCOM website, their clevo model is using this screen indeed. So... I am not so sure if the reseller is saying the truth or not. Can anyone confirm, if my laptop is compatible with this IPS screen?

 

That is the screen my P770ZM had as well, but perhaps he says not compatible because I believe the plug is different, as in you'll need a new cable as well as screen.

Now I could be wrong there, it's just an assumption

 

I thought most laptops use same connector for their display?

 

There's LVDS and eDP that I know of. I'm sure someone more versed in this subject can chime in

 

That is correct. Plus, you also need to match pin count, pin layout and (rarely) voltage. Though there's a lot of matching panels to choose from with most interface variants.

With the P770ZM there's two motherboard versions, one for LVDS and one for eDP (or four, counting TPM yes/no):

Spoiler: P770ZM, motherboard versions

Could check the labels, but easiest is simply to look up the current panel on Panelook. Some Clevos feature both connectors, btw. Not sure if that applies to the ZM; the Service Manual claims otherwise, but that also lists 15.6" panels for this model, so ...

Note that IPS is not necessarily superior to a TN; there's plenty of TNs that beat the stuffing out of the majority of IPS-like displays. True, the run-of-the-mills are pretty poor, but Clevo usually doesn't cut corners when choosing their displays, so ... check which TN you have before buying an IPS that may turn out to be vastly inferior. And when haphazardly ordering a new panel you're not buying an exact panel, but a ' 100% Compatible' (from your ebay link), meaning ' anything that fits'. This is a lottery, really, unless you insist on a specific panel only (or buy used).

Ah ... and a TN is oc'able to 90 Hz+ easily (maybe even 185 Hz ), whereas IPS will struggle as early as 75Hz. Provided your gpu can render the fps to match then this outclasses and obviates g-sync (apart from battery run-time), while making movies look better at the same time.

 

Holy **** 185hz LOL

My P750ZM has a TN, I should look into how high that thing can go. Do you know what sort of impact this will have on the cable or panel to go to, say, 120hz?

 

Cable and backlight will be fine and the lcd proper, too. Only thing is the lcd's circuit board; an oc can kill its controller chip (or its supports), since it's not designed for such high pixel clocks. Just take it 10 Hz at a time, find the first artefacting oc, then step back. If that setting keeps doing alright after several hours of continuous use (doesn't have to be gaming) then it's fine, but if it's going iffy after a while then it's overheating and you'll want to take it down a notch.

Avoid using evga for this, better stick with CRU (or anything else, really).

 

I've always just used the nvidia built in one @ the control panel. I've always just gone to 75Hz and called it a day, since the IPS panels in the G-sync models are just overclocked to 75Hz. I figure if they are publicly releasing that, that I'd be safe doing 75Hz. But my P750ZM has a Chi Mei TN panel, so I wasn't sure. Right now I have it set to 75Hz, but in the future maybe I'll look into how far I can take it. For some reason 60hz to 75hz is such a huge difference in smoothness, always has been with these ZM models, don't know why. I miss having 120hz in my AW17, sad that there aren't many clevo models with stable 120hz like the panther

 

Haha. I OCd my old 370EM to 140hz max but left it at 96/120 depending on the situation.

My 750 maxed out at 120(more specificaly 124) as anything above that had frame skips.

 

TN does tend to have a fair bit more headroom, though mine only did 100hz (the AUO 90% gamut 17.3" panel).

 

well thanks for the reply guys. I guess I will try to overclock my panel, and see what happens.

 

That's a 67% oc !

 

I know, but still needs more OCing.
