Y50 Thread

Why don't you consider the P35G in the equation since it's supposed to be IPS and 15" ?

The p35g v2 is not considered for me because:

1. The 860m is a Kepler instead of a maxwell (significant IMO)

2. It simply is overpriced for what it is IMO. If it were about 100 dollars cheaper, I would give it more consideration.

 

I always click quote instead of edit >.<

 

Fair enough. I'm still waiting for the release prices of both in Europe. Tough to find "the one"...

 

This might be a stupid question, but will this RAM kit work with the Y50?

I don't know what country you're from, but Lenovo Denmark quoted price of 8000dkk, it's around 1050eur. For the cheapest configuration as far as I understood.

 

Oh I was talking about Gigabyte P34G and P35G. The Y50 might be cleared from the list because of its TN screen...

IPS VS TN

https://www.youtube.com/watch?v=XPHkXqWqNW0

 

first, this is the Y40 not y50
in this dissembling review, the y40 is shown to HAVE AN M.2 CONNECTOR, HOWEVER, it is hooked up with the WIRELESS card. so if you want an SSD you can take out the wifi card and plug an M.2 in and get a USB wireless adapter, and the same applies to y50

 

So I'm getting really tired of waiting. Has lenovo confirmed that even the 4k screen is TN? If they have I think I'm just giving up on this laptop.

lenovo hasn't confirmed anything about 4k so Idk why you are giving up. the only thing we know is that it will be a samsung screen

 

Let's hope its the samsung PLS screen because according to the MSI forum it is an IPS type, the same panel that MSI is advertising on its MSI GE60 Apache Pro. If that is true you may want to add the GE60 to the list of alternatives for the Y50 if you don't mind sacrificing a thin body.. This is for those who are screen savy.

 

There have been past posts of people claiming that lenovo reps have stated ALL--including the 4k panel, will be TN. If that is indeed the case, then I'm looking elsewhere.

The problem with the ge60 is that its cooling is absolutely atrocious, at least from what I've heard.

Do you guys think the Y50 can output 4k on a 4k display?

Cause I dont see the point in getting 4k on a 15.6 screen

And what can we speculate on the battery life of this laptop?



Sent from my HTC6500LVW using Tapatalk

 

Battery life is expected to be 4-5 hours

Sent from my Nexus 5 using Tapatalk

 

and basically everybody on this forum is saying that whatever the reps said about the tech specs stuff are complete bs so Idk why you didn't get that part too

 

do you have the model number of the ge60 apache pro panel? if you do I can compare it to y50's 4k panel model number to get more clues

 

Do you think thats 50% brightness and regular surfing ?

Sent from my HTC6500LVW using Tapatalk

 

Definitely not - more like 20% brightness. 4-5 hours is probably the max it will be.

 

Damn you really think so? Can't wait for some one to review this laptop

The model number of the 4K panel listed in that maintenance manual is a TN panel. Unless that maintenance manual is wrong, or something changes in the supply chain between when that manual was printed and when the 4K model is available, I think we can be reasonably sure it will be TN.

 

I don't have the model number. I just saw it on the thread of msi ge60 apache

@xxxxking yxxxxx

Yes the apache has a heating issue but I think it can be resolved by repasting the heat sink and adding a cooling pad. That is why I'm hoping the y50 would run much cooler
considering it has 2 vents.

 

that makes no sense, currently there's no info on the model number listed on manual so you are assuming too early.

 

This video is mostly useless (though I only watched a couple minutes). Comparing input lag between one IPS display and one TN display will tell you basically nothing, except for how the those two specific monitors perform against each other.

I have at least 4 IPS computer displays, and by my tests, each of them performed differently in terms of input lag (with a DSLR and timer application just like the video). I also have numerous TN displays, which also performed differently. I have IPS monitors faster than TN monitors, and TNs faster than IPS. The closest pattern discernible is that the newer the display, the faster. There was a period where IPS monitors were just horribly slow with processing lag, and that changed with Dell's e-IPS (which I think are actually LG's) cheap displays around 2008.

There's a lot of confusion on these boards about IPS vs TN. First of all, there are IPS screens that use the same 6-bit "Frame Rate Control" interpolation of colors that TN panels do. Here's a simple test for you:



Assuming the forum didn't compress the image, this is a 1920x1080 image of a gradient top left to bottom right of total blue, RGB (0,0, 255), to total black, RGB (0,0,0). Making your image full screen, you should see all the different shades of blue without "banding." You'll know banding when you see it. This isn't a totally fail safe test, but if you see banding, then I don't think your monitor is 8-bit. This can be on IPS or TN. However, before you freak out, know that even 6-bit IPS panels should still perform better, and potentially be near 70% Adobe RGB, compared to TN, and that is a lot to do with IPS as a technology.

tl;dr: IPS isn't automatically slow with input lag and it isn't automatically amazing with color. However, it does produce a consistent tone across the screen (assuming it doesn't have a horrible backlight) with great viewing angles, and this does automatically make it better than TN. Those who are "okay" with TN viewing angles are probably just used to it, the same as those who are "okay" with pictures taken from a phone (yes, I own a Lumia 1020, and no, it still doesn't match DSLR).

Some others on here are puzzled by how someone would want 4K resolution on a 15.6" screen. For me, if the 4K screen is PLS or IPS, then I'd be willing to pay $300 more, and set the resolution to 1080p if I had to, but I guess I'm just picky.

 

No. 1.35v memory only.

 

Wait, what? We already had this discussion a couple weeks ago.

The Y40/Y50 Hardware Maintenance Manual was posted in Post #1984.

Here's a link to the manual for those who don't want to go back to Post #1984 to find the link.

On page 93 of that manual, it lists the model numbers for the various screens that will be used in the Y40/Y50 line. Under the 15.6" section, the only model number that has UHD in it is: SDC LTN156FL02-L01 UHD G S LED1 NB LCD 18201586 N. All the others have FHD in the model number.

Several of us, including you, then did searches on that model number and we learned that it's made by Samsung and based on other panels with similar model numbers, it appears the LTN156 part means that it's a TN panel that's 15.6".

Did you forget about this or are you now saying that what's listed in the Hardware Maintenance Manual does not provide us info on the model number Lenovo plans to use?

 

There is a review on a Bulgarian site : Ревю на Lenovo Y50 – наследникът на една геймърска легенда | Лаптоп.БГ – Новини и ревюта за лаптопи

I'll try to summarize in case google translate could not perform well .

1) Weight is 2.442kg with conventional HDD (not SSD)
2) pixel size is 0.1799 х 0.1799 ( panel density 141 dots per inch )
3) average brightness is 217 cd/m2 and the maxium inclination is 15% in the top left/right corners
4) colour coverage is 57% sRGB and 43% Adobe RGB
5) AFTER calibration the values are 196 cd/m2 , contrast 242:1 , perfect colour temperature D65
6) sound is very above the average in this segment
7) battery test--> Wi-Fi on, 120 cd/m2 brightness and Power Saver (ON). Script loops over 70 web sites ( one site per minute is open).Some of the sites contain flash etc..The result is --> 6hours and 40minutes
*) playing 720p movie, the result is 3h and 11 minutes
*)metro last night (everything on max) -->63 minutes
Please note that this notebook has been used before and it's not brand new
8) Temperatures (not mentioned in details), but slightly better than the previous Lenovo generation

THIS IS PRE-RELEASE MODEL AS OF 14.04.2014 AND THE ACTUAL MODEL COULD BE DIFFERENT

People living in EU could buy Y50 from the Bulgarian company on the same price for the same model as in US , the only difference is that OS (win8.1 home) is NOT included. This is the company and upon request i could provide you contact details..

Hope this helps !

 

Thanks a lot nexxen!
So these guys in Bulgaria already have y50 in stock? If so, why they haven't tested final version instead of pre production?

 

They say that we can preorder and the delivery will be "after 15th of June". They don't have the final version yet, this why they tested "pre-production" model as of April 2014. I'm 100% sure that there won't be any differences between this model and "final" release .

 

They said that it's not accurate to measure the temp in the "pre-release" , so they will update the review with the temperatures of the final model (when they have it). Forgot to mention that all gaming benchmarks are done using 337.50 beta drivers, so they expect even better results with newer drivers, which leads me to the conclusion that 860m 4gb is complete beast ( it's will be on par with 755m SLI ) and completely above 770m 3GB

 

I have as well noticed on the pre order page that laptop weight is 2.44kg. ? Isn't it 2kg?

 

It's a speculation at this point - but given the specs and the tests (that were done with i5 instead of i7) that ran 4-5 hours I wouldn't bank on it. XPS 15 for instance will get you 6-8 hours, but it has much larger battery. GS 60 3-4 hours, Razer Blade 14 2014 4-6 hours. I guess it will depend on the CPU, screen choice etc.

There was a report on last page that said over 6 hours, but there is a typo in the report - it says 280 minutes which is 4h40m instead of 6h40m - so we still have to see .

 

Seconded - people say that 1080p is fine and yes it is. But after using XPS 15 that has UHD 3200x1800 in its 15.6" format - I'm almost willing to deal with the 750m just because the screen is so beautiful to look at. I think 1440p for phones is a waste, but for 15.6" display - why not, it looks amazing!

 

Yes I did say it was most likely a TN panel, not because it starts with L TN but I forgot the fact that Samsung had PLS panels and thought Samsung only had TN panels. The LTN is only a serial name and doesn't not say anything about the panel type. For example, all of LG's laptop lcd panel starts with LP regardless of what type of panel it is. i.e. LP156WF3-SLB1 is an ips panel while LP156WH1-TLC1 is a TN panel. LTN simply tells us it's Samsung and nothing more. In fact after knowing that the GE60 003 uses a PLS panel makes it more likely that the 4k model will also have a PLS panel

So far we can only infer that the 4k panel, according to the model number, is glare/glossy (G) and narrow bezel? (NB?) 4k (no crap) LED backlight, and at last a Samsung panel

 

those are interchangable

 

If you say so then. It doesn't matter if he fries his motherboard, its on you.

 

Until you (or someone else) can show me a Samsung PLS panel with LTN in the model number, I'll continue to believe that the TN in the model number is not a coincidence.

 

Anyone has any idea how powerful the r9 m270 is.... Haven't managed to find a single review....

Sent from my LT25i using Tapatalk

 

M270x is a relatively weak GPU, definitely weaker than 860m by a big margin. Honestly I see no reason whatsoever for anyone to get the y40 over the p34g v2

Sent from my Nexus 5 using Tapatalk

 

Since the r9 m270 is a renamed 8870m or 8890m , it should be at least as powerful as the gtx 760m

 

I'm aware it's a weaker gpu... Just was surprised to see that there have been no review on it...

Also... people have quoted notebookcheck which states that 8870m is as powerful as a 765m... So it should be very decently powered...

Also p34g costs way more... The y40 is $1099 with a 256gb ssd... Which is not a bad deal...

Sent from my LT25i using Tapatalk

 

I would get the y510p at that point...

Sent from my Nexus 5 using Tapatalk

 

Not a bad deal, but not not a good value as well. The new ge40 packs an 850m ddr5 for around 1129. Thats with windows and an i7 4700hq. The new 15" sager with a 850 ddr3 slides in at around 1020 with an i5+850m ddr3. Both offer more performance than the y40. It was a blunder to put a r270m in the y40.

 

I don't need to prove to you how samsung names their panels.

 

LTN125AT01 IPS Replacement laptop LED LCD screen

This was from very brief searching, so pardon me if this site is incorrect with its description. The model number LTN125AT01 is associated with the ThinkPad X220, which other sites verify used an IPS panel, though I did not find the model number listed in the hardware guide for the X220.

PS: Before anyone goes to the above link and points at that it is listed as being 6-bit, and therefore evidence that it is actually TN, please refer to my previous post which explains that 6-bit frame rate control displays are not limited to TN.

 

Ownage gg

 

It's interesting because I aslo made a search and most result return that unit is LED and says nothing about being IPS or not.

 

Not asking you to.

I thought we had previously established in this thread that Samsung doesn't make IPS panels.

And this site says that the LTN125AT01 is a TN panel.

So I still think the 4K screen for the Y50 will be TN.

 

Yeah Samsung's tech is called PLS. IPS is LG's thing.

Wouldn't be surprised if the 4K panel here is TN to keep costs down; I've already mentioned it several times in this thread. Someone said that it can't be TN because the viewing angles in the CES video look "too good" to be TN. Well believe it or not, there are TN panels with very good viewing angles (especially horizontally) that almost approach IPS/PLS/VA levels.
