Y50 Thread

Do you have a source that for that information because I'm looking forward to that model and if it's not released before mid July I'm just going for the 4k 512ssd.

 

Are shipping times OK now? Or is Lenovo still baiting few a few days and switching to 3-4 weeks again?

 

it was never ok, you only know when you try it out...

 

for gaming, yeah it should be fine. y50's cooling is arguably bad, but bad is a comparative measurement. if you compare it to AW or asus g750 series it's bad, but if you compare it to notebooks with similar price/performance/size it's average or even above average

 

Can someone help me with this. I installed the 338 tried running it, denied as expected. Downloaded the other file and replaced the NVLTi.txt in the display driver folder with it. I believe I disabled driver signing, made it all the way through the steps without any issues. Rebooted it and got the same error again. To I have to delete the old driver folder and where would I find that? Thanks

 

what error? can you post screenshots of the error and your display.driver folder? btw if you install anything starting 340.43 you don't need this anymore

 

Finally got it, just kept doing the same thing till it worked haha. The point of updating the drivers was because every time I go full screen in steam my screen flickers terribly. Unfortunately this didn't seem to fix the problem. Completely disabling the 860m in device manager, but obviously i need the 860 to play games... anyone else experiencing this and know how I can fix it?

 

oh ok good, initially I thought it was gonna be another problem with inf extension :thumbsup:

 

Do you happen to know about the flickering screen issue I have?

Side note: not a fan of this keyboard. Too light and clicky and missed keystrokes when my finger hits the casing yet still fully depresses the key. Too bad it isn't like my Dell preision laptop I use for work. Now that is a good keyboard!

 

Well.. its probably called dell 'precision' for something

wow, the 4K panel has a refresh rate @ 48Hz

 

So is it a good thing or a bad thing?

 

what?! only 48hz?! tell me this is just a rumor! :O

 

the screen is limited to 48 fps :O

 

uh when will this thing be available in europe? still nothing on ebay germany/austria.

 

Source?

Or just rumor?

 

48Hz on a 4K is standard on almost all 4K displays.

 

Where did you get that info? Even so, I doubt it will be limited to that refresh rate at lower resolutions. It's not like anyone will be gaming in 4k above 48fps

 

48Hz refresh rate

That's what I'm wondering. I won't care if its limited to that in 4k. It will be a problem if I'm limited to 48 FPS if I'm downscaling though...

 

Same. The only reason I didn't buy the non 4k version was because of the screen, and now if the 4k limits to 48 FPS i'm definitely not gonna buy it..

 

Really? I definitely cannot buy the 4k model if its limited to 48 FPS, any decent first person shooter is useless below 60 FPS, but then are gaming frames per second what we are talking about here?

 

You can hardly play any next-gen first person shooting games(like BF4) @ 4K while having 30+ fps, trust me.
But at least 48Hz is better than 30Hz, not so bad as you thought.

 

The thing we are wondering about is if it runs at 60 hz if downscaled to 1080p or perhaps some other resolution. I don't think anyone expects 48 fps on 4k with an 860m on any decently new game.

 

So its not a screen limitation? We can reduce the resolution to 1080p and be able to get high framerates?

 

48hz is just a standard like Brian said before. All modern laptops these days use embedded displayport which supports 4k up to 60hz so what is there to worry about? eDP is also what amd is using for its active sync to match against nvidia's g sync because of its capability to support variable refresh rate and amd certainly isn't pathetic enough to select something that doesn't support 60hz. Simply adjust it to 60hz if you don't like it. As belatedeffort has mentioned before, I would worry about getting games to run above 30fps first before freaking out pver refresh rate here

 

So I got the 4k model today. Good news - the screen is phenomenal! It might be the nicest screen I've ever seen. The viewing angles are as good as I'd ever hope for and the colors really pop out. I calibrated it and got really good numbers, typical of a great IPS/PLS screen: 97% sRGB, 71% NTSC and 75% aRGB. The screen model is SDC4852 if anyone cares.

I can say without a doubt that this display is MUCH better than the Razer Blade. The viewing angles are superior. The colors are about the same but the Y50 doesn't suffer from the glow and weird color shifting that the Razer Blade had. I also did my own test which the Y50 passed. It sounds stupid but I just open FTL to the title menu and drag the window and see if the colors of the background shift. I'm not sure why but some displays have a horrible blur effect when doing this. The Razer Blade looked pretty bad with that test but the Y50 looked perfect. Maybe someone can educate me on what it's actually testing(ghosting, motion blur, etc?)

There is one fatal flaw though - The refresh rate is locked at 48fps. I've been trying to figure out how to change it but laptops usually have that locked down pretty tight. It's not as easy of a fix (like just using CRU on a desktop) because Optimus is installed for graphics switching. I was hoping that lowering the resolution would allow more bandwidth but it doesn't. That makes no sense to me whatsoever. Intel locked most custom resolutions too so I couldn't add it as an option. 1920x1080 is a resolution they give you, but like the Razer Blade, there is no middle option. I was really hoping for 2560x1440 but it isn't available.

I took some video of the difference between the touch non 4k model and the 4k model. I wasn't able to get them side by side because of the timing of my friend's return. I did put my other laptop(Q550LF) next to both of them for a comparison. You can easily see the difference in display quality even without my other laptop there. I still think Lenovo really dropped the ball on the FHD models.

Edit: I forgot to mention that I did have some minor backlight bleed in the corners and bottom edge. It's definitely not bad at all but it's still there. IPS and PLS screens almost always have this issue. I've seen way worse on other laptops, so it's not anything to worry about. The worst of it is on the bottom edge but is only noticeable in a dark room with a back screen.

 

Another thing to note: To test response time, I go by feel. I know there's an official way to do it by taking pictures with a DSLR but I don't care for the actual numbers. I just do a side by side test with the Skyrim main menu with a G700s wireless mouse. If there is a significant delay in response time, it's very noticeable. My desktop has 6ms response time so I compare it directly with that. That said, the y50 has a noticeable delay in response time but it's not too bad. The TN screen on the FHD version was actually better than my desktop I think(naturally since it's TN). The 4k Y50 feels better than the Q550LF, if that means anything to anyone but it was worse than my desktop. Really it's pretty decent for IPS, but could be better. It would be nice to know the actual number on the spec sheet but it would take some digging. I think people who use fps a lot are going to have a tough time with the response time AND the 48fps cap.

FWIW, Skyrim capped the 48 fps on ultra with AA off in FHD. In full res it barely broke 20fps had had some bugs like text floating in the middle of the screen. Looked the same in both res anyways, so no reason to go that high.

 

Could we upgrade the refresh rate if we downscale the resolution? I would like to use UHD version in 4k for design, but in 2k for gaming. I don't want UHD version to stuck at 48 fps in gaming. Does anyone can clarify it?

 

Good information I'm planning on buying (would you recommend?), please keep us updated and of you find out a way to break the 48hz let me know. Thanks.

 

could you share any video with playing any recent game such as bf4 including the fps count at the corner? we are going to have much better idea about it. thanks

It's locked. I've tried to overclock laptop displays before and have never been successful. If anyone knows a reasonable way to do it, let me know. From my experience, it's all controlled by Intel and you only get what they let you control. If it wasn't Optimus, it would be possible. Someone please prove me wrong.

 

I don't have bf4. I have b43 though. I doubt it will be any different than the FHD version in terms of framerates besides the cap. UHD will be slow and unplayable unless on medium settings probably

 

How's the battery life on the 4k? Also, have you run into any problems with scaling?

 

Well it looks like the gentlemen above was not able to break the 48FPS cap even while reducing the resolution. 48 FPS on any first person shooter is a big bottleneck.

For anyone interested in playing games at 60 fps plus I guess there is no way to do this even if you lower the to FHD?

If I can't play even current games such as battlefield at 60 fps in FHD resolution then I sure won't be buying this "gaming" laptop for 1500 plus. Really do wish the FHD screens were better, that would have been perfect.

 

Scaling is the same as other 4k laptops. It comes perfectly scaled. If you switch the desktop to a lower res, everything is huge and barely usable. You would have to rescale everything to get it to look right at a lower res. Games scale to 1080p good and look fine. As with the Razer Blade, I suspect that some games will still switch to letterbox even if scaled, which would require you to manually change the desktop res. I haven't played with many games yet, so I don't know for certain. Some apps and installers have unfixable text scaling issues. We can only hope the devs will fix their own issues sometime soon.

I also haven't had it long enough for the battery yet, but I'll do a rundown tonight sometime if I get a chance.

 

Wow, if the 4k model really is capped at 48 fps then I will be looking for a new laptop. Really disappointing.

 

So what you are saying is that it's not really Lenovo's fault for an inferior product, but rather that it's the result of using Optimus?

 

Did it take significant calibrations to reach those %s? I don't have a colorimeter so I probably won't be able to do a professional calibration.

That said, if I cannot, through any means possible, reach 60 fps on the 4k screen even scaled to 1080p, then that absolutely is a dealbreaker

 

really? I don't think nvidia lies to us that often

Custom Resolutions | NVIDIA

@xentar
go to graphics properties and create a custom res, leaving everything the same except set to whatever refresh rate you want. this should be the EASIEST way if it works. please try and tell us if it works

"Go into your graphics properties, screen resolution and create a custom resolution. Leave all the settings as is except change refresh rate to whatever you want. If you push it to far, nothing will display and it will revert back to old settings. This happens for me a 75Hz. I can run at 74Hz but I run at 72Hz as it is more stable.

Note, I did this on a old screen that I don't care about. It has been like this for a long time now (6 months) but I still would do it on really expensive screen. It will have its long lasting effects eventually"

OR you can try something called EVGA Pixel Clock OC which is also a very good option

 

I don't know if it is right place to ask, but is there any 4k laptop with at least 60 Mhz refresh rates?

 

Anyone know of any compatible high color gamut screens to replace the one in the Y50?

 

Also, I'm confused about the screen model-on the hardware manuel it lists the UHD screen as LTN-*some random numbers*. I dont recall seeing an SDC anywhere on there, and it only listed one UHD panel

EDIT: Nvm double checked and the panel is supposed to SDC LTN*random numbers* so it should be the right one I'm guessing

 

I'm litlle confused. Is it worth of buying in terms of gaming and cooling? What is an alternative in its class - better coolig and performance?

 

Can someone help me decide between the Y50 and Asus G551? I don't want to spend 1600 on the Y50 only to regret it later..

 

it's worth it. alternative are either more expensive or inferior in cooling

 

^ For me it would depend on price, and since we dont know g551 price its very hard to compare. However, if there is a way for the Y50 4k version to reach 60hz refresh rate somehow, I'm fairly confident the top end 4k model will be the most bang for buck out there. On the other hand, if the screen is stuck at 48hz even when downscaling to 1080p and heibks idea above doesn't work, I would not reccomend it to anyone whose primary focus is gaming because capping at 48 fps sucks. Bad. If that is the case, I would wait for the G551 and if that doesn't work even look at other options.

 

this is a video showing how to create a custom res, but the point is not to create custom res
WHEN YOU ARE CREATING IT, LEAVE THE RES AS 4K BUT JACK UP THE REFRESH RATE

@Xentar try and see if this works, if not then you can try EVGA Pixel Clock OC

 

No, it was Lenovo's. The screen is limited because of the panel they chose but we're not allowed to OC it because it uses Optimus and Intel's drivers are harder to manipulate than Nvidia's. For us to be able to use custom resolutions and refresh rates, Intel would have to give us permission. As of now, any custom resolution I try to enter results in an error telling me that I don't have enough bandwidth. Since I know 1920x1080 @ 30 Hz is less bandwidth than the default 48Hz, I can only assume they locked us out of adjusting anything. I'm not sure if there are any 60Hz 4k panels out there. Razer's was 3200x1800 and it was 60Hz. I'm sure most fps gamers would have preferred that res in 15.6" form if it meant 60fps.
