I am also wondering. But till now I still haven't seen any 4k lappies yet. Know any brands who has done it. would not mind going to Lowyat and kei poh with the demo sets there. At times its better looking at the real thing than just reading reviews.

I saw the samsung 4k tv sets in desa home a few months ago. Wow the picture was    even for a huge display.

Hello guys! I'm new here, and this is my first post.

I own a y510p and I have a few questions to ask.
1. Does anyone have a guide on how to clean the fan grill at the bottom? It looks pretty dusty but I have no idea how to access it.

2. I play alot of LoL, and it requires me to use the shift key alot. but recently it has been bugging me because the key doesn't register when I press it on the corner/edge, I have to press it in the center and it's really annoying, anyone experienced this or have a fix for it?

3. My space bar actually makes squeaky noises sometimes, is there a fix for this as well?

I do not own a smartphone and I normally use my laptop to listen to songs on the train. I put my laptop in the bag and when I got home, I realized that the plastic grill on my fan actually broke off from overheating! lol, just something for you guys to be aware about. Hope you guys can help me with my problem

Well

Basically a QHD screen in small size screen provides a very hIgh detail level. I use a personal term for easy understsnding: "Hardware Anti Antalizing which doesnt depend on VGA CARD POWER"

U no need look at y50 la. Why MBP retina graphic detail so nice? Its the higher dpi screen do the trick

2, 1 populated. depending on part number also have m2 or mSATA Slot for SSD. Crucial 240GB only RM499

Is the NVIDIA GT 720M inside the S410P good for modern games? Just looking for playable option, not high or ultra settings.

of course la, crucial dont have m2 in Malaysia yet. mine is mSATA in my Thinkpad T430, not Y510P just sayin' the price aint that expensive no more. 
Ultrabay can order from service center or any Lenovo Experience Store. m2 AFAIK, no one sells them in Malaysia.......(yet) God luck, mSATA though yes.
second hand? cause AFAIK the only brand new u series is the U430T, The only U410P that i can find comes with a GT610M graphics card and 3rd Gen i5, not 4th gen.
