Question 1

i have macbook pro 15 retina late 2013. 
can i connect this monitor with thunderbolt? 
what about HDMI?

Accepted Answer

Mac thunderbolt ports also work as mini-displayport so you can connect any monitor via  thunderbolt port using a mini-displayport to displayport/dvi/dual dvi/hdmi cable.  It has to be a thunderbolt port directly from the device or at the end of a thunderbolt chain that does not include another display (you can't chain displays).

This monitor comes with a mini-displayport to displayport cable to connect the monitor and that works fine with thunderbolt ports.

Question 2

Does this monitor come with the required Service Tag Number for registering the Dell (Manufacturers) 3 year warranty?

Accepted Answer

No. And getting warranty support is a PITA. You may need to call several times to get someone who is patient enough to help you without a service tag. I ended up sending them a picture of the serial number before they were able to help me. You'll have to search for the Dell support article titled "Monitor warranties and replacement instructions " to get support.

Question 3

Can this be mounted?

Accepted Answer

Yes, as it says in the description "The U2515H is VESA-compatible, so you can wall mount your monitor..."

However the base is really high quality, and is most likely somewhat responsible for the higher cost of the monitor. In my opinion it would be a shame to buy it just to remove the base. But nonetheless, it will definitely mount to anything with VESA (100 mm).

Question 4

I just bought two of these and my desktop layout won't stay in place.  It seems as if the display will shrink if I've not been using the monitor for awhile, or randomly does anybody know how to stop this?  Any help is great appreciated.

Accepted Answer

On the bottom bezel there is a power button and four small dots that are buttons. I need to shine a flashlight on mine to see them well.  From the power button moving left, skip the first dot and tap the 2nd dot.  Four little icons should pop up on the screen. Above the 2nd dot should be a box with lines through it. Tap the 2nd dot again.  This is the settings menu. Use the dots that show an up or down icon above them to move the menu to the "Display" setting. It should show 16:9. You can arrow down to "Others" and arrow over to Factory reset if you just want to get it back to the way you bought it.

Of course your problem might not be with the monitor, it could very well be an issue with your Display settings on your computer or your graphics card and how they are interacting. If you are using a dual or more monitor setup and you turn one monitor off this can happen as the Operating system adjusts.

Question 5

How many hz does this monitor have?

Accepted Answer

It's a 60hz moniitor

Question 6

What cords, cables, cd's etc. come with this monitor?

Accepted Answer

Power cable, Displayport (mini-DP  DP) cable, and USB3.0 cable are included.

Question 7

It's not very common to have two options for response times as the faster one (6ms) would always be used, unless there are drawbacks/restrictions because of it.  Is any aspect of the monitor hindered by using 6ms over 8ms?

Accepted Answer

Absolutely not. Unless you are doing some really wild gaming with it, I doubt you will ever notice any difference. I have two of these and do anything from office work to flight sim on them with no problem at all. I purchased them to replace a couple of old 2405's that just wore out and have been extremely happy with them. I don't think you can go wrong with these monitors.

Question 8

WHAT IS THE LENGTH AND HEIGHT OF THE U2515H25?

Accepted Answer

It sucks that the specifications section doesn't have this info... Oh wait.
