Not much difference, just the sharpness.

Also, the higher resolution allows you to put 2 windows side by side which is very convenient when you are in need to do referencing.

1920x1080 resolution is kinda small (1920 / 2 = 960 pixels per window) not great for browsing or document reading.

Shimian can be purchased via group buy from LYN.
Lowyat Group Buy Shimian Monitor 2560x1440 resolution

you can contact Dell support at 1800 88 0022 regarding this issue . let us know if they do support 1to1 replacement for a dead pixel.

from what I have experienced, they send me a new monitor and later I send to them the one that had issues.

I call Dell. Dell send their delivery guy to my office. We swapped monitor. Done. Simple and easy

It will not look good in both gaming and office work if the monitor isn't set at its native resolution. It will not look decently sharp/crisp in the fonts and artwork.

It's still best to keep the Dell U2515H at its native resolution which is 2560x1440.
The moment you reduce the resolution, the fonts in IDE/Text-Editor/Browser and desktop-icons/images seems not sharp/crisp to the eyes.
The method I used to make it easy to the eyes is to set its font size in Windows Settings to 150%.
This way, I can read the words/fonts easily 2 or more arms away from the monitor without squinting my eyes.

For programming/video-rendering/photoshopping, I would recommend you to get at least 2560x1440, so you can have 2 tabs open to compare between classes (1 tab = 1280x1440 + 1280x1440).
With dual monitors at 2560x1440, you can use it to perform code referencing easily. 4 tabs open as shown in the review posted in the first page.

Below are some pictures taken with my phone of my Dell U2515H at 1 arm's length away (approximately 60 cm)

2048 x 1152 at 100% font size
This one is still too small for my eyes to comfortably read 1-2 arms away. Might be straining for some users.


2048 x 1152 at 125% font size
This one is still okay for my eyes to comfortably read 1-2 arms away. The fonts/images does not seem sharp.


2560 x 1440 at 100% font size
This one is still too small for my eyes to comfortably read 1-2 arms away (similar to 2048x1152 but even smaller). Might be straining for some users.


2560 x 1440 at 125% font size (similar to 2048 x1152 at 100%)
This one is still okay for my eyes to comfortably read 1 arms away. Fonts and images are super sharp/crisp.


2560 x 1440 at 150% font size (similar to 2048 x 1152 at 125%)
This one is superb for my eyes to comfortably read 2 or more arms away. Fonts and images are super sharp/crisp. Similar large font size like 2048 x 1152 at 125% but has the sharpness in it.

The one in the photoshot I have is Windows 10, and I have yet to experience those issues that you have mentioned above (overlapping images, menus, drop-down menus, etc).
What operating system are you currently using?

If you do not need the extra resolution of 2560x1440, you might want to go with 1920x1200 instead of 1920x1080 at 21-23-24 inch monitor since it will be quite helpful in programming-coding environment. Can read more lines of codes.


For my monitor, I did not use any professional calibration software or hardware, but manually tweaked accordingly according to my eyes comfort (like white background does not seem yellowish/grayish in text editor, etc). The fonts/text are pretty sharp after my 10~15 minutes manual calibration

Based on my experience, it's best to buy the best monitor that meets your needs first, then save up to a budget which you can afford.

If you do not need the extra I/O connections to the monitor and resolution workspace, then go for the U2415H.
This model also saves you some $$$ if you do not need those features from U2515H.

What monitor model you are currently using?
How many monitors you are using connected to your pc?
What is the monitor resolution and windows font size (100%, 125%, 150%) for each of the monitors ?

Will need to understand your situation, help answer the questions below:

Are you using Dell U2515H monitor?
Are you using more than 1 monitor? If yes, are all of the monitor Dell U2515H?
The monitor is connected via HDMI or Display Port?
Your monitor is connected to your desktop PC motherboard or PC graphic card or Laptop?

What windows operating system are you using?
Have you tried updating your graphic card driver?
If you try the monitor on another PC, does this issue occurs?

You could grab this monitor Dell U2515H (25 inch = RM1.4K) or a Dell U2715H (27 inch = RM2.1K).

They look the same in screenshot (regardless jpg/png/tiff) in Mspaint/Photoshop, but they definitely look different in my eyes when viewing in the monitor itself (2048x1152 is blurry, 2560x1440 is sharp)

I would recommend you to get the thinner bezel monitor because it will save some space with multi monitor placed close to one another. what other monitor you have on your purchase list apart from the u2515h?

thanks for your feedback
what monitor do you have in mind in your purchasing list?
have you already bought 1?

Regarding speakers in monitor or in TV, they do not sound really good from what I have experienced.
It lacks the sweet mellow highs and bass that a dedicated 2.1 speaker system can offer.
I would highly recommend to get a dedicated 2.1 speaker if you are listening music / watching movies / gaming.



I noticed that Dell speaker stand is amazingly good but it only comes in certain models such as the U series (U2515H ultra series).
Those stand allows you to perform 90 degrees rotation on both left/right (older models can only do from left).
And it's also height adjustable which is a plus for me! Previously I had to stacked multiple phone books to get to a specific height for my monitor.

Another alternative is to get a flexible stand (monitor arm) which allows you to position the monitor above your table (floating).
But it requires that the monitor supports vesa mount 100mm x 100mm.

The Dell U2515H IPS black is a little washed out (can be easily viewed when watching movies or dark scenes in it), but it's a small matter to me.
Truly black colors can be seen from TN Panels but those generate lots of heat especially in smaller rooms.
Also IPS monitor colors remains vivid when viewing in any angle horizontally. It does gray out when viewing at different heights (vertically).

So if I watch a movie with my family on my IPS panel, they don't complain about unable to view the color of the screen being washed out at different angle with same height.

I just did the experiment as shown in Asus on my Dell U2515H.
Basically it does not flicker at low brightness and contrast.
My monitor is set to blueish hue so it does not really matter to me as this custom mode I'm using does not fatigue my eyes.
Basically to avoid getting eye fatigue is to reduce the contrast and also use a matte screen (not glossy monitor!)
By setting those, you can easily protect your eyes.

I have yet to perform professional color calibration for the Dell U2515H.

Hence I could not advise you in this aspect since I have not experimented with having both the printed image from color printer matches the what-you-see-is-what-you-get from the Dell U2515H monitor.

BenQ BL2710PT bezels are pretty large and if you tried to place them close together, it will not look great
The U2713HM that I have has large bezels similarly to the BL2710PT and I find it distracting when switching screens + the monitor have to be further apart.
I would advise/recommend to get a dual 2560x1440 25" inch monitor (since the 27 inch takes up a considerable amount of space).

The other trend I'm seeing is people is going for 34 inch monitor Dell U3415W (3440x1440) and stack them vertically (so they can place the speaker beside the monitor).

Currently I'm using U2713HM (27 inch) and U2515H (25 inch). In my experience, they look identical in terms of the picture quality. However, the font's + icons + etc looks crispier (sharper) in the 25 inch. For long hours of reading, I set my monitor font size to roughly 150% (so a 2560x1440 will look like 2048x1536) but I could easily read the browser/pdf text from 6~7 feet away.

If money and desk space is a non-issue, I would go for the 27 inch, the fonts are much larger, easier to the eyes to read

Get the latest model U2715H instead of the older model such as U2713HM as they tend to generate more heat.
Newer models uses better LG panels.


Dell U2515H have a few modes you can choose as well as your custom one where you can set the RGB (Red Green Blue).
If it's too blue, you can set it less blue-ish.
Or purchase a monitor calibration hardware to setup the monitor color.
If you purchased monitor from IdealTech, they provide free monitor calibration.

Having 2 monitors provides better multi-tasking than a single monitor

Note: Also ensure that your computer motherboard has HDMI or DisplayPort that supports 2560x1400 native resolution, else you would not be able to experience the sharpness of the monitor.
The U2515H and U2715H does not come with any DVI or VGA input.

If you do programming, grab the one with 16:10 if you are going with smaller monitor resolution.
For 2560x1440 resolution, U2515H also works fine for computer programming, but 1920x1080 not comfortable (preferred if its 1920x1200).
