The display resolution is dependant on your hardware and drivers. I don't think it depends on the OS installed. If your GPU or the inbuilt display adapter is able to give you support a 4k output, you can easily connect it to the new generation 4k LCD/LEDs.
What is the display resolution of the 28-inch display that you've seen on Flipkart? It should most probably be a full HD 1920 X 1080 display. If it is, then these days all CPU/GPU/Motherboards support this resolution and there shouldn't be any issue. However, if it is a 4k display, then you would need to install a high-powered graphics card.
I have personally connected my laptop, which has a standard display of 1366 X 768 to larger LED TVs with a resolution of upto 3840x2160 without any issues.
