No display output from Raspberry Pi 3

Question

The Pi is connected to the power supply (5V 2000mA) and the HDMI is connected to monitor (1600 x 900). The status of my Pi is as follows:

Red light is solid
Green light blinks randomly
Ethernet port also seems to work (The light is blinking)

I'm not getting any output from my monitor. I have read the following:

I haven't had any luck even after reading these.

From the behaviour of your LEDs, it sounds like the Pi is booting normally. Couple of questions: Is the Pi accessible over SSH? Do you have access to a second display you can test the Pi with? — goobering, Mar 23 '16 at 14:09
As a quick test, hook it up to the TV. If it works the problem is specific to your monitor. If it doesn't there's likely a problem with the Pi's HDMI configuration. — goobering, Mar 23 '16 at 14:13

Change your settings in config.txt file in boot partition. Set:

hdmi_safe=0
hdmi_group=2
hdmi_mode=83

Reboot your device and check. This will set your HDMI output to 1600x900 with reduced blanking. For more information loot at: http://elinux.org/RPiconfig

Will unplugging my pi from the power supply damage it? – Rahul Mar 23 '16 at 14:14
No, you can feel free to unplug it. – Huczu Mar 23 '16 at 14:17
No luck It didn't work – Rahul Mar 23 '16 at 14:30
Tell more about your monitor. Model, refresh rate. – Huczu Mar 23 '16 at 14:32
It is a LG monitor with a refresh rate of 75Hz – Rahul Mar 23 '16 at 14:33
Try: hdmi_group=2 hdmi_mode=6 hdmi_force_hotplug=1 hdmi_ignore_edid=0xa5000080 config_hdmi_boost=4 disable_overscan=0 overscan_left=24 overscan_right=24 overscan_top=24 overscan_bottom=24 – Huczu Mar 23 '16 at 14:36
Not of any help – Rahul Mar 23 '16 at 14:45
Try to combine configuration related to your 75Hz refresh rate using this guide: http://elinux.org/RPiconfig – Huczu Mar 23 '16 at 14:46
The red light also blinks with the green one now – Rahul Mar 23 '16 at 14:49
A blinking red power LED indicates problems with the power supply. Check your connections, cable, and power supply. – Huczu Mar 23 '16 at 14:52

Incorrect! Don't ever unplug it without a proper shutdown. This can corrupt the SD card and possibly give you issues in the future. – Dylan Mar 23 '16 at 15:37
