      You're confusing things a bit - you have a HDMI to DVI cable (in-HDMI, out-DVI), but that's not so important.
      Can you post the /boot/config.txt configuration file ? It should be accessible either via SSH or by plugging the SD card into your PC (don't format the card if asked) as a boot partition.

        Hi, I copied the text from the config.text

        # For more options and information see
# http://rpf.io/configtxt
# Some settings may impact device functionality. See link above for details

# uncomment if you get no picture on HDMI for a default "safe" mode
#hdmi_safe=1

# uncomment this if your display has a black border of unused pixels visible
# and your display can output without overscan
#disable_overscan=1

# uncomment the following to adjust overscan. Use positive numbers if console
# goes off screen, and negative if there is too much border
#overscan_left=16
#overscan_right=16
#overscan_top=16
#overscan_bottom=16

# uncomment to force a console size. By default it will be display's size minus
# overscan.
#framebuffer_width=1280
#framebuffer_height=720

# uncomment if hdmi display is not detected and composite is being output
#hdmi_force_hotplug=1

# uncomment to force a specific HDMI mode (this will force VGA)
#hdmi_group=1
#hdmi_mode=1

# uncomment to force a HDMI mode rather than DVI. This can make audio work in
# DMT (computer monitor) modes
#hdmi_drive=2

# uncomment to increase signal to HDMI, if you have interference, blanking, or
# no display
#config_hdmi_boost=4

# uncomment for composite PAL
#sdtv_mode=2

#uncomment to overclock the arm. 700 MHz is the default.
#arm_freq=800

# Uncomment some or all of these to enable the optional hardware interfaces
#dtparam=i2c_arm=on
#dtparam=i2s=on
#dtparam=spi=on

# Uncomment this to enable the lirc-rpi module
#dtoverlay=lirc-rpi

# Additional overlays and parameters are documented /boot/overlays/README

# Enable audio (loads snd_bcm2835)
dtparam=audio=on
gpu_mem_256=128
gpu_mem_512=256
gpu_mem_1024=256
overscan_scale=1

        Thanks for the help

          Try un-commenting the line with config_hdmi_boost so it reads:

          config_hdmi_boost=4

          and see if you get an image when booting. Do you see the 4 raspberry showing up on boot ?

            Hi, tried that, see nothing on my screen, I get the digital Input message but when I turn on the pi, screen goes blank and nothing shows up but I can here sound coming from my speakers (speakers which is plugged in pi) but no picture

            thanks,

                Hi I don't have ssh enabled, watching a tutorial on how to do it. Since rasberry pi doen't connect to my dell, I have connected to my tv via HDMI/DVI cable and will get ssh enabled before connecting it back to my dell monitor using ssh

                  Hi, finally enabled SSH and installed WinSCP on my PC so my pi and PC showing same network. I switched my rasberry pi back to my dell monitor and have SSH ready to use

                  Going to be a noob here, how do I get the output?

                    You need to use Putty, not WinSCP, to run those commands.

                      Hi, thankfully I installed Putty before, finally got it working

                      
pi@retropie:~ $ tvservice -s
state 0x12000a [HDMI DMT (4) RGB full 4:3], 640x480 @ 60.00Hz, progressive
pi@retropie:~ $ tvservice -p
Powering on HDMI with preferred settings
pi@retropie:~ $

                      Thanks

                        @mitu Also, I connected my raspberry pi to my TV as it works but for some reason, no signal from my pi to the TV. Used the same cable as before but since the changes I made, tv is blank as well, no signal.

                        Regards,

                          @mumihp You can back-out the changes you've made (the config.txt modification), but I don't see how that would impact the TV image. The commands you ran are not changing any settings, they only probe and power up the display.
                          What version of RetroPie are you using ?

                              Looking at the specs of your monitor, it looks like the native resolution is 1280 x 1024. Try forcing this resolution by modifying the config.txt file with the video mode for this resolution - see https://www.raspberrypi.org/documentation/configuration/config-txt/video.md and look for hdmi_group and hdmi_mode.
                              Add also

                              hdmi_ignore_edid=0xa5000080
config_hdmi_boost=4

                              to those configuration and then try again to see if you get any video.

                                Hi, it seems my HDMI has stopped recognising anything. Since the changes, pi won't work on my tv or hdmi monitor (did before) so I basically did a fresh install of retropie. No matter what I do, I get the no signal on the tv/monitor. I don't understand if I did a fresh install, surely it my pi should be as I never changed anything so me connecting to the TV or my other monitor should work.

                                Honestly, it's frustrating, spents hours over the week, tryig to fix it after work. Worked great at first but now, nothing on anything. Atleast if it didn't work on my dell monitor, still could use it on my tv or other monitor but nothing now.

                                  Could it be that your cable or HDMI port are damaged ?

                                    Hi cable works fine, tested it with my other devices but nothing with rasberry pi. I don't know if it broke recently with me pulling it out often but decided to buy a new one, but will wait until the prices comes down, which it should since pi 4 came out recently.

                                    Anyway, thanks for the help.
