Just purchased an Inspiron 3847 desktop with integrated graphics to evaluate if we should get them for our company. Connected an ASUS monitor via HDMI and did not get video. Could not figure out what was going on so connected via VGA instead and it worked as expected. Ultimately determined that the Inspiron is not sending a wake up signal to the monitor. Tried the monitor on a different model computer and it worked correctly. Tried a different HDMI cable with the monitor and the Inspiron but no change. So it means that using an HDMI monitor on the Inspiron 3847 one has to turn on the monitor after the computer is started in order for it to connect via HDMI. Checked to see if there was a BIOS update but I have version 2 that was just recently released. Any suggestions on how to make the Inspiron wake up the monitor when the system is powered on or taken out of sleep mode?
Well thanks for all who may have looked but could not think of a solution. This system will just go back. If it can't wake up an HDMI monitor then it is of no use to us. Dell support blamed the monitor and ASUS blames the HDMI card noting that the issue occurs before the system even boots... meaning it is a fundamental hardware issue. Perhaps Dell will fix it with the next BIOS update. Unfortunately for Dell I don't want to be a beta tester for Dell's new desktop.
Thought I would try contacting technical support again... but just wasted more time.
No suggestions were made whatsoever.
Only said 'since it is an out of box issue to contact customer support.'
I have contacted customer support via the email request for to return the system.
Dell computer fail. Dell technical support fail. Dell forum fail. Dell technical support fail again.

Three days later and no response from dell after completing the form on dell.com to request to return this machine.
I did receive an email confirmation staying that they would contact me in 24 hours But nothing since.
is this a new way for Dell to make a bad situation worse?
Does anyone have a suggestion on how to proceed other than calling my credit card company to dispute the charge?
Thank you for taking your time to write up about Dimension 3947's problem.
I have the same system for about two months and have been using the VGA cable all this time.
I am in the process of switching to HDMI cable and you have save me some time with
the DELL support.
In fairness you won't get anywhere talking to people like you do.
I had the same problem, but fortunately got better help from Dell than Cathaleen did. I just purchased an Inspiron 3847 desktop from Dell, and also bought a brand new ASUS monitor from amazon. Worked fine with the VGA cable, but didn't work with the HDMI cable. The solution is actually simple, and you only have to do it once and you'll be good to go. Basically, you need to switch the monitor to HDMI input while it's on the VGA cable. Then remove the VGA cable and install the HDMI cable. Here's how to do this: 1.hook your desktop to the monitor with the VGA cable. 2. Punch the "menu" button on the ASUS monitor. 3. Scroll down to "Input Select" using the "down" button on the monitor (just to the left of the menu button). 4. Punch the menu button to move over to the list of cables 5. Scroll down to select HDMI. 5. Remove the VGA cable, and install the HDMI cable.
I just purchased this same system (Inspiron 3847), bought a Dell S2415H Monitor and used included HDMI cable. Same issue. Are you kidding me? C'mon dell...this doesn't work even with your own equipment!
I see the workaround above and will attempt this, but what happens after a power outage, or being unplugged. I cannot have non-tech folks trying to figure out why their monitor won't work.
I bought this strictly so that I could use HDMI, not so that I would need to revert to VGA input.
Not sure if this will work for others, but I've had some luck turning off hibernation altogether. This was done at an elevated command prompt-
type in: powercfg.exe /hibernate off
After hibernation was disabled, at least the screen will wake after turning off. My other power options are set to maximum performance, with monitor going off after about 30 minutes. I will be leaving machine alone for a few hours, we will see if this works.
I don't know what you're all talking about here. I use an Asus PB238Q monitor with my Dell, though not with an Inspiron 3847.
This monitor, and probably most / all Asus monitors, has an on-screen display (OSD) that's totally independent of video input from the PC.
I selected the input source (choice of VGA, DVI, DP, HDMI) using the OSD before it was ever even connected to the PC. And I turn off both PC and monitor at a power strip at night, but monitor still remembers exactly what input source was selected.
Doesn't anybody ever read the instructions?
This whole thread sounds like User Error! and a big bugaboo entirely about a whole lot of nothing.

I am NOT a Dell employee
I hate to break it to you, but I spent an entire day working on this issue. Uninstalled monitor, selected HDMI from Dell OSD (mentioned above), reinstalled graphic driver, changed HDMI cables, check BIOS settings, etc. I've been an IT tech for 20 years....it's not difficult to tell when something doesn't work as it should.
From the factory the computer default is to go into hibernate sleep, even after changing power config settings. When the monitor goes off say after 30 minutes, my HDMI monitor (Dell S2415H) does not wake as it should- It seems this is an issue others have had as well.
I turn hibernate on...the monitor doesn't wake from sleep....I turn hibernate off...the monitor wakes from sleep. This is an issue with either Dell's power config settings, graphic driver issue, or the monitor....Not user error.
I have 5 of these systems going into the hands of folks who do not work in IT for a living...if their monitor doesn't work all day, every day, then I'm going to waste my time on something that should have worked from day 1. A workaround is just that, it's not a fix. It needs to be reliable.
I have been having the exact sane issue with my 1 day old inspiron 3847, so it stands that the issue still has not been fixed. I will try to update the video drivers with the latest update and will update this post if it has any effect. Pretty sad that this issue still had not been fixed after so MANY months.
Found the solution (that works for me at least. 1. Restart your computer 2. Press F12 when presented with the option. 3. Enter your bios screen and navigate to the advanced tab. 4. Enable multimonitor support. Done!
Good to know,since I just bought an AOC 12369Vm monitor /w 2 hdmi,dvi and D-sub(VGA)...and just ordered a 3847(and after reading some of the other posts about only having a 300 W PSU,limited GPU upgrades,,including this thread.I'm wondering about that.).
