Tl;dr -- Monitor worked with laptop first time just fine, I disconnected the laptop the next morning for work and tried using it again later that night, monitor just displays 'no signal' now.

Hi all, I just purchased a new monitor (Acer H236HL) and I followed the instructions provided in the manual for hooking it up to my laptop. Worked beautifully the very first time. I disconnected the laptop to take it to work with me.
The next day, I tried connecting the laptop to the monitor again, and no matter what I try (disconnecting everything and following the instructions on the manual again), the monitor just displays 'No signal' and goes back to power-saving mode. My laptop also doesn't detect a second monitor.
The monitor hasn't been moved once since yesterday, and when I unhooked the laptop from the monitor the first time last night, I just removed the HDMI cable from the laptop while the monitor was powered off. Interestingly enough, even when my monitor gets no signal from my laptop, if I unhook the HDMI while the monitor is in power-saving mode, the monitor immediately displays that the cable has been unplugged -- so it's able to tell that there IS a cable, I suppose it's just that my laptop isn't communicating with the monitor. Weird since nothing has happened to my laptop.
Can anyone provide any input (hahaha.. T_T) as to what's going on? Thanks!
Edit: Just borrowed a VGA cable from my neighbor, and surprisingly it works on that cable..

Leader BoardWhat's this?
HDMI is the standard for connecting components in a home theater setup, including TVs, video projectors, Ultra HD and Blu-ray Disc players, receivers, media streamers, and even cable/satellite boxes.
Copy-Protection and the HDMI Handshake
One purpose of HDMI is to make it easier to connect all your components together by using one cable for both audio and video. However, another purpose is to ensure copy-protection (known as HDCP and for 4K HDCP 2.2). This copy protection standard requires that HDMI connected components be able to recognize and communicate with each other.
This ability to recognize and communicate is referred to as the HDMI handshake. If the 'handshake' doesn't work, the HDCP encryption embedded in the HDMI signal is not recognized properly by one, or more, of the connected components. This most often results in you not being able to see a picture on a TV screen and possibly not hear any sound through the TV.
When an HDMI connection goes wrong, there are some things you can do that will, in most cases, fix it.
HDMI Troubleshooting Tips
Here are some steps that may help correct HDMI connection problems so you can get back to watching TV.
The HDR Factor
Can diablo 2 run on windows 10 2. The implementation of HDR on many 4K Ultra HD TVs may also cause HDMI connection glitches.
If you have an HDR-enabled source device, such as a UHD Blu-ray Disc player or Media Streamer connected to an HDR-compatible TV/Video projector and are attempting to access HDR-encoded content, the TV/Video Projector may not always recognize it.
When an HDR TV or Video Projector detects an HDR signal, a brief confirmation indicator should appear on the top left or right corner of the screen.
If you do not see an HDR indicator, but see a displayed message by the TV or source component that you need to connect the HDR source to an HDR-compatible TV or a message that states the incoming signal has been downgraded to 1080p due to the lack of HDR detection, you may still be able to correct this issue.
The reason this occurs is that the firmware of the TV/Video projector may not be reading the HDR signal correctly in the AUTO setting, so changing the source device's setting to 4K may correct the problem. Make sure the TV/Video Projector has the most recent firmware update.
Acer Hdmi DriverTroubleshooting HDMI-to-DVI or DVI-to-HDMI Connection Problems
Another HDMI connection issue sometimes arises when it is necessary to connect an HDMI-enabled device to a TV or monitor that has a DVI connection, or a DVI-enabled source device to an HDMI-equipped TV.
In this case, you need to use an HDMI-to-DVI conversion cable (HDMI on one end – DVI on the other) or use an HDMI cable with an added HDMI-to-DVI adapter or a DVI cable with a DVI-to-HDMI adapter.
The added requirement is that the DVI-equipped device you are connecting is HDCP-enabled. This allows the communication between both the HDMI and DVI devices.
Although HDMI can pass both video and audio signals, DVI connections can only pass video signals. This means if you connect an HDMI source component to a DVI equipped TV, you have to make a separate connection to access audio. Depending on the TV, this may be done either via RCA or 3.5mm audio connection.
Ordinarily, there should not be a problem converting HDMI to DVI, but there can be. For example, 3D and 4K signals are not compatible. Dialogue of tiger zinda hai in written story. With standard 480p, 720p, or 1080p resolution video signals, most of the time this is successful, but some adapters and conversion cables don't work as advertised. If you encounter this problem, it may not necessarily be the TV or another component. You may have to try a couple of different branded adapters or cables.
Older-DVI equipped TVs, even if they are HDCP compliant, may not have the proper firmware to recognize the identity of the HDMI source component you are trying to connect. If you run into this situation a call to tech support for your TV or source component is a good idea before proceeding further.
Connecting Your PC/Laptop to a TV Using HDMI
With more consumers using their PC or Laptop as a home theater source component, problems can arise that may prevent you from seeing a picture when trying to connect an HDMI-equipped PC/Laptop to an HDMI-equipped TV.
Make sure that you go into your PC/Laptop settings and designate HDMI as the default output connection. If you can't get an image from your laptop to show up on your TV screen, try the following:
If you are unsuccessful connecting your PC to your TV using an HDMI cable, if the TV has a VGA input, you may have to use that instead.
HDMI Without Cables
Another form of HDMI connectivity is 'Wireless HDMI.' This is most commonly done by an HDMI cable coming out of a source device (Blu-ray Player, Media Streamer, Cable/Satellite Box) to an external transmitter that sends the audio/video signal wirelessly to a receiver, that, in turn, is connected to a TV or video projector using a short HDMI cable.
There are two main 'wireless HDMI' formats, each supporting their own group of products: WHDI and Wireless HD (WiHD).
These options are intended to make it more convenient to connect HDMI sources and displays without an unsightly HDMI cable (especially if your TV or video projector is across the room).
However, just as with traditional wired HDMI connectivity, there can be 'quirks' such as distance, line-of-site issues, and interference (depending on whether you are using WHDI or WiHD).
There are also differences on how each method may be implemented on a brand and model level, such as whether some surround sound formats and 3D can be accommodated, and many 'wireless HDMI' transmitters/receivers are not 4K compatible – be sure to check wireless HDMI product specifications.
If you install a 'wireless HDMI' connection option and find that it is isn't working properly, the first thing to do is try changing the position, distance, and component turn-on sequence and see if that solves the problem.
If you find that following those setup that issue cannot be resolved, contact Tech Support for your specific 'wireless HDMI' connection product.
If that doesn't solve the problem, the 'stability' of a traditionally wired HDMI connection setup might work best for you. For long distances, there are also additional HDMI connection options to consider.
The Bottom Line
Love it or hate it, HDMI is the default interface used for connecting home theater components together. It was originally designed to provide a single, convenient, connection for both audio and video, with built-in copy-protection and the added ability to be upgraded over time.
However, due to the fact that both the source and display devices have to communicate and recognize each other and encoded content has to be properly detected, glitches can occur which may prevent you from seeing a picture and/or hearing sound.
Following the practical steps outlined above can solve most HDMI connection issues.

HDMI technology incorporates both video and audio through the same cable without the need for an additional audio connection. This differs from the VGA and DVI formats, which only allow video and require a direct connection from your audio card to the Acer monitor’s audio inputs. Although HDMI allows integrated audio, the audio portion may not be enabled by default on your computer, so a direct connection may not work at first. However, a few system tweaks will allow a functional, single-cable connection between your PC and your Acer monitor.
