So, i got a strange situation here. I have an old Asus ROG G751JM laptop connected to an old Samsung monitor (Model S20C301L) through a VGA connection.
This monitor supports both DVI-D and VGA inputs, while my laptop can output through VGA, HDMI or Thunderbolt/Mini DIsplayport. I wanted to upgrade to digital signal, so i bought an Thunderbolt/Mini DIsplayport to DVI cable.
At first, it was a nightmare. There was absolutely nothing i could do to get it to work. I spent hours troubleshooting, but the monitor just could not detect any signal, only VGA one. But then this happens.
I was testing with only one connection at once and i got tired of plugging and unplugging the cables every time. So i had the idea to keep both cables plugged in and change the source detection in monitor's menu when i wanted to. So, with the TB/MiniDP cable already connected, i've then connected the VGA cable (while DVI was selected as input source). The display started flashing. After 2 seconds, voilà, it was working. And i was like, "what the f***???" I've then unplugged the VGA cable, signal lost. Plugged it again, got digital signal.
Well, i'm happy that it's working now, but i simply don't understand what's happening here. Why is that i need both connections simultaneously to make it work? WIll that still happen if i use a HDMI to DVI cable?
Fun fact: the image displays only after windows startup. So, if i want to enter BIOS setup for example, i need to switch back to VGA as input source.
Sorry for my english.
Update: Can't run games with It, i get bsod.
(EXP GDC Beast v8.4d mPCI-E + GTX970 + ATX PSU) eGPU project for Lenovo IdeaPad Z710, i7-4700MQ, 16GB RAM, SSD, GeForce GT745MBy damianalex
I want to show you my new project.
I bought my laptop about 5 years ago. It was never speed deamon, but for every day use, it was enough to me.
Nvidia GeForce GT745M
512 SSD Adata SU800
Yesterday I bought Witcher 3. Of course on 1080p it's impossible to play, because of about 10fps
So I make a decision to buy external grahpic card.
I choose GTX970 and now I am looking for occasion to buy it.
I've already bought EXP GDC v8.4d mPCI-E. It is used and cost about 30$.
I will use ATX PSU to supply graphic card, because I have old desktop PSU at home.
1) unlock bios
2) buy GTX 970
3) enjoy Witcher 3!
BTW I try to cool down my laptop, so I replaced thermal paste to Kryonout Thermal Grizzly and make some tests. Temperatures and fps are on screenshots.
1) laptop on table, playing GTA V 1080p
- first minute (GPU core 1045MHz)
-after some time, because of high temperature and GPU throlttling (GPU core drop down even to 400MHz)
2) with thermalpad Glacier NC400 SilentiumPC
- 30 minute and longer (GPU core drop to about 900MHz)
3) without down case of laptop (like on picture with thermal paste) on thermalpad.
Here laptop never drops down MHz and max temp are about 72 Celsius degrees.
Bacause of that I bought second down case for my laptop and I will cut there additional holes.
I will describe next step when I get all stuff I need!
I created a case for egpu using 2.5mm acrylic sheets. The first time I created a case to support a GPU + ATX psu
Now I created another one for the GPU with an external Xbox 360 203w psu.
the finish was not good but for my use it is already good.
*both cases album
*Construction of the second case
*adapting xbox psu to 8pin power (taken from 24pin)
all made by hand with the tools I had.
I have recently acquired my Dell Inspiron 15 7000, and I am interested in building an egpu setup for it. It has a USB-C port. Any recommendations/guides out there?
