Here's an image of how the game looks on 1920x1080. I'll go over what you need for that and another useful mod to allow for a little bit more lenient gameplay (ability to respec stats and skills anytime free).
First off, this is not able to be played online (Closed Battle.net). Don't try it you'll get banned so hard. You want to relive Diablo 2 in your freetime before D3 ROS takes over your life?
You're going to need four things. You'll need Diablo 2 and Lord of Destruction. • PlugY () this is the free-respec, free-reskill and infinite storage/cross character storage mod.
It also brings to the table every runeword from Battle.net (ladder-only runewords) and the Uber Diablo event from selling SOJs. • MultiRes () this is the Resolution hack/plugin. It allows you to use up to 1920x1080 resolution in Diablo 2. IT IS NOT ALLOWED ONLINE AND IS A BANNABLE MODIFICATION. • Borderless Gaming () Very useful app, allows you to remove the border to your window on Diablo 2, allowing for full screen 'windowed' gameplay. Now for the installation of all these crazy things.
• Install Diablo 2. It should be at patch 1.12a.
This is what we want, do not update it. • Install PlugY by running the executable, no need to change any settings. • Unzip MultiRes.zip's content into your Diablo II folder. • Inside your Diablo II folder should be a folder named 'Mod PlugY'. Open that up and find the PlugY config file. You'll see DllToLoad under the [GENERAL] section.
Add D2MultiRes.dll to that and save the file. [GENERAL] ActivePlugin=1 DisableBattleNet=1 ActiveLogFile=0 DllToLoad=D2MultiRes.dll.
Playing Diablo 2 Again? Install Diablo 2. It should be at patch 1.12a. Most likely requires LOD to be installed.
