League of Legends Client Black Screen Fix (2026): Loading Screen, Riot Client and In Game Steps

The fix for a League of Legends black screen depends on where it goes black.

If champ select ends, the match window opens and you get a black screen instead of the loading screen, Riot's October 22, 2026 article Black Screen Instead of Loading Screen in League of Legends is the closest match, and its order is: check minimum specs, use your dedicated GPU, update graphics drivers, clean reinstall the driver with DDU, configure your firewall, clean boot, repair, reinstall.

If the Riot Client window is black before you ever reach a match, the Riot Client FAQ comes first: restart Riot Client, confirm it is fully updated, restart your PC.

This guide covers a black client, loading screen or game window on a Windows PC, not performance tuning like League of Legends FPS boost settings and not a black screen that shows up while recording. Everything reflects Riot's support pages as checked on November 12, 2026.

Symptoms, the matching official document, and the first move

The short answer and when to contact Riot

Here is the short version: first pin down when the screen goes black. Black instead of the loading screen means dedicated GPU plus a driver update. Black partway through a match means Riot's Black Screen During Game order, which adds Windows updates and returning overclocked parts to stock.

A black Riot Client window means restart Riot Client and confirm it fully updated. Since 2026, every Riot PC game launches through Riot Client, so a desktop shortcut opening the game page inside Riot Client first is normal.

Launch failures, blank screens and repeated launch attempts are not expected behavior, and Riot asks you to check service status and then contact Player Support. If the client opens fine and the problem is delay, lowering your LoL ping is the better fit.

Step-by-step fixes in order

1. 1Restart Riot Client, confirm the update, restart the PC, check service statusFully close Riot Client, open it again and make sure the update finished. Then restart the PC and launch the game from Riot Client again. A restart closes temporary processes and clears memory so the game starts from a clean state, which is why Riot's docs put it near the top. If nothing changes, check the Riot Service Status page for a known issue in your region. Confirm whether this fixed it before moving on, so you can narrow down the cause.
2. 2Switch to your dedicated GPU and update the driverOn a laptop or any PC with both integrated and dedicated graphics, open Windows Settings > System > Display > Graphics, find League of Legends, click Options, choose High performance, save and restart the game. If the game is not listed, add its exe from the install folder on the same page. The full walkthrough is in how to choose which GPU a game uses. Next, press Windows key+R, run dxdiag and read the card name and maker on the Display tab, update the driver with the AMD, NVIDIA or Intel tool, and restart. Riot notes that outdated drivers can cause crashes, freezes and black screens.
3. 3Clean reinstall with DDU, undo overclocks, update WindowsIf a fresh driver does not help, leftovers from the old one may still be in the way, so Riot's loading screen article says to remove it with Display Driver Uninstaller (DDU) and install it again. The article for a screen that goes black mid match adds two steps: install pending Windows updates, which include DirectX, and temporarily return overclocked hardware to stock settings. The loading screen article starts with a minimum spec check, so compare your PC against League of Legends system requirements or Riot's own requirements page.
4. 4Run the Riot Client full repair toolSign in to Riot Client, open the Profile Icon at the top right, choose Settings, select the game, and click Repair, then follow the prompts. The tool restores missing or corrupted files. If the repair itself fails, restart the PC and try again, use a wired connection if you can, confirm at least 8GB of free disk space, check Task Manager for leftover League processes, and make sure League is not running under another Windows user. Riot's guide then points to chkdsk for the drive and Windows Memory Diagnostic for RAM.
5. 5Use a clean boot to separate the causePress Windows key+R, run msconfig, open the Services tab, and make sure Hide all Microsoft services is checked before you click Disable All. Find vgc in the list and tick it again, click Apply and OK, then restart. This is a test state to see whether another program is involved. Security software such as antivirus can stay active in this state, so the next step may still be needed.
6. 6Add security software exceptions and check compatibility modeRiot's document for a loading screen that never starts after champion select tells you to add these files as exceptions in your security software: LeagueClient.exe, LeagueClientUx.exe, LeagueClientUxRenderer.exe, League of Legends.exe, RiotClientServices.exe, vgc.exe and vgm.exe. Disable third-party antivirus only briefly as a test, and read Riot's connection troubleshooting guide before touching the firewall. The same document says to right-click the game exe, open Properties, and turn compatibility mode off. The older client-disappears guide instead suggests Run as Administrator on the shortcut and syncing the Windows clock with Update now.
7. 7Lower graphics settings, reinstall, send logsIf the game window shows up even briefly, set video settings to the lowest level from the Settings gear and raise them step by step, and reset NVIDIA Control Panel or AMD Software to defaults. If it still happens after every step, reinstall the game; the launching errors article also says to uninstall Vanguard, reinstall and restart the PC. The final step in Riot's October 2026 articles is to gather logs with the Riot Repair Tool and attach them to a Player Support ticket. If you see a Something unusual happened message, there is a separate official article that involves registry edits, so read it before touching any values.

Checklist if it is still not fixed

• Restart Riot Client and confirm the update finished.
• Set the game to your dedicated GPU, update the driver, and if nothing changes, do a clean reinstall with DDU.
• Run the full repair tool, and if it fails, check for 8GB or more of free space and leftover League processes.
• See whether the symptom persists in a clean boot, and disable security software only briefly as a test.
• If any error code or message appears, search that exact text on Riot's support site first.
• Gather logs from the Riot Repair Tool, a video or screenshots of the symptom and any error code, then contact Player Support with Submit A Ticket.

Documenting the symptom, and recording after the fix

Everything above is Riot's own troubleshooting order. A phone video or screenshots of how the symptom unfolds make it easier to explain to Player Support. Once the game launches normally again, DOR is ready to go.

For League of Legends, DOR is a free Windows app that records full matches to mp4 automatically, cuts kills, multikills and objectives into automatic highlight clips, and lets you trim just the scene you want and share it as a dor.gg link.

On a supported NVIDIA card such as the RTX series, DOR records with NVENC hardware encoding. Game sound and microphone are captured together on one track, so your own mic audio from the first match after the restart is kept as well. The setup is covered in how to record League of Legends.
