   title="NEW - [SKL] 5k tiled display issues (dual DP)"
   href="show_bug.cgi?id=95207">bug 95207</a> after solving modelines detection)

While modelines are properly detected now and native resolution can be set, the
monitor shows corrupted image (see attached photo).

This is reproducible anytime with random level of corruption. So far I have
never been able to get proper stable image. Lower resolutions (via single DP
cable) work fine, so does Windows in native resolution (dual DP).

No interesting messages in the logs either, attached below.

This is Dell UP2715K, a 5k tiled monitor connected via two DP ports on a C236
board running Skylake Xeon.

I'll hang on IRC on #intel-gfx (nick: tbzatek) for direct debugging.</pre>
