I bought an LG 34 inch IPS 2560x1080 ultrawide screen monitor and like except it has issues with the display port. When connected through HDMI everything works perfectly. Through the DP, the monitor loses the signal. On bootup it disappears sometime after the windows icon appears. It also disappears if I turn off the monitoir and turn it back on. It seems to not know there is a signal being sent to it. Unplugging and replugging the DP cable restores the image. There is also a sound problem, where it takes three seconds for any video to start playing sound. It's consistently three seconds. That also means short sound notifications never get played because they don't last long enough.
I have returned it twice for replacement to Amazon and all three have had the same problem. LG says it cannot be repaired because the board is not available as a part. They can only replace the monitor. I've done that enough times now to give up.
Being back at square one for a new monitor, what do people recommend? I listed the three resolutions I'm considering. I like the idea of the true 4K resolution because it maintains the 16:9 aspect ratio. However, with the ultrawide it feels as if I have more desktop real estate. On the 4K screens everything is just smaller. If I resize to make it readable then I don't gain any screen space*. With the LG screen I have now, I can tuck something over to the side and still have full-HD for everything else.
The downside to ultrawide is circles can end up looking like ovals. Otherwise everything works well. Even dreams look pretty decent when stretched, although I have to avoid any with earth or moon scenes.
One more thing, it needs to have built-in speakers as I also use it to stream from a Roku stick.
*I can only afford a 27 or 28 inch 4K monitor. Since it would replace my old 27 inch HD, whatever desktop space I gain is at the exoense of readability.
