Problem with PG258Q (Resolved)

[Chris99]

I really like this monitor, probably my favorite monitor so far. I got a near perfect (in my eyes) panel, no bad backlight bleed, no stuck or dead pixels, great color consistency... The monitor is great. For this reason, I am very reluctant to RMA the monitor if I do not have to. About two weeks ago, I started noticing some weird lines only inside of the Intel Extreme Tuner software, not outside of the app. I didn't think much of it, maybe just an issue with the app. Then, I started to notice it on a particular screen in Battlefront 2. Then, I could have sworn that I noticed it once on the desktop, with no apps running.

I have had the the line on the side of the screen issue too, but that is separate and seems to be an issue with the Gsync module, as a firmware upgrade for Acer units have been fixing that issue. I was not concerned with this issue because it seems to be more of a glitch and changing the resolution fixes it.

To attempt to fix the issue that I described in my first paragraph, I have done:

- Tried three different display port cables.
- Tried two different graphic drivers.
- Clean installed Windows 10 (not because of this issue, but just because I needed to for another reason).
- The problem does not capture on video capturing software like the XBOX DVR software. I had to capture it with my phone.

Yesterday, I installed my PG278Q again and have not had the issue come up again running this monitor.

This problem only flashes on the screen for a spit second at a time, it is not persistent.

Great! Glad they did right by you.

Kind of sad that they didn't send me one with the updated firmware to fix the occasional line on the side of the screen... However, it is a pretty rare issue and easy to fix, was never my main concern.

If it was a sealed box it may have been packaged before the firmware update.

The date on the monitor is April 2017... Not sure if that is before or after the firmware to fix the line issue. Again, not a huge deal, but would have been nice to have that fixed as well.

If it appears to be an issue with the G-Sync module ... does it only get wonky when it runs too hot? If so, you might be able to give it some air to help cool it down. It's designed to rely entirely on (silent) convection cooling, a little (quiet) forced airflow goes a really long way.

My PG278Q started to run a little too hot after 3 years, lol. Repasted the G-Sync module (and cleaned all the dust off that big fat heatsink ASUS put onto it). Bolted a couple of low-noise low-rpm low-power slim black (90x12mm 12V@0.1A) fans onto the chassis exterior and wired them up to a XH-W1209 thermostat/relay module I set at 60C and stuffed inside. Works like a charm now, maybe even better than before. (The ASUS power brick is sufficiently over-rated to run the fans at full power draw, although a higher brightness screen full of white pixels does momentarily dim when the relay engages. Can't hear the rear-mounted monitor fans over the computer itself, although the relay has a slightly perceptible click.)
