Drivers & Software

[skullius]

I have a Radeon R290X connected with Displayport cable to my Dell P2815Q monitor, and I use it in 2560x1440 instead of the full 4K resolution that the monitor is capable of as my eyes dont like it in 4k. This has been working perfectly, I did have some initial issues in the beginning but after a bit it stabilized and I did not think much about it.

A few weeks back I restart my computer (doesnt happen that often) and all of a sudden everything is super blurry - a real pain to look at. Not only fonts, everything is looking through a haze.

I try to install latest drivers, but this does not help at all, instead I see complains that my resolution is not optimal. After a lot of fiddling with settings all over the place (WHY does the interface have to look so sleek?? isnt it better to be clear about what a setting do and what it affects???) I managed to at least get the resolution I wanted and, I suspect, disable the driver as I not only got the resolution but also the crispness back. However, I could see the Radeon interface - but I did not touch anything in there. I have been able to restart a few time without any ill effects.

Yesterday I was forced to restart the computer - and all of a sudden the blurry desktop was back. This time I did not seem to find the settings I used before to get back to crispness - so as a final resort I tried to install the latest 18.3.1 driver. This installation failed - but... all of a sudden my desktop is nice and crisp again. I am guessing this will only be temporary until some update "fixes" my setup.

What can I do to use the driver and have a crisp desktop??

- Install old driver - really? If this was going from 17->18 I could expect that not all things were right the first releases. but this is not 18.0.0
- Fix DPI and font - em, why is my whole desktop then blurry?

Could be many things, but we know it is user created, not graphics drivers.

Do you have GPU scaling enabled?

Morphological filter enabled?

Using a VSR screen resolution? These resolutions are for games only, not everyday desktop use.

Where did you come up with the 2560x1440 resolution?

Dell 28 Ultra HD Monitor P2815Q Review & Rating | PCMag.com

• Pros Affordable. Sharp UHD image. Generous feature set.
• Cons UHD only works at 30Hz. Narrow viewing angles. Skewed greens.
• Bottom Line The Dell 28 Ultra HD Monitor P2815Q is a well-equipped 28-inch Ultra-High-Definition (UHD) monitor with a sub-$600 price. It delivers a highly detailed 4K image, but it can't do it at 60Hz.

What was an issue was playing these games at a resolution of 3,840 by 2,160. As with the ViewSonic VX2880mlBest Price at Amazon, the P2815Q is limited to a 30Hz refresh rate in UHD mode, which results in choppy motion handling and significant screen tearing. If you scale down to a 1,920 by 1,080 resolution, the P2815Q will run at 60Hz, but you'll sacrifice all of that UHD goodness for smoother game play.

I had this very same issue with the flickering screen when something with text was displayed.  I ended up setting the refresh rate to 30Hz and the monitor displayed as expected without flickering after that.
