https://community.intel.com/t5/GPU-Compute-Software/intel-uhd-630-eyestrain/m-p/1712029#M1954 <P>Hi, I have this old dell optiplex micro 3070 (Intel® Core™ i5-9500T Processor 9M Cache, up to 3.70 GHz UHD Graphics 630) and wanted to set it up for my kid (not for gaming - he needs it for school: drawing, some photo editing and the rest).</P><P>As I was transferring data to it, I experienced some glitches (looked like <EM>minecraft-style dancing pixels</EM> on the screen and got 2 errors 18a and 18b).</P><P>I talked to ai a bit to see what it suggested and it pointed to both drivers and bios being ancient - dell site confirmed critical updates for my specific model, so I updated the GD, chipset and bios.<BR />It was then that I started working on the pc that I realised my eyes hurt like hell (I don't know if the issue was pre-update, though).<BR /><BR />The picture looks fine - clear, both on 4k display and lenovo monitor with lower res. I tried playing with hdmi cables, using 1.4, 2.0 and then tried DP for Lenovo monitor. No difference.<BR />Played with brightness and contrast enhancement in IGCC, and it does make the screen less abrasive for the eyes. (eyestrain onset in just a matter of minutes)</P><P>Has anyone experienced anything similar? Any ideas? (I've been using 4k display on another pc for years - without any issues)</P><P>Thanks!</P> Wed, 27 Aug 2025 09:42:25 GMT pebbles 2025-08-27T09:42:25Z https://community.intel.com/t5/GPU-Compute-Software/intel-uhd-630-eyestrain/m-p/1712029#M1954 <P>Hi, I have this old dell optiplex micro 3070 (Intel® Core™ i5-9500T Processor 9M Cache, up to 3.70 GHz UHD Graphics 630) and wanted to set it up for my kid (not for gaming - he needs it for school: drawing, some photo editing and the rest).</P><P>As I was transferring data to it, I experienced some glitches (looked like <EM>minecraft-style dancing pixels</EM> on the screen and got 2 errors 18a and 18b).</P><P>I talked to ai a bit to see what it suggested and it pointed to both drivers and bios being ancient - dell site confirmed critical updates for my specific model, so I updated the GD, chipset and bios.<BR />It was then that I started working on the pc that I realised my eyes hurt like hell (I don't know if the issue was pre-update, though).<BR /><BR />The picture looks fine - clear, both on 4k display and lenovo monitor with lower res.
