aCanOfDann Posted April 24, 2023 Share Posted April 24, 2023 I've always used LaunchBox on a small PC Box with my TV as a screen. I've upgraded to a new television recently, Samsung Frame, and now when I run MAME ROMs they are running very slowly - both video and audio seem to be lagging. I haven't made any changes to the computer system, but have also noticed that sometimes when navigating the Microsoft Windows menus, it seems to be a little laggy, but not as evident as with MAME. All of the other systems I have installed seem to be running as before. This seems like a weird issue to me, but wondered if anyone might have experienced something similar and know of a fix. Thanks!

If the new TV is 4K its likely that windows has defaulted to a 30Hz refresh rate, just set it back to 60 (or higher if the display supports that) in the Windows display menu.

neil9000 Posted April 24, 2023 Share Posted April 24, 2023 I also see you say its a small PC, is it a low powered PC? Could simply be that its not powerful enough to drive a 4K display also. Quote Link to comment Share on other sites More sharing options...

neil9000 Posted April 24, 2023 Share Posted April 24, 2023 Also i should add if in fact this is a 4K display and you are coming from a 1080p one it could also be that your HDMI cable isnt good enough, or that the actual HDMI port on the PC is old enough that it cant support the bandwidth of 4K60, in either case dropping to 1080p should allow 60Hz selection again.

aCanOfDann Posted April 25, 2023 Author Share Posted April 25, 2023 Thanks for more tips. I'll keep working on this! Quote Link to comment Share on other sites More sharing options...
aCanOfDann Posted June 24, 2023 Author Share Posted June 24, 2023 I'm coming back to this again. Is it possible to add something into the command for MAME games on a case-by-case basis to 'force' them to run at maximum 1080p? I've been reading MAME forums too, and details about adjusting .ini files. Quote Link to comment Share on other sites More sharing options...
