Anyone have experience with Rapsberry Pi on 4K TV?
I have a 3B+ and a 4. The 3B+ worked fine on my 4K and the 4 4GB worked fine in my arcade, but I ended up switching them so the 3B+ runs the arcade and the 4 is on my TV for emulation.
The problem is everything runs slow. I'd read that's because by default it outputs to match screen resolution, so in this instance 4k. The problem here is nothing runs. Emulationstation runs at about 10fps. According to retroarch it runs at about 3fps in menu. In game it's more like 30-40. It's not unplayable, but it's basically unplayable.
I'm in the process of reinstalling retropie on it now and mucking around with settings, but I just can't get retropie to emulate like I've seen it do in videos. I suspect it's because of the 4K output. I did set config to ignore 4K and manually edited the config to force 1080p, etc. but retroarch still runs like poo.

I have a 3B+ Retropie plugged into a 4K tv and it runs fine. I haven't had to mess with any settings on the Pi to get it to run either, so I don't know what the problem might be. :/ Maybe the hardware is defective?

I haven't tried it on a 4k TV yet.
Maybe grab an image off ArcadePunks and see if that works better?

Running retropie specifically?
Apparently retropie/emulationstation in 4k, along with retroarch, causes frame issues.
So I figured it out, turns out there was a setting I must have had a typo on because I put it back to default, re-entered the settings I had before and it runs fine.
I had the following video options set:
Code: Select all
hdmi_group=1
hdmi_mode=16
Code: Select all
hdmi_ignore_edid=0xa5000080

Also I overclocked it to 1750 as it does have heat sinks and a fan on the case. So we'll see how we go.

Yeah. I got my retropie image from the official site though and set it up myself so that could well be the problem.Skynet wrote: ↑Thu Jul 09, 2020 4:04 pmRunning retropie specifically?

I had the following video options set:Then I added this to the bottom of the config:Code: Select all
hdmi_group=1 hdmi_mode=16
I must have had 1 too many or too few 0s in the mix. From what I understand you can do one or the other, but one is preferable to the other. I just used both and it's running at 1080p 60hz now, which is what I wanted. So... I guess it's sorted?Code: Select all

Yeah none of my pie builds are from the official site as I'd rather download a 128GB than scrape everything myself.Roofus wrote: ↑Fri Jul 10, 2020 1:34 amYeah.
