I'm running it using VNC-Viewer-6.19.325-Linux-x64 from my Linux workstation but have the HDMI output connected to my TV which can only do up to 1080i. tvservice -m CEA shows it supports 6 modes, 3 progressive up to 720x480 @ 60Hz, 16:9; and 3 interlaced with 1920x1080 @60Hz, 16:9 being marked (prefer). The supported CEA modes are 1,2,3,5,6 & 7.
I know it can do mode 5 (the one marked prefer) because I have had various cable boxes and DVD/Blu-ray players connected to it and they all worked once I got them to display 1080i (surprising how many devices don't want to start in a broadcast-standard mode - I wrote a blog post about it).
Raspberry Pi 1080p Or 1080i

more updates: By using a edid file - which clearly shows that the TV supports 1080i and not 1080p, I have got the Pi to boot into a 1920x1080 display with the TV attached. Unfortunately it insists on using 1080p. I confirmed this by using VNC and tvservice -s from a command line.
The limiting factor on increasing speed is the video decoding. With 1080i at 30fps or 720p at 60fps the speedup can go up to around 1.3. Trying to go higher causes jerkiness and slowdown. With 720p at 30fps or 480p, speedup works fine up to 2.0x.
You can purchase an MPEG2 hardware decoder license for Raspberry Pi 3 and earlier. Depending on your tuner this may help your recordings play. I have been able to play 1080p live TV from a DVBS2 connected backend on a PI 2 model B running current Openelec out of the box with no additional licenses or over clocking (Gerdesj (talk) 21:55, 30 August 2015 (UTC))
These builds work with High Definition (HD) 720p and 1080i content on a Raspberry Pi 2 Model B or better. There have been reports that earlier Raspberry Pi models might work with Standard Definition (SD) content and a lower gpu_mem setting.
** NOTE**I am able to get it going on 1080i for some reason, but anything on 1080P or even 720P is tough to get past.I also was able to get to a certain point when i enable hdmi_safe=1 and ACTUALLY LOG IN. However, after entering my credentials, it just goes back to black screen.
For the 1080i/50 clip in hardware, the Vero 4K always screws up 1080p/25; the Pi gets it wrong by default but you can correct the problem by turning Deinterlacing off; and the Shield gets 1080p/25 correct by default.
However, I just looked at a couple of progressive VC1 1080i/50 titles on a Pi and explored disabling deinterlacing via MMAL, and I would say that there is indeed an increase in resolution. So although the auto-select does fine with my library in terms of motion (and resolution is pretty good too), I now have a mechanism for getting the best-possible resolution (at least via the Pi), so thanks @angry.sardine for highlighting that MMAL allows for user input to force weave.
So for some reason on a pi4 kodi isn't giving me the ability to set the display to 1080i. The display I'm using is really flaky and doesn't like any resolutions other than 480p or 1080i - if I set it to 720p the colours go all wrong (it seems to be a hardware issue with the display, I've tried everything with the pi's config.txt and nothing seems to make a difference)
1080i isn't a resolution it's a method of interpolation fields to reduce codec performance drag.From memory if your tv can only play 1080i it wont be able to handle the 1080p resolution. So set it to 720p. So for instance I have it set to 1080p resolution but when I play 4k the videos resoution is 4k but the user interface is 1080p.Also you might want to check kodi forums and maybe even open elec and raspbian ones on how to force resolution.

Hi, I'm currently evaluating on a monthly license whether Emby is usable as a media centre on the raspberry pi 4 8GB.I am currently writing a script to convert my media library. The goal is to have no "on the fly" encoding by providing the original files to my devices who can play them and having a "universal" 1080p encode, which can be played on my older devices. I'm not using the builtin conversion feature for the following reasons:
- I can't "keep originals only if they are 4k, and always convert to 1080p"- Converted files still can't play without conversion (5.1 audio gets converted on the fly to stereo when playing on my chromecast)- It often fails or adds movies twice
- If the video file is in 4k, I copy it to my movie collection and suffix the filename with "- 4K". I want this file to be played for example on my LG smart TV.- For my lower power devices (like chromecast 2, old FireTV stick) I want to create a 1080p version with stereo audio and pretty ok quality. (
However, when I try to play the resulting file in the browser, it is filled with green artifacts (see attachment). On the chromecast using the original emby app, it won't even start at all.How can I make the 1080p encode play? Why is the file size of the encode exploded to 27 GB (as opposed to the 7GB 4k version)? This feels unintuitive to me ?
SD-SDI \/ HD-SDI \/ 3G-SDI to HDMI Converter\r\nYou just purchased a brand new HD-SDI DVR and need to output the video to your television or monitor. Problem is you need to convert your HD-SDI signal to HDMI so that you can view your high definition security cameras. That's where PI Manufacturing's SDI to HDMI converter comes in. The SD-SDI \/ HD-SDI \/ 3G-SDI to HDMI converter from PI Manufacturing is the newest revision HD-SDI conversion line incorporating SD \/ HD-SDI single or dual link mode conversion scaled to HDMI. Resolutions of up to 1080p are supported over the HDMI link for those that want true \"High Definition\". Performance has been greatly enhanced due to an upgraded scaler onboard, allowing for new features such as genlock, color, gamma correction, noise reduction, detail enhancement, aspect ratio selection, pattern generator mode, and multiple language menu support. \r\n\r\nFeatures\r\n\r\nInput from SDI security camera via BNC\r\nOutputs to HDMI monitor or capture card via HDMI jack\r\nCompatible with SD-SDI, HD-SDI, 3G-SDI\r\nInput resolution: 720p \/ 60Hz, 1080i \/ 60Hz,1080p 24 \/ 25 \/ 30 \/ 50 \/ 60Hz\r\nOutput resolution: 720p \/ 60Hz, 1080i 60Hz, 1080p \/ 60Hz\r\nTransmission Distance: 3000m at SDI, 200m at HD, 100m at 3G signal\r\n5V 1A power supply included\r\n\r\nNote: This unit does not support audio\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n\r\n","mpn": "SDI-HDMI-3","sku": "SDI-HDMI-3","brand": "@type": "Thing","name": "PI Manufacturing","offers": "@type": "Offer","priceCurrency": "USD","price": "57","url": " -detail/SDI-HDMI-3","itemCondition": " ","availability": " "}SDI-HDMI-3

Resolution is the measure of pixels in an image. In the context of 720p and so on, the number refers to the pixel height of the image in a 16:9 aspect ratio. So 720p is actually a 1280 x 720 resolution, while 1080p is 1920 x 1080, and so on.
Most web video content will also be produced in at least this resolution, but many TV series and such may not be available in this resolution until a Blu-ray release. (1080p is also the standard resolution of a Blu-ray movie.)
Your TV likely has either 1,920 by 1,080 pixels ("Full HD" 1080p) or 3,840 by 2,160 (Ultra HD or 4K). The signal you're sending it, either from cable/satellite, Blu-ray or some 4K source, is exactly the same number of pixels as your TV (yes, 1080i has the same number of pixels as 1080p).
Last week i was wondering what the difference between 1080p and 1080i was. I found out that they are essentially the same resolution of 1920 by 1080 but they refresh the pixels differently. Now I have a tv from around 2006 or so, wich support 1080i input but not 1080p, why? It supports 720p so it doesnt has to be interlaced. And seeing as it supports 1080i input its also able of drawing 1920 by 1080 pixels on the screen. Does anyone know why my tv doesnt support 1080p?
Nowadays, TVs all display Full HD (FHD) at 1080p for example, like 1920x1080@60. We won't go through interlaced or progressive modes, that's beside the point. Please refer to your display manufacturer's manual for its native resolution.
Feeling lucky, want to save yourself a change of screen resolution? By specifying global.videomode=default, Recalbox will not change the screen resolution before launching an emulator. But beware: this can have a considerable impact on performance.Scaling an image from the emulator's native resolution to 1080p can be very CPU intensive and slow down the emulation. It is not recommended to use the default setting if your monitor can display a resolution higher than CEA 4.
I have prototyped a shield for Arduino Uno that can play high definition 1080p video at up to 60fps.I am hoping for some input and opinions from this forum to help determine if I should have them produced to sell.
