I do not have enough knowledge to tell how difficult and if it is even possible to do. The current way to restart the gpu is to disable/enable the gpu in the device manager through the SetupAPI interface of windows. That's very windows dependant.

Hi, In the latest beta version, I added a command line tool for scripting that can be used to load dynamically the EDID and perform a restart of the GPU before starting an emulator for example. For example, after generating a binary EDID "edidfile.bin" with switchres, you can use an elevated...

Yes, he was one of the first beta tester to get a board a year ago. I sent him the communication protocol to control the board half a year ago, but unfortunatly he does not have time to add the support for the board.

This is something to be done within switchres library but I do not have the knowledge to do it yet. I am planning to make a small console tool on Windows (no GUI) to download an EDID using the serial port, or perform a restart of the graphics adapter easily so that it can be scriptable. On the...

For now I support modelines editing if you copy paste in a custom resolution block, but it is limited to 3 résolutions max. I need to extend this to import a list of modeline from a text file.

Since my last message, I have made a new beta firmware that make the EDID eprom emulation a lot more compatible with most gpu, and that allows to load a 512 bytes binary EDID with up to 20 resolutions (most of 15khz superwide resolutions can be stored). For now, this 512 bytes binary EDID must...

Some videos made by me on a ryzen 5, gtx 1060 with display port converter. F355 naomi on Flycast x64 (dev branch): View: https://youtu.be/hd61_H0Tgq4 In The Hunt on MAME x64: View: https://youtu.be/PQBHK5Z4VEs

Some fresh news from the scart output of the VideoAmp board. A user reported that the super resolution EDID perfectly works with VGA output of an Intel IGP of a 4th gen i5 plugged to a Sony CRT TV with RGB scart input : And on a PVM 9L3 (tate rotation) :

A beta tester also tried some recent Teknoparrot games using a GTX960 with displayport to VGA converter with EDID set at 512x384p, on a 24kHz nanao MS9. Some games can work at such a low 4/3 resolution, but other cannot be streched... Below is Initial D 8 infinity Would love that some...

I got some questions from GumGum that I will answer here so that it is shared for everybody. This is not yet possible. If you want to do that, you would still need some tools like Emucrt to tweak the video refresh rate or the vertical resolution (208p, 224p, etc.) to exactly match your native...

It is almost available, we just started a first batch. Send me a personnal message.

Just some fresh info regarding monitor identification (EDID) and 15kHz/24kHz signal. As suggested in GroovyArcade wiki, I tried a DisplayPort to VGA adaptor with EDID passthrough and the result is that it perfectly works with my Nvidia 1060. The board was automatically detected by Windows 10...

We have finished the beta test. May I ask you what monitor you have? If you want a board we can send one to you but the shipping to your place will be overkilled compared to the price of the board itself. I really don't know how to manage that.

I guess I am not clear. When the board is pluggued to your VGA graphics adapter, the EDID emulator will reports that your "monitor" is a 1280x240p (15kHz) resolution display for example, which will enforce your computer/GPU to output such a resolution with 15kHz frequency. This is the same as...

Yes RGBHV only right now. We were looking for Scart input (using an LM1881), but it was tricky to get all kind of inputs (PAL/NTSC) working. See above VGA out is only a passthrough for EDID emulation signals (in this case it is more or less what a programmable EDID emulator does). In...
