Hi, I have the same problem with my Formuler GTV and my Samsung HW-Q950A Soundbar. On the Formuler GTV box I don't see a SDR to HDR option (anymore). I only see the option Always HDR and Adaptive HDR. The setting is on Adaptive HDR. I tried all kinds of different settings but nothing has worked so far.
I have connected my monitor to the Soundbar via the HDMI TV/ARC and my Formuler GTV box to the HDMI 1 connection of the soundbar. My Blu-ray player is connected to the HDMI 2 connection of the soundbar.
When the GTV is connected to the Samsung soundbar, the video displays well when I boot up the GTV from the beginning. When I set the GTV to standby mode and switch the GTV back on again the screen doesn't display properly anymore. Every couple of seconds it shows the screen for a split second and then disappears again. The only remedy is to pull the power plug out of the GTV and start it up again. Then the video will work as long as everything stays switched on. Please help, this problem is very annoying. My Blu-ray player which is also connected via the Soundbar does not cause any problems.
The GTV has one HDMI connection and no optical connections. A direct connection of the GTV box to the TV / monitor is not an option, because then I only have video but no audio. My monitor has one HDMI connection and one DisplayPort connection. The only solution I can think of is a HDMI audio / video splitter and a HDMI to displayport adapter. I connect the splitter to the GTV box and send the audio to the Soundbar and the video directly to the monitor. But this solution shouldn't have to be necessary and is costly as well.
Please advise.
Thanks in advance!
Kind regards,
