If you can get a DVI to HDMI adapter cable you should be able to get higher resolutions. I have one connected to an HDMI port on my TV and it really looks good @ 1920x1080.

I think that the PC output looks much better than console equivalents. I played Dragon Age on it for a while. My son brought his 360 and his copy of DA for the 360 when he was in for a visit and the PC version was noticeably better, even on the same display.

The TV has 2 HDMI ports on the back of it, but unfortunately I cannot test this feature because at the moment I only have a netbook with a VGA connection/lead. I wonder how the TV would behave if I used it with an old PC? What I mean is - using DOS on an old PC defaults to 70Hz. Using a new PC and DOSBox runs successfully on the TV at 60Hz. Unfortunately, I don't have access to my old PC hardware at the moment, so I can't test this. If an old PC worked well with the TV, I would then forget about trying to buy a new 4:3 aspect ratio monitor. For one thing, these types of monitors are getting quite rare to buy new.

I think it's great that this TV can be selected to run in "old fashioned" 4:3 aspect ratio mode. Is this a common feature with new modern TVs?

I have mine setup to a KVM with audio/vga/ps2 connected to some old machines works fine, 70 hz works, 4:3 ratio works fine and the tv can do proper fullscreen filling when it goes into some maximum scaling detection mode. The KVM seems capable of sending over 1080p in fairly decent quality as well. Who needs all this hdmi stuff 😀

When using DOSBox on a modern PC, either with a PC monitor or a TV, the 60Hz image is good, clear and sharp. IMO, this is one of the many benefits of using DOSBox. OTOH, when using old DOS with an old PC on an LCD PC monitor, the 70Hz image is not quite as good/clear/sharp as the 60Hz DOSBox image. When you use your old PC hardware with a TV, and it successfully displays its image at 70Hz, do you notice that this 70Hz image is not quite as good/clear/sharp as the 60Hz DOSBox image?

looks fine here, tv just caches a full frame and does it's scaling magic i guess.

The reason I mentioned HDMI was because retro mentioned that he was using a Sony Bravia. Sony doesn't allow the full resolution using the VGA port in the back, only through an HDMI connection. I found that out when connecting a PC to my parent's Sony Bravia and was unable to set to higher resolutions. That was a couple years ago, so maybe the newer model's are different, but in the past DVI to HDMI was the only way to get the full resolution on a Sony Bravia.
